The term gastritis describes a group of conditions that cause inflammation of the lining of the stomach. There are many factors that can cause inflammation of the lining of the stomach. The most common cause of gastritis is infection with the bacteria helicobacter pylori (the same bacterium that causes most stomach ulcers). Helicobacter pylori (H. pylori) live in the stomach and can cause both acute and chronic infection. Other causes of gastritis include injury, regular use of certain pain relievers or drinking an excess of alcohol. All these can irritate the gastric mucosa and contribute to gastritis.
When the symptoms occur suddenly, it is known as acute gastritis. In chronic gastritis, the symptoms occur slowly over time. Symptoms of gastritis can vary from one person to another and in many people, there may be no symptoms. Some of the common symptoms are:
Abdominal pain: There are some characteristic features of abdominal pain in gastritis such as:
Symptoms of severe gastritis: In addition to the symptoms of gastritis, if you have any of the following symptoms, it may be due to severe gastritis.
Symptoms of chronic gastritis: There are no characteristic symptoms of chronic gastritis unless the person develops an ulcer. The person may have severe bloating sensation, bleeding, fever and a progressively increasing feeling of being ill. As blood loss occurs slowly from the ulcer, it may lead to anaemia (loss of red blood cells) over time and you may experience symptoms such as general weakness and loss of energy because of iron deficiency anaemia.
