Stomach Ulcers and Your Immune System — November 2023 Archive
In November 2023 we published a practical post about how the immune system affects stomach ulcers. I break down how infections, medicines, and inflammation work together to cause ulcers, and give clear everyday steps you can use to prevent and treat them.
Why your immune system matters
Your stomach lining has a thin mucus layer and immune cells that protect it. When H. pylori bacteria invades, or when you take NSAIDs often, that protection weakens. Your immune system reacts to the damage and to the bacteria. That reaction causes inflammation, and inflammation can make the lining more likely to break down into an ulcer.
People differ in their immune responses. Some carry H. pylori without symptoms for years. Others get ulcers quickly because their immune response is stronger or because they have other health problems that raise inflammation. The post explains that treating the cause and calming inflammation together helps healing.
Simple, effective steps to protect your gut
First, avoid long-term NSAID use unless a doctor says it’s necessary. These drugs reduce protective mucus and raise ulcer risk. Second, if you have persistent stomach pain, ask for an H. pylori test — antibiotics plus acid-reducing medicine often cure the infection and let ulcers heal. Third, stop smoking and cut back on alcohol. Both slow healing and increase complications.
Manage stress in practical ways: get enough sleep, build short walks into your day, try breathing or brief meditation, and keep regular mealtimes. Stress doesn’t directly cause ulcers, but it changes immune function and pain perception, which makes problems worse.
Diet matters too. The post suggests avoiding foods and drinks that trigger your symptoms, like very spicy dishes and large coffee loads. Add probiotic foods such as yogurt or fermented vegetables to support gut balance. Small, consistent changes often help more than big one-off efforts.
If you must take drugs that raise ulcer risk, ask about protective options like proton pump inhibitors or misoprostol when appropriate. Always follow up with your doctor if symptoms change. Warning signs include severe belly pain, black or tarry stools, vomiting blood, fainting, or sudden weakness — those need urgent care.
The post included a short checklist you can use at home, plus a real patient example showing how testing for H. pylori, stopping daily ibuprofen, and a short antibiotic course led to quick recovery. That mix of testing, treatment, and lifestyle change is the simplest path to fewer ulcers and fewer recurrences.
For people tracking their gut health, the November post is a useful, no-nonsense guide to what to test for, what to avoid, and when to see a doctor.
If you have recurring ulcers or complications, ask for specialist care. A gastroenterologist can order an endoscopy to look directly at the lining and rule out other problems. They can also guide longer-term care, check for medication interactions, and plan follow-up testing after treatment. Keep a simple symptom diary—note foods, meds, stress, and pain times. That diary often helps clinicians spot patterns and choose the best treatment fast. Share the diary at appointments to speed up correct treatment quickly.
