By Lisa Rapaport (Reuters Health) – Patients whose diabetes improves after weight-loss surgery may also be less likely to suffer complications like eye and nerve damage, a U.S. study suggests. Patients in the study had what’s known as type 2 diabetes, in which sugar levels in the blood rise too high because the body can’t use or make enough of the hormone insulin to convert food into energy. After the weight-loss operations, some patients saw their diabetes go into remission, which can occur when blood sugar falls back to a healthy level.
