Gastritis is a condition in which the lining of the stomach gets inflamed. The inflammation is usually caused by a bacterial infection and may lead to stomach ulcers too. Acute gastritis occurs suddenly and with intense symptoms. Chronic gastritis occurs gradually, the intensity of the symptoms worsening over weeks.

Signs and symptoms

Gastritis presents as a burning or gnawing pain, like indigestion, nausea, vomiting and bloating in the upper abdomen.

Causes and risk factors

Gastritis occurs when the mucous lining of the stomach is weakened due to caustic stomach acids. Several pre-existing digestive disorders like Crohn’s disease can accelerate gastritis. Bile reflux and bacterial infections can also cause gastritis. Older adults, alcoholics, very stressed people and patients with auto-immune conditions have a greater risk of gastritis.


Gastritis, if left untreated, can cause bleeding and stomach ulcers. In rare cases, chronic gastritis increases the chances of stomach cancer.


Gastritis is diagnosed based on the patient’s medical history, physical exam, an endoscopy to inspect the upper digestive tract and a Barium X-ray. The doctor may also test for bacteria H.Pylori.

Treatment and Surgical Interventions

Gastritis is treated with antibiotics, antacids, proton pump inhibitors or Histamine (H2) blockers or a combination of them.


Gastritis can be prevented by avoiding spicy, fatty or fried foods, alcohol and smoking. Decreasing stress and avoiding unnecessary medications can also be helpful.
