Weight Loss and body mechanism

WEIGHT DOES MAKE A DIFFERENCE 

It would be a fallacy to say that obesity is ever the one and only cause of a death. But the association between overweight and excessive death rates is unmistakable. Among overweight men, mortality from all causes is 150 percent that for other men; among overweight women, 147 per- cent that for other women. 

As for individual diseases, insurance statistics show that overweight men and overweight women, respectively, have these excesses of mortality as compared with the general population: 142 and 175 percent for heart attacks; 159 and 162 percent for cerebral hemorrhage; 191 and 212 percent for chronic nephritis (kidney disease); 168 and 211 percent for liver and gallbladder cancer; 383 and 372 per- cent for diabetes; 249 and 147 percent for cirrhosis of the liver; 154 and ) percent for hernia and intestinal obstruction; 152 and 188 percent f or non -cancerous gallbladder diseases. Obvert is associated with many diverse types of health hazards. There are breathing difficulties, since the greater the weight in the chest.

wall, the greater the work involved in breathing. With their increased difficulty in breathing, obese people have less tolerance for exercise. They have a higher rate of respiratory infection than do people of normal weight. They may experience two complications related to their breathing problem: lethargy may develop because of accumulation of carbon dioxide in the blood from decreased ventilation; and as the result of reduced levels of oxygen in the blood, the body, trying to compensate, may produce increased amounts of red blood cells. 

The latter condition, called polycythemia, often is responsible for the ruddy complexion of obese people. It may lead to blood-clotting problems. Heart enlargement and congestive heart failure attributable to obesity have been reported. Many studies have established that more hypertension, or high blood pressure, exists among the obese than among the non-obese, that the obese hypertensive experiences a greater risk of coronary heart disease than the non-obese hypertensive, and that mortality rates for obese hypertensive persons are greater than for others with obesity alone or hypertension alone. Obese people often have impaired carbohydrate tolerance that may be sufficient in degree to be classified as diabetes.

Difficulties during anesthesia and surgery have been associated with obesity. In women with significant degrees of obesity, menstrual abnormalities and abnormal hair growth (hairsutism) have been observed with some frequency. For pregnant women, obesity can be a hazard in several ways: it is associated with a greater incidence of toxemia, of complications during delivery, and of stillbirths. Some skin problems are related to obesity. Thus, the extra surface area of the skin in the obese person may lead to excessive perspiration, and the juxtaposition of moist skin areas in adjacent folds may lead to boils, fungal infections, and other inflammatory conditions.

It has been well established that in many health problems, significant benefits often follow loss of weight. Among such conditions are hyper- tension, angina pectoris, congestive heart failure, varicose veins, rupture of intervertebral disks, osteoarthritis, and many other varieties of bone and joint disease. And certainly not to be omitted from even a partial list, many foot aches and backaches may be relieved to a significant extent, sometimes even completely, by weight loss.

How Your Food Causes illnesses and remedies

THE FOOD YOU EAT IS THERE 

someone food or class of foods with special value for preventing disease? The science of nutrition has much to offer for health but it does not take the form of a panacea food or food combination. The one fact that stands out most clearly as new advances are made is that except for certain specific problems-disease states for which special diets have been definitely established as helpful-the healthiest diet has two basic characteristics: it is balanced and it is varied.

NEW REASONS

FOR BALANCE AND VARIETY One of today's most exciting research stories have to do with investigations into the role of trace elements in health and disease. It has long been known that an amount of iron that would bulk up no bigger than a couple of nails stands between us and suffocation, for iron is an essential part of the blood substance hemoglobin, which carries oxygen to body tissues. But it now seems that many other elements in minute amounts-each constituting at most 1/10,000 of body weight and very often far less- may play significant roles.

Recent studies have suggested that lack of adequate zinc in the diet can delay wound healing and may be a factor in diseases of the arteries. In one investigation, zinc supplements were given to some Air Force men who had undergone surgery. Their surgical wounds healed in less than half the time required in other men who had had the same surgery but did not receive zinc supplements. The results not only demonstrated zinc's role in speeding healing; they suggested that the diet of these airmen may well have been Zinc-deficient.  

