Hypertension and hypoglycemia are two different groups of clinical symptoms that appear differently because the organs involved are different. Hypertension is prone to headache, dizziness, tinnitus, and bleeding under the eyes. Hypoglycemia is prone to panic, sweating, hunger, and even loss of consciousness and coma in severe cases. First, hypertensive patients are prone to headache, dizziness, tinnitus and blurred vision in the early stage, usually because hypertension is not controlled and causes complications resulting in damage, mainly due to systemic vascular sclerosis and weakened elasticity. Patients with hypertension should pay attention to a low-salt, light diet, control their weight and keep their blood pressure within the normal range to reduce the appearance of various complications. Because the lesions involved in the brain easily appear brain hemorrhage, cerebral thrombosis; involved in the heart easily occur arrhythmia, heart enlargement, cardiac hypertrophy; involved in the kidneys easily appear renal artery stenosis, and renal failure; involved in the eyes easily appear fundus vascular thinning, and fundus hemorrhage, etc. Second, hypoglycemia hypoglycemia is an emergency and needs urgent treatment. If the patient is conscious, the intake of sugar-containing substances can be given. If the patient loses consciousness, he/she should go to the hospital for intravenous input of glucose as well as glucagon.1. Sympathetic excitation: the patient has panic, sweating (mainly cold sweat), hunger, limb weakness and inattention. Some patients can also have psychiatric symptoms, such as delirium and epilepsy; 2. Central nervous system damage: more serious hypoglycemic symptoms, manifested as the patient’s altered mental state, loss of consciousness and coma. If not rescued in time, the coma time exceeds 6 hours, which may cause irreversible damage and can be life-threatening in serious cases.
