More importantly, let's discuss what is causing your unexplained weight gain, and why whatever you have used to lose weight (so far) has never worked.
Doctors until now have been focussed on the thyroid and its effect on metabolism. Sure, your thyroid controls your metabolism and when it becomes 'underactive', it becomes impossible to burn fat.
But thyroid function is just a part of the problem.
Your adrenal glands that sit at the top of your kidneys which release cortisol and adrenaline hormnones into your bloodstream, are crucial to your metabolism and weight gain.
These glucocorticoids, naturally secreted steroid hormones, are essential for the maintenance of metabolic function.
Clinical studies have linked excess glucocorticoid (in particular cortisol) levels, with adverse metabolic function resulting in abdominal obesity.
