Gastroparesis Treatment Centers In St. Petersburg, FL

Foregut-surgeon care for delayed gastric emptying, about 20 to 30 minutes across the bay in South Tampa.

If you live in St. Petersburg and your stomach empties too slowly, you can see a surgeon who works on the stomach and esophagus every day, a short drive across the bay. Dr. Gopal Grandhige diagnoses gastroparesis with objective testing, not guesswork, and for the right patients he performs endoscopic pyloromyotomy (G-POEM), an incisionless procedure done through the mouth that helps the stomach empty. He is one of a handful of surgeons in the Tampa Bay area who performs it. Just as important, he will tell you plainly when a procedure is likely to help and when it is not.

Gastroparesis, and why the diagnosis has to be right first

Gastroparesis means the stomach empties too slowly with no blockage to explain it. That causes nausea, feeling full after a few bites, bloating, vomiting of food eaten hours earlier, and worse acid reflux (GERD). The catch is that those same symptoms show up in several other conditions, so the first job is proving the problem is gastroparesis and not something else.

The test that does that is a four-hour gastric emptying scan. You eat a bland meal, usually eggs, mixed with a small amount of a radioactive tracer, and a camera tracks how fast your stomach empties over four hours. Shorter versions miss cases, which is why the full four hours is the standard for how gastroparesis is diagnosed.

Two facts change how the scan is read. First, the degree of delay does not track how bad the symptoms feel, so the scan confirms the mechanism rather than scoring the misery. Second, many people with gastroparesis-type symptoms actually have functional dyspepsia and empty normally, which means testing sorts who has delayed emptying from who doesn’t. Medications matter too. Opioids, some antidepressants, and GLP-1 drugs used for diabetes and weight loss (such as semaglutide) all slow the stomach, so they get reviewed before any diagnosis is made. Most cases have no clear cause, some follow diabetes (the most common known cause), and some start after a virus. You can read our full overview of gastroparesis symptoms, testing, and treatments for more detail.

Your gastroparesis treatment options, compared

No treatment cures gastroparesis. Every option manages symptoms, and care usually starts conservative and steps up only if it needs to. National guidance in 2025 moved toward stricter diagnosis and more careful use of procedures, in line with the American College of Gastroenterology’s clinical guideline. Treatment tends to move up a ladder, and each step fits a different patient.

Diet comes first for most people. Smaller, more frequent, low-fat, well-cooked meals are easier for a slow stomach, and skipping carbonation and alcohol helps. A dietitian keeps calories and nutrition up while you adjust.

Medications are the next step. Prokinetics like metoclopramide or erythromycin speed the stomach up, and domperidone is an option that is harder to get in the United States. Anti-nausea medicines such as ondansetron treat the symptom directly. These help some patients, with side effects and limits worth weighing.

Pylorus-directed procedures come in when diet and medication fall short. The pylorus is the muscular valve between the stomach and small intestine, and loosening it lets the stomach drain more easily. That can be done endoscopically with G-POEM, or surgically with a pyloroplasty.

A smaller group considers other paths. Some patients are candidates for gastric electrical stimulation, an implanted device that stimulates the stomach. Dr. Grandhige focuses on endoscopic and pyloric-directed treatment, and when a different approach fits better he says so and points you to the right specialist. For severe disease with malnutrition, a feeding tube protects nutrition, and in rare, life-threatening cases that resist everything else, removing most of the stomach is a last resort.

Even with standard treatment, only a minority of patients get real, lasting symptom relief, which is why matching the treatment to the right patient matters more than the procedure itself. Like achalasia, another motility disorder Dr. Grandhige treats, gastroparesis is managed, not cured, and the plan is built around what your testing actually shows.

Endoscopic pyloromyotomy (G-POEM): who it helps, and who it doesn’t

G-POEM, also called POP or per-oral pyloromyotomy, is an incisionless procedure done entirely through the mouth. Using a flexible endoscope, a small tunnel is made under the pyloric muscle, and the muscle is divided with an endoscopic knife so the stomach can empty. There are no abdominal cuts, it is usually outpatient, and recovery is generally quicker than open surgery. Dr. Grandhige is one of a few surgeons in the region who performs it.

It is for selected patients with confirmed, medication-resistant gastroparesis. That is the whole reason the testing above comes first. If delayed emptying is not what is driving your symptoms, loosening the pylorus will not fix them, so patients whose symptoms trace to functional dyspepsia or another cause are not candidates. Patients with severe weight loss may need their nutrition stabilized first. And it manages symptoms rather than curing the disease, so results vary from person to person.

The surgical alternative, pyloroplasty, divides the same muscle through small abdominal incisions and can be very effective, though opening the valve permanently sometimes brings side effects like bile reflux or looser stools with certain meals. Which one fits depends on your anatomy and your testing. Every procedure is done at HCA South Tampa Hospital with the same operating-room team and Dr. Grandhige’s own physician assistant, so the people in the room know the operation cold.

