Hi Feebiecat sorry to hear your husband is unwell. I was diagnosed with Type 1 diabetes in May 2011 aged 55 so big, big shock. No other family members have had either Type 1 or Type 2. I had a stomach bug about 3 weeks ago, first illness I've had since being diagnosed. I did all what your husband is doing, but also because I couldn't eat I found I had to reduce my background insulin by 1 unit for about 4 days as my readings were going low. When I did manage to eat some dry toast etc I found I still needed to inject my usual 1 unit for 10 grams of carb. I did not test for ketones as my readings were not going very high, but I know lots of people are advised to test for ketones whenever you are ill irrespective of readings. Hope he gets better very soon, Carole
