Although being old and thin can avoid hypertension, hyperlipidemia, gallstones, diabetes, coronary heart disease, cerebral hemorrhage and other chronic diseases caused by obesity, the thinner the better, the weight of the elderly should not be less than 20% of the standard weight. If there is no special change in diet and living environment, don't take it lightly. The common causes of emaciation in the elderly are: malignant tumor. Any malignant tumor can cause unexplained weight loss, and people who have obviously lost weight recently should be more vigilant. For example, people with a history of atrophic gastritis or gastric ulcer should be careful of gastric cancer. People who lose weight due to dysphagia may suffer from esophageal cancer. The emaciated person with bloody stool, changed stool habits and urgent defecation should not only be regarded as hemorrhoids, enteritis or dysentery, but also those with thin stool, so special attention should be paid to colon cancer and rectal cancer. Diabetes is mostly obesity in the early stage, but over time, increased consumption will lead to emaciation. The emaciation of elderly patients with pulmonary tuberculosis is caused by chronic infection, among which pulmonary tuberculosis is more common. Hyperthyroidism is not uncommon in the elderly, but it is easy to be misdiagnosed. Mainly because the elderly patients without goiter have 1/3, and more than half of them have no exophthalmos symptoms. This disease is mainly manifested in the elderly getting thinner and thinner, often losing appetite, being afraid of heat and sweating, and fidgeting. Drug-induced emaciation Some drugs, such as thyroid preparations and amphetamines, can promote the obvious increase of body metabolism. Taking digitalis, aminophylline, estrogen, erythromycin and sulfonamides for a long time, taking anti-inflammatory and analgesic drugs such as aspirin and indomethacin can reduce appetite, eat less and lose weight. Taking laxatives for a long time will affect the intestinal absorption function and lead to emaciation. Is safety guaranteed?
