Thin privilege is having doctors treat you with respect, not contempt because of the size of your body.

I have bad knees; my family collectively has pretty poor joints that are prone to sprains and strains. I am fat, my family is mostly in their ‘healthy’ (BMI-bullcrap) weight range. I dislocated my knee on Xmas Eve, and cracked the knee cap as well. I needed surgery. The morning after the surgery the doctor, whom I had never met, told me it went well, my cartilage was ripped up badly and that I should try to lose weight. He didn’t ask me about my lifestyle, he didn’t ask me about my food intake or about the fact that I have a disease that makes it very difficult for me to lose weight (Hashimoto’s hypothyroidism). I burst into tears, in front of him and 5 medical students/junior doctors, they did not offer to comfort me. They stood there staring at me as I tearily tried to explain that I had been dieting since I was 7. I had tried everything and had recently been working out 1.5 hours a day at the gym. They left. Just like that. I was a young woman, clearly very distressed, and they just left.
