What kind of milk do you mean? Cows milk, soy, almond. I would suggested you read the labels for carbs and check with either your primary or endo to see if the number of carbs are okay for you to ingest?
Hello,
milk does contain lactose, a form of sugar that can affect blood sugar.
however, dairy products, particularly those which are not sweetened are usually considered safe for people with diabetes (assuming no other reason to restrict them). Higher fat versions, and even cream will have less impact on blood sugars. I use cream in my coffee rather than milk as fat has little impact on blood sugars.
