Stomach ulcers are open sores that develop in the lining of the stomach, causing symptoms such as indigestion, acid reflux, heartburn, nausea, vomiting, and bloating. While food choices do not cause stomach ulcers, certain foods may help against ulcer-causing bacteria. For instance, a diet rich in fibre can lower the risk of developing an ulcer, while probiotics can help restore the natural balance of bacteria in the gut. Additionally, people with stomach ulcers often have diets low in antioxidants, so consuming foods like blueberries, cherries, and bell peppers may help activate the immune system and fight infection.

Stomach ulcers are open sores that develop within the lining of the stomach. They are caused by the Helicobacter pylori (H. pylori) bacterial infection, as well as the chronic use of over-the-counter non-steroidal anti-inflammatory drugs such as aspirin and ibuprofen. While dietary choices do not cause ulcers or make them worse, certain foods may contain ingredients that fight against ulcer-causing bacteria.
An ulcer diet includes foods like berries, eggs, lean meats, and whole grains, which may help limit symptoms. Berries, such as blueberries, blackberries, and cherries, are packed with antioxidants, which may be beneficial if your ulcer is caused by an H. pylori infection. Broccoli also contains sulforaphane, a compound that exhibits anti-H. pylori activity. Leafy greens such as kale and spinach contain calcium and B vitamins, which are packed with vitamins and antioxidants that are especially good for overall health and healing.
Eggs are a great source of low-fat protein, as are skinless poultry, lean beef, and fatty fish like salmon, mackerel, and sardines. Fatty fish provide omega-3 fatty acids, which can reduce inflammation and may help prevent another ulcer. Whole grains are also a good addition to an ulcer diet, as they are bland and easily digestible, making up the majority of what you eat.
It is also important to exclude certain foods from your diet, such as fried foods, alcohol, and large amounts of added fats, as these can increase stomach acid and trigger reflux. Spicy foods may irritate your ulcer, so limiting these can help reduce symptoms.

Foods to avoid: alcohol, fried foods, fatty foods, spicy foods, chocolate, caffeine, etc
While there is no specific diet for people with stomach ulcers, certain foods may help fight the cause of your stomach ulcer.
Alcohol
Alcohol is a stomach irritant and will delay healing. Avoid wine, beer, and spirits.
Fried foods
Fried foods take longer to digest and can aggravate stomach ulcers. Fried foods like bacon or sausage are best avoided.
Fatty foods
Fat can increase stomach acid and trigger reflux. A high-fat diet can inhibit the gastric ulcer healing process.
Spicy foods
Spicy foods don't cause ulcers, but they may irritate your ulcer. Chili peppers, horseradish, black pepper, and sauces with these ingredients can be problematic.
Citrus fruits
Citrus fruits such as lemons, oranges, and grapefruits are acidic, and they can cause pain if you have an ulcer. However, they are high in vitamin C and flavonoids, and some studies show they reduce inflammation and inhibit the spread of H. pylori, so they can be beneficial. Keep them in your diet if they don't cause discomfort.
Chocolate
Chocolate can increase stomach acid production and trigger reflux symptoms.
Caffeine
Coffee, tea, and caffeinated sodas can increase stomach acid production.

Probiotics: Lactobacillus, kombucha, and other beverages with probiotics can help restore gut bacteria
Probiotics are live microorganisms that are intended to have health benefits when consumed or applied to the body. They are often referred to as "good" bacteria and are essential for a thriving gut microbiome. Probiotics fight harmful microbes and support beneficial ones.
Lactobacillus is a genus of rod-shaped, gram-positive, non-spore-forming, facultative anaerobic bacteria of the phylum Firmicutes. Lactobacilli metabolize carbohydrates to produce lactic acid, which prevents the growth of putrefactive organisms. Lactobacilli have demonstrated efficacy in treating various conditions, including bacterial vaginosis, atopic dermatitis, and upper respiratory tract infections.
Kombucha is a fermented tea that contains organic acids and polyphenols, which exhibit antimicrobial properties and help regulate the immune system, respectively. It is also a source of B vitamins, which are essential for a healthy immune system. The enzymes and acids in kombucha can assist the liver in removing unwanted compounds from the body.
Beverages with probiotics, such as kombucha, can help restore gut bacteria and decrease bad bacteria. Probiotics may also be recommended to help restore the microbiome after a course of antibiotics, which is often necessary to treat stomach ulcers caused by H. pylori infections.
In addition to kombucha, other sources of probiotics include blackberries, broccoli, and fermented foods such as miso, sauerkraut, and kimchi.

