If your blood pressure remains constantly low and does not cause any problems it is almost never serious---and does not need to be treated. But if it is associated with symptoms it indicates an underlying problem---and needs treatment.

Your doctor will try to diagnose and treat the underlying medical problem that causes low blood pressure. However the cause of low blood pressure is often not clear.

In many people diet and lifestyle changes can help to treat chronic low blood pressure.
Diet and lifestyle changes that your doctor may recommend to treat low blood pressure include;

  • Diet with more or added salt.
  • Decreased consumption of caffeine.
  • Drinking plenty of nonalcoholic fluids such as about 8 glasses per day (water, juice, rehydration solution, coconut water)
  • Increasing intake of fluids during hot weather, or while you are sick
  • Evaluating your medications (prescription, over-the-counter medications and supplements) to identify the probably cause
  • Engaging in regular physical activity or exercise
  • Caution while rising from a lying down or sitting position.
  • Elevating the head of your bed while sleeping by about 5 to 20 degrees
  • Avoiding lifting heavy objects, straining on the toilet.
  • Avoiding prolonged standing, exposure to hot weather, hot showers and spas.
  • If you have dizziness after eating –eat smaller and more frequent meals and rest after meals.
  • Use of elastic support (compression) stockings if needed

Medications for Low Blood Pressure

If diet and lifestyle changes do not decrease your symptoms due to low blood pressure you may need medication.

Medications which are effective in treating low blood pressure include;

  • Fludrocortisone: Fludrocortisone is a mineralocorticosteroid which is effective for treating low blood pressure and postural hypotension. It helps the body to conserve or retain sodium. This results in fluid retention by the kidneys and improvement of blood pressure.
  • Midodrine: This drug stimulates the receptors in the arterioles (smallest arteries) and veins. This results in increase in blood pressure. Midodrine has been shown to be effective for treatment of chronic low blood pressure and postural hypotension.
