I think maybe he/she means "spastic" by "prelastic"?
Assuming you meant you have a lot of gas and diarrhea it could be lactose intolerance or possibly something like Celiac disease. There are tests for both. If you are not a (Northern) European caucasian and you have digestive problems it is probably best to assume that you are lactose intolerant and avoid all milk products. Only a small fraction of people can eat as much lactose as they want as adults, for everybody else it acts as a laxative, with the extent varying a lot from individual to individual. If you are lactose intolerant you are likely also to have similar symptoms if you eat sorbitol (found in diet gum, for instance) or some other (for you) indigestible disaccharides (sugars like lactose made up of two smaller sugars stuck together).
There are a lot of other possibilities though. It would help to know where you live, your ethnic background, your current age, what you eat, and any other health problems you might have.
Also writing so that we can understand you would help.
Welcome to the gastroenterology community! I don't understand what "talking strong" is and I have never heard of "prelastic of the bowels" before. Are you constipated or do you have diarrhea?
