How often periodic medical checkups should be carried out?

How often periodic medical checkups should be carried out is best determined by the physician on the basis of what is most suitable for you as an individual rather than on the basis of a general rule. Age is one determinant. The elderly and the very young generally need more frequent examinations than those in between. But other factors must be considered-present state of health, past medical history, family medical history, occupational hazards if any, etc. Your physician will take these into account in deciding what is most appropriate for you -a checkup once a year, or twice a year, or perhaps once in two years.

BETWEEN CHECKUPS Manifestations of illness or impending illness take the form of signs or symptoms, or both. Signs are objective evidence: for example, a change in skin color or the swelling of a body part. Symptoms are subjective: for example, nausea or pain.

They can vary greatly, of course, from mild' and fleeting to severe and persistent. All deserve attention, though it is likely that if they are mild and transient the reason for them is inconsequential. Any persistentor recurring sign or symptom deserves action. Even if mild it should not be ignored. Passing it off as something not worth notice except by a hypochondriac is dangerous.

 You may become so habituated to its presence that you regard it as something "normal" for you-until the underlying problem reaches a stage where it is irreversible or leads to serious consequences. The following discussion is intended to help you interpret the significance of signs andsymptoms that may appear between checkups, as a guide to when to consult your physician without delay.
