I am a 20-year-old female. I am taking a vegetarian diet and I am worried about my problem. I feel bloated constantly. I pass large stools and I eat gluten occasionally. I feel bloated after waking up and after falling asleep. What is the cause? I have been dealing with this problem for a year. I was taking a vegan diet and I stopped it. After that, I started taking a vegetarian diet. I am lactose intolerant and I eat gluten occasionally.
