"Low blood pressure is when the blood pressure range falls below normal. It results in a number of symptoms like dizziness, fatigue, thirst, lack of concentration, fainting and tiredness. There are a number of treatments that will help relieve many of the symptoms. Epsom salt baths, adding salt to your diet, taking vitamins, eating a healthy diet and doing moderate exercise are all proven treatments for low blood pressure."

I knew my blood pressure was low, always has been, but when it was causing considerable difficulty (dizziness, fainting; I have a monitor at home), I did some research. I discovered increasing salt might help, and pretzels are a low cal option.

I drink lots of water, and eat several very salty pretzels. Works for me.
