Before I start I need to preface with the fact that I know she has some disordered and unhealthy eating behaviours-I'm just wondering if it qualifies as an actual eating disorder?
DD is 16. She has always been very slim due to having no interest in food and playing sport daily, including long distance running. She's been like this since she was a very small child.
About 18 months ago she got a long awaited and much needed ADHD diagnosis, and the medication has really helped her. Unfortunately it also further reduces her appetite.
As part of the ADHD diagnosis she saw a therapist who said she had mild body dysmorphia- she's a very pretty girl at the bottom end of the bmi chart and genuinely believes she's unattractive and chunky. She likes being slim and will prioritise that over food which is easy for her as she really isn't fussed about eating. (She is very similar to my lovely MIL who has never weighed more than 8 stone in her life but is still sporty and active.)
Over the summer when she wasn't doing school work she went off her medication and tried to eat more. She increased her weight from 6 stone 12 to 7 stone 3 (at 5 foot 4") and was pleased, and in the green bit of the bmi chart. However now she's back at school she's stopped eating lunch as apparently she worries if she eats a big meal and then tries to restrict the next day to balance it out. It's not helped by the fact that she's surrounded by girls who are worried they have gained weight and who talk about losing it constantly.
She does eat. I make her a big breakfast each morning (poached egg, sausage, smoothie) and she's fond of some foods and I'm relaxed as long as she's getting calories. She's just has a reasonably large Mexican quesadilla, nachos, chips and 2 churros for dinner. She doesn't have the need to control herself or her environment that I associate with anorexia, but I am aware that worrying about eating a big meal when you're the weight she is is isn't normal.
I'm keeping an eye on things, but after nearly 2 years of mental health disruption as we sorted out the adhd and the negative self worth caused by her late diagnosis I'm also loathe to start her on more therapy if (for example) she's just active, likes being slim and is prepared to occasionally restrict food to achieve this (again, this is how my MIL has lived her entire happy and successful life so whilst I don't necessarily agree I cannot argue that she's been damaged by it. The only time I remember her upset was when chemo made her put on weight and none of her clothes fitted. She lost her hair and her breasts but got back into a size 8.)
So I suppose my question is- so I need to do more and worry more?
