Weight loss in middle-aged and elderly men: warning signs and self-health monitoring; prevention and screening for hyperthyroidism, tuberculosis, and cancer.

Significant weight loss in middle-aged and elderly men should raise suspicion of underlying wasting diseases such as hyperthyroidism, tuberculosis, or cancer. The possibility of diabetes should not be ignored. While hyperthyroidism is less common in middle-aged and elderly men than in younger men, it can still occur, accounting for over 17% of all hyperthyroidism cases. Hyperthyroidism in middle-aged and elderly men differs significantly from that in younger patients; they may not present with increased appetite, nervousness, or goiter, but rather with other symptoms. Some cases primarily present with cardiac symptoms. Middle-aged and elderly men often have heart disease, and the excessive thyroid hormones significantly increase the burden on the heart, thus making heart disease symptoms more pronounced. Patients may experience irregular heartbeat, tachycardia, angina, or heart failure.

Statistics show that one-third of middle-aged and elderly patients with hyperthyroidism also have hyperthyroid heart disease. However, doctors often only pay attention to cardiac symptoms and overlook the presence of hyperthyroidism. Some patients present primarily with digestive symptoms, such as loss of appetite, even anorexia, and sudden weight loss. This may be related to the common presence of chronic gastritis and achlorhydria in middle-aged and elderly men. Due to reduced food intake and increased energy expenditure, weight loss is generally rapid; some patients lose ten to twenty kilograms in a short period, often leading to suspicion of malignancy rather than considering hyperthyroidism.

Hyperthyroidism is primarily characterized by mental symptoms. Patients may exhibit apathy, depression, and drowsiness, leading people to consider these symptoms instead of hyperthyroidism. However, these symptoms are precisely caused by the severe depletion of the body due to undiagnosed and untreated hyperthyroidism. Hyperthyroidism in middle-aged and elderly men can present with various atypical symptoms. Therefore, if a middle-aged or elderly man is noticeably thin, the possibility of hyperthyroidism should be considered, and he should be taken to the hospital for thyroid function tests as soon as possible.

Tuberculosis causes significant bodily depletion, leading to marked weight loss. In middle-aged and elderly men, especially with pulmonary tuberculosis, the radiographic and clinical symptoms are often atypical, making misdiagnosis easy. Pulmonary tuberculosis in middle-aged and elderly men generally lacks typical symptoms such as afternoon low-grade fever and night sweats; approximately one-quarter of patients are completely asymptomatic. Some patients may experience cough, sputum production, or occasional hemoptysis, but these symptoms are often easily confused with chronic bronchitis. Pulmonary tuberculosis in middle-aged and elderly men is often a relapse of earlier pulmonary tuberculosis, but it is often not visible on chest X-rays. When the tuberculous lesions are atypical, they can closely resemble lung cancer, leading to misdiagnosis. Furthermore, the elderly have lower immunity and weaker responses to external stimuli, often resulting in a negative tuberculin skin test. Therefore, the tuberculin skin test may lose its diagnostic value.

Another type of wasting disease is cancer. While a few cancers and leukemias occur more frequently in young people and children, most cancers are more common in middle-aged and elderly men over 40. Like many other diseases, cancer takes advantage of weakened immune systems. Middle-aged and elderly men are physically weak, and if they experience significant emotional distress or stress, their internal balance is disrupted, their resistance decreases, and they become more sensitive to carcinogens, making them more susceptible to cancer. Secondly, the process from carcinogens acting on human tissues to the onset of disease is lengthy; for example, it takes about twenty years for smoking to cause lung cancer. Since cancer often develops in middle-aged and elderly individuals, and these men often have pre-existing conditions that can mask the early symptoms of cancer.

For middle-aged men, diabetes is one of the three most feared diseases. Excessive foam in urine that doesn't dissipate easily may indicate diabetes. In healthy men, the foam disappears quickly after urination, but in men with diabetes, it doesn't dissipate easily. Also, carefully observe the flow of urine on the toilet bowl. In healthy men, urine flows away quickly after hitting the toilet bowl, but in men with diabetes, it may stick to the bowl and not flow away quickly. Checking urine according to this principle can help detect diabetes early. The same pattern occurs when there is protein in the urine, so special attention should be paid to this.

There is an acupoint called Yongquan on the sole of the foot. You can easily check your health using this acupoint. Light a cigarette and hold it about half a centimeter away from the Yongquan acupoint. A healthy person will feel heat within ten to thirty seconds. If the heat takes longer to feel, or if the sensation differs between the left and right sides, it may indicate an imbalance in the sympathetic nervous system, internal organ fatigue, or some other illness, and a thorough health check should be performed. The lips are a signal of internal organs. The color of the lips can reveal a person's health status, constitution, and diseases. Pale lips in men indicate anemia, purple lips indicate lung disease, black lips indicate liver disease, and red lips indicate fever. For example, if you see slightly red and rough lips in the mirror, and your body feels sore and numb, you should drink more honey and eat grated carrots. In short, the lips are a sign of health.
