What to Do for a Gastritis Flare-Up

The stomach lining is protected by a layer of soft tissue called mucosa. Gastritis occurs when this protective barrier becomes inflamed or irritated, often leading to discomfort. A flare-up is characterized by an acute worsening of symptoms, commonly including a gnawing or burning ache in the upper abdomen, nausea, bloating, and a feeling of fullness after eating small amounts of food. This irritation can stem from various causes, such as bacterial infection, excessive alcohol consumption, or the regular use of certain medications.

Immediate Measures for Acute Relief

When the burning pain of a flare-up strikes, the priority is to quickly neutralize or reduce the stomach acid irritating the inflamed lining. Over-the-counter (OTC) antacids provide rapid, temporary relief by directly neutralizing hydrochloric acid in the stomach. These medications, often containing calcium carbonate or aluminum hydroxide, work almost immediately to coat the lining and reduce the acidity that causes pain.

For a more sustained, though slower, reduction in acid production, OTC histamine-2 (H2) blockers can be helpful. Medications such as famotidine reduce the amount of acid the stomach produces for a longer period than antacids. Proton pump inhibitors (PPIs), such as omeprazole, block the acid-producing pumps in the stomach lining even more effectively, but they are usually reserved for more sustained treatment.

Beyond medication, physical actions can offer relief from acute pain and pressure. Applying gentle warmth, such as a heating pad, to the upper abdomen may help soothe muscle spasms and reduce discomfort. Maintaining an upright position is also beneficial, as lying down can encourage stomach acid to reflux into the esophagus, worsening the burning sensation. Staying hydrated is important, but take small, frequent sips of water or clear, non-acidic liquids instead of large gulps that can distend the stomach.

Essential Dietary Adjustments During a Flare-Up

The stomach lining requires rest and non-irritation to begin healing, making dietary changes central to managing a flare-up. Focus on bland, easy-to-digest foods that put minimal strain on the inflamed stomach. Good choices include simple carbohydrates like plain rice, toast, and oatmeal, which are low in fiber and fat, and non-acidic fruits like bananas and applesauce.

Proteins should be lean and prepared without added fats or strong seasonings, such as boiled chicken breast or steamed white fish. High-fat foods, including fried items, full-fat dairy, and fatty cuts of meat, should be avoided entirely. Fat slows down digestion and keeps the stomach distended for longer, increasing irritation. Spicy foods containing capsaicin, highly processed foods, and foods high in refined sugar can also directly irritate the mucosal lining.

All acidic and carbonated beverages must be eliminated during this acute phase. This includes coffee, citrus juices, tomato products, and sodas, all of which can exacerbate symptoms. Instead of consuming large, infrequent meals that overwhelm the stomach, eat smaller portions more frequently throughout the day to help maintain a more neutral pH balance and prevent overstretching the stomach wall.

Non-Food Lifestyle Factors That Worsen Symptoms

Certain behaviors and common medications can significantly prolong a gastritis flare-up by directly damaging the stomach lining. The primary medication culprit is the use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen. NSAIDs inhibit the production of prostaglandins, which are compounds that regulate the production of protective stomach mucus and bicarbonate. Removing these medications is often the most effective step in allowing the stomach’s natural defenses to recover.

Managing psychological stress is another important, non-dietary factor, as high stress levels can increase stomach acid production. The body’s stress response triggers the release of hormones that lead to increased gastric acid secretion, which then aggravates the inflamed mucosa. Implementing relaxation techniques or simple mindfulness exercises can help mitigate this physiological response during a flare-up.

Smoking should also be avoided, as the chemicals in tobacco smoke weaken the stomach’s protective lining and make it more susceptible to acid damage. Additionally, the timing of meals influences symptom severity. Finish eating at least two to three hours before lying down to allow for proper gastric emptying, as eating too close to bedtime is known to worsen acid reflux and irritation.

Recognizing When Professional Help is Needed

While many flare-ups can be managed with self-care, certain severe symptoms require immediate medical evaluation to rule out serious complications like bleeding or ulceration. Seek urgent medical attention if you experience vomiting blood or vomit that resembles coffee grounds, which indicates active bleeding in the upper gastrointestinal tract. The passage of black, tarry, and foul-smelling stools is another serious indicator of internal bleeding.

Other red flags include severe, unrelenting abdominal pain not relieved by OTC medications or simple measures, or any symptoms accompanied by lightheadedness or dizziness. Less urgent but still concerning signs that warrant a doctor’s visit include symptoms that persist for longer than seven to ten days despite self-care, or unexplained weight loss. These persistent or severe issues may require professional diagnosis, such as an endoscopy, to determine the underlying cause and prescribe targeted treatment.
