I'm going to sound very smug here, but don't mean to. The only symptom I had was that my periods stopped (at 55). I kept bracing myself for all the nasties that my friends were going through and nothing happened. I think at 63 I can safely say I'm out of the danger zone now!
I've always been a healthy eater, not much red meat, lots of fruit, veg and nuts, but also plenty of red wine and spicy food.
And I've always walked a lot, and did some running and yogalates in my fifties. Whether any of this helped, I couldn't say. I remember my mum and auntie suffering the hot sweats and mood swings, so I've been lucky.
