The hospital consultant has changed my Lantus insulin to Tresiba for better control. However after 5 weeks of taking this I’ve had diarrhoea & stomach cramps for 3 weeks now. I have no other symptoms & have been to the GP (albeit it was a specialist GP) who said they’ve seen a lot of people with diarrhoea & no sickness & to leave it another 2 weeks. I did express concern that this would be 5 weeks with this condition & he said that’s ok. It’s only today that I’ve just made the connection with this & a change of meds. I’ve googled side effects & this is one of them. I was concerned that it has taken 5 weeks for these to appear but I also read someone’s experience where it did take a few weeks for them to appear & then they went back to Lantus & were ok the next day. I’m going to ring the diabetic nurse today but just wondered if anyone else has experienced this ?
