I had bowel issues for years, never knowing quite what it was. Constant swings from constipation to diarrhea. Not horrible, but regular episodes. Eat and I better be around a bathroom pretty close and quick.

Changing my diet was probably a big change and could have been what resolved it, but I think the metformen could have also been an issue.

That is just one of the many reasons why I say the ketogenic diet gave me my life back. Got off all medications including 100 units of insulin a day and lost 100#. Have not felt this good in ten or twenty years.
