Our expert says:
If your thyroid function tests indicate that your thyroid is normal then you should under no circumstances take thyroid hormone supplements as this will do more harm than good. You could also suffer from insulin resistance for which the dr would have to test your blood sugar and insulin levels preferably by doing a so-called Glucose Tolerance Test. Some women who struggle to lose weight, also suffer from Polycystic Ovarian Syndrome (PCOS) that is associated with insulin resistance. However if as you say, you gain 3-4 kg at certain times of the month and shed them again, I would suspect that you suffer from premenstrual syndrome (PMS) and that the weight gain is not due to fat, but water retention caused by changes in female hormone levels. Click on 'Diet' at the top of this page and then on 'DietDoc's articles' and read article 57 'PMS and diet' to obtain tips on what you can do to prevent these symptoms.
