Chronic Constipation or Something else?

For almost two years now I have suffered from extremely painful and odd stomach problems. I am 17 and feel like I have the insides of a 90 year old woman. I am always bloated and constipated and have gained weight out of nowhere and steadily gaining more. I eat healthy and exercise 3-4 days a week. I had a colonoscopy last year and the results were just internal hemeroids. I go to the bathroom 1-2 a week if im lucky and it is very painful and hard to manage. The doctors say that there is nothing wrong but there must be! I am always feeling nauseousness regardless of if and or what I eat. It hurts so bad sometimes I can't even get up for school or other daily activities. I was put on two strong laxatives. I took a stir in twice a day and  24 mg pills twice a day. They did nothing. Please help! Is anybody out there suffering this?

Welcome to the gastroenterology community!  What laxatives did your doctor put you on?  Did you try a high fiber, lots of water, lots of fruits and vegetables diet first?

They had me on Amitiza 24 MCG capsules and polyethelene gylcol powder. I took the pills and the powder twice a day. I also ate fiber one cereals and bars. I have always ate alot of fruits and vegetables.

That's very strange that your doctor started with those laxatives first.  I would recommend you try miralax or milk of magnesia which are both over the counter.  How much water do you drink?
