I've had some super low blood pressure, so much I almost fainted. The thing that helped me the most was potassium-rich foods. Avocado and swiss chard are especially good for potassium! Also potato (with skin might be important, I'm not sure), acorn squash, bananas oranges. You can Google it. Any electrolytes wlil bring blood pressure up. For a while, I was carrying salt pills with me in case I needed one, but too much salt gets hard on my stomach. Potassium is wonderful for so many things in the body and it turns out most people are low in potassium.
