You will likely get treated for low blood pressure only if it is causing symptoms or if your blood pressure drops suddenly. Treatment depends on your symptoms, how severe they are, and the reasons for the low blood pressure. Your doctor may have you:
Add more salt to your diet.
Get fluid through an intravenous (IV) line if you are very dehydrated.
Change or stop medicines that lower your blood pressure.
Take medicine to treat the problem that is causing low blood pressure. For example, you may need antibiotics to treat infection or medicines to stop vomiting or diarrhea.
Be sure to talk with your doctor before you add more salt to your diet or make any changes in your medicines.
