My girlfriend, age 20, has been trying to get a diagnosis since she was 15.
She is overweight, with a BMI above 30, despite eating less than 1500 calories per day. Most of her body fat is centralized on her stomach.
Since she hit puberty, her menstrual period has been extremely painful accompanied by clots. This subsided with the use of birth control.
She is prone to bleeding in general and is very easily bruised. Bruises often take two weeks or more to subside.
She gets sick quite often, and when she is sick it lasts for a long time. Illnesses that I get over in a day or two put her out of commission for well over a week.
We suspected a hormone disorder, but she recently saw an endocrinologist who seemed to dismiss that idea. He is waiting on the results of a few tests before he makes a final call, however.
