Treatment Options For Gastroparesis In St. Petersburg, FL

Gastroparesis treatment near St. Petersburg starts with one question: is your stomach actually emptying too slowly, and why? A short drive across the bay in Tampa, Dr. Gopal Grandhige treats gastroparesis with G-POEM (also called POP, per-oral pyloromyotomy), an incisionless endoscopic procedure that cuts the pyloric muscle to improve emptying. He is one of only a handful of physicians performing it in the Tampa Bay area. The work begins with confirming the diagnosis through objective testing, not with a procedure.

You don’t need a St. Petersburg address to get specialist gastroparesis care

St. Petersburg patients have a real logistical advantage that most articles skip: the specialist treating refractory gastroparesis is 20 to 30 minutes away, not out of state. Dr. Grandhige’s office sits on South Howard Avenue in Tampa, and patients regularly travel in from St. Petersburg, Clearwater, and across Pinellas County for foregut-focused care.

Here’s why people make the drive instead of staying local. Gastroparesis outcomes depend more on accurate diagnosis and patient selection than on the procedure itself. A surgeon who treats foregut disease every day recognizes which patients will respond to a pyloromyotomy and which won’t, before anything is scheduled. That judgment is the difference between relief and a procedure that didn’t help. Dr. Grandhige has practiced foregut surgery in Tampa Bay since 2009 and treats gastroparesis as part of a practice focused only on the esophagus, stomach, and diaphragm.

For out-of-town patients, the team coordinates testing, scheduling, and follow-up so the process takes as few trips as possible. When a test can be done closer to home in Pinellas, they arrange it there.

What G-POEM actually does

G-POEM improves stomach emptying by cutting the pyloric muscle, the valve between your stomach and small intestine, through an endoscope passed down the mouth, with no incisions on the abdomen. When the pylorus stays too tight, food can’t pass efficiently and stays in the stomach too long. That’s what drives the nausea, bloating, and early fullness.

During the procedure, a flexible endoscope creates a small tunnel under the pyloric muscle, and an endoscopic knife divides the muscle. Because there are no external incisions, hospital stays in published studies tend to run short, often one to a few days, and recovery is generally faster than open or laparoscopic surgery. G-POEM targets the same muscle as a surgical pyloroplasty but reaches it from the inside.

You can read more about how the pylorus and gastric emptying work on our gastroparesis condition page, including the other surgical options for severe cases.

Diagnosis comes first: the gastric emptying study

No procedure is recommended until delayed emptying is objectively confirmed, usually with a gastric emptying study. This is the most useful test for gastroparesis. You eat a light meal containing a small amount of radioactive material (eggs and toast, or oatmeal), and a scanner tracks how fast it leaves your stomach over four hours.

This matters because gastroparesis is commonly mistaken for GERD, IBS, or other overlapping conditions, and several conditions cause the same symptoms without delayed emptying. Operating on the wrong diagnosis is the most reliable way to get a poor result. An upper endoscopy is often done during the workup too; if food is still in the stomach hours after you last ate, that points toward delayed emptying. The diagnostic standard for gastroparesis testing is also detailed by the National Institute of Diabetes and Digestive and Kidney Diseases.

Who G-POEM helps, and who it doesn’t

G-POEM is for refractory gastroparesis, meaning symptoms that persist after diet changes and medication have been optimized, not a first move. Current 2025 gastroparesis guidance from the American Gastroenterological Association recommends trying prokinetic medications like metoclopramide or erythromycin first, and reserving procedures such as G-POEM or gastric electrical stimulation for patients who remain symptomatic after a proper evaluation.

Treatment is usually escalated in steps. Many patients improve with smaller, frequent meals, well-cooked low-fat foods, and avoiding carbonation and alcohol. Medications are the next layer: prokinetics that speed emptying, plus anti-nausea options like ondansetron when needed. G-POEM enters the conversation when those steps fall short and testing confirms the pylorus is the problem. Pyloromyotomy is one escalation path; gastric electrical stimulation (a pacer) is a different one, and which fits depends on your testing and history. Patients with severe malnutrition may need nutritional support before any definitive procedure is safe.

