Hi guys,I thought i'd share with you my latest experiance with you.I wont make it long.I suffer from IBS C. Diagnosed as post infectious IBS c. I have had all the tests colonoscopy, barium enema etc.I have constipation every day. Manageable but constant chronic constipation and bloating.Recently I changed my heating system. I had a water tank and immersian heater. I upgraded to a combi boiler. This was because my heating system was old and needed replacing. Nothing to do with my IBS.My plumber commented on the dirty water my old tank was circulating round the house.Anyway to cut a long story short as the new system was installed I began to feel better. More energy, no bloating and a slight improvement in my BM. As the weeks went on my skin felt great and my BM were returning to normal. My stomach flattened out and I felt great. This went on for weeks. My BM's returned to near normal and I thought that the water quality (or lack of) had caused my IBS. I didnt want to post to get people exited until I was sure. Unfortunately my symptoms are gradually starting to return. Im still not as bad as I was but im heading in that direction. Im constipated again and the bloating is starting to return. I feel like crying.Have any of you out there got any water quality issues. Do you have uncovered water tanks at home? Old boilers?I'm sure there is some connection. I havent managed to reason out why my symptoms have returned. Its frustrating.I should mention that my Partner and daughter have both seen improvements in their health since we changed the water supply.Any thoughts on the matter would be welcome.
