welcome to HealthcareMagic
is a condition where you metabolism
is fast in such cases you will never put on unless your treatment is effective .Once the treatment is over may be you will gain weight or else nothing will help.Just in case you try some formulation of supplements ;if it contains steroids
in any form it will do more harm than doing good .So my advice is to consult your doctor or if required a Endocrinologist
who will help you in treatment.
