Symptoms and Signs of Gastritis Symptoms, Diet Tips, and Treatment

Doctor's Notes on Gastritis Symptoms, Diet Tips, and Treatment

Gastritis is a term that refers to inflammation of the stomach lining due to any cause. Gastritis may come on suddenly (acute) or develop and persist over time (chronic). There are two main causes of gastritis: infection with a bacterium called Helicobacter pylori (H. pylori) and taking and nonsteroidal anti-inflammatory drugs (NSAIDs).  Other diseases and conditions can less commonly cause the condition.

Some people do not have symptoms of gastritis. When symptoms do occur, signs and symptoms associated with gastritis include stomach pain and burning, nausea, and vomiting. Other possible symptoms include loss of appetite, indigestion, weight loss, belching, and abdominal bloating. The stool may test positive for the presence of blood. Smoking, alcohol use, and caffeine can all aggravate the symptoms of gastritis.
