Do i have overactive Thyroid?

I''m a 17 year old boy and i have noticed these symptoms that are very noticable not only to me but also other people, these are the symptoms I''ve been having,

Tiredness despite having plenty of sleep
Very hyperactive
Full of energy
Significant weight loss
Eyes look and appear and also feel very tired to me and other people.

I''m not sure if this is overactive Thyroid, these symptoms look very similar to over active Thyroid
but im not sure if this is just Puberty and ragging hormones, what do you think?

Recommended Answer:
I had this a few years ago. If you also can eat loads and still lose weight without dieting, sweating all the time and are always warm or hot, irritable?
Then it sounds like you are correct.
I had this for 2 months but did not realise it. It was other people who noticed the changes(apart from the weightloss) so i went to the doc''s and yes it was an Overactive thyroid.

You only have to take a blood test and they will tell you.
