There are many causes of low diastolic blood pressure, such as anemia, malnutrition, excessive wasting, hypothyroidism, hyperalgesia, and genetics. Once this low pressure occurs, it is necessary to strengthen exercise, nutrition, rest and regularity of living, and to ensure a relaxed mood. You can eat foods that raise blood pressure, such as wolfberry, yam, red dates, aconite, and reishi. If the effect of food and regular checkups is not significant, you can go to the hospital for a comprehensive physical examination to find out the cause of low diastolic blood pressure, and then individualize the treatment.
