Digestive Symptoms

When your digestive system comes into contact with something that your immune system views as a threat, it quickly responds by releasing a chemical called histamine. The release of histamine, along with other substances in your body, is what causes a reaction. This reaction is not age related; it can occur suddenly, and can cause uncomfortable digestive symptoms. An allergy can cause digestive problems like stomach pain, diarrhea and vomiting in adults as well as in children.1-3

If you think you or someone you love has a food allergy, do not try to manage the problem on your own. You could be unnecessarily removing foods from your or their diet. Talk to your healthcare professional about a blood test to find out what could be the possible causes of your symptoms.

Common foods that cause digestive problems

Digestive/gastrointestinal problems are closely tied to what you eat, but food allergies aren’t the only cause. Lactose intolerance and celiac disease can be confused with a food allergy because they all have such similar symptoms.4,5 You may feel that you’re allergic to food because you had a bad reaction after eating, but you may not actually have an allergy. In fact, people self-report having food allergies six times more than they actually have them.6

Learn more below about the various foods that frequently cause digestive problems.

Soy

 

You may be taking antacids or avoiding the foods you think could have caused a reaction. Many people are so used to living with—and sometimes embarrassed by—their uncomfortable digestive problems that they never consider asking for help. But learning what could be causing your symptoms may also help you avoid more serious problems in the future.


And food allergies aren’t the only concern—there are long-term complications from undiagnosed gluten-related disorders too. Untreated celiac disease can lead to serious issues including intestinal cancers, iron deficiency anemia, early onset osteoporosis and infertility.
