I just learned about Mamasource and this is my first time on the site.
I also have a 14-year old son who has ADHD. He was diagnosed when he was in 1st grade and has been on medicine ever since. It has definitely been a struggle in every aspect.
In the beginning he had issues with his weight. He didn't eat much and was not putting on weight so we had to keep an eye on that and monitor the medicine. Now it is just the opposite, he is eating me out of house and home and is taller than me (I am 5'2") and weighs about 130lbs. He has had changes in medicine which I think helped him want to eat again. His dad and I are short. Again I am 5'2" and his dad is 5'8". So we wonder where he got his height from?!
Your son could start a growth spurt any day now or maybe his medicine is affecting his growth. Honestly, it is so hard to know and I don't believe the doctors know either. They have their theories but they can't tell you definitely what could be wrong. They can just adjust the medicine and see what happens.
Just great to correspond with another mom with a child the same age as my son who is going through the same struggles.
