A minimal blood pressure of 11/7 is optimal for a good health. If your blood pressure is lower, you can take the following measures:
– Add extra salt to your food.
– Drink more water or licorice tea (or take licorice extract in capsules).
– A low dose of fludrocortisone (50-150 microgram a day) can be useful. Fludrocortisone does not have the side effects of synthetic cortisone. It has the effect of aldosterone which increases the blood pressure. Fludrocortisone is only available on prescription.
