If your cycle has been longer than 32 days for 3 months in a row you could have something called Oligomenorrhea. It's not a condition it's just the posh name for having long cycles. It could be totally normal for you but if it's not, it's a good idea to get it investigated. Usually long periods are a sign you're not ovulating (having an anovulatory cycle in doctor-speak). If you're around 40 this is probably happening because you're starting to transition into perimenopause.
PCOS can be a terrible condition. It can make you infertile, overweight, spotty, fatigued and hairy-er. For many women suffering with it they feel depressed and un-feminine. Here's an excerpt from my free guide to PCOS.
Most will think that balancing blood sugar is just something diabetics do. Few realise that it's crucial for regulating female hormones as well.
When our blood sugar dramatically rises and drops throughout the day we release insulin to try and compensate. But if we do this for a long time gradually we build up a tolerance to the insulin and this throws other hormones like oestrogen out of whack. This happens in polycystic ovarian syndrome (PCOS). A woman with PCOS may experience male pattern hair growth (hirsutism), irregular periods and infertility. They often struggle to maintain a healthy weight too.
