The cause of hypertension is not yet clear, it may be caused by genetic, environmental or disease factors. 1. Heredity: Studies have shown that the incidence of hypertension in women with both parents with hypertension is as high as 46%, so there may be a hereditary factor in hypertension. 2. Environmental factors: People with high salt diets, excessive cholesterol intake, chronic stress, or long-term smoking have a higher incidence of hypertension. 3. Disease factors: Kidney disease, hyperthyroidism, hypothyroidism, valvular disease, arterial stenosis, or craniocerebral injury have been known to cause hypertension. 4. Others: High body weight (obesity) or long-term use of birth control pills can induce high blood pressure. If you feel unwell, you should go to the hospital in time, and under the guidance of the physician, give targeted treatment after clarifying the cause.
