What is postprandial hypotension?

Postprandial hypotension is a sudden drop in blood pressure that occurs after a meal. This can cause symptoms such as dizziness, lightheadedness, and nausea. In some cases, postprandial hypotension can lead to fainting (syncope).

What causes postprandial hypotension?

After you eat a meal, your body diverts blood flow to your digestive system to help you digest your food. This can cause a drop in blood pressure. In some people, this drop in blood pressure is more severe than in others, leading to postprandial hypotension.

Who is at risk for postprandial hypotension?

Older adults and people with diabetes are at an increased risk for postprandial hypotension. Other risk factors include heart disease, kidney disease, and certain medications (such as diuretics and blood pressure medications).

How is postprandial hypotension treated?

If you experience symptoms of postprandial hypotension, there are a few things you can do to treat it:

* Eat smaller meals more frequently. This can help to reduce the severity of the drop in blood pressure after a meal.

* Drink plenty of fluids. Staying hydrated can help to maintain your blood pressure.

* Get up and move around after a meal. This can help to improve blood circulation and prevent dizziness or lightheadedness.

* Talk to your doctor about your medications. If you are taking medications that may contribute to postprandial hypotension, talk to your doctor about adjusting your dose or switching to a different medication.

When to see a doctor

See a doctor if you experience:

* Frequent episodes of postprandial hypotension

* Symptoms of postprandial hypotension that interfere with your daily activities

* Chest pain, shortness of breath, or palpitations along with postprandial hypotension

Your doctor can help to diagnose the cause of your postprandial hypotension and recommend the best treatment.
