I am 53 years old. For the last 20 years or so I have been suffering from dysentery. Usually I take allopathic medicines prescribed by the doctor. So long as the course continues, dysentery is under control but stopping of medicines cause recurrence of the problem. I have to go the latrine for 3 to 4 times, sometimes even more. Besides taking aqua guard filtered water, I eat home-made foods without spice and oil. What should I do to get rid of the dysentery problem.
