Normal human blood pressure is 90-139 mmHg systolic and 60-80 mmHg diastolic, once it falls below this range, it falls under the category of hypotension. There are many causes of low blood pressure, such as severe malnutrition, anemia, hypothyroidism, and other endocrine diseases. There are also heart valve disease and coronary artery disease, which can cause low blood pressure. Once hypotension occurs, in addition to going to the hospital to actively understand the cause of hypotension and actively treat it, you should also regulate your life diet by eating more high-quality protein, such as milk and eggs. In addition, you should also take some blood tonic medicines or foods, such as gum, salvia, wolfberry, safflower and red dates. If the correction of hypotension cannot be achieved by these methods, dopamine as well as epinephrine can also be given to correct the hypotension.
