Are there any medically recognised eating disorders that can cause weight gain? ?
There’s a commonly recognised eating disorder called bigorexia, which is most common among men, where they eat loads and work out loads to get abnormally large muscles. They may also take steroids. They see themselves as small and weedy, even when they are actually muscular. There is also binge-eating disorder, which is when the patient eats vast amounts of food, like an extreme example of comfort-eating. One example I found of this was one girl who ate an entire loaf of bread, a whole packet of sugar and a tin of syrup in one sitting. Bulimia nervosa, whilst it often causes weight loss, can also cause weight gain, as they swing from bingeing to purging. If they eat more calories than they purge, they can also put on large amounts of weight, although it is more commonly heard of for bulimics to be normal weight or underweight. Obesity is also technically classed as an eating disorder, and is therefore the most well-known of these. Often it roots more from upbringing or personal habits
