Lots of love from another PCOS sufferer!
I know exactly how you are feeling. At least you were diagnosed at a fairly young age; I wasn't diagnosed until I was 27 years old!! I spent my entire teenage years trying to get doctors to figure out what was wrong with me. I was gaining weight like crazy, and losing it seemed like it was impossible even though I was dieting like crazy. My acne was horrible growing up (to the extent that I had to go to a dermatologist several days a week!). I had excess facial hair I was forced to either shave or wax off all the time. I was always cold, and not to mention being VERY irregular with my cycles. I averaged about 4 months between cycles, but my longest was 10 months. At the beginning all the doctors said that it was "just because you are a teenager. Things will regulate out eventually." Well that never happened, so they put me on birth control to get things regulated out, but other than a thyroid test (which came back normal), no other investigation was done.
Finally last year I mentioned the symptoms to my new general practice doctor, who asked me if I had been diagnosed with PCOS. I asked my new gyno about it (I'd just moved to Kansas), and he reviewed all of my symptoms with me. Based on what I told him, plus the fact that I tend to gain weight around my middle, he diagnosed me with PCOS. Unfortunately the tests to confirm the diagnosis are VERY expensive, and my insurance will only cover about 10% of the costs. So it's never been confirmed with testing, but the diagnosis was made.
Because I can't post links yet, run a google search for PCOS and you should find the major support group; it's a .org. They have TONS of info there.
Basically, 20% of the time PCOS is caused by a thyroid condition. You can treat that with medication and the PCOS goes away. 80% of the time PCOS is caused by Insulin Resistance, which is basically where your body can't process sugars correctly because the cells are semi-immune to insulin (also called pre-diabetes). Metformin is an insulin re-sensitizing drug, which is why it seems to work so well with PCOS treatment.
My insurance would laugh at me if I asked it to cover Metformin (yes, I have crap insurance), and quite honestly I'm not into jumping right to that option right away because of some of the side effects. If you check out the link, you'll see about halfway down the page that an alternative therapy is Cinnamon Bark (Caissia Cinnamon). You can buy it at any store, and it has the same effects as Metformin; it's just not as powerful. I've been using it at the recommended 1000mg dosage and it does seem to help. Here is what the support group says about it:
The Cinnamon you get is powdered Cinnamon bark, like what you buy at the grocery store. The variety is called Caissia Cinnamon. Some people prefer capsules, as it is easier to measure and you don't have to have Cinnamon with everything. If you do get capsules, be sure that it is the powdered bark, or at the very least, a water-soluble product. You want to be careful NOT to use Cinnamon Oil, as it is difficult to process and flush from your body, and it does not have the insulin-sensitizing effect. If you are using regular Cinnamon from the store, a teaspoon is about equivalent to 500 mg. You can take it sprinkled on cereal, in tea, on desserts, mixed in applesauce, and so on. While previously, dosages were recommended up to 4,500 mg/day, due to the discovery of Cumarin (a powerful blood thinner) in Cassia Cinnamon, we no longer recommend this. Now, dosages of 500 - 1,000 mg/day are recommended. It may take a little longer to be effective, but some studies show that a lesser dosage can be just as effective long-term. This also reduces the need to gradually work up to your dosage.
Cinnamon can bring your blood sugar down when first getting used to it, so if at any time you get hypoglycemic symptoms (the "shakes", dizziness, headache, nausea/hunger, confusion, the sweats, irritability), treat it with a sweet drink followed by a healthy snack that is high in fibre and protein. You may need to either reduce your dosage for a week, or adjust your eating/exercise routine to better adjust to it.
Because PCOS is related to Insulin Resistance, you should look into a low-carb diet. I'm on South Beach (as are a number of us here with PCOS), because it is a low carb diet that can help you keep your blood sugar levels steady, thus reducing the effects of IR. South Beach really is the easiest diet to follow that I've ever been on.
Good luck hun!
