I just returned from a 2-week trip to the Philippines. I was very careful and only drank service water or filtered water. But something I ate caused diarrhea. I ve had it for a week now. Symptoms are abdominal pains (not bad now, but were very bad at first), several loose stools a day, and weakness (don t know if it s still jet lag or from the diarrhea). I thought it was better and just ate a regular small meal, and it started again. Should I take Imodium or go to the doctor? Could it be dangerous? I am in very good health, but 69 years old. Thank you for your answer. Lauri
