The occurrence of headache and weakness is mainly considered to be related to poor mental status, hypertension, upper respiratory tract infection, anemia, insufficient blood supply to the brain, and intracranial occupational disease. Patients should go to the hospital for pharyngeal swabs, cranial CT and other related examinations according to their condition to clarify the cause and treat the cause. Common causes and treatments 1, poor mental state: factors such as high work pressure, overwork and little sleep can cause excessive mental tension and excitement in patients, which can lead to headache and weakness. Patients are advised to relax and loosen their spirits, and usually the symptoms can gradually disappear after getting good rest. 2. Hypertension: Due to genetic factors, ageing and poor lifestyle, the incidence of hypertension can increase. Patients may show headache and weakness, in addition to palpitations, tinnitus, arrhythmia and other symptoms. Antihypertensive drugs, such as calcium antagonists, angiotensin-converting enzyme inhibitors, beta-blockers, etc., can be applied under the guidance of a doctor. At the same time, pay attention to improve lifestyle, reasonable rest and rest, and measure blood pressure regularly; 3. Upper respiratory tract infection: due to viral infection, inflammatory substances appear in the organism, stimulating local blood vessels in the head with symptoms such as spasm and microcirculatory disorders, which in turn lead to headache and weakness. At this time, more rest and water should be taken, and drugs such as acetaminophen can be taken for treatment under the guidance of a doctor; 4. Anemia: due to the decrease in hemoglobin concentration, the blood does not carry enough oxygen, and patients can experience dizziness, headache, and weakness. Patients should go to the hospital to draw blood to check the hemoglobin concentration to clarify the diagnosis. Iron supplements can be taken for treatment under the guidance of professional doctors. 5. Insufficient blood supply to the brain: If patients have carotid artery stenosis, history of cerebral infarction and other conditions, the brain is prone to insufficient blood supply and lack of sufficient oxygen, and headache, weakness and other symptoms may also occur. Under the guidance of doctors, anti-platelet drugs and statins should be taken to prevent the blood supply to the brain from being insufficient due to the aggravation of blood vessel stenosis. 6. Intracranial occupying diseases: Some brain tumors can cause headache symptoms because of tumor compression, which constantly pulls the pain-sensitive structures in the skull and leads to headache and weakness. It is recommended that patients can eat light and easily digestible food, such as egg custard, shrimp porridge, etc., so as not to stimulate the stomach and intestines due to dietary discomfort, which may aggravate the discomfort symptoms such as headache and weakness.
