I am a C-type, but my BM's improve during this time of the month. My BM's are looser and I'm fine. A week later and I'm back to C again. This ties up with those that are D-types - their BM's are looser too.Not so good for them!So you'd think that if it is so connected to hormone levels, the medical profession could look into it and find a pill to fix it!Afterall...... they have developed hormone pills for the symptoms of menopause, and to prevent pregnancy etc. They should look at our hormone levels. This won't help men of course. However, it is a fact that more women suffer from IBS than men. So it makes sense. I'm sure the answer is related to hormones.