Building General Health as Preventive Therapy In a later study, investigators treated with zinc supplements a group of patients who had skin sores that refused to heal. Of the 17 patients in the group, 11 were found to be deficient in zinc, and in all 11 the chronic skin ulcers healed with zinc treatment. The remaining was not zinc- deficient, and although they received the same treatment, their wounds still did not heal. Although the relationship between zinc deficiency and hardening of leg arteries that can block circulation and cause gangrene is not clearly established, some patients who were deficient in zinc and had advanced degeneration of the arteries have shown improvement with zinc therapy. 

How drugs Interacts with our body mechanism? And Outdated Medicines

OUTDATED MEDICINES

 If your physician has prescribed a drug for you and instructs you to discontinue its use before the supply is all gone don't save what is left over for another time. Discard it. It may seem like a waste to throw away expensive medication; actually, it is an important safety precaution. Some drugs lose potency with time; some gain potency. Either way, their use after a lapse of time can be dangerous.

 Moreover, it has become clear that some drugs, in the process of aging, not only change in potency; they undergo marked chemical changes that can make them dangerous. Not long ago, for example, physicians at three New York hospitals reported on several patients who had suddenly experienced nausea and vomiting and then developed symptoms like those of diabetes. The trouble in each case was traced to chemical deterioration of an antibiotic, a tetracycline, taken long after it should have been thrown away.

DRUG INTERACTIONS 

when one medication is being used, the addition of another sometimes can be helpful but sometimes can be harmful. When two agents used in concert do not harmonize, the interaction or interference can cause trouble. Moreover, even effects on dosage requirements must be considered when two or more medicines are being used. Recently, for example, a patient who had had a heart attack and recovered from it was released from the hospital. 

Ten days later, an alarming condition developed. While in the hospital the patient had received an anticoagulant medication as part of treatment-a compound aimed at preventing clotting. At home, he continued as directed to take the same compound in the same dosage. But now the drug was thinning.

 The blood too much

 Something had changed. It had indeed: in the hospital, the patient had been given phenobarbital upon retiring. The sedative, in the course of its activity in the body, had stimulated certain liver chemicals which broke down the anticoagulant faster. At home, without the phenobarbital, the anticoagulant activity continued longer and was more potent. In effect, without the sedative, the patient was getting an overdose of.

The anti-coagulant

The matter, once understood, was quickly adjusted. But it illustrates what is coming to be virtually a new science in medicine, concerned with understanding and taking into account inter- actions between medicines. This, of course, is not the place to go into complex technical details. 

But as indications of how important interaction can be, here are some recent findings: When a patient is taking aspirin, addition of an anticoagulant drug may lead to bleeding. If a patient is receiving a medication such as amitriptyline for mental depression and is also given guanethidine for high blood pressure, the antihypertensive activity of the latter is lost. 

How much is drug overdose? How to measure medicine intake?

With many common sleeping medicines, it is possible to get a 3/4 grain size as well as 1-1/2 grain so

that one of each may be used. For Amy talit there is also a 1 grain size, which many women find is just the right amount. Some men like to take two of the 1 grain capsules and find that this dosage gives them a pleasant night's sleep. 

Delicate assaying of dosage is often possible with liquid medications -for instance, tincture of belladonna, an old standby for stomach cramps and indigestion. Some doctors say, arbitrarily, take 15 or 20 drops.

The expert therapist uses a different approach. His instructions to a patient may go something like this: "1 want you to get the full effect, which is just short of the beginning of toxic symptoms which are dryness of the mouth and blurring of vision. 

So start with 15 drops just before each meal and at bedtime. Then, each day, increase by 1 drop so Ih.,1 you will be taking 16 drops four times a day the second day, 17 A Special Word About Medicine Taking / 41 drops the third day, and so on. Keep increasing until you notice one of the toxic symptoms.

