My 15 year old daughter has been suffering from weight gain and bloating for the past few months. At the beginning of the year she weighed 85-86 pounds in the morning. She started gaining weight at the beginning of February, and never stopped. She now weighs 99 pounds in the morning. 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. Well, she had been off of soy for a few weeks, and she got down to 93 pounds. Well, just recently started taking her vitamins that her doctor suggested due to abnornal blood work. Last week is when she lost the weight, and this past week, she has gained 6 pounds. Low and behold, the CoQ10 has soy in it! She also has very coarse hair and acne on her forehead which she never had before. Could this be causing her symptoms: weight gain, bloating, constipation, acne, coarse hair, severe headaches, poor concentration, shortness of breath, swelling of the ankles and legs, irregular period(she hasn't had a period in a year and she hasn't grown taller since she was 12). She is also on a gluten free diet to try and help her headaches. Our family doctor reffered her to an endocrinologist to check her hormone levels as well.
