A recent study published in the Journal of Diabetes and Metabolic Disorders claims that eating disorders may increase the risk of developing diabetic retinopathy in people with diabetes. According to research, diabetes is characterized by high concentration of glucose in a person’s blood. This excess glucose damages tissues in many parts of the body, including the feet, heart, and eyes.
After combining data from several studies, academics from Anglia Ruskin University (ARU) found that people with eating disorders were 2.94 times more prone to diabetic retinopathy than people with no eating disorders.
Diabetic retinopathy is a complication that affects the eyes of a diabetic person. It usually causes blindness or vision loss in people by damaging the blood vessels of the light-sensitive tissue present at the back of the eye or the retina.
A person suffering from diabetic retinopathy may experience certain symptoms as the condition progresses. These symptoms include spots or dark streaks in the vision, blurred vision, or blank or dark areas in the vision. In addition, the person may notice fluctuations in vision or even complete loss of vision.
In the study, researchers considered and linked certain eating disorders with an increased risk of diabetic retinopathy. One of the disorders considered is anorexia nervosa. In this disorder, people usually try to keep their weight extremely low by limiting their food intake or burning too many calories through exercise. Another disorder noted in the study is bulimia nervosa where a person eats large amounts of food over a short period of time and then attempts to purge it by vomiting or using laxatives.
They found a positive association between pathological eating disorder and the risk of diabetic retinopathy, according to study lead author Mike Trott. According to the findings, people with eating disorders or those who deliberately do not take insulin to lose weight have poor control of blood sugar levels.
Researchers have suggested that doctors should pay special attention to people with eating disorders. Any abnormal eating behavior in people should be addressed expeditiously to reduce the risk of diabetic retinopathy.
