I have constipation for past 3- 4 weeks. I took dulcolax about 3 weeks back and I passed stool but when last week I got really constipated, I avoided taking dulcolax and this monday and tuesday I really fell sick and couldn't pass any stool and couldn't eat anything and used to vomit out when taking water in high quantity. So I took 2 pills of dulcolax on monday and 2 pills of another medication that the chemist had prescribed on tuesday and drank lots of electral on tuesday so I passed watery stool on tuesday, yesterday again I passed some stool but today again am having problem passing stool. What is the solution to this chronic constipation I have got since the location, earlier I used to get constipated sometimes and sometimes during periods but this has become chronic now particularly for the past 1- 1.5 months or so. How do I get rid of it. Also, is it advisable to take isabgol/ triphala and for how long. What is lactulose. Are there any other remedies. I am really worried because I got very sick on monday and tuesday and now again am having problem passing stool.
