How long does medication need to be taken for chronic gastritis?

Chronic gastritis is a common digestive system disease. The treatment course generally lasts 2 to 4 weeks, although the exact duration should be determined based on the severity of the condition and the response to treatment.

The treatment duration for chronic gastritis is influenced by multiple factors, including the severity of illness, the type of underlying cause (such as Helicobacter pylori infection or drug-induced gastritis), individual patient differences, and lifestyle factors.

For simple cases of superficial chronic gastritis, the treatment outcome may be relatively favorable. With medication and daily care, recovery and cure may occur gradually within 1 to 2 months. For chronic gastritis caused by Helicobacter pylori, standard triple or quadruple therapy is usually administered for 1–2 weeks, followed by maintenance treatment to consolidate the therapeutic effect.

For other types, such as chronic erosive gastritis or atrophic gastritis, the treatment course may be longer. These types of gastritis may recur repeatedly during medication, and symptoms may reappear under various triggers even after improvement. Therefore, the duration of medication may sometimes last up to six months or even one year.

It is important to note that regular follow-up examinations should be conducted during treatment to adjust the treatment plan according to the disease condition and to avoid unnecessary long-term medication in order to reduce side effects.
