Q:

I am very obese with a lot of belly fat. I usually inject my insulin in the stomach area and have wondered if the insulin is being blocked in any way because of the amount of fat there.

A:

Research indicates that the length of the needle and how deeply it is injected into the fatty layer does not affect the absorption of insulin. However, for people who have a great deal of belly fat, it may just take the insulin a little longer to get into the blood stream, but the fatty tissue does not “block the insulin.” If you are concerned that your injection site is somehow affecting absorption, try a different site and see if it has an impact. You could try the fatty tissue in the back of your arm or the fatty tissue on the outer side of your thigh. If you are using a very short needle (6 mm or less) you may want to switch to an 8mm length (5/8 of an inch) this may allow the insulin to act a little faster than it might otherwise. Even with these changes, if you still find that your blood glucose levels are high, chances are that the insulin doses will need to be adjusted by your healthcare provider.
