Most stomach ulcers heal completely within six to twelve weeks with the right treatment, and the single most important step is identifying what caused the ulcer in the first place. The two major culprits are a bacterial infection called H. pylori and regular use of pain relievers like ibuprofen or aspirin. Treating the cause, not just the symptoms, is what makes ulcers go away and stay away.
Find Out What’s Causing Your Ulcer
An ulcer that keeps getting treated with antacids but never gets properly diagnosed tends to come back. The most common cause is H. pylori, a bacterium that burrows into the stomach lining and weakens its protective mucus layer. The second most common cause is frequent use of NSAIDs (nonsteroidal anti-inflammatory drugs) like ibuprofen, naproxen, or aspirin, which reduce the stomach’s ability to shield itself from its own acid.
Testing for H. pylori is simple and noninvasive. A urea breath test is the most accurate option, correctly identifying the infection about 94% of the time. Stool antigen tests and blood antibody tests are also available, though slightly less precise. If your doctor suspects complications or wants to see the ulcer directly, they may recommend an endoscopy, where a thin camera is passed down your throat to examine the stomach lining. But for most people, a breath test or stool test is enough to get started.
Treating an H. pylori Infection
If H. pylori is the cause, you’ll need a combination of antibiotics and an acid-suppressing medication taken for 14 days. The current recommended approach from the American College of Gastroenterology is a four-drug regimen: an acid suppressor taken twice daily, two different antibiotics taken multiple times per day, and a bismuth compound (the active ingredient in Pepto-Bismol) taken four times daily. This combination attacks the bacteria from multiple angles while lowering stomach acid to let the ulcer heal.
An older three-drug regimen using clarithromycin was once standard, but guidelines now recommend against it unless lab testing confirms the bacteria are sensitive to that specific antibiotic. Resistance to clarithromycin has become common enough that the newer four-drug protocol works more reliably for most people. Finishing the entire 14-day course matters. Stopping early because you feel better increases the chance the infection survives and the ulcer returns.
Ulcers Caused by Pain Relievers
If your ulcer is tied to NSAID use, the most effective treatment is stopping the drug. That alone, combined with an acid-reducing medication for several weeks, allows most ulcers to heal. If you can’t stop taking NSAIDs because of a condition like arthritis, your doctor may prescribe a protective medication that helps the stomach lining defend itself against acid damage. These drugs work by stimulating mucus production and reducing the amount of acid the stomach generates.
Switching to a different type of pain reliever, like acetaminophen, is often the simplest long-term fix. Acetaminophen doesn’t affect the stomach lining the way NSAIDs do. If you must stay on an NSAID or aspirin for heart protection, taking it with food and using the lowest effective dose reduces the ongoing risk.
How Long Healing Takes
Duodenal ulcers, which form in the first part of the small intestine just past the stomach, typically heal in about six weeks. Gastric ulcers, located in the stomach itself, are slower and can take two to three months to fully close. These timelines assume you’re on appropriate treatment and have addressed the underlying cause.
During this window, acid-suppressing medications do the heavy lifting. Proton pump inhibitors (PPIs) are the most commonly prescribed class. They dramatically reduce acid production, giving the damaged tissue a chance to rebuild. You’ll likely take one for four to eight weeks depending on the ulcer’s location and severity. Symptoms like burning pain and nausea often improve within the first week or two, but the ulcer itself needs the full course to heal underneath.
What Actually Helps (and What Doesn’t Matter)
One of the most persistent myths about ulcers is that spicy food causes them or prevents healing. The evidence tells a more nuanced story. Capsaicin, the compound that makes chili peppers hot, has actually been shown to promote stomach lining repair and even inhibit H. pylori growth at normal dietary amounts. At very high doses it can irritate damaged tissue, but eating moderately spicy food won’t slow your recovery. If spicy meals make your symptoms feel worse in the moment, it’s fine to cut back for comfort, but you’re not sabotaging the healing process.
Alcohol and smoking, on the other hand, do interfere with healing. Alcohol irritates the stomach lining directly, and smoking reduces blood flow to the gut and increases acid secretion. Cutting both out during the healing period makes a measurable difference. Coffee and caffeine don’t cause ulcers, but they stimulate acid production, so reducing intake can ease discomfort while you recover.
Some people turn to honey, particularly manuka honey, as a natural remedy. Animal studies have shown that honey can reduce ulcer severity and promote tissue repair, likely through its anti-inflammatory and antimicrobial properties. While that’s promising, honey works best as a complement to standard treatment, not a replacement. No natural remedy alone can eradicate an H. pylori infection or undo the damage from chronic NSAID use.
Protective Medications for Stubborn Cases
For ulcers that are slow to respond or for people who face ongoing risk factors, doctors sometimes add a mucosal protectant. Sucralfate is one example. Rather than suppressing acid, it works by boosting the stomach’s mucus production, creating a physical barrier over the ulcer site. This mechanism is independent of the chemical pathways that NSAIDs disrupt, which makes it useful when pain relievers are part of the picture. It’s typically taken on an empty stomach so it can coat the ulcer directly.
Warning Signs That Need Immediate Attention
Most ulcers heal without complications, but a small percentage bleed heavily or perforate (break through the stomach wall entirely). You should treat the following as emergencies:
- Sudden, severe abdominal pain that comes on sharply and doesn’t let up, especially if your abdomen feels rigid or hard to the touch
- Vomiting blood, which may look bright red or resemble dark coffee grounds
- Dark, tarry, or maroon-colored stools, a sign of bleeding in the digestive tract
- Signs of shock, including fainting, confusion, or heavy sweating
A perforated ulcer requires surgery. Severe bleeding that can’t be controlled through endoscopy also requires surgical repair. These complications are uncommon with proper treatment, but they’re the reason ulcers shouldn’t be ignored or managed indefinitely with over-the-counter antacids alone. Getting a proper diagnosis and treating the root cause is what separates an ulcer that heals for good from one that keeps coming back.
