Gastroparesis Management In St. Petersburg, FL

GLP-1 medications such as semaglutide (Ozempic, Wegovy) slow stomach emptying as part of how they work, so a growing number of people on them are showing up with nausea, fullness, and bloating that look like gastroparesis. Recent research has linked these drugs to higher rates of delayed emptying, which is why it has become one of the first things to rule out in 2026. There is more detail on GLP-1 medications and gastroparesis risk on the blog.

If you take one of these medications or recently stopped, that has to be sorted out before any procedure. Medication-driven delays often ease once the drug is adjusted or stopped, which is a very different situation from gastroparesis that needs a procedure to fix. Dr. Grandhige reviews your full medication list and uses the gastric emptying study to tell a drug effect apart from true gastroparesis, so nobody has a procedure for a problem a medication change would solve.

The office is in South Tampa, about a 20- to 30-minute drive from St. Petersburg depending on traffic and whether you take the Gandy or the Howard Frankland bridge. The practice is set up so you are not bouncing back and forth across the water.

Before your visit, send your prior records to info@tampareflux.com so Dr. Grandhige reviews everything first. That means endoscopy reports, any gastric emptying study, pH or manometry results, imaging, and notes from your GI, ENT, or primary care doctor. When a test can be done closer to home in Pinellas, the office arranges it there so your trip to Tampa stays focused.

Most patients are seen within two weeks, and always within four. If your testing is already complete, the plan can often be set at the first visit. If you still need testing, expect two visits about four weeks apart so decisions are based on real results. When a procedure is appropriate, it is performed at HCA South Tampa Hospital with the same team that does these cases regularly.

You can reach the office at 813.922.2920, 9 a.m. to 6 p.m., Monday through Friday. The practice is at 1315 South Howard Avenue, Suite 101, Tampa, FL 33606, in the yellow brick building next to Sally O’Neill’s Pizza, with parking behind the restaurant.

Dr. Grandhige is a board-certified general surgeon who has focused on foregut disease, including reflux, hiatal hernias, achalasia, and gastroparesis, in Tampa Bay since 2009. Focusing on one area is what builds the pattern recognition that decides who will do well with a procedure and who will not.

He earned a biology degree at Johns Hopkins University and his medical degree at the University of Michigan, then completed his general surgery residency, a burn and critical care fellowship, and a fellowship in foregut and minimally invasive surgery at Yale-New Haven Hospital. He is a founding member of the American Foregut Society, a member of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), and a Fellow of the American College of Surgeons. All of his foregut procedures are performed at HCA South Tampa Hospital.
