As some of you may know, I am a long time sufferer of chronic constipation. Over the past 20 plus years, I have tried everything under the sun to get relief, including Zelnorm and Amitiza. Eventually, everything stops working except for bisacodyl based stimulant laxatives (Dulcolax). I don't take it every day as I know it is not that healthy an option. I use it every 3 to 5 days - when the buildup gets uncomfortable. The good news is that it works. The bad news is that it causes other painful symptoms like abdominal cramping before it works. One symptom which has developed over the last few months is terrible distention. I take three tablets at bedtime. I can usually sleep through the night before a stomach ache wakes me up about 6 AM or so. I usually cannot go until about 9:30 or 10, so there is a period where I am uncomfortable with cramping. I can deal with that. But, lately, my abdomen and stomach are also hugely distended when I wake up. My normally flat stomach looks like I swallowed a volleyball. It is tight as a drum and is sore to the touch. I can't even get into my jeans. All of this goes away after two or three bowel movements, but I am worried that I may be having some kind of dangerous reaction to the bisacodyl. Has anyone else experienced this with a stimulant lax?
