if you are eating a lot (same/more than usual) but are losing weight then i would suggest you go to a doctor. it might be worms, but it might be something else altogether - something serious that you need to catch early on.

only your doc will know the right questions to ask to determine what explanations you could be looking at. when i started losing weight, i thought it was great and didnt say anything - but it quickly turned into a nightmare and i wish i had gone to my doc earlier.