Then drop back by 1 drop each day until there are no toxic manifestations. You may settle on 18 drops or you may need 22, or some other amount. The strength of the tincture may vary slightly from drugstore to drugstore, and sometimes the size of the drops varies too. 

Once you have standardized the dosage you need, keep it and use the same bottle and get the prescription refilled by the same• drugstore." Thus, what seemed like a simple prescription turns out to be some- thing of a scientific experiment. But for you, such experimenting to find exactly the right dose you as an individual need may mean the difference between having and not having disagreeable dyspeptic symptoms. 

Human body reactions to Medicines and Foods Vs Medicines

REACTIONS TO MEDICINES

It may seem unbelievable but there are more than 250 diseases that can be caused by the very medicines designed to treat and cure illness. You may well ask, "Why is this possible?" The reasons are not difficult to understand. Over the past twenty-five years or so, many hundreds of new com- pounds have been developed for treating and preventing disease. Many are powerful and complicated substances.

Their very effectiveness depends upon their great potency and complexity. In some instances, trouble has come unexpectedly because a powerful A Special Word about medicine taking new agents was not tested fully under every conceivable circumstance. Thus, for example, thalidomide seemed to be an excellent and harmless tranquilizing agent in most people, but when it was used by pregnant women it had terrible effects on their unborn children. Another reason for drug-induced illness is that human beings do have tendencies to develop allergic or sensitivity responses. These vary considerably, just as they do for foods. One person may eat eggs until the hens scream for mercy-and enjoy them with impunity; another person, allergic to them, cannot eat one without developing some upset.

And so with other foods

Because of sensitivity problems, a medicine that is highly beneficial for 95 percent of the population may cause trouble, even potentially serious trouble, for the remaining 5 percent. A good example is penicillin, clearly a lifesaving drug. It has, indeed, probably saved well over a million lives since its discovery. But it also has caused severe sensitivity re- actions in scores of thousands of people and has taken the lives of thousands.

As you may have noticed, physicians today inquire carefully about possible previous sensitivity reactions to penicillin before administering or prescribing it. Just as some people, after repeated exposure, become allergic to rag- weed pollen or to poison ivy, so some, after being helped once or even several times by an antibiotic, may develop allergic reactions to the com- pound. Usually the problem is mild-skin rash, hives, or slight fever- and disappears once the drug is stopped. Occasionally, however, there are anaphylactic, or shock like, reactions which are life-threatening, and these can be overcome only if heroic measures-adrenaline and other injections-are used in time.

Still considered the single most valuable antibiotic,penicillin is a major allergy producer because it has been so widely used. It is estimated that 10 percent of Americans have become sensitized to the drug. Still another reason for undesirable reactions is that no drug is 100 percent specific-hitting the bull's-eye, so to speak. In the course of countering the problem for which it is being used, it may produce other effects, and these have to be reckoned with. Consider, for example, the gastrointestinal upsets-cramps, diarrhea, sore mouth, rectal itch-which may occur after use of many antibiotics.

They can come about because of an upset in the natural germbalance in the body. Many harmless bacteria are always present in the gastrointestinal tract. Some, in fact, are essential to digestion; some manufacture vitamins. When a potent antibiotic is introduced to fight infection, it may also decimate this normal bacterial population. Moreover, these friendly bacteria serve another purpose in the body.

Modern Medicines is One of Major Successes, But it Also Includes Disasters

A SPECIAL WORD ABOUT MEDICINE TAKING 

THE HISTORY of modern medicines is one of major successes, but it also includes disasters. Tremendous benefits have followed the discovery of insulin for diabetes, agents for controlling high blood pressure, antibiotics and other anti-bacterial that kill or impede the growth of bacteria, cortisone and other steroid compounds that combat inflammation, tranquilizers and antidepressants for nervous and mentaldisorders, and drugs that slow the wild growth of some cancer cells. But there have been tragedies traceable to indiscriminate use and abuse of such powerful agents and of others. For one thing, no medication yet developed is fool proof-universally useful for even the condition for which it was developed, free of undesirable effects.

