she is 21 and she has a complex learning disability and is on epilepsy medication. She shouldn't really be putting on so much weight in a short space of time. She only needs to lose about 4-5lb, it's affecting all he seizure medication
sorry I have just realised I have posted on mumsnet

randomly
For normal women I imagine putting on weight and converting it to muscle is fine. She has been stopped from doing anything normal and that is SAD more than hr putting on weight
Yes I imagine stopping a loved activity is more upsetting than putting on a bit of weight.
BMI isn't everything but she could put on
It makes me sad you use the phrase 'normal women' to say she is not one.
She could put on 1.5 stone and still be in the healthy range.
I have epilepsy and do understand rapid weight changes can be risky. Can you maybe speak to her neurologist about it to keep them posted?
I hope she manages to get back to her hobbies when covid restrictions settle down, not because of her weight which is absolutely healthy, but to make her happy.
