We decided that, since her thyroid tests came back normal, we would take the situation into our own hands. She is already on a dairy free diet(2 years; we switched to almond milk
) because every time she consumes milk, she gets severe stomach pain and she feels dizzy. So, we were thinking what we changed in her diet at the time if weight gain. She started consuming excessive amounts of soy: soy milk (for protein), soy yogurt, soy butter, soy based protein bars, soy based cereal, etc.
