What do I need to know about PCOS? I just got diagnosed and my doctor did not give me sufficient information about it. I was told it was not common in thin girls (I’m 110lbs) & that I should cut down on carbs. My blood work came back normal. I asked her if my pcos is the reason why I’m bloated like 24/7 and she said bloating is not a symptom and she wasn’t sure why I was experiencing that. I was diagnosed with pcos because it came up in my ultrasound and my periods are more than 35 days apart.
