Hi My Daughter Is 9 And Has Vitiligo Asthma And

Hi my daughter is 9 and has vitiligo asthma and eczema and has allergies to penicillin, keflex and ibuprofen. She plays hockey 5 days a week for at least an hour per day, she walks to school and is very active. She has been gaining weight lately around her stomach to the point that she has gone up a size of clothes and we had to replace some hockey equipment mid season. I wondered if I should be concerned about hypothyroid. She is always constipated, her baby teeth fell out very late and it took forever for her adult teeth to come in. She is also short for her age. She is the shortest in her class and one of the shortest on her hockey team.
