Gastritis
Gastritis is not a single disease, but several different conditions that all have inflammation of the stomach lining. Gastritis can be caused by drinking too much alcohol, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen, or infection with bacteria such as Helicobacter pylori (H. pylori). Sometimes gastritis develops after major surgery, traumatic injury, burns, or severe infections. Certain diseases, such as pernicious anaemia, autoimmune disorders, and chronic bile reflux, can cause gastritis as well. The most common symptoms are abdominal upset or pain. Other symptoms are belching, abdominal bloating, nausea, and vomiting or a feeling of fullness or of burning in the upper abdomen. Blood in your vomit or black stools may be a sign of bleeding in the stomach, which may indicate a serious problem requiring immediate medical attention.
Gastritis is diagnosed through one or more medical tests:
- Upper gastrointestinal endoscopy. The doctor eases an endoscope, a thin tube containing a tiny camera, through your mouth (or occasionally nose) and down into your stomach to look at the stomach lining. The doctor will check for inflammation and may remove a tiny sample of tissue for tests. This procedure to remove a tissue sample is called a biopsy.
- Blood test. The doctor may check your red blood cell count to see whether you have anaemia, which means that you do not have enough red blood cells. Anaemia can be caused by bleeding from the stomach.
- Stool test. This test checks for the presence of blood in your stool, a sign of bleeding. Stool test may also be used to detect the presence of H. pylori in the digestive tract.
Treatment usually involves taking drugs to reduce stomach acid and thereby help relieve symptoms and promote healing. (Stomach acid irritates the inflamed tissue in the stomach.) Avoidance of certain foods, beverages, or medicines may also be recommended. If your gastritis is caused by an infection, that problem may be treated as well. For example, the doctor might prescribe antibiotics to clear up H. pylori infection. Once the underlying problem disappears, the gastritis usually does too. Talk to your doctor before stopping any medicine or starting any gastritis treatment on your own.

Indigestion
Indigestion, also known as upset stomach or dyspepsia, is discomfort or a burning feeling in the upper abdomen, often accompanied by nausea, abdominal bloating, belching, and sometimes vomiting. Some people also use the term indigestion to describe the symptom of heartburn.
Indigestion might be caused by a disease in the digestive tract such as ulcer or gastroesophageal reflux disease (GERD), but for many people, it results from eating too much, eating too quickly, eating high-fat foods, or eating during stressful situations. Smoking, drinking too much alcohol, using medications that irritate the stomach lining, being tired, and having ongoing stress can also cause indigestion or make it worse.
Some people have persistent indigestion that is not related to any of these factors. This type of indigestion—called functional or nonulcer dyspepsia—may be caused by a problem in the muscular squeezing action of the stomach (motility).
To diagnose indigestion, the doctor might perform tests for problems, like ulcers. In the process of diagnosis, a person may have x rays of the stomach and small intestine or undergo endoscopy, in which the doctor uses an instrument to look at the inside of the stomach.
Avoiding the foods and situations that seem to cause indigestion in some cases is the most successful way to treat it. Heartburn caused by acid reflux is usually improved by treatment with antacids, H2-blockers, or proton pump inhibitors. Smokers can help relieve their indigestion by quitting smoking, or at least not smoking right before eating. Exercising with a full stomach may cause indigestion, so scheduling exercise before a meal or at least an hour afterward might help. To treat indigestion caused by a functional problem in the digestive tract, the doctor may prescribe medicine that affects stomach motility.
Because indigestion can be a sign of, or mimic, a more serious disease, people should see a doctor if they have
- vomiting, weight loss, or appetite loss
- black tarry stools or blood in vomit
- severe pain in the upper right abdomen
- discomfort unrelated to eating
- indigestion accompanied by shortness of breath, sweating, or pain radiating to the jaw, neck, or arm
- symptoms that persist for more than 2 weeks
