Case of type 2 diabetes mellitus with edema resulting in subcutaneous insulin resistance syndrome

Subcutaneous insulin resistance syndrome caused by obesity, induration at the injection site, skin temperature and other factors is common clinically, whereas resistance events caused by edema are relatively rare. This article introduced a case of a woman with type 2 diabetes mellitus with heart failure edema. Her blood glucose control was significantly associated with the level of edema. Excluding other factors, it can be concluded that edema might lead to subcutaneous insulin resistance syndrome, even if the edema at the injection site is not obvious.
