Gastritis is irritation and inflammation of the stomach lining. This means the lining is red and swollen. It can cause shallow sores in the stomach lining called erosions. An ulcer is a deeper sore in the lining of the stomach. It may also occur in the first part of the small intestine (duodenum).
The causes and symptoms of gastritis and ulcers are very similar.
Causes and risk factors for both problems can include:
- Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen
- H. pylori bacteria infection
- Tobacco use
- Alcohol use
- Certain other conditions, such as immune disorders, certain medicines, such as high-dose iron supplements, and street drugs, such as cocaine
Symptoms for both problems can include:
- Dull or burning pain in the upper part of the belly
- Loss of appetite
- Heartburn or upset stomach
- Frequent burping
- Bloated feeling
- Nausea with or without vomiting
You likely had an assessment to help find the exact cause and extent of your problem. This may have included a health history, exam, and certain tests.
Results showed that your problem is not from H. pylori infection. You may not need antibiotics as part of your treatment.
Whether your problem is gastritis or an ulcer, you will still need to take other medicines. You will also need to follow instructions to help reduce stomach irritation so your stomach can heal. Your doctor may advise you to quit smoking, vaping, or using other tobacco or nicotine products, and to stop drinking alcohol.
