OK Hi everyone hope you all are having a good day, well I'm a 25 year old male I've had problems with my stomach since I was about 17 it all started with constipation and then from there just built up to abdominal pain and poor bowel movements I just went to a doctor and they gave me PrevPac, I told them that every time I ate something with in minutes I had to run to the bathroom, and the bowel wouldn't empty all out so I would be bloated most of the time and the feeling of gas and trying to burp but nothing, so they gave me Prevpac I've been on it for about 2 weeks now I've noticed a big change in bowel movement I mean I can really go now but the stool is narrow but very long only once the stool was hard and lumpy, the bowel movement is really good I don't feel stuffed or bloated that often anymore it's getting under control but I still get a burning feeling when I lay down every now and then in my stomach. I also started to take Atenolol for high blood pressure, I know I don't fit the common 25 year old but I've got a lot of stress so anyways my main question is the stool change, should I be concerned? I mean how narrow before I should be concerned?? I know they say pencil thin is alarming but I wouldn't say they are that thin they would be more like a marker in thickness and about an inch to an inch and a half wide and a good 8 to 10 inches long LoL I hate to be that graphical but I really need to know....thanks for looking
