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.

Hard to tell. But if it has been present for 3 days and not getting better, it is only prudent for you to consult your doctor about this issue especially if you have been to a less developed country within the past 2 weeks. Read more...

Maybe/not. Any allergy testing has its limitations. Both skin or blood testing can miss or over diagnose food allergies. They would also miss food sensitivities that are not based on allergies. They can be a guide on things to avoid, but sometimes a food diary & keeping track of what seems to aggravate symptoms will do more good. Read more...

I have allergist-diagnosed food allergies. Now I'm reacting to ham lunch meat (gas/diarrhea/itchy palate). Could it be a preservative allergy?

Ham allergy possible. It is important to know if you live in an area in the south and if you have been bitten by many ticks. The type of reaction you describe is typical of the early allergic reactions to Alpha galactose meat allergy. Intestinal cramping and diarrhea can happen 3-6 hours after eating mammalian meats. These can be variable at first with you reacting only after eating large amounts of the meat. 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?

Too complex to... address in this format. You've got some chronic issues and then what sounds like some more acute issues. First the temp of 99.6 is not a fever. Your chronic GI issues could be contributing to the newer symptoms. The best approach is to see the doctor that knows your history best so that they can address your newer symptoms to see if they are related. No way that can be done here in 400 letters. Read more...
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...

Wake up with nausea and stomach ache. Throw up and have diarrhea. No other symptoms. Pregncy imposs. Food allergy? Virus? Reaction to birth control?

Gastroenteritis. Either reaction to something in your food (toxins produced by staph, bacillus cereus, clostridium perfringens, etc.), or a viral etiology. In any event this should clear up within 3-5 days under most circumstances. If this recurs repeatedly you should see a GI doctor. Good luck. Read more...
