Hello,
I was diagnosed with PCOS last year. My endocrinologist told me that PCOS is directly correlated with obesity. However, losing the weight does not automatically mean the PCOS will go away. But, she did tell me that with weight loss the adverse symptoms will improve (excessive hair growth, irregular menstruals etc.) Also, weight loss will decrease and often eliminate the cysts in your ovaries. I am praying that my PCOS is reversed or at the very least that my cycle starts to regulate.
A side note:: (for those with irregular cycles) A friend of mine would sometimes go months without having a cycle. She lost 80lbs (naturally- not through surgery) and now her cycle is normal. So that is proof that loosing weight can help your body get back on track. But, from what I was told, there is no guarantee.
Also, you should probably see an endocrinologist who specializes in PCOS. Only because my OB/GYN told me different things in regards to PCOS and my endocrinologist flat out told me that OB/GYN's have different perspectives on PCOS. However, they are not specialists on the subject matter where as endocrinologists are. Just food for thought!
