Was wondering if anyone has erratic stoma output 9 months after colostomy surgery? I was having fairly predictable stoma output, about 3 times in a 24-hour period. In the last few weeks, my BM pattern has become very erratic. I will have a lot of output one day and then not have any for 2-3 days. The days I don't have output, I feel miserable with bloating, trapped gas, burning pain in my belly, and heartburn. I have to take increased doses of Miralax and Milk of Magnesia to have output again. The laxatives are very harsh on my stomach. Two GI's I am seeing have no clue as to why this is happening with me. Any insights you can share would be appreciated.
