Diet does not raise blood pressure. Low blood pressure should be investigated and the primary disease treated, and in severe cases, medication should be given intravenously to raise blood pressure. Food itself does not have a significant effect on blood pressure and does not have the same therapeutic effect as medication. People with low blood pressure need to eat a good diet and have plenty of nutrients, but it does not have a significant effect on raising the blood pressure level. People with low blood pressure should pay attention to find the cause, for example, patients with insufficient blood volume should pay attention to drink more water to increase blood volume. Patients with severe malnutrition should pay attention to supplemental nutrition, and at the same time clarify whether there are organic diseases, such as severe heart valve disease can lead to low blood pressure, which can be treated by replacing the valve. Food to raise blood pressure is not scientific, low blood pressure people should go to the hospital, under the guidance of physicians to find the cause and treatment.