This is the honest version of gastroparesis care: it’s a chronic condition, and treatment is aimed at controlling symptoms, not curing the disease. Setting that expectation up front is part of the job.

What the process looks like, from first call to treatment

Most patients go from consultation to treatment within two visits and four to eight weeks, depending on what testing is already done. Many gastroparesis patients have spent years bouncing between providers, so the practice is built to move efficiently without rushing the diagnosis.

Before your visit, send prior records (gastric emptying studies, endoscopy and pathology reports, imaging, and notes from your GI or other physicians) to info@tampareflux.com so Dr. Grandhige can review everything ahead of time. If your testing is already complete, the diagnosis can often be confirmed at the first visit and a plan set that day. If testing is still needed, the first visit focuses on review and test planning, with a second visit about four weeks later to go over results and decide. The office aims to see new patients within two weeks and almost always within four.

Bringing your records isn’t a formality. In today’s fragmented system, patients are often the most reliable carriers of their own history, and complete records mean fewer repeat tests and a clearer answer faster.

Why a foregut specialist, and not a general practice

Dr. Grandhige is a board-certified general surgeon, fellowship-trained in foregut and minimally invasive surgery, who has focused exclusively on esophagus, stomach, and diaphragm conditions in Tampa Bay since 2009. He completed his surgical residency and foregut fellowship at Yale–New Haven Hospital, earned his medical degree at the University of Michigan, and is a Fellow of the American College of Surgeons, a member of SAGES, and a Founding Member of the American Foregut Society.

You can verify his board certification through the American Board of Surgery and the American College of Surgeons directories, and his license through the Florida Department of Health license lookup. A surgeon should welcome that scrutiny.

Care stays continuous, which matters more than it sounds. The same physician reviews your testing, performs the procedure, and oversees follow-up. A dedicated physician assistant assists in every case and is reachable when questions come up, and much of the office staff has worked with Dr. Grandhige for over a decade. All procedures are performed at HCA South Tampa Hospital, where the surgical team handles these cases routinely. If you also deal with reflux symptoms alongside gastroparesis (the two often overlap), his work on GERD and hiatal hernias comes from the same focused practice.

FAQS

No. The office is in Tampa on South Howard Avenue, a 20-to-30-minute drive from most of St. Petersburg and Pinellas County. Procedures are done at HCA South Tampa Hospital, and the team helps coordinate testing closer to home when possible.

With objective testing, primarily a gastric emptying study that tracks how fast a light meal leaves your stomach over four hours. Symptoms alone aren’t enough, because several conditions mimic gastroparesis without delayed emptying.

G-POEM (per-oral pyloromyotomy, or POP) is an endoscopic procedure done through the mouth with no abdominal incisions. It divides the pyloric muscle to improve emptying, reaching the same muscle a surgical pyloroplasty targets, but from inside the stomach.

No. Diet changes and medications come first. Current 2025 AGA guidance reserves procedures like G-POEM for refractory cases after a proper evaluation. It’s offered when those steps fall short and testing confirms the pylorus is the issue.

Gastroparesis is a chronic condition, and treatment is aimed at improving symptoms rather than curing the disease. The goal is meaningful, lasting symptom relief in patients selected carefully through testing.

The office aims to see new patients within two weeks and almost always within four. From consultation to treatment is typically two visits and four to eight weeks, depending on how much testing is already complete.

Send prior gastric emptying studies, endoscopy and pathology reports, imaging, a medication list, and notes from your other physicians to info@tampareflux.com ahead of time, so your records can be reviewed before the consultation.

If you’re in St. Petersburg or anywhere in Pinellas County and stuck on medications that aren’t working, the next step is a clear diagnosis and a plan built around what your testing actually shows.
