I am a much older person, but I have low blood pressure and I know for a fact, the majority of the problem is I don’t drink enough water. But you could try eating watermelon, Jell-O, And soups to get more liquid liquids in your body Along with drinking more water..
I am going to try and follow my advice to you for myself also. 😉
But it’s also a good idea to keep a log of your blood pressure. Hopefully you have a blood pressure machine at home.
