only a doctor can diagnose you with ibs or another related gastrointestinal disorder. but from what you have shared it seems your increase in bowel movements is due to your increase in fiber. especially if you are not feeling abdominal pain or bloating and your bowels are not hard or really loose. for more on the symptoms of ibs see this webmd article. if your daily bowel movements are due to increasing your fiber as i suspect your bowels will likely evolve to less frequent as your body adapts. if you feel something is wrong though don't hesitate to see your healthcare provider. best of luck to you!
do i have ibs? 3 bowel movements a day. i'm a 20 year old male and lately i have been having about 3 small(not too small but smaller) bowel movements daily usually after each meal. . i eat a lot of fiber 35-40 grams per day and usually drink a lot of water. is this normal for my high fiber/lots of water diet or is this progression a sign of me possibly developing ibs or colitis? . for the record this bowel movement increase does coincide with a rise in my fiber intake prior to the rise i usually had a bowel movement daily.
