Hello, My name is Pam and Im 63 yrs old. Advice wanted please. Was diagnosed with diabetes Type 2, 3 years ago. Have had UC for 7 years. I control diabetes by watching my weight and diet and exercise. I now have to have a colonoscopy in 2 weeks time and I will not be able to eat any solid foods for about 27 hours beforehand. Only to drink clear liquids. Any tips on what to have before procedure?? Surely not just water or tea without milk.
