lybrate-user, Thanks for the query. Usually PCOD and hypothyroidism both are known to lead to increase in weight. Or other way round, PCOD is usually seen in over weight females. And hypothyroidism leads to weight gain. But the sudden loss of weight that you have experienced is difficult to explain. But the weight gain is due to hypothyroidism. When on treatment for hypothyroidism with adequate dose of levothyroxine TSH should be maintained between 3 to 4 mU/L, then only all the symptoms including weight gain can be well controlled. Since no age is mentioned, it is difficult to comment regarding other problems associated with PCOD & high TSH. Thanks.
