I am inclined to think your dad is lying. He is probably just bitter about the divorce and people who are divorced, generally don’t say very nice things about you.
What are the symptoms of hypothyroidism?
In hypothyroidism the thyroid is underactive and so the rate of metabolism slows down. As hypothyroidism usually develops slowly you may have no symptoms until the condition is well advanced. The symptoms you may have might be blamed on old age and can vary in severity but as your metabolism continues to slow, the symptoms should become more obvious. The symptoms may include any of the following:
* Feeling tired and lacking energy.
* A tendency to feel the cold more than healthy people.
* Heart may beat slower.
* Weight gain and difficulty in losing it.
* Irregular or heavy periods.
* A hoarse, croaky voice.
* Forgetfulness.
* Depression.
Later symptoms may include constipation, dry, pale skin and dry hair, which may be brittle and break easier.
I hope that helps.
