Since, like many Americans, you may have been fighting excess body weight for most of your life, you may be heartened to discover that weight loss is a common part of the aging process. However, this weight loss begins when people reach their mid to late 60s, and it usually amounts to only a few pounds a year, if that. Even though your scale says you weigh less, any pounds that are lost due to the aging process are mostly lean body mass or muscle mass, not fat. This leaves most people with less strength than they had just a few years before. Since the process is usually slow, the weight loss usually goes unnoticed except for when they are weighed in at their annual checkup or observe a change in their physical stature.
The time you and your doctor should become concerned about weight loss, however, is when both your weight and your general health rapidly deteriorate over a short period of time. If you have lost 10% of your weight over a period of a month or two, I usually become quite concerned, and the younger my patient, the more concerned I become.
If a person who is quite overweight loses a couple of pounds without trying, the loss might not initially seem serious, but this too can be the sign of a medical problem.
As with the case of malaise, weight loss can occur because of either the normal physiological changes of aging or a more serious illness.
That’s why a complete medical history and physical exam with the necessary diagnostic tests are extremely important in any instance of unexplained weight loss. Thyroid problems may cause you to feel overheated, while cancer or a hidden infection may be responsible for a fever or night sweats. If you are coughing or feel short of breath, you may have emphysema ot lung cancer. There is also the possibility that if weight loss is accompanied by a cough, swollen glands, a fever, and/or a general feeling of malaise, you might have been exposed to the HIV virus, which can lead to the development of AIDS.
If you have tecently lost weight without trying, either a few pounds or 10 or more, you should ask yourself the following questions:
1. Over how long a time has the weight loss occurred?
2. Have I also experienced a change in my appetite or bowel habits?
3. Do I suffer from heat intolerance, nervousness, or heart palpitations?
4. Do I have night sweats, occasional fevers, or newly enlarged glands?
5. Am I coughing a lot lately? Do I suffer from shortness of breath?
6. Do I have a prior history of a serious illness?
7. Do I regularly use alcohol or tobacco?
8. Have I ever had an unsafe sexual encounter, shared a hypodermic needle, or had a blood transfusions?
