1. Malignant tumor: Any kind of malignant tumor may be emaciated for unknown reasons, and the elderly who have obviously emaciated recently should be more vigilant. For example, elderly people with a history of atrophic gastritis or gastric ulcer should be careful of gastric cancer. Older people who are emaciated due to dysphagia may have esophageal cancer. A emaciated person with bloody stool, changed stool habits and urgent defecation cannot just think that he has hemorrhoids, enteritis or dysentery. Elderly people with thin feces should pay special attention to colon cancer and rectal cancer.
2. Diabetes: Most elderly diabetic patients are obese in the early stage, but with the passage of time, consumption will increase, leading to emaciation.
3. Tuberculosis: Senile emaciation is caused by chronic infection, among which tuberculosis is more common. .
4. Hyperthyroidism: It is not uncommon for the elderly to suffer from hyperthyroidism, 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.
5. Drug-induced emaciation: Some drugs, such as thyroid preparations and amphetamines, can significantly increase the body's metabolism. Long-term use of digitalis, aminophylline, estrogen, erythromycin and sulfonamides, and taking anti-inflammatory and analgesic drugs such as aspirin and indomethacin can reduce appetite, eat less and lose weight. Long-term use of laxatives will affect intestinal absorption function and lead to weight loss.
