Three more case reports, three different stories. In each case gender dysphoria is related to the eating disorder, but in each case the relationship is different.
In the first case a trans woman (born male) had an eating disorder in adolescence. After sex reassignment surgery, her eating disorder returned.
In the second case, a trans woman developed an eating disorder when she decided to come out and live as a woman. At the time of the case report, she was on hormones and awaiting surgery.
In the third case, a trans man (born female) who had been living as a man had had long periods of being underweight and not menstruating. He denied dieting or caring about his weight, but he was very dissatisfied with his body. He was purging. Unfortunately, he also had alcoholism and had developed liver disease; he was therefore unable to take hormones.
There is no clear relationship here between transition and eating disorders. In one case, transition made the eating disorder worse. In another deciding to transition was linked to the eating disorder, but taking hormones did not cure the eating disorder.
These are, of course, case studies of only three individuals, so we can not draw any conclusions from them. As with other case studies, it seems that each individual is different.
However, for one of the patients, her eating disorder seems to have started when she decided to live as a woman, like the patients in this study, this study and this one. For some trans women, at least eating disorders are linked to gender dysphoria.
In the case of the trans man, his eating disorder went untreated for many years, like the trans man in this case study.
These cases are from a Swiss hospital program for gender identity disorder.
Case 1 – Trans Woman’s Eating Disorder Returns After Surgery
In early childhood, the patient was gender non-conforming and felt that she was a girl. As a teenager, she felt a deep aversion to her genitals and the development of secondary sex characteristics. She avoided swimming because she was ashamed of her body.
In adolescence, the patient was dissatisfied with her body and dieted until she was underweight (BMI=16.9 kg/m²). She held the weight for several months.
She cross-dressed “moderately” starting at age 20. She was distressed during her compulsory military service. She lived with a woman and later married, but was not very interested in sex. Her marriage only lasted 1½ years and after the divorce she decided to transition.
At age 36 she began taking hormones. Sixteen months later she had sex reassignment surgery and her eating disorder returned:
After the operation she again showed an increasing preoccupation with her body weight and shape. Her eating behavior was again restrictive. She still avoids highly caloric food and warm meals. Although her actual BMI is 20.0 kg/m², she feels too fat and seeks an ‘ideal’ body shape. After the first operation there were some complications and she had to undergo several re-operations. She herself wanted an augmentation of her breasts and is considering further cosmetic operations, which can be interpreted as persistent body dissatisfaction. She engages in excessive sporting activity and has repeatedly had minor injuries partly provoked by taking higher risks.
It is not clear why the eating disorder would return after she had surgery. By the time she had surgery, she had been living as a woman for a few years and taking hormones for over a year.*
Did the change in hormones after surgery affect her eating disorder? After surgery, her testosterone levels would have been lower than most cis women’s and low testosterone is linked to eating disorders in both men and women. In addition, for some women, higher levels of estrogen are linked to eating disorders.
Alternatively, did the complications of her surgery trigger a desire to control her body? Or had she been focused on changing her body with hormones and surgery and then when she was done, she focused on her weight? Or was her eating disorder a sign of persistent body dissatisfaction no matter what she did?
Case 2 – Trans Woman Develops Eating Disorder When She Transitions
The second patient had identified as a girl and felt like an outcast since early childhood. Her teachers did not allow her to play with girls’ toys. She started secretly cross-dressing in elementary school. She was suicidal at age 10 and said she wanted to live as a girl.
The physical changes of puberty were very distressing to the patient. She was attracted to men, but did not have any sexual relationships because she was afraid and because she did not want people to think that she was gay.
The patient attempted suicide at age 20 because of her gender dysphoria. After the suicide attempt, she got psychiatric therapy and decided to come out as a woman. She started to dress as a woman in public.
This is when the eating disorder began:
“Before his** coming-out, his body weight was 120 kg and his height was 1.97 m (BMI: 30.9 kg/m²). After the suicide attempt he started dieting and lost 40 kg of weight within 2 years. The minimal weight was 80 kg (BMI: 20.6 kg/m²). The eating behavior at the beginning was dietary restriction, followed by purging, binge-eating, and self-induced vomiting. He consumed anorectic medication and engaged in excessive sporting activities. The decision to come-out went hand-in-hand with the ambition to attain a more feminine shape by losing weight. He is convinced that his acceptance as a female would depend greatly on an ideal body shape. The patient is currently under hormonal treatment and the surgical reassignment will soon take place.”
Deciding to transition caused this patient to develop an eating disorder as she tried to change her shape. Socially transitioning and taking hormones did not cure her eating disorder.
Case 3 – Trans Man with a Long-standing Eating Disorder
This is a very depressing case.
The patient preferred boys’ games growing up and felt he belonged with the boys. At age 6 he was sent to the school counselor because he refused to play with girls. His breasts caused him distress, but he did not bind them or self-mutilate. He got his period at age 14, but had secondary amenorrhea (no period for six months or more) for many years.
He was attracted to females and had had only female partners. His partners accepted him as male.
He had been living “in the male role” for over 20 years, but had never had any medical treatments for his gender dysphoria. He had refused to take estrogen for his amenorrhea, however.
The patient was underweight when he came to the gender identity clinic and he had been very underweight in the past.
Her** minimal weight at the age of 40 was 33 kg (BMI: 13.5 kg/m²).*** She reported longlasting periods of underweight accompanied by amenorrhea. She denied ever having intended to diet deliberately. She reported no binge-eating or self-induced vomiting, but she was purging. She denied preoccupation with her weight but reported a strong body dissatisfaction.
The authors could not treat her with hormones, however, because of “severe liver disease and the psychic instability and alcohol dependence.”
Although the patient denied it, it might be that he was keeping his weight down in order to avoid having periods.
Social transition did not help this patient with his eating disorder. We can’t know whether or not hormones would have helped him since he was medically unable to take them.
Gender dysphoria is clearly linked to the eating disorders of the two trans women and possibly linked to the trans man’s eating disorder. Transitioning did not cure the trans women’s eating disorders, however. In one case surgery led to the symptoms returning after many years.
