The whole head swelling and unsteady walking can be divided into physiological factors and pathological factors, pathological factors are brain diseases, endocrine diseases and circulatory system diseases. 1. Physiological factors: If you often stay up late or have too much pressure recently, you may experience head swelling and unsteady walking, which is a normal physiological phenomenon, so pay attention to rest and reduce the pressure appropriately, without additional special treatment. 2. Pathological factors: If you suffer from brain diseases, such as cerebellar hemorrhage, cerebellar infarction and brain tumors, etc., the cerebellum will not be able to balance because of the damage, resulting in headache and unsteady walking symptoms. Hypoglycemia may cause this symptom due to insufficient energy supply; circulatory diseases such as posterior circulation ischemia, hypertension and cerebral vasospasm may cause this symptom due to lack of blood supply to the brain, resulting in lack of blood and oxygen. Patients who experience unsteady walking with headache and persistent unrelieved pain are advised to seek prompt medical attention to identify the cause of the problem and treat it aggressively.
