Understanding the Connection Between Gastritis and Food Intolerance

Gastritis is a condition that affects the stomach lining, often accompanied by symptoms such as abdominal pain, nausea, vomiting, and loss of appetite. Other common digestive symptoms like bloating, diarrhea, and stomach cramps are caused by food intolerance, an adverse reaction to certain food items. 

While the exact connection between gastritis and food intolerance is yet to be fully understood, it is believed that food intolerances can aggravate the symptoms of gastritis.

Understanding Gastritis

Gastritis is an inflammation of the stomach lining, often caused by infection or irritation of the stomach’s mucous membrane. It can lead to ulcers and other complications in the gastrointestinal tract.

Common causes include infection, irritants such as alcohol or certain medications, or a reaction to an allergen. Typical symptoms include pain in the upper abdomen, nausea and vomiting, indigestion, and a feeling of fullness.

There are several types of gastritis, including:

  • Erosive gastritis: causes erosion of the stomach lining
  • Chronic gastritis: ongoing inflammation
  • Acute gastritis: a sudden flare-up

Gastritis can be diagnosed with a physical exam and tests such as blood tests, endoscopy, biopsy, X-ray, and/or ultrasound. Treatment for gastritis depends on the cause and can include antacids, antibiotics, anti-inflammatories, or immunosuppressants.

Food Intolerance

Unlike food allergies, which are triggered by the immune system, food intolerance is caused by a digestive system reaction. It is not necessarily life-threatening but can cause uncomfortable symptoms such as abdominal pain, diarrhea, bloating, and gas.

There are several types of food intolerance, including lactose intolerance, histamine intolerance, fructose intolerance, gluten intolerance, and sulfite sensitivity. Each type of food intolerance has its own set of signs and symptoms.

The exact cause of food intolerance is often unknown. However, some potential causes include sensitivity to food additives, enzyme deficiencies, digestive disorders, and metabolic issues.

Symptoms of food intolerance vary depending on the type of food and the individual’s sensitivity level. Common symptoms include abdominal pain, bloating, nausea, vomiting, diarrhea, headaches, fatigue, skin reactions, and respiratory symptoms.

Food intolerance can be diagnosed with a variety of tests. These include skin prick tests, blood tests, food challenge tests, breath tests, and elimination diets. In some cases, a doctor may recommend an elimination diet in which all suspect foods are removed from the diet for some time to see if symptoms improve.

The Connection between Gastritis and Food Intolerance

Gastritis is an inflammation of the lining of the stomach, and it is often associated with food intolerance. Food intolerance is a condition in which the body is unable to digest certain types of food. These intolerances can be caused by a variety of factors, such as food allergies, enzyme deficiencies, or intolerances to certain components in the food. This can cause an individual to experience a wide range of digestive issues, such as bloating, cramps, nausea, and vomiting. When these symptoms become chronic or prolonged, they can lead to the development of gastritis.

When individuals eat foods they are intolerant to, it triggers an immune response in the gut. This leads to increased inflammation, which can then cause damage to the stomach lining and lead to gastritis. Additionally, certain foods may trigger or exacerbate certain digestive issues that can further contribute to gastritis. For example, acidic foods such as tomatoes and citrus fruits can irritate the stomach and worsen existing gastritis symptoms.

Food intolerance can also play a role in exacerbating existing gastritis symptoms. Foods that are high in fat and processed ingredients can be difficult for the body to digest, further irritating the stomach lining and leading to further inflammation. Additionally, eating large meals or eating too quickly can lead to increased gastritis symptoms. Individuals with gastritis need to pay attention to their dietary habits and make sure to monitor any potential reactions they may have to certain foods.

Managing Gastritis and Food Intolerance

These changes include reducing stress, avoiding smoking and alcohol consumption, eating small and frequent meals, and drinking plenty of fluids. Additionally, getting enough rest and exercise regularly is important to keep your body healthy overall.

People with gastritis should avoid certain foods and drinks known to trigger symptoms, such as spicy foods, fatty or fried foods, processed foods, alcohol, caffeine, and acidic foods like citrus fruits. Eating smaller portions more often can also help reduce the risk of triggering a flare-up.

Some strategies can be employed to help manage the symptoms of those with food intolerance. These include tracking what triggers the symptoms and avoiding them in the future, being mindful of portion sizes, and focusing on eating healthy and balanced meals, as well as taking probiotics or digestive enzymes to help support gut health.

Eating a healthy and balanced diet is key for managing gastritis and food intolerance. This includes incorporating a variety of fruits, vegetables, whole grains, lean proteins, and low-fat dairy products into your daily meals. Drinking plenty of water throughout the day and limiting the intake of sugary drinks and processed foods are also important to support a healthy digestive system. By following these steps, it is possible to reduce symptoms associated with both gastritis and food intolerance.


Gastritis and food intolerance are closely related, as the symptoms of gastritis can be triggered or worsened by food intolerance. The key takeaway is to identify which foods cause gastritis flare-ups and adjust one’s diet accordingly. This includes cutting out problematic foods and replacing them with nutritious alternatives. A balanced diet is essential for overall health, including gut health.

Additionally, paying attention to portion sizes and eating meals slowly may help ease digestive discomfort. Regular physical activity helps relieve stress, which can worsen gastritis symptoms. Keeping hydrated throughout the day may help improve digestion. Last but not least, reducing or avoiding the use of alcohol and caffeine may help decrease inflammation in the stomach lining.

It is also important to seek medical advice if experiencing any symptoms associated with gastritis or food intolerance. With proper management and lifestyle changes, it is possible to reduce or even eliminate gastritis symptoms.
