The most common ways to introduce either of these infections is through unclean water sources or poor hygiene. ...Read more

I am not sure: At all mainly since you are so young. Your complaint is usually the case of motility namely gastric emptying problems. Other option is infestation with a single cell parasite giardia lamblia but this goes with diarrhea you do not mention. I suggest see a GI specialist to check your stomach emptying. If that would be confirmed, blood test r/o an auto immune condition is in place. ...Read more

Everytime i eat eggs i get a sore stomach and burp heaps and it really smells horrible. Am i allergic or is this another problem?

Consider allergy?: Perhaps there can be some type of allergy you have with eggs? My suggestion would be to keep a food diary of everything you eat along with how you feel after those meals. See if there is a correlation with eggs and your symptoms. You may find it could be something else you are eating as well! ...Read more

I stay away from eggs, leafy greens, milk + any else that can cause rotten egg/methane smelling gas. Yet my gas smells like rotten egg/methane. Why?

Bacteria: in your intestinal tract break down food and produce methane and hydrogen sulfide causing the odor. Improve the health of your gut bacteria by eating probiotic foods such as yogurt, sauerkraut, kimchee, or aged cheeses. You can also take probiotic supplements.
