Q: 5. My blood pressure is normally 130/70. When I eat anything at all the pressure drops to 80/39 and I get dizzy about 30 minutes later. It takes about 30 to 40 minutes to get back to normal. Can you explain?
A: It sounds like you have a condition known as post-prandial hypotension. After eating, blood is sent to the stomach to help with digestion. If the rest of the body fails to compensate for the blood going to the stomach, low pressure and dizziness can occur. You need to make an appointment to see your doctor to get help.
