Eat smaller meals
Eating your meals in smaller quantities may help you if you have low blood pressure. The reason is that your blood pressure may drop sharply [7] while your body tries to digest large meals. To avoid this, break up large meals into small, spaced servings.
Cut down on alcohol
Avoid drinking alcohol if you have low blood pressure. Alcohol causes dehydration [8], which can make your blood pressure fall. It is best to cut alcohol out completely because this effect may still be present even if you drink alcohol in moderation.
