Gastritis: symptoms, causes and care

Gastritis is inflammation of the stomach lining that can cause upper abdominal discomfort, nausea, and indigestion.

The lining normally protects stomach tissue from digestive acid. When it is irritated or inflamed, symptoms may appear suddenly or develop gradually. Some people have inflammation with little or no noticeable discomfort.

Gastritis commonly presents with a burning, aching, or gnawing feeling in the upper abdomen. Indigestion, nausea, early fullness, reduced appetite, burping, hiccups, and heartburn can also occur. Symptoms may be more noticeable around meals, but their pattern varies.

Black stools, vomit that looks like coffee grounds, fainting, severe weakness, or chest pain need urgent medical assessment because they may signal bleeding or another serious problem.

A Helicobacter pylori infection can inflame the stomach lining. Anti-inflammatory pain medicines can also reduce the lining's protection, particularly when used regularly. Alcohol, severe physical stress from illness, bile reflux, and immune-related inflammation are other possible contributors.

A clinician considers your medicines, alcohol intake, recent illness, and other symptoms when looking for the likely cause. Treating the cause matters because symptom relief alone may not remove the irritation.

Short-term irritation may settle when the trigger is removed and the lining has time to recover. Ongoing inflammation can continue if an infection, medicine effect, or other cause remains unaddressed. Persistent symptoms deserve review rather than repeated self-treatment.

Regular use of anti-inflammatory pain medicines, heavy alcohol use, a previous ulcer, and infection can increase the chance of stomach-lining irritation. Tell a clinician about blood-thinning medicines, steroids, supplements, and past digestive bleeding, as these details affect safe treatment choices.

Assessment begins with the location and timing of pain, associated symptoms, medicines, and examination findings. A breath test or stool test may help identify Helicobacter pylori. Depending on the symptoms, clinicians may arrange blood tests or use a camera examination of the upper digestive tract to inspect the lining and take samples.

Care is tailored to the cause. Acid-reducing medicines may ease irritation and allow the lining to heal. If testing finds Helicobacter pylori, clinicians may prescribe a treatment course that targets the infection. Do not stop prescribed medicines without checking first; an alternative or protective plan may be needed.

Avoiding alcohol while symptoms are active and limiting non-essential anti-inflammatory pain medicines can reduce further irritation. A clinician can advise which pain relief is appropriate for your situation.

Choose smaller meals if large meals worsen fullness, and notice whether particular foods, drinks, or medicines trigger discomfort. Keep a brief record of symptoms and medicines before an appointment. Seek review if symptoms return after treatment or interfere with eating, sleep, or daily activities.

Inflammation can sometimes be associated with bleeding or an ulcer. Urgent assessment is needed for black stools, vomiting blood or coffee-ground material, severe or worsening abdominal pain, collapse, or new chest pain. These symptoms require prompt evaluation even if you have had gastritis before.

Use anti-inflammatory pain medicines only as directed and discuss regular use with a clinician. Limit alcohol if it aggravates symptoms, follow infection treatment exactly as prescribed, and return for follow-up testing when advised. Hand hygiene and safe food practices may also reduce exposure to some stomach infections.

A GP can assess new or persistent upper digestive symptoms, review medicines, and arrange testing. Referral to a digestive health specialist may be appropriate for bleeding, recurrent symptoms, unexplained weight loss, swallowing difficulty, or findings that need further investigation.