How the evaluation works, and how fast you can be seen

Before your first visit, Dr. Grandhige personally reviews your records. That means your endoscopy reports, any gastric emptying study, imaging, and notes from your gastroenterologist, primary care doctor, or other specialists. Reviewing it ahead of time means your appointment is spent on answers, not filling out forms or repeating your history again. Email your records to info@tampareflux.com before you come in.

New patients are usually seen within two weeks, and always within four. If your testing is already done, one visit is often enough to confirm the diagnosis and talk through options. If testing is still needed, a second visit about four weeks later reviews the results and settles the plan. When a procedure is the right call, the stretch from consultation to the procedure itself typically runs four to eight weeks, depending on testing and scheduling. Throughout, a dedicated physician assistant is part of every case and stays reachable during recovery, so you are not handed off to someone who has never met you.

Why St. Petersburg patients cross the bay for this

For most of St. Petersburg and Pinellas County, the office is about 20 to 30 minutes away, over the Howard Frankland or Gandy Bridge, in the South Howard (SoHo) district of South Tampa. For a chronic condition that needs follow-up, that is usually simpler than flying to a national center and starting over at every visit.

You will find the practice at 1315 South Howard Avenue, Suite 101, in a yellow brick building next to Sally O’Neill’s Pizza, with parking behind the restaurant. Patients come from across St. Petersburg, Clearwater, and the rest of Pinellas, along with the wider Tampa Bay region. For anyone traveling in, the office coordinates testing efficiently and, when possible, arranges for tests to be done closer to home so you make fewer trips. The point is subspecialty focus without the distance.

Meet Dr. Gopal Grandhige

Dr. Gopal Grandhige is a board-certified general surgeon, fellowship-trained in foregut and minimally invasive surgery at Yale-New Haven Hospital. He earned his biology degree at Johns Hopkins University and his medical degree at the University of Michigan, then completed his surgical residency and fellowships at Yale. He is a Founding Member of the American Foregut Society, a Fellow of the American College of Surgeons, and a member of the Society of American Gastrointestinal and Endoscopic Surgeons.

He has focused only on benign foregut disease, meaning the esophagus, stomach, and diaphragm, since 2009, which is more than 16 years in Tampa Bay. That work also covers silent reflux (LPR), achalasia, and hiatal hernias. He has performed more than 600 fundoplications, more than 600 LINX procedures, and more than 200 TIF procedures for reflux, and all of his surgeries are done at HCA South Tampa Hospital. You can read more about Dr. Grandhige and the practice, and find plain-language articles on testing and treatment on our blog.

Patients and referring physicians, from gastroenterology, ENT, pulmonology, and primary care, consistently point to the same things: a thorough workup, clear explanations with drawings, and a surgeon who recommends a procedure only when it is likely to help. Many arrive expecting surgery and leave with a diagnosis and a non-surgical plan instead.

FAQS

No. Gastroparesis is a chronic condition, and every treatment, from diet to medication to a procedure, is aimed at controlling symptoms rather than curing the disease. The goal is real, durable relief and steady nutrition, set against honest expectations.

The main test is a four-hour gastric emptying scan. You eat a bland meal, usually eggs, containing a small amount of a radioactive tracer, and a camera measures how fast your stomach empties over four hours. An endoscopy is often done during the workup to rule out a blockage and other causes.

G-POEM is for selected patients with confirmed, medication-resistant gastroparesis, which is why testing comes first. If your delayed emptying is real and has not responded to diet and medication, you may be a candidate. If your symptoms come from another cause, or if malnutrition needs to be addressed first, a different plan fits better.

They can. GLP-1 drugs used for diabetes and weight loss, such as semaglutide, slow the stomach on purpose, and so do opioids and some other medications. Because they can mimic gastroparesis, your full medication list is reviewed before any diagnosis is made.

That is common, and it does not mean nothing is wrong. Many people with gastroparesis-type symptoms actually have functional dyspepsia and empty normally, while others have delayed emptying that earlier testing missed. A four-hour gastric emptying study and a careful review of your history help sort out which one you have.

The office is in South Tampa, about 20 to 30 minutes from most of St. Petersburg over the Howard Frankland or Gandy Bridge. Patients come from across St. Petersburg, Clearwater, and Pinellas County regularly.

Many patients are referred by their physician, but you can contact the office directly. Send your prior records ahead of your visit, meaning endoscopy reports, any gastric emptying study, imaging, and notes from other doctors, to info@tampareflux.com so your appointment is spent on answers.

New patients are usually seen within two weeks and always within four. If your testing is complete, the diagnosis and options can often be covered in a single visit.
