The three basic tools for completing a bodily examination are medical history, hands-on examination, and diagnostic/laboratory tests.

A medical history is the most foremost part of the bodily examination, especially while the first visit with your physician. It includes a history of habits, lifestyle, house history, and symptoms. Many physicians use health-risk appraisals, detailed questionnaires that contribute facts about condition habits.

This is one area of the bodily examination for which a patient can prepare. By following the guidelines for communicating with your physician presented earlier in this chapter, you can help your physician procure an accurate condition profile. This is foremost because a prognosis can normally be made with only a suitable history and hands-on examination.

The hands-on examination is the second part of the bodily examination. It consists of an examination by touching, looking, and listening.

Physicians can feel or experience for enlarged glands, growths, and tumors with procedures, such as the breast examination, pelvic examination, rectal examination, and hernia examination. Thumping the back and chest lets the physician know whether any fluid has built up in or around the lungs. Tapping a knee for reflexes may spin nervous ideas damage. A stethoscope is the physician's basic listening gadget and is used to listen to the heart, lungs, abdomen, and glands settled near the covering of the skin. Potential problems that can be detected with the stethoscope range from a heart murmur to such conditions as poor circulation, lung infection, intestinal blockage, and an overactive thyroid gland.

Physicians have entrance to a amount of instruments to visually seek for problems. An ophthalmoscope is used to view the brain by looking into the eye. The first sign of some brain diseases is an unhealthy looking optic nerve. Leakage in the blood vessels of the eye may be a sign of diabetes or hypertension. An otoscope is used to seek the ear, particularly the tympanic membrane. The proctoscope and sigmoidoscope are used to seek the rectum and colon. The laryngoscope and bronchoscope contribute a look at the larynx and bronchial tubes.

The last part of the bodily examination includes diagnostic laboratory tests, which may vary from a uncomplicated urinalysis to invasive dye tests. The effectiveness of these tests receives mixed reviews. Tests conducted for exact symptoms may be invaluable in pinpointing disabling conditions. They may be just as critical for what they do not spin as they are for what they do reveal. This can be reassuring to the patient and physician.

On the negative side, many physicians rely too heavily on laboratory tests. Patients often query or acquiesce to more tests than necessary, sometimes more than is good for them. Ten years ago, one fourth of all medical tests contributed small to health. For example, when researchers at the University of California, San Francisco, studied 2000 patients hospitalized for surgery, they found that 60% of the blood tests routinely ordered were unnecessary. Only 1 in about 450 revealed abnormalities, and they were ignored because they were whether not noticed or dismissed as not significant. The researchers accomplished that if a suitable history turns up no hint of a medical problem, habit testing is a waste.

Many times tests are recommended more for the purpose of protecting the physician against medical malpractice suits, rather than for their diagnostic value. This practice, which is called defensive medicine, paints a sobering photograph of the mystery in manufacture medical decisions for doctors and patients alike. A physician may know with 99% certainty a single prognosis but order a test or policy any way as protection against liability should he or she be sued later. Malpractice suits are a reality; they have increased 300% in the past 30 years. Almost two thirds of physicians say that the threat of liability influences them to order extra tests. 28 Of course, patients all the time have the right to decline a prescribed test. It should be a two-way decision in the middle of patient and physician that is based on its Potential for an effective medical intervention.
