My husband was diagnosed with type 2 diabetes a little over a year ago and is being treated with Matformin. In spite of having the tablets changed to slow release medication, he still quite often suffers incidents of uncontrollable diarroeah. This is making him depressed and unable/unwilling to lead his normal life. His GP assures him this will get better....but at the moment, he is embarrassed and humiliated on a regular basis and I am worried about the psychological damage this is doing. Does anyone have any advise to offer.
