I am a type 1.5 diabetic on an insulin pump. Recently I have changed my diet to a Mediterranean diet and am experiencing many lows. My doctor lowered my basal rate but I am still experiencing lows occasionally. Can you just be prone to having lows or am I doing something wrong in counting my carbs? Also I bruise a lot from my infusion set; is this normal?

The type of fat you eat, particularly when you combine it with carbohydrates, can affect how much bolus insulin you need to take with your meals. When you eat meals that are higher in fat, sometimes more insulin is needed to cover the carbohydrate in that meal. Now that you are eating a Mediterranean diet, chances are you are eating less fat and may need less insulin with your meals . It’s not just the carbohydrates that affect how your meal time insulin is working, but the fat content of the meal as well. Also the Mediterranean diet is higher in fiber, which can affect how quickly carbohydrate gets absorbed, and this may also be affecting your numbers. The best thing for you to do is to make an appointment with a nutritionist experienced in working with pump patients to look at the factors that may be affecting your insulin doses. The person experienced in pumps can also go over different types of infusion sets to see if there is one that will make you less likely to bruise.
