Liquid antacids are effective for immediate relief of heartburn. Since almost anything that increases pressure in the abdomen can cause heartburn, long-term therapy involves ways of reducing that pressure. Eating smaller meals more often can decrease symptoms. Gastroenteritis is diarrhea, nausea, vomiting, and abdominal cramping brought on by bacteria, amoebas, parasites, toxins, certain drugs, enzymes, or allergens in foods. When an infection is the cause, the doctor may also prescribe an antibiotic.
Chronic gastritis is inflammation of the stomach lining.
It is sometimes caused by eating irritating substances. In elderly people, it is associated with pernicious anemia. Some people with this disorder have no symptoms, but many experience vague pain, a feeling of fullness, loss of appetite, belching, nausea and vomiting. Treatment consists of eliminating the irritating foods, avoiding aspirin, and taking antacids if the condition persists. If pernicious anemia is the underlying cause, the doctor may administer vitamin B12.
