the helmet would not affect his growth or pituitary gland in any way. if you are concerned about his growth as a grandparent you may want to suggest to his parents about seeing a pediatric endocrinologist for a consultation.
can wearing a helmet for "flat head" syndrome affect the pituitary gland and possibly the growth of a child? . our grandson was a healthy robust normal size (weight and height ) child and was growing as he should. then he was prescribed a helmet to help shape his head. that was when he stopped growing. he will be 10 in 3 months and is smaller than many 6 year olds. he is perfectly proportioned but is tiny. could the helmet have damaged his pituitary gland and affected his growth?
