Bariatric Surgery and Ulcers
While the benefits far outweigh the risks, all bariatric surgeries come with some degree of risk, even for minor postoperative issues. For example, some bariatric patients may face issues with stomach ulcers after surgery. Let's take a moment to consider why this happens and what can be done about it.
Quick Answer: Can Bariatric Surgery Cause Ulcers?
Ulcers can occur after bariatric surgery. After gastric bypass, a marginal ulcer may develop near the connection between the stomach pouch and the small intestine. Symptoms may include upper abdominal pain, nausea, vomiting, difficulty eating, or signs of gastrointestinal bleeding.
- Common symptoms: burning abdominal pain, nausea, vomiting, or discomfort after eating.
- Important risk factors: smoking, NSAID use, certain medical conditions, and surgical or anatomical factors.
- Diagnosis: evaluation may include laboratory tests, H. pylori testing, or an upper endoscopy.
- Treatment: often includes acid-reducing medication, protection of the stomach lining, and management of contributing risk factors.
- Urgent warning signs: vomiting blood, black tar-like stools, dizziness, or sudden severe abdominal pain.
What Is an Ulcer?
Ulcers are sores that develop when the lining of the stomach or intestines becomes deeply eroded. They can develop regularly regardless of undergoing weight loss surgeries, but people who undergo bariatric procedures may face an increased risk of developing an ulcer.
This can happen soon after surgery or years after the surgery is performed. Ulcers can occur in the stomach, where they are called gastric ulcers, or in the duodenum at the beginning of the small intestine, as a duodenal ulcer. They can be tiny or be an inch in size or more. They often result from an infection with Helicobacter pylori (H. pylori) bacteria or from taking non-steroidal anti-inflammatory drugs (NSAIDs) for a long period.
What Causes an Ulcer After Bariatric Surgery?
Ulcers after bariatric surgery are usually caused by a combination of patient-related, medical, and surgical factors. After gastric bypass, marginal ulcers can develop when tissue near the connection between the stomach pouch and small intestine becomes exposed to acid, irritation, reduced blood flow, or delayed healing.
Important contributing factors may include smoking, NSAID use, certain medications, immunosuppression, previous ulcer disease, surgical materials, pouch size, and other anatomical or healing factors. Patients may also be evaluated for H. pylori when clinically appropriate.
Bariatric Ulcer Symptoms and Warning Signs
Symptoms vary depending on the type, location, and severity of the ulcer. Some patients may have mild or intermittent symptoms, while others may develop signs of bleeding or another complication.
- Burning or gnawing pain in the upper abdomen
- Abdominal discomfort after eating
- Nausea or vomiting
- Feeling full sooner than expected
- Difficulty tolerating food
- Vomiting blood or material that resembles coffee grounds
- Black or tar-like stools
- Dizziness, weakness, or unusual fatigue
Symptoms vary depending on where the ulcer is and how old you are. Stomach ulcers may produce few or no symptoms or may cause burning, gnawing pain in the upper middle abdomen that eases when eating or taking an antacid.
Duodenal ulcers tend to cause consistent pain, which may be relieved by eating but often returns two to three hours later. Duodenal ulcers can also cause you to wake at night. If you notice any of these symptoms after your bariatric surgery, be sure to consult with your doctor as soon as possible.
Risk Factors for Ulcers
Some of the most common risk factors for developing ulcers after bariatric surgery include the following:
- Type of Bariatric Surgery Procedure – Ulcers after weight loss surgery tend to be more likely in patients who have undergone gastric bypass surgery or a sleeve gastrectomy.
- Smoking and Use of Tobacco Products – Smoking and tobacco, in general, can lead to issues with recovery and healing time, resulting in a greater chance of an ulcer developing. Additionally, tobacco use can increase the risk of Helicobacter pylori infections.
- Use of Certain Medications – Aspirin, ibuprofen, and anti-inflammatory drugs (NSAIDs) can all cause stomach irritation and disturb the normal repair processes of the body, which makes postoperative ulcers more likely.
- Alcohol Consumption – Alcoholic beverages can irritate the lining of the stomach, making a person more prone to developing an ulcer.
- Drinking Caffeinated Beverages – Caffeine can increase the amount of stomach acid and its potency, which can irritate and worsen an existing stomach ulcer. This is just one of many reasons why caffeine intake should be limited after bariatric surgery.
A healthy diet and proper health practices can go a long way toward preventing an ulcer from forming.
How Are Ulcers After Bariatric Surgery Diagnosed and Treated?
Diagnosis may involve reviewing the patient’s symptoms, medications, smoking history, surgery type, and medical history. Depending on the situation, a medical team may order laboratory tests, H. pylori testing, imaging, or an upper endoscopy to examine the stomach pouch and surgical connection.
Treatment commonly includes a proton pump inhibitor to reduce acid and, in some cases, sucralfate to protect the affected tissue. Patients may also need to stop smoking, avoid NSAIDs under medical guidance, and receive treatment for H. pylori if the infection is present.
Ulcers that cause bleeding, perforation, obstruction, or persistent symptoms may require endoscopic treatment or additional surgery. The appropriate treatment depends on the ulcer’s location, severity, and response to medication.
