I get yellow watery explosive diarrhoea if i go for a long time and then eat all of a sudden. why am i getting this yellow diarrhoea?

Episodic urgent bm's: Lots of Rx options but cure depends on cause: "plugging up" diarrhea will not cure an infection, fix an inflammatory process, improve an ischemic gut, or correct a functional issue. Medical evaluation is recommended appropriate to the duration of your symptoms, associations (bleeding, weight loss, pain, vomiting), as well as your other medical co-morbidities (including anxiety as listed).
