Associations Acute gastritis is caused by the ingestion of an irritating substance, such as aspirin, tobacco smoke, or too much food or alcohol. It can also be caused by a bacterial or viral infection or by acute stress. Toxic gastritis results from the ingestion of a corrosive substance such as a poison or an acid. Many cases of mild gastritis can be avoided by good dietary habits. See a doctor if you have severe or chronic gastritis.
Toxic gastritis requires immediate medical attention.
To control mild gastritis, your doctor may prescribe an antacid. If the problem is caused by a drug, a change in medication may be recommended, or the doctor may suggest that you take the drug with food rather than between meals. Treatment of more severe gastritis will depend on the underlying cause. Relief of symptoms Do not eat or consume alcohol while you are nauseous or vomiting . When the symptoms subside, drink small amounts of water or weak tea at frequent intervals.
