How Long Does a Stomach Ulcer Take to Heal?
If you have just been told you have an ulcer, one of your first questions is probably how long it will take to feel better. The answer depends mostly on one thing: whether the cause is identified and treated.
The typical timeline
- Pain relief: many people notice improvement within days of starting acid-reducing medicine.
- Healing of the ulcer: most uncomplicated ulcers heal within four to eight weeks of treatment. Larger stomach (gastric) ulcers can take longer than duodenal ulcers.
- H. pylori treatment: the antibiotic course usually lasts 10 to 14 days, followed by a retest at least four weeks later.
Feeling better is not the same as being healed. Pain often settles well before the ulcer has fully closed, which is why stopping treatment early is a common mistake.
What speeds healing
- Treating the cause: clearing H. pylori or stopping or reducing anti-inflammatory painkillers, with your doctor's guidance
- Taking acid-reducing medicine exactly as prescribed, often 30 to 60 minutes before a meal
- Stopping smoking
- Avoiding alcohol during treatment
- Regular, gentle meals
What slows healing
- Continuing to take ibuprofen, aspirin, naproxen or similar painkillers without medical advice
- Smoking
- Missing doses of antibiotics or acid blockers
- Untreated H. pylori, which makes ulcers very likely to return
When your doctor may check again
For some stomach ulcers, doctors arrange a follow-up endoscopy to confirm complete healing and to make sure there is nothing else going on. If H. pylori was treated, a breath or stool test confirms whether it has gone.
When to seek help sooner
Contact a doctor promptly if pain gets worse instead of better, or if you notice black stools, vomiting blood or sudden severe pain.
Key takeaway
Most ulcers heal in weeks, not years. The people who struggle for a long time are usually those whose cause was never confirmed or whose treatment was not completed. Know your cause, finish your treatment, and confirm the result.
