But that isn't the only ​way that hypothyroidism can cause weight gain. Believe it or not, your thyroid also influences other hormone systems in your body. Here's an example of what can happen to your hormones when you have hypothyroidism: Progesterone levels may fall leading to estrogen dominance and weight gain in the hips, butt, and thighs (low progesterone may also contribute to infertility)
Cortisol levels increase causing weight gain in the abdomen
Insulin levels increase leading to abdominal fat
Leptin levels may increase causing weight loss resistance
Testosterone levels may change as sex hormone binding globulin falls
So what happens is as thyroid hormone falls you get hit with a double whammy: Hypothyroidism leads to a slowing of your metabolism and causes other hormone imbalances which then lead to further weight gain. The big problem is that simply fixing your hypothyroidism by replacing thyroid hormone with Synthroid or levothyroxine does NOT fix the other hormone problems. It may resolve your hypothyroid symptoms like hair loss, fatigue, and brain fog - but it usually doesn't lead to weight loss. Why? Because ​the other hormone problems still persist! ​But what about the weight gain from hypothyroidism itself?
