When symptoms of general fatigue and lack of energy appear, a comprehensive examination is needed, including blood tests, heart tests, lung tests, nervous system tests, etc., to determine the cause.
1. Blood test
Blood routine: By examining indicators such as red blood cells, white blood cells, platelets, etc., it can be determined whether there are problems such as anemia and infection.
Biochemical examination: including liver function, kidney function, blood glucose, electrolytes, and other items. Abnormal liver function may lead to metabolic disorders in the body, resulting in fatigue. When kidney function is impaired, toxins accumulate in the body, which can also cause fatigue. Both high and low blood sugar can lead to abnormal energy metabolism in the body, causing fatigue.
Thyroid function examination: Thyroid hormones play an important regulatory role in the body's metabolism. When thyroid function declines, the body's metabolism slows down, leading to symptoms such as fatigue, fear of cold, and weight gain; When hyperthyroidism occurs, the body's metabolism accelerates, and symptoms such as fatigue, weight loss, and palpitations may also occur.
2. Cardiac examination
Electrocardiogram: It can check the electrical activity of the heart and determine whether there are problems such as arrhythmia and myocardial ischemia. Arrhythmia can affect the pumping function of the heart, leading to insufficient blood supply to the body and causing fatigue. Myocardial ischemia can also impair heart function and cause symptoms such as fatigue.
Cardiac ultrasound: It can observe the structure and function of the heart, and determine whether there are problems such as heart valve disease and cardiomyopathy. The above-mentioned heart diseases can affect the pumping function of the heart, leading to insufficient blood supply to the body and causing fatigue.
3. Pulmonary examination
Chest X-ray or CT: can check for inflammation, tumors, pneumothorax, and other issues in the lungs. Lung diseases can affect respiratory function, leading to hypoxia and fatigue in the body.
Pulmonary function test: It can evaluate the ventilation and air exchange function of the lungs, and determine whether there are problems such as chronic obstructive pulmonary disease, asthma, etc. These lung diseases can affect the body's oxygen supply and lead to fatigue.
4. Neurological examination
Head CT or MRI: can check for tumors, cerebrovascular diseases, demyelinating diseases, and other neurological disorders in the brain, which can affect brain function and cause symptoms such as fatigue, dizziness, and limb numbness.
Nerve conduction velocity test: it can check whether there is damage to the peripheral nerve and judge whether there is diabetes peripheral neuropathy, Guillain Barre syndrome and other problems. Peripheral nerve diseases can affect the conduction function of nerves, leading to muscle weakness and fatigue.
5. Tumor examination
If there is suspicion of a tumor, it may be necessary to undergo tumor marker testing. Tumors secrete specific substances that can be detected in the blood, which can consume the body's energy and cause symptoms such as fatigue.
It is recommended to ensure a balanced nutrition and consume sufficient amounts of protein, carbohydrates, fats, vitamins, and minerals. Eat more fresh vegetables, fruits, whole grains, lean meat, fish, etc., and avoid excessive dieting or overeating. Ensure sufficient sleep time every day. Generally, adults need 7-8 hours of sleep, establish good sleep habits, avoid staying up late, and use electronic devices before bedtime. If there are sleep disorders, timely treatment is necessary.
