Gut hormones and blood flow in POTS
Part of Brain & nervous system clinical trials.
This study looks at how gut hormones control blood flow after eating in people with POTS. It may help explain symptoms like dizziness and rapid heartbeat after meals.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been diagnosed with POTS (postural orthostatic tachycardia syndrome) within the last 3 months, or during a screening test.
- Your heart rate increases by at least 30 beats per minute when standing up (40 if you are 18-19 years old).
- You have symptoms of POTS when standing, like dizziness or lightheadedness.
- You are between 18 and 50 years old.
- Your waist measurement is less than 180 cm (about 71 inches).
- You do not have other chronic illnesses, metal implants, or take medications that cannot be paused for 36 hours.

Other trials that look related to this one.
This trial tests a new medication (mirabegron) to help people with POTS (postural orthostatic tachycardia syndrome)—a condition where your heart races and you feel dizzy when standing up. The drug works by activating a specific nerve pathway to help control your heart rate and blood pressure.
This study tests simple body movements (like squeezing your legs or squatting) to see if they help control POTS symptoms. It may offer a non-drug way to manage dizziness and fast heart rate when standing.
This trial tests two medications—guanfacine and cromolyn sodium—to see if they can help people with POTS who have symptoms that started after a specific trigger. It might help if you have not found relief from other treatments.
This pilot study tests a treatment called aVNT for people with POTS. It aims to see if this treatment can help with symptoms like rapid heartbeat when standing up.
This trial tests a gentle, non-invasive treatment for Postural Orthostatic Tachycardia Syndrome (POTS), a condition that causes a rapid heart rate when standing. It combines mild ear nerve stimulation with slow, paced breathing to see if it helps manage symptoms like dizziness and fatigue.
This study tests a non-invasive device that stimulates a nerve near your ear (called the tragus) to see if it can help manage POTS symptoms. It may be an option for people whose POTS has lasted more than 6 months and who do not have other serious health conditions.
