A large segment of the population cannot tolerate gluten, a substance found primarily in wheat, rye and barley. Some women with gluten intolerance have impaired fertility.
Wheat is by far the biggest source of gluten, since wheat is found in nearly all baked goods as well as thousands of processed foods. Gluten's effect may be indirect in that it damages the lining of the intestines and thus reduces absorption of essential nutrients from food. The gluten itself may trigger an undesirable immune response.
Some clinicians have implicated gluten as a possible cause of autoimmune diseases. Celiac disease is an autoimmune disease that is known to be caused by gluten intolerance.
It should be noted that some women with PCOS have at least one autoimmune disorder. The most common one is Hashimoto's thyroiditis, a condition where your immune system attacks and damages your thyroid gland. The result is hypothyroidism, which in turn leads to weight gain, hair thinning and infertility. If you have poor thyroid hormone function, you are very likely not be able to become pregnant and sustain a successful pregnancy.
Incidentally, one reason for high liver enzymes in women with polycystic ovary syndrome is NAFLD or non-alcoholic fatty liver disease. By one estimate, nearly one of ever two women with PCOS has this disorder to some degree. Yet it is often overlooked by doctors. NAFLD is commonly caused in part by the poor quality diet you're consuming. NAFLD could develop into something really serious. It is super-important to improve the quality of your diet. A good place to start is to eliminate fructose sweeteners from your diet. Fructose is thought to make NAFLD worse.
