Hello! Thank you for the query. It is better to find out the reason of constipation before any medicine usage. At your age, such chronic constipation along with bloating, stomach problems, loose motions can indicate colon cancer. And this is the first condition which should be ruled out. To do that colonoscopy is advisable. Other reasons of constipation are diet (low fiber products and low mineral water intake), thyroid disease, medicines (Ca-blockers, antidepresants), chronic bacterial infection. Only after ruling all possible reasons of constipation, stool softeners can be used. Hope this will help. Regards.
