Most stomach ulcers heal within two to three months with the right combination of acid-reducing medication and, when needed, antibiotics. The key to getting rid of a stomach ulcer is identifying what caused it, then targeting that cause directly. The two most common culprits are a bacterial infection called H. pylori and regular use of pain relievers like ibuprofen or naproxen. Treatment looks different depending on which one is behind your ulcer.
Find Out What Caused Your Ulcer
Before any treatment plan makes sense, you need to know the root cause. Your doctor will typically test for H. pylori, a bacterium that burrows into the stomach lining and triggers chronic inflammation. About half of all ulcer cases trace back to this infection. The other major cause is frequent use of NSAIDs (nonsteroidal anti-inflammatory drugs), the category that includes ibuprofen, aspirin, and naproxen. These medications weaken the protective mucus layer in your stomach, leaving the tissue exposed to acid.
In some cases, both factors are present at the same time. Current clinical guidelines recommend testing every ulcer patient for H. pylori regardless of whether NSAID use seems like the obvious explanation, because treating the infection dramatically improves healing outcomes.
Treating an H. pylori Infection
If H. pylori is detected, you’ll need a combination of antibiotics and acid-suppressing medication, typically taken for 14 days. The current recommended approach from the American College of Gastroenterology pairs two antibiotics with bismuth (the active ingredient in Pepto-Bismol) and an acid-reducing drug taken twice daily. This combination attacks the bacteria from multiple angles while lowering stomach acid so the ulcer can heal.
Older antibiotic combinations that relied on clarithromycin have fallen out of favor because resistance to that antibiotic has become widespread. The updated guidelines specifically recommend against using clarithromycin unless lab testing has confirmed the bacteria in your stomach are still sensitive to it. If your doctor prescribes a regimen, finishing every dose matters. Stopping early is one of the most common reasons the infection survives and the ulcer comes back.
Treating Ulcers From Pain Relievers
If your ulcer developed from NSAID use, the first step is stopping the medication if possible. For many people, switching to a different type of pain management is enough to let healing begin once acid-suppressing treatment starts. Proton pump inhibitors (PPIs) are the preferred choice here. Clinical trials have consistently shown that ulcers heal faster with PPIs than with older acid-reducers, protective coating agents, or other alternatives.
The situation gets more complicated if you take low-dose aspirin for heart protection. Stopping aspirin raises cardiovascular risk, so the decision involves weighing that against the severity of the ulcer. In many cases, aspirin can be restarted within three to five days of beginning PPI therapy. If you’re on aspirin for a heart condition and develop ulcer symptoms, this is a conversation to have with your doctor rather than a decision to make on your own.
How Acid-Reducing Medications Work
Your stomach produces acid constantly, and two main classes of drugs dial that production down. PPIs are the more powerful option. They shut down the acid pumps in your stomach lining directly, creating an environment where damaged tissue can rebuild. These are typically used for the active healing phase.
H2 blockers work differently. After you eat, your body releases a chemical messenger called histamine that binds to receptors on stomach cells and triggers acid production. H2 blockers occupy those receptors first, preventing the signal from getting through. They’re effective but less potent than PPIs, which is why PPIs are generally the first choice for active ulcers. H2 blockers sometimes play a role in maintenance therapy after the ulcer has healed.
Most people take acid-reducing medication for two to six weeks to support healing and relieve pain. Gastric ulcers (in the stomach itself) tend to heal more slowly than duodenal ulcers (in the upper part of the small intestine). Expect a full recovery timeline of up to two to three months for stomach ulcers, compared to roughly six weeks for duodenal ulcers.
Dietary and Lifestyle Changes That Help
No specific diet cures an ulcer, but certain habits can support faster healing and reduce the chance of recurrence. Smoking is one of the clearest risk factors. Epidemiological data show that cigarette smoking increases both the rate of new ulcers and the rate of relapse, and it slows healing while an ulcer is active. Quitting during treatment gives medication the best chance of working.
Alcohol compounds the problem, especially in combination with smoking. Animal studies confirm that alcohol-induced stomach damage is significantly worse in the presence of cigarette smoke, and human data point to the same pattern. Cutting out both during the healing window is one of the most impactful things you can do.
On the food side, some evidence supports specific additions to your diet. A clinical trial found that patients who added two grams of ginger daily (in supplement form) to their standard ulcer treatment saw greater reduction in ulcer size and H. pylori presence compared to those on medication alone. The anti-inflammatory compounds in ginger, particularly gingerols, appear to reduce inflammatory signaling and support antioxidant activity in the stomach lining. This was used alongside standard treatment, not as a replacement.
Zinc-carnosine, a supplement that pairs zinc with the amino acid L-carnosine, has also shown consistent results. At a dose of 75 mg twice daily, it supports the stomach’s natural protective mechanisms through anti-inflammatory and antioxidant effects. Research shows it speeds healing regardless of the ulcer’s underlying cause and works well alongside PPIs or antibiotic therapy.
What to Avoid During Healing
Beyond quitting smoking and alcohol, pay attention to anything that directly irritates your stomach lining. Coffee (including decaf) stimulates acid production. Spicy foods don’t cause ulcers, but they can aggravate an open one and make symptoms worse. The same goes for acidic foods like tomatoes and citrus.
If you’ve been using over-the-counter NSAIDs regularly for headaches, back pain, or joint issues, find an alternative during treatment. Acetaminophen (Tylenol) doesn’t carry the same ulcer risk because it works through a different mechanism that doesn’t affect the stomach lining.
Warning Signs That Need Immediate Attention
Most ulcers heal without complications, but some progress to dangerous territory. An ulcer can erode into a blood vessel, causing internal bleeding, or eat completely through the stomach wall, creating a perforation that allows bacteria to spill into the abdominal cavity.
The symptoms to watch for are specific: vomiting blood (which may look red or resemble dark coffee grounds), stools that are black, tarry, or contain dark blood, and sudden dizziness or fainting. These indicate active bleeding and require emergency care. A perforation typically causes sudden, severe abdominal pain that doesn’t let up. Any of these symptoms mean you should get to an emergency room, not wait for a scheduled appointment.
