14yr old boy newly diagnosed - symptoms

My 14 year old son will be seen by a paediatrician next week after blood results showed thyroid disease (genetic unfortunately). Will find out more at the appt but am increasingly concerned about how forgetful, confused, dopey and generally spaced out he has become. Fatigue and constipation were his main symptoms which led to blood tests but his declining ability to function effectively particularly at school is worrying. Has anyone else witnessed this in a teenager?

L30yng, unfortunately children and adolescents do become hypothyroid. Your son's symptoms will improve once he is optimally medicated which is likely to take a few months, but he will notice improvement along the way.

Maybe have his Iron - Folate - B12 - VitD checked too. My grandson was so low in all of them - and yes VERY sleepy !

Hope you soon see improvements.....


Hi, I'm sorry to hear your son is so poorly. I wanted to offer some reassurance though as my 14 year old daughter was in a similar sounding state until recently, and is now well on the road to recovery. She was so tired she was barely able to attend school. When she was in school, she had such debilitating brain fog that she felt completely useless, and experienced similar-sounding 'spaced-out' feelings. This, plus IBS-type symptoms and more ... Anyway, she was eventually diagnosed with Hashimotos (autoimmune hypothyroidism). She is now on a relatively low daily dose of thyroxine and has made quite a few changes to her diet to support her recovery. She is sooo much better! In school every day, still part time but gradually building up to full days. She has so much more energy and focus, and has got her 'bounce' back - even enough to be a proper stroppy teenager some days ;0)

I do hope your son gets the diagnosis and support he needs to get him on the road to recovery x

Is your son properly hydrated with water? Lots of his symptoms could be not enough water in his diet; Does he have proper nutrition? Real food? Having trace minerals and lots of vitamin C? it is clearly a problem but I would be wary of thinking it cant be helped because it is genetic. (Not saying you think that) Sometimes things that are labelled as genetic can be nutritional deficiencies that caused a problem in several generations, but could be remedied with enough nutrition.Fresh juicing a couple of times a day can help hydrate if he doesn't like water. It can help reset the body. Cutting out gluten and sugar?

The body can solve problems if it is given the materials. Sometimes people cant tolerate what we now think of as the standard diet.
