I have been using laxatives since I was 16 (now I'm 24), mostly ones containing senna, and I've consumed large quantities of them. I recently decided to stop altogether, and it's been very hard on my digestion. I get bloated and have a lot of gas all the time. I can't pass stools without taking fiber (psyllium). Will my digestive system ever be normal again? What should I eat to improve my colon function?

As you have discovered yourself, the long-term use of laxatives can cause intestinal damage. Those containing senna can be among the most damaging. The only laxatives that are "safe" are those that are natural, like bran or other bulk agents such as Metamucil -- and these are not true laxatives; they increase stool bulk and make it easier to pass. Laxatives sold over-the-counter are safe when taken only rarely and according to package instructions.

It is likely that over time your bowel function will return to normal (assuming it was normal to begin with). However, this may take many weeks or months, or even longer, as every individual is different. You can avoid constipation by eating foods high in fiber, including fruits, vegetables and whole grains (bran and wheat), which contain the insoluble fiber that is good for your colon. These may cause gas, so test your tolerance by eating small portions for a few weeks to gauge your response. Drink at least eight 8-ounce glasses of water a day (do not substitute soda, juice or other fluids) and exercise regularly. You may need to put up with bloating and gas while you readjust -- be patient, and be reassured that it is not dangerous.

Above all if you have not been evaluated, please see your doctor. You may have a medical cause for constipation that requires treatment with other methods.
