My teenage old cousin recently developed an autoimmune disease. She's had a very restrictive diet lately and is avoiding all dairy/high protein food products to feel OK. Unfortunately, the doctors have still not diagnosed the condition.
She's been a very healthy girl all her life till this past summer. She recently fainted and I can't imagine why this is happening to her right now. I'm in the process of getting more information about her symptoms but I thought an early start here would help. She has some joint pain and is basically restricted to very few meals or else she feels weak.
Please help.