Virtually every drug, just as virtually every food, may produce unpleasant effects for at least a few individuals, and so it must be used with care. We hope in this chapter to provide a useful guide to medicine taking, one that will be helpful to you both in more effective treatment of any health problems that arise and also in preventing many problems. 

PRESCRIBING FOR YOURSELF 

A recent survey of a small but typical group of households carried out by a major university research institute found that the number of medications on hand varied from 3 to 88, with a mean of 30. Of the 2,539 medications observed, only 445 were prescription drugs. Each month in the United States, 750 out of every 1,000 adults 16 years of age and over experience a cold, headache, or other illness or  injury for which only 250 will consult a physician.

Thus, people control their own care in terms of whether and when to seek medical aid and when to prescribe for themselves. Virtually everyone on occasion does his own prescribing-and that can be a practical matter. Certainly every minor ache or pain does not require that a doctor be called. Nobody wishes to become a habitual patient. The medicines-variously known as "patent," "proprietary," and "over-the-counter" or "OTC"-which you can purchase in drugstores without a doctor's prescription are generally milder and have fairly broad safety margins. 

Symptoms of Cancer - How to detect Cancer? Answer these questions

CANCER SIGNALS

Some signs and symptoms are commonly associated with cancer. They include: Any lump or thickening in the breast or elsewhere Any sore that does not heal Any persistent change in bowel or bladder habits Persistenthoarseness or coughing Persistent indigestion or difficulty in swallowing Any change in a wart or mole Any sudden weight loss Actually, none of the foregoing constitutes proof of cancer-only that cancer is a possibility which should be investigated without delay.

No sign or symptom-either severe or mild but persistent or recurring -should be neglected, it bears repeating here, on the grounds that it may not mean anything or that the doctor may say it's "just nerves." The preventively minded physician whom you see regularly for your checkups will welcome being consulted about such signals, will not pass them off lightly as "just nerves," will check thoroughly, and, if it should be just a matter of "nerves," will help you do something about the "nerves.

YOUR OWN HEALTH INVENTORY

In addition to regular periodic checkups by your physician and your alertness for danger signals, there is an additional line of defense, an extra safeguard, you can put to use in maintaining health. It consists of a simple inventory of your health, a checklist of statements. Taking the inventory at home will require only a few minutes once a month.

Mark your calendar now to remind you to refer to this chapter and the following statements on some convenient date each month, perhaps the first or fifteenth. If you cannot say "True" to anyone of the statements that follow, you should see your doctor as soon as possible. If you have a perfect "True" score, it is quite likely that your health is being maintained satisfactorily, and you need not see your physician again until your next scheduled examination.

1.            I have noticed no sore on skin, lips, or tongue that doesn't seem to heal.

2.            I am not aware of shortness of breath when walking on level ground or when performing any type of activity that never before made me short of breath.

3.            I am not bothered by indigestion, nausea, appetite loss, abdominal pain or cramps, or the recent sudden appearance of constipation or diarrhea.

4.            I have noticed no blood in bowel movements or urine.

 5.           I am not steadily losing or gaining weight and I am satisfied that my weight is suitable for me.

6.            I do not feel myself becoming nervous, irritable, or depressed. I have had no crying spells and no feelings of overwhelming sadness, worthlessness, mental apathy. I have no persistent feeling that any- body is against me. I do not feel a nervous breakdown coming on.

7.            I do not feel unduly fatigued after little effort, mental or physical. I have no feeling of being rundown.

8.            I have no pallor; my skin color has not changed.  

9.            I have no cough that has persisted longer than a month. I have coughed up no blood.

 10.         I have had no persistent hoarseness.

11.          My hearing remains as good as it has ever been.

12.          My eyesight, too, remains good; I have had no dimming or fogging of vision.

13.          I have no persistent headaches.

14.          I have felt no chest discomfort without obvious cause.

15.          I have had no prolonged aches in back, limbs, or joints.

 16.         There has been no swelling of my feet or ankles.

 17.         I have noticed no urinary changes.

18.          I sleep well. I have no tendency to wake up during the night and have difficulty falling asleep again.

 19.         I have no new persistent pain or any other new symptoms.

20.          I am not worried about the possibility of having a venereal disease. Special for women:

21.          I have noticed no vaginal bleeding at unexpected times.

22.          I have felt no lump in my breast, and I have not been worried about the possibility of cancer or tumor there or in any other part of my body.

