why when i eat cereal with whole milk give me diarrhea

There could be a few potential reasons for this:

1. Lactose intolerance: Whole milk contains lactose, a type of sugar that some individuals cannot digest properly. This can lead to symptoms like diarrhea, bloating, and gas.

2. Milk allergy: It is possible that you have an allergy to milk proteins, which can cause gastrointestinal symptoms like diarrhea when consumed.

3. Irritable bowel syndrome (IBS): Some people with IBS may experience symptoms like diarrhea when consuming certain foods, including dairy products.

4. Food sensitivity: You may have an individual sensitivity to something in the cereal or milk that is triggering a digestive response, resulting in diarrhea.

If you suspect that milk is causing your diarrhea, it's best to consult a medical professional for proper diagnosis and guidance. They may recommend avoiding whole milk or trying lactose-free alternatives to see if your symptoms improve.