Antibiotics: H. pylori infections, which cause most ulcers, are treated with antibiotics
Stomach ulcers are open sores that develop within the lining of the stomach. They are usually caused by an infection of Helicobacter pylori (H. pylori) bacteria or from taking anti-inflammatory medicines (NSAIDs) such as ibuprofen and aspirin.
H. pylori infections are caused by H. pylori germs that get into the stomach lining. The germs are passed from person to person through contact with saliva, vomit, or stool. They may also be spread through contaminated surfaces or tainted food or water. Risk factors for H. pylori infections include living in crowded conditions, lacking access to clean water, and living in a developing country.
H. pylori infections, which cause most ulcers, are treated with antibiotics. Initial treatment options include a 14-day bismuth-based quadruple therapy or rifabutin-based triple therapy. Triple therapy consists of a proton pump inhibitor (PPI) such as omeprazole or lansoprazole, plus clarithromycin or metronidazole. A ten-day quadruple therapy comprising low-dose rabeprazole, bismuth, amoxicillin, and tetracycline is also an effective and safe first-line treatment for populations with high antibiotic resistance.
In addition to antibiotics, it is recommended to incorporate foods rich in antioxidants into your diet, as they could help protect and activate your immune system and fight the H. pylori infection. Foods like blueberries, cherries, and bell peppers are packed with antioxidants, while leafy greens such as kale and spinach contain calcium and B vitamins. Broccoli contains sulforaphane, a compound that exhibits anti-H. pylori activity, and olive oil contains fatty acids that can help treat an H. pylori infection.

Acid reducers: Medication can help reduce stomach acid, creating an environment for healing
Stomach ulcers are open sores that develop within the lining of the stomach when stomach acid eats through the protective stomach lining. While food choices do not cause stomach ulcers or make them worse, certain foods can irritate ulcer sores and delay healing. Doctors recommend avoiding foods that cause pain or discomfort. Acidic foods like citrus fruits and tomatoes, for example, can cause a burning sensation in people with ulcers. Alcohol, coffee, tea, and caffeinated sodas can increase stomach acid production and trigger reflux symptoms. Fatty foods, fried foods, spicy foods, and chocolate should also be avoided as they can irritate ulcer sores and delay healing.
On the other hand, a diet rich in fiber can lower the risk of developing a stomach ulcer. Foods with fiber coat the lining of the stomach and reduce the damage that gastric acid would have on the stomach lining, thereby reducing ulcer formation. High-fiber foods include broccoli, leafy greens, berries, oatmeal, high-fiber cereals, and whole-grain breads. A diet high in vitamin A is also associated with a lower risk of ulcers, with sweet potatoes, carrots, squash, kale, spinach, broccoli, tomatoes, red bell peppers, cantaloupe, and mango being good sources of the vitamin.
In addition to dietary changes, medication can help reduce stomach acid, creating an environment for healing. Doctors may prescribe acid-reducing medications to treat stomach ulcers and allow the ulcers to heal. Proton pump inhibitors (PPIs) and H2 blockers are medications that can help reduce the amount of acid the stomach produces. Antibiotics may also be prescribed if the ulcer is caused by a bacterial infection, such as Helicobacter pylori (H. pylori). Acid blockers like famotidine (Pepcid) can provide fast relief from stomach ulcer symptoms.

Frequently asked questions
Stomach ulcers are open sores that develop in the lining of the stomach when stomach acid eats through the protective stomach lining. The main causes of stomach ulcers are Helicobacter pylori (H. pylori) bacterial infections, prolonged use of non-steroidal anti-inflammatory drugs (NSAIDs), and certain lifestyle factors such as smoking, excessive alcohol consumption, and an unhealthy diet.
Treatment for stomach ulcers depends on the underlying cause. If the ulcer is caused by H. pylori, a combination of antibiotics and proton pump inhibitors (PPIs) is usually prescribed to reduce stomach acid and fight the infection. For ulcers caused by prolonged NSAID use, consulting a doctor about alternative treatments or reducing NSAID usage may be advised.
While diet alone may not heal stomach ulcers, certain foods can help reduce symptoms and promote healing. High-fibre, unprocessed foods, and probiotics can help restore gut bacteria and reduce stomach acid. Antioxidant-rich foods like blueberries, cherries, leafy greens, and broccoli may also help fight H. pylori infections. It is recommended to avoid spicy foods, alcohol, fried foods, and acidic foods that can irritate ulcer sores and increase stomach acid.
Common symptoms of a stomach ulcer include burning stomach pain, indigestion, bloating, nausea, vomiting, and acid reflux. Some people may not experience any noticeable symptoms, while others may develop complications such as internal bleeding or perforation. If you suspect you have a stomach ulcer, it is important to consult a healthcare professional for diagnosis and treatment.
Dietary choices alone do not cause stomach ulcers, but certain foods can aggravate symptoms and delay healing. A balanced and nutritious diet, rich in fibre and antioxidants, may help lower the risk of developing stomach ulcers and relieve symptoms. Reducing processed foods, alcohol consumption, and smoking can also help prevent and manage stomach ulcers.