23.          I am not troubled with hot flashes. Special for men:

21.          My urination has not been abnormal in any way recently-particularly in terms of difficulty in starting, stopping, dribbling, and pain.

22.          I am not ruptured and have no thoughts that I may be.

23.          I do not believe that I may have picked up some disease overseas during the war which may now be coming to the surface.

Important Note: If you cannot say "True" to one or more of the preceding statements, it does not necessarily mean that you have a serious problem. There may, indeed, be a clue to something serious-and because it is likely to be an early clue, the problem is very likely to be amenable to effective treatment. On the other hand, the problem may be mild, possibly even temporary. But let your physician make the diagnosis for you. He will almost certainly agree that it is good preventive medicine, in the best interests of your continued good health, for him to check up on the lead provided when you cannot say "True" to a statement. – 

How Blood tests helps in finding Urinary problems

Today there are sensitive blood tests for this; they measure the amounts in the blood of certain chemicals, called enzymes, released when the heart is damaged. Urine tests are helpful in detecting kidney disease and other urinary tract disorders and may provide clues to problems elsewhere in the body, such as diabetes. Today, radioactive isotope scanning is a sophisticated and vast new area of testing, useful for the detection of disorders in many different organs. Such scanning is based on the fact that certain chemical elements tend to be deposited in specific organs, and these elements can be made slightly and briefly radioactive; then their distribution in the body can be established with scanning instruments that can pick up their radio-activity and record it on film or paper.

Abnormalities become visible as areas of increased or decreased radioactivity. Scanning now can be used to pick up thyroid problems; brain tumors and abscesses; liver cancer, cysts, and abscesses; lung clots; bone tumors; kidney tumors, cysts, and abscesses; and many more abnormalities including those of the pancreas, spleen, parathyroid glands, and the heart as well. Judicious use of tests has always distinguished the best physicians. It would be a simple matter, of course, for the physician to just order, indiscriminately, a whole battery of tests-at considerable cost of time and money for the patient.

Rather than this, physicians have been selective, using the patient's case history and their personal examinations as guides, determining, from them what problems if any the patient might be likely to have, and, when justified, using supplementary tests to explore these problems. 

How Supplementary Tests are useful along with Blood tests to determine and eradicate diseases?

A chest x-ray to disclose abnormality of the lungs is commonly made. X-ray studies are also used, when considered necessary, to check on heart size and, with the help of barium' either taken by mouth or given by enema, to study the upper and lower gastrointestinal tract. In addition, with the aid of injections of special dyes, x-rays today can be used to study the chambers within the heart and the condition of blood vessels. There is a method of using x-ray, after injection of a dye into an artery leading to the brain, to detect a brain tumor; this technique shows the blood vessel architecture of the brain and where tumor growth has pushed one or more vessels out of normal position. Blood studies have many values.

For a blood count, blood is drawn from a vein in the arm or fingertip, mixed with a diluting fluid, placed in a glass chamber so the number of red and white blood cells can be counted. Red pigment (hemoglobin) in the blood can be determined by comparison with color standards. The proportion of red cells in relation to the rest of the blood can be established by whirling the blood in a centrifuge so that heavier red cells settle in the bottom of a small measured tube called a hematocrit.

 Any departures from normal-such as too little hemoglobin indicative of anemia, too few white cells indicative of inability to combat infection, too many white cells indicative of body response to an infection not otherwise apparent-can are noted quickly.

