My daughter who is 7. She had the worst sweaty hands and feet. Its really bad where she can't hold a pencil. What's the appropriate treatments for hyperhidrosis kids?
I've had HH all of my life and had similar issues as your daughter when I was growing up. One of the most important things you can do for her is to just be as supportive as possible and to be an advocate for her at her school. My parents always made sure to tell my teachers so they would not discount sloppy handwriting, wet or torn papers, or would fine me for damaged books. I was bullied by teachers and peers, so make sure that she knows that you will be her biggest advocate if she has any issues with others.
Iontophoresis, Highly recommended, but I also tried it at a young age and found it difficult to endure. It was a bit of itching and most kids hated sitting still for it.
At that age, I'd recommend starting with small treatments and work your way up if they do not work. Drysol was one of the first treatments I tried. I carried a little towel with me everywhere (still do), I also tried carrying a rosin bag (like that gymnasts or baseball pitchers do).
Oral pills are also a possibility, but talk to her doctor about it - she's so young and they do have side effects for everything.
ETS surgery is not recommended for kids as it had good and bad side effects.
Honestly, the best thing you can do is be her biggest support. Encourage her to still participate in the things that she wants to do but that her sweaty hands make things more difficult. I played the guitar, I was a softball pitcher, I played golf, and I had to accommodate my sweaty hands for everything, but it did instill a confidence in me that I wouldn't let my condition limit the things I do in life. Encourage her to talk about her condition too. Kids can be jerks, but if they realize that actually, there's a legitimate medical reason her hands are wet, it's harder for them to make fun of. If she has a hard time in a class because of her hands, talk to her teachers, see what they can do to accommodate. And in the meantime, go to her doctor or find a good dermatologist that can start setting her on a course of different treatments. Again, at this age, start really small and work your way up to the bigger treatments if the need arises. It's great that you're here and that you want to help!
