My daughter is 14 years old and in her first year of H.S..She is 4'9", app.170 lbs., doesn't have her period, has no hallmarks of puberty,(little or no body hair, no acne, no moodiness) and looks like an 8-10 year old child. Symptoms throughout the years (now that we recognize their possible origin) include: brain fogginess, poor memory skills, social withdrawal, lack of concentration, no ambition /motivation, sluggish/tired.We recently had a battery of tests done by a ped. endocrinologist, including a bone age and a G.H.Stimulation test. We received the results today and tests confirmed that she is barely producing growth hormones at all and her insulin levels are completely off as well. Her blood sugar is fine, the doctor says she is not diabetic. The doctor has ordered an MRI to rule out a tumor. I am beside myself with this possibility and overwhelmed. Any information or advice you can give me on this subject would be helpful. Also, I would like to know, how possible is a brain tumor when a child is growth hormone deficient?