Blood, usually taken from a vein in small amounts, also may be checked for sugar content as a test for diabetes and for the level of a substance, uric acid, as a test for gout. And sophisticated new blood tests often are valuable for heart problems, supplementing the information provided by the electrocardiogram. The electrocardiogram, a record of the electrical activity of the heart, is useful for analyzing any disturbances of heartrhythm, detecting inflammation, showing damage to the heart muscle, and making other determinations. An electrocardiogram, taken in good health, is of value because it provides a baseline for the future; it establishes what is normal for the individual and allows better interpretation of any changes that occur later. When a heart attack occurs-and many heart attacks are silent-an electrocardiogram will show that it has occurred. But it may not show accurately how much of the heart has been damaged. 

How Blood Pressure Determination helps to find and Prevent diseases?

 

Measuring blood pressure is an even more important part of the medical check today than it was in the past. For one thing, we know now how common elevated pressure is, affecting at least 17 million Americans. For another thing, we know now that high blood pressure, or hypertension, is an important factor in stroke, heart disease, and kidney disease. And best of all, hypertension today almost invariably can be controlled. Blood pressure is simply the push of blood against the walls of the arteries. It is highest when the heart contracts and pumps blood into the arteries and this peak pressure is called systolic. It is lowest when the heart relaxes between beats, and this lower pressure is the diastolic.

To measure pressure, a basically simple, though not simply named, device, the sphygmomanometer, is used. It's an inflatable cuff attached to mercury or other type of meter. When the cuff is wrapped around the arm above the elbow and inflated, the inflation does two things: it drives the mercury column up to near the top of the gauge and it compresses an artery in the arm so no blood flows through. With his stethoscope placed on the artery, the physician listens as he gradually lets air out of the cuff. At some point, as the air is released, the pressure of blood in the artery will begin to exceed the pressure of air in the cuff, and the blood will begin to flow again in the artery.

The beginning of flow produces a thudding sound the physician can hear through the stethoscope, and at this point the mercury gauge shows what the systolic pressure is. Then, as more air is released from the cuff there comes a point when the thudding sound no longer can be heard, and at this point the mercury gauge shows the diastolic pressure. It is normal for pressure to vary somewhat from day to day, even minute to minute. It goes up with excitement, which is why in an examination a physician may wish to take your pressure several times. In some people, however, the blood pressure is nearly always higher than it should be. 

How a Patient History Can be used in Preventive Health Care? follow 1000 posts

It is not essential that you have a detailed knowledge of modern examining and testing procedures. But some awareness of the basic, long-established methods and tests and the newest x-ray and laboratory tools, and what they can do, will be useful.

THE CASE HISTORY

The patient's history, always an invaluable guide in disease diagnosis, is equally valuable in prevention. We have mentioned earlier, in passing, some of the reasons. Occupational data-facts about the work you do and possibly the circumstances under which you do it-may reveal some hazards, physical or psychological, to which you are exposed. An account of family health-the illnesses of parents and grandparents, their longevity, the state of health of brothers and sisters-can provide clues to hereditary strengths and weaknesses.

Your own past illnesses are 'an. important part of the record. Some childhood episodes of illness, if severe, may have left a mark. Rheumatic fever, for example, may strike a child at 15 or earlier and may produce some heart damage. Yet, very often, the effects of the heart damage are not felt until age 35, 40, or even later. A record of the rheumatic fever incident may be of vital importance in accurate diagnosis of a heart condition. 

The case history-which includes what the patient reports about present problems-sometimes, provides the first indication of onset of a serious illness. For example, angina pectoris (chest pain) is associated with coronary heart disease. In coronary heart disease, the coronary arteries feeding the heart muscle become narrowed. There are sophisticated techniques now-including x-ray movies of the coronary arteries -to show up the narrowing. But in some early cases, angina may occur before there are sufficient changes to show up on the x-ray studies.

If in taking the history the physician determines that there have been angina episodes-perhaps after some sudden unusual exertion, perhaps upon leaving the house on a particularly cold morning-he can confirm the anginadiagnosis by giving the patient some nitroglycerin tablets to take when the next incident occurs; and if there is immediate relief of pain, the diagnosis is virtually 99.9 percent certain. During history taking, be accurate, don't make wild guesses, but do report things you may think are only minor, like a sense of just not feeling well. It's important to indicate any change because it may be an early warning of something potentially serious.
