Prevention of common metabolic and endocrine diseases in middle-aged men: prevention and treatment of thyroid disorders, diabetes, gout, and heatstroke.

The thyroid gland absorbs iodine and produces thyroid hormones. Thyroid hormones actively promote metabolism. If thyroid hormone secretion is excessive, it's called hyperthyroidism. Hyperthyroidism causes increased nerve excitability and enhanced tissue metabolism, manifesting as an enlarged thyroid gland, irritability, nervousness, increased appetite, palpitations, rapid pulse, heat intolerance, excessive sweating, bulging eyes, and significant weight loss. Hyperthyroidism is a common endocrine disorder in middle-aged men. Heavy work and family burdens and excessive stress in middle-aged men increase sympathetic nerve excitability, leading to an imbalance between the neuroendocrine system and the thyroid gland, resulting in excessive thyroid hormone secretion. Conversely, insufficient thyroid hormone secretion is called hypothyroidism. Symptoms include a dull appearance, cold intolerance, fatigue, eyelid edema, hair loss, poor memory, and in severe cases, edema and coma. The key to preventing hyperthyroidism is maintaining stable endocrine function. Specifically, it's important to maintain an optimistic outlook, properly manage conflicts between family, life, and work, keep a cheerful mood, reduce various pressures, and minimize excessive stimulation of the nervous system to avoid excessive secretion of thyroid hormones. In particular, it's essential to eat plenty of foods rich in B vitamins, avoid excessive alcohol consumption, strong tea, and overeating, and pay attention to the balance between work and rest. Preventing hypothyroidism involves avoiding overwork and cold foods. In areas where endemic goiter is prevalent, iodized salt can be used for prevention and treatment. Diabetes is an endocrine disorder caused by insufficient insulin secretion, leading to disorders in the metabolism of carbohydrates, fats, and proteins, resulting in hyperglycemia and glycosuria. The causes may include viral infections causing a decline in systemic immune function, and insufficient insulin secretion due to obesity, poor diet, trauma, or mental stress. Symptoms include the "three highs and one low": polyuria (excessive urination), polydipsia (excessive thirst), polyphagia (excessive appetite), and weight loss (gradual emaciation), accompanied by fatigue, itchy skin, sallow complexion, decreased vision, and even blindness. Chronic complications include hypertension, heart disease, and cerebrovascular accidents, while acute complications include ketoacidosis and coma. To prevent diabetes, one should: (1) Maintain a regular lifestyle, avoid staying up late, avoid being impatient or angry, maintain a normal weight, and keep blood pressure stable. (2) The culprit of diabetes is excessive intake of sugary foods. Coupled with a lack of exercise, excess heat in the body is converted into fat, which also prevents the sugar in the blood from entering the cells and being converted into heat, thus causing diabetes. Therefore, one should eat less oil and a light diet, try to avoid fried foods, and eat more fresh vegetables and fruits. (3) The disease is caused by a lack of trace elements such as chromium, selenium, and copper in the body, which affects sugar metabolism. Eating whole grains regularly can prevent diabetes. (4) Exercise can increase the effect of insulin and lower blood sugar. Studies have shown that jumping rope for 10 minutes each morning and evening can completely prevent diabetes. This exercise can not only prevent diabetes but also help diabetic patients alleviate their condition. Walking with moderate exercise is the best way to prevent diabetes. Gout is a disease caused by excessive production of uric acid or excretion disorders, which leads to an increase in the concentration of urate in the blood. Medical research suggests that excessive urate crystals can adhere to joints, kidneys, the endothelium of the heart, the endothelium of large blood vessels, and the intracranial cavity, causing related symptoms. Joint pain is the most common symptom, manifesting as redness, swelling, heat, and pain in the fingers, toes, wrists, and knees, with particularly severe pain in the toe joints. This is often accompanied by systemic symptoms such as chills, fever, and headache, and can lead to joint deformities. In severe cases, it can cause kidney stones, renal colic, kidney failure, and even death. A diet high in purines, excessive alcohol consumption, and obesity are major causes of elevated blood uric acid levels. Therefore, preventing gout requires attention to weight loss, limiting alcohol consumption, and a balanced diet. A diet rich in vegetables and fruits, including mushrooms, seaweed, beans, lotus root, and walnuts, is recommended. Limit consumption of animal organs and fermented bean curd. Drink plenty of water to flush out excess uric acid and accumulated salts through urine. Additionally, maintaining a balance between work and rest, avoiding overexertion, and engaging in appropriate physical exercise are also important to lower blood uric acid and urate crystal concentrations. Working in high-temperature environments hinders the body's heat dissipation, especially for those with poor physical condition, those engaged in strenuous labor, those in high-humidity environments, and those with poor ventilation, increasing the risk of heatstroke. Diagnosing heatstroke is not difficult; symptoms such as profuse sweating, dizziness, palpitations, and thirst are early signs. If accompanied by fever, nausea, vomiting, and paleness, the likelihood of heatstroke is even greater. Mild heatstroke can be relieved by leaving the high-temperature environment, drinking cool beverages or cool, lightly salted water, and resting in a cool, well-ventilated place. Severe heatstroke may cause fainting, convulsions, high fever, and shock, potentially endangering the patient's life. Immediate rescue and treatment are crucial, including cooling, intravenous fluids, and other symptomatic treatments. Use cold water or alcohol (ethanol) to wipe the body, or place ice packs on the head, armpits, and groin. If the patient faints, acupressure on the Renzhong acupoint and acupuncture at points such as Shixuan and Neiguan can be applied. Strengthen personal protective measures. Especially for middle-aged and frail individuals, it's important to avoid prolonged exposure to strong sunlight. Adequate rest is crucial during hot seasons. Efforts should be made to improve indoor ventilation. Wear a straw hat to protect your head from direct sunlight during scorching days. Wear white or light-colored clothing in summer. In hot and humid weather, drink plenty of salt water and other cooling beverages. Keep cooling balms or similar remedies readily available for use when necessary. Drinking mung bean soup or porridge can also help relieve heatstroke.
