I was working on my homework and brown liquid faeces came out (I did not feel like I had to use the lavatory at all and my last bowel movement was midday today). I googled this and when people had clear liquid come out (mine was brown) it said they need to eat more fiber . I do not think this is my problem as I am a vegetarian and I do it the healthy way (I eat lots of fruits, vegtables and whole grains – not just processed junk). There is Alzheimer’s in my family, and I have seen my grandmother have accidents, and she did not know she did not have to go to the restroom. Is it possible that a 17 year old girl could have it? If so, what can I do to stop this from happening? If not, what is wrong with me. Please help me; I am so scared of this happening again (especially if it were to happen in public). My medical history: I have had no gastronomic problems. When I was 15, my liver was failing, but it regenerated so it is okay now. Currently I take 50 miligrams of Vyvanse and 20 milligrams of generic Adderall for ADD as needed.
