There are many reasons for elevated blood pressure, mainly physiological factors, genetic factors, disease factors and environmental factors. 1. Physiological factors: If you have just finished a strenuous exercise or have a big emotional fluctuation, measuring your blood pressure at this time will result in an increase in blood pressure, which is a normal physiological phenomenon, and can be restored to normal blood pressure after calming down, without special treatment. 2. Hereditary factors: If both parents have hypertension, the probability of the child’s blood pressure will be greatly increased, which is the genetic factor leading to hypertension. 3. Disease factors: If you suffer from cardiovascular diseases, such as aortitis, aortic stenosis and aortic valve insufficiency and other diseases, due to the narrowing of the lumen of the blood vessels, resulting in increased blood pressure. Endocrine diseases such as hyperthyroidism, pheochromocytoma and diabetes mellitus can also lead to fluid imbalance, resulting in increased blood pressure. 4. Environmental factors: If the diet is heavy in oil and salt or excessive fat intake, blood pressure will rise due to elevated lipids; and taking medications can also lead to elevated blood pressure, such as birth control pills or non-steroidal anti-inflammatory drugs. If the elevated blood pressure is relieved for a long time or accompanied by other discomforts, it is necessary to go to the hospital in time for professional consultation and treatment.
