Can diarrhea be caused by food allergy?

Can diarrhea be caused by food allergy?

Yes: Especially in children. Many food allergies can be outgrown with maturing immune and gastrointestinal systems. Most patients with diarrhea don't have a true food allergy (involving immune system response) as the cause. Diarrheas may be due to digestive issues (e.g. Celiac sprue), intolerance, malabsorption (e.G lactose), infection (bacterial, viral, parasitic), inflammatory, irritable bowel. ...Read more

Why do I get diarrhea after eating pizza? I have no food allergy that I'm aware of and I eat bread and other dairy products all the time with no probs

Lactose Intolerance: While you note you can eat other dairy products without a problem pizza cheeses like mozzarella are fresher cheeses with more lactose present. Try taking some OTC Lactase the next time you eat pizza. If this solves your problem, you have your answer it's lactose intolerance...if not see an allergist for further evaluation. ...Read more

I have a mystery food allergy that leads to severe bloating and diarrhea. I usually take an antihistamine & am fine. Had a bad reaction, felt faint, bright red blood in stool. Should I be worried?

I have a mystery food allergy that leads to severe bloating and diarrhea. I usually take an antihistamine & am fine. Had a bad reaction, felt faint, bright red blood in stool. Should I be worried?

Start a food diary: Though it is time consuming, you may wish to start a food diary. Begin with simple foods (only!) to which you KNOW you don’t react. Then add a new food ever 3 or 4 days and watch for an allergic reaction. Note on paper or smart phone (there’s a food allergy app for this) no, mild, or bad reaction. This takes time and diligence, but you should be able to find out which foods to avoid. ...Read more

Fever of 99.6 for 7 days, left lower abdomen pain, bloated, occasional bleeding in bowel, diarrhea, food allergies, throwing up clean colonoscopy. Help?

Fever of 99.6 for 7 days, left lower abdomen pain, bloated, occasional bleeding in bowel, diarrhea, food allergies, throwing up clean colonoscopy. Help?

Get 2nd opinion: It almost sounds like diverticulitis which may not be detected by a colonoscopy. On the other hand, throwing up is not part of the symptoms unless you have a systemic infection which does occurs in diverticulitis. The counterpoint is that diverticulitis occurs usually in a much older age Food allergy is not associated with a fever. Suggest a consult @ an university center or with another GI. ...Read more

Gastroenteritis: Either reaction to something in your food (toxins produced by staph, bacillus cereus, clostridium perfringens, etc.), or a viral etiology.

Are food allergies linked to Crohn's or any other disease of long-term intestinal damage? Have many food allergies w/ intestinal symptoms.

Do food allergies last a lifetime, or do they eventually go away?

Go away in kids: You are 37 years old. Although I have seen fish allergy resolve after 20 years or so, for most adults food allergies do not go away. In children & infants most dairy, egg, wheat, soy & corn allergy resolves in a few years. For example, for dairy we see at least 80% resolution in 10-15 years. Even peanut & tree nut allergy resolves spontaneously in 20-25% of kids. ...Read more

Multiple food allergies. Last tested 2 years ago. Could I lose some food and allergies & gain new ones? 36f. Test again?

See an Allergist/Imm: First, food allergy testing can be falsely positive, so without knowing more of your history, it's hard to know if some of the tests were positive without a true allergy to that food. It can certainly happen that one may "outgrow" an allergy to one food and develop an allergy to a new food, but it is not frequent. If you haven't already done so, you should see an allergist/immunologist. ...Read more
