About Stomach Polyps

Overview

Stomach polyps, also known as gastric polyps, are abnormal growths of tissue that develop inside the stomach. These polyps can vary in size, but most are small, measuring less than 2 centimeters. They are typically benign, meaning they are not cancerous. Stomach polyps are more commonly found in the upper part of the stomach. While some people with stomach polyps may not experience any symptoms, others may have no symptoms at all. It is estimated that about 26% of individuals who undergo an endoscopy have stomach polyps. Diagnosis of stomach polyps can be challenging since they often do not cause symptoms. If you suspect you may have stomach polyps, it is best to speak with a healthcare professional for an accurate diagnosis and appropriate management.

Causes and Risk Factors

The exact cause of stomach polyps are still uncertain, but there are some theories. Chronic stomach inflammation has been linked to the development of gastric hyperplastic polyps. For fundic gland polyps, it is believed that a decrease in gastric acid production may play a role, as this type of polys are more common in individuals who regularly use proton pump inhibitors (PPIs) to suppress gastric acid.

Non-modifiable risk factors are risk factors that cannot be changed. Non-modifiable risk factors for stomach polyps include:

• Age: Older adults may be more likely to develop stomach polyps.
• Gender: Females may have a higher likelihood of having fundic gland polyps, while males may have a higher likelihood of having adenomatous polyps (non-cancerous tumors).
• Family history of cancerous stomach polyps

Modifiable risk factors are risk factors that can be changed or influenced. Modifiable risk factors for stomach polyps are still being studied, but some potential factors include:

• Smoking
• Lack of exercise
• Proton pump inhibitor use
• Having a stomach infection by Helicobacter pylori bacteria

It's important to note that more research is needed to fully understand the modifiable risk factors for stomach polyps. Maintaining a healthy lifestyle and discussing any concerns with your healthcare provider is recommended.

Symptoms

The most common early symptoms of stomach polyps are usually absent, making them difficult to detect without medical tests. However, in some cases, individuals may experience indigestion, acid reflux, heartburn, stomach pain, feeling full quickly, gastrointestinal bleeding, anemia, iron deficiency, and fatigue.

As stomach polyps progress or become more severe, the following symptoms may occur:

• Stomach pain
• Vomiting
• Unexplained weight loss
• Blood in the stool

It's important to note that larger polyps are more likely to cause noticeable symptoms. Consult with your healthcare provider if you experience any concerning symptoms or have any risk factors. They can provide appropriate guidance and recommend further testing if needed.

Diagnosis

To diagnose stomach polyps, doctors commonly perform the following examinations, tests, and procedures:

• Upper endoscopy: This is the most common test for stomach polyps. A thin, flexible tube with a camera on the end is inserted through the throat to examine the esophagus, stomach, and beginning of the small intestine.
• Biopsy: During an endoscopy, doctors may take small tissue samples from the polyp. These samples are sent to a laboratory for microscopic examination to check for cancer cells.
• Endoscopic ultrasound: This procedure involves using a small ultrasound device attached to an endoscope to create images of the inside of the stomach. It helps identify abnormalities and check whether the polyp has spread to surrounding lymph nodes or other areas.
• X-rays: Healthcare providers may use X-rays to examine the inside of the esophagus, stomach, and first section of the small intestine. This can provide additional information about the size and location of the polyps.

It's important to note that these are general procedures and may vary depending on individual cases. Your healthcare provider will determine which tests are necessary based on your specific situation.

Treatment Options

The goals of treatment for stomach polyps depend on the type of polyp and the presence of symptoms. Here are the various treatment options and how they work to achieve those goals:

• Medications:
  • Antibiotics: If stomach polyps are caused by a Helicobacter pylori (H. pylori) infection, antibiotics (medicines that fight bacteria) like clarithromycin, metronidazole, amoxicillin, tetracycline, doxycycline, levofloxacin, and nitroimidazole may be prescribed to treat the infection.
  • Proton pump inhibitors (PPIs): Medications like lansoprazole, esomeprazole, pantoprazole, and rabeprazole can help reduce stomach acid production and relieve symptoms.
• Therapeutic procedures:
  • Polypectomy: For larger polyps or those with dysplasia, a polypectomy may be performed to remove the polyp during an endoscopy procedure.
  • Biopsy: A sample of the polyp is taken and examined under a microscope to determine its type and whether further treatment is needed.
• Health behavior changes:
  • Dietary changes: Certain dietary patterns may help lower stomach acid secretion and potentially affect fundic gland polyps (FGPs). However, research on dietary interventions for stomach polyps is limited.

It's important to note that the specific treatment approach will depend on the individual's condition and should be discussed with a healthcare provider. Medication dosing may be affected by many factors, so it's essential to consult with your healthcare provider regarding dosing (how and when you medication is taken) for your situation. Other side effects can occur, so it's important to consult with your healthcare provider or read the information provided with your medication for additional side effect information.
