Hello, I have a question about my colon . Recently i have been farting a lot lately, more than ever, and it smells just terrible. I have been doing some research online and have found that this might be the cause of lactose intolerance . I have cut out as much dairy as much as i can out of my diet , and the symptoms are a lot better, but i still fart quite a bit and it still smells awful. I ve found out that two of my uncles had a lactose intolerance around my age, but it eventually went away. I am 15 years old.
