Hi thanks for question
I read your thyroid
profile report, which is absolutely normal.
There could be few reasons for weight gain other than hypothyroidism
One of the commonest reasons for gaining weight is erratic eating not necessarily over eating
The second reason could be lack of any physical activity
The third reason could be too much of the fats in your diet
Fourth reason could be depression
Fifth one being stress
Sixth could be lack of sleep and finally
A rare disorder known as Cushing’s syndrome, caused by an excess of the hormone cortisol
, which tends to store fats.
Consult a physician,who will investigate you for cause of weight gain
Hope this answers your question
