Gastritis is treatable, and most cases improve quickly once the underlying cause is addressed. The word “cure” depends on what type you have: acute gastritis often resolves on its own within days once the trigger is removed, while chronic gastritis requires targeted treatment that can take weeks or months. Either way, the path forward starts with identifying what’s inflaming your stomach lining and then removing or treating that cause.
What’s Actually Happening in Your Stomach
Your stomach wall is protected by a mucus-lined barrier that shields it from its own digestive acids. Gastritis develops when that barrier is weakened or damaged, allowing acid to irritate and inflame the tissue underneath. The inflammation can appear suddenly (acute gastritis) or build gradually over months or years (chronic gastritis).
The most common causes are a bacterial infection called H. pylori and regular use of over-the-counter pain relievers like ibuprofen (Advil, Motrin) and naproxen (Aleve). These drugs, known as NSAIDs, can cause both acute and chronic gastritis by eroding the protective lining with repeated use. Heavy alcohol consumption is another frequent trigger. Less commonly, gastritis is linked to autoimmune conditions, Crohn’s disease, celiac disease, or severe physiological stress like major surgery or critical illness.
Why the Cause Matters for Treatment
There is no single cure for gastritis because the treatment depends entirely on why your stomach is inflamed. If NSAIDs are the culprit, stopping or reducing those medications is the most important step. If H. pylori bacteria are present, you’ll need a course of antibiotics to clear the infection. If alcohol is the trigger, cutting back allows the lining to repair itself. Treating gastritis without addressing the root cause is like mopping a floor while the faucet is still running.
This is why most doctors will want to test for H. pylori before deciding on a treatment plan. The test is simple, typically a breath test, stool test, or blood test, and the result shapes everything that follows.
Treating an H. Pylori Infection
If testing confirms H. pylori, the standard treatment is a combination of antibiotics and an acid-reducing medication taken for 10 to 14 days. Current guidelines from the American College of Gastroenterology recommend against one of the older antibiotic combinations (clarithromycin triple therapy) unless lab testing has confirmed the bacteria are sensitive to that particular antibiotic. Resistance to clarithromycin has become common enough that doctors now typically choose a different combination upfront.
The preferred regimen uses four medications: an acid-reducing drug taken twice daily, plus bismuth (the active ingredient in Pepto-Bismol), tetracycline, and metronidazole, all taken multiple times per day for 14 days. It’s a demanding schedule, and side effects like nausea, metallic taste, and diarrhea are common during treatment. But completion rates matter. Stopping early or skipping doses increases the chance the bacteria survive and become harder to treat.
After finishing the full course, your doctor will likely retest to confirm the infection is gone. Once H. pylori is eradicated, the inflammation typically begins resolving and the stomach lining can heal.
Acid-Reducing Medications
Regardless of the cause, most gastritis treatment includes medication to reduce stomach acid. Lower acid levels give the damaged lining a chance to repair itself. Two main types of drugs do this.
Proton pump inhibitors (PPIs) are the stronger option. They block the acid-producing pumps in your stomach and are the go-to for moderate to severe gastritis. These are available over the counter and by prescription. H2 blockers, like famotidine (Pepcid), are a milder alternative that reduce acid production through a different mechanism. For an active gastric ulcer, famotidine is typically used at 40 mg once daily. For milder symptoms, 20 mg twice daily is a common dose.
PPIs and H2 blockers are meant as short-to-medium-term tools to support healing, not permanent solutions. Once the underlying cause is resolved and symptoms improve, your doctor will usually taper you off.
How Long Healing Takes
Acute gastritis is often surprisingly quick to resolve. If you briefly overdid it with alcohol, NSAIDs, or another irritant, your stomach lining can begin repairing itself as soon as the trigger is gone. Most people with acute gastritis feel significantly better within a few days to a couple of weeks.
Chronic gastritis takes longer. The inflammation has had time to cause deeper tissue damage, and healing is more gradual even after the cause is treated. With proper medication, most cases of chronic gastritis improve noticeably within weeks, but full recovery of the stomach lining can take several months. Sticking with your treatment plan during this period, even after symptoms ease, gives your stomach the best chance to heal completely.
Dietary Changes That Help
What you eat won’t cure gastritis on its own, but the wrong foods can slow healing or trigger flare-ups, while the right choices can ease symptoms and support recovery.
Eating smaller meals every two to three hours tends to be easier on an inflamed stomach than three large meals. Stop eating at least two hours before lying down. Use low-fat cooking methods like baking, steaming, or grilling instead of frying. High-fiber foods are generally well tolerated and may help with symptom relief.
Foods and Drinks to Avoid
- Beverages: coffee (regular and decaf), alcohol, citrus juices, carbonated cola, whole milk, chocolate milk, and caffeinated or mint teas
- Spices: black and red pepper, chili powder, curry powder, mustard seed, and nutmeg
- Foods: fried and fast food, highly processed meats (sausage, salami, bacon, cold cuts), tomato-based sauces, chocolate, citrus fruits, and strongly flavored cheeses
You don’t necessarily need to eliminate every item on this list permanently. Many people find it helpful to cut everything out during the acute healing phase, then gradually reintroduce foods one at a time to identify their personal triggers. Some people tolerate small amounts of coffee just fine once their stomach has healed; others find it’s always a problem.
Lifestyle Changes That Matter
If NSAIDs are part of your routine for pain management, switching to acetaminophen (Tylenol) for general pain relief can remove a major source of stomach irritation. Acetaminophen works differently and doesn’t damage the stomach lining the way ibuprofen and naproxen do. If you need NSAIDs for a chronic condition like arthritis, talk to your doctor about taking them alongside a PPI for protection.
Smoking increases susceptibility to gastritis and slows healing. Alcohol directly irritates the stomach lining, so reducing or eliminating it during recovery gives the tissue space to repair. Stress doesn’t cause gastritis directly, but it can worsen symptoms and delay healing by increasing acid production.
Natural Remedies: What the Evidence Shows
Manuka honey has shown promising results in animal research. In one study, rats treated with manuka honey experienced a 67% reduction in ulcer size, comparable to the results seen with a standard acid-reducing medication. The honey appeared to work by reducing inflammation (lowering key inflammatory markers by 20 to 59%) while simultaneously boosting the stomach’s natural antioxidant defenses. However, these results come from animal studies using carefully controlled doses. Human clinical trials haven’t yet confirmed whether eating manuka honey produces the same effect in people.
Ginger, chamomile tea, and licorice root are commonly recommended in traditional and integrative medicine for stomach inflammation, but robust clinical evidence for their effectiveness against gastritis specifically remains limited. They’re unlikely to cause harm in moderate amounts and some people find symptom relief from them, but they shouldn’t replace proven medical treatment, especially for H. pylori infection or severe inflammation.
Warning Signs That Need Immediate Attention
Most gastritis is uncomfortable but not dangerous. However, untreated or severe gastritis can progress to bleeding ulcers, which require urgent medical care. Seek help right away if you notice black or tarry stools, red or maroon blood in your stool, vomit that contains red blood or looks like coffee grounds, or if you feel unusually lightheaded, short of breath, or exhausted without explanation. These are signs of internal bleeding and should not be managed at home.
