wikiHow Foods to Avoid to Help with a Stomach Ulcer If you have a stomach ulcer, it's important to work closely with a healthcare professional to develop a personalized treatment plan. While there is no one-size-fits-all list of foods to avoid for stomach ulcers, certain foods and beverages can potentially irritate the stomach lining and worsen symptoms. Here are some foods and beverages that are commonly advised to be avoided or limited when managing a stomach ulcer: Spicy foods: Hot peppers, chili powder, and other spicy seasonings can irritate the stomach lining. Citrus fruits: Oranges, lemons, grapefruits, and their juices are acidic and may cause discomfort. Tomato-based products: Tomato sauce, tomato juice, and ketchup can be irritating due to their high acidity. Coffee: Contains caffeine and may increase stomach acid production, potentially aggravating symptoms. Carbonated beverages: The carbonation can contribute to bloating and increased gastric pressure. Alcohol: Can irritate the stomach lining and increase acid production. Peppermint: May relax the lower esophageal sphincter, allowing acid to reflux into the stomach. Fried and fatty foods: High-fat foods can slow down digestion and increase the risk of acid reflux. Processed meats: Deli meats and other processed meats often contain preservatives that can irritate the stomach lining. Onions: Raw onions can be difficult to digest and may cause discomfort. Garlic: Raw garlic can have a similar effect as onions and may increase acid production. Spicy condiments: Hot sauces, spicy mustards, and other condiments can worsen symptoms. Chocolate: Contains caffeine and may relax the lower esophageal sphincter, leading to acid reflux. High-sugar foods: Excessive sugar intake can disrupt the balance of gut bacteria and potentially worsen symptoms. High-sodium foods: Excess sodium can increase water retention and contribute to bloating. Artificial sweeteners: Some artificial sweeteners, such as aspartame, may cause digestive discomfort in some individuals. Acidic foods: Sour candies, vinegar, and pickled foods can irritate the stomach lining. High-fiber foods: While fiber is generally beneficial, some high-fiber foods like bran cereals and certain raw vegetables can be difficult to digest and aggravate symptoms. Mint: Peppermint candies, chewing gum, and mint-flavored products may relax the lower esophageal sphincter. Processed snacks: Chips, pretzels, and other processed snacks may contain additives and preservatives that can irritate the stomach. It's important to note that individual tolerances may vary, and some people may tolerate certain foods better than others. Working with a healthcare professional or registered dietitian can help you identify your specific trigger foods and develop a personalized diet plan to manage your stomach ulcer. Page
