Welcome to Healthcare Magic.
I have read your question fully and understand your concerns.
Thyroid disorders fall manly into two categories: Underproduction of Thyroid hormones called Hypothyroidism
. The symptoms of this are weight gain, low mood, constipation
, hair loss, intolerance to cold, dry skin, slow movements etc. Another category is over production of thyroid hormones called Hyperthyroidism
and the symptoms are; palpitations, diarrhoea, weight loss
, sweating, intolerance to heat, anxiety etc.
From what you have told in your query, you may be having hypothyroidism. You could get yourself tested for it. You could get a Thyroid profile done; it is a blood test which measures TSH and T4, T3 levels.
Hair fall could also be due to general aging process. Low Testosterone
again is a consequence of aging, as the person becomes older, his testosterone production falls.
I hope this answer has helped you.
