The menopause is when a woman stops having periods and is no longer able to get naturally pregnant. Symptoms include hot flushes, night sweats, reduced sex drive and a low mood.
According to the NHS, the menopause normally occurs between 45 to 55, however in around 1% of women in the UK, this can happen before the age of 40.
Here are seven celebrity women talking about their experiences.

"It was at the point that I felt like my life was falling apart around me that I started to ask what could be going on internally, and friends suggested it might be hormonal…I was used to being able to balance a lot of things, and all of a sudden I felt like I could handle nothing. I felt completely overwhelmed.
"Peri-menopause and menopause should be treated as the rites of passage that they are. If not celebrated, then at least accepted and acknowledged and honored."
"I will not be able to have any more children, and I expect some physical changes. But I feel at ease with whatever will come, not because I am strong but because this is a part of life. It is nothing to be feared."

"It is fairly brutal and you go through all the accompanying side effects: hot flushes, weight gain, a sense of mourning for lost youth, sexiness and somehow the point in anything. I became depressed, which I ended up getting help with.”

"It is a nightmare, an absolute nightmare. It's horrible. And I don't look like that kind of person, you don't put menopause on top of my head, it doesn't associate with me."

"I still get hot flushes. That’s fifteen bloody years. Still, it’s nothing like I did then. Ripping off your nightie and Grant [her husband] thinking it’s something else! No – don’t get any ideas!”

"Literally one moment you’re fine, and then another, you feel like you’re in a vat of boiling water, and you feel like the rug has been pulled out from underneath you.
What I would say, which I’ve said to myself and to girlfriends who’ve also experienced hot flashes, in particular, is that change is part of being human. We evolve and should not fear that change. You're not alone. I feel that part of living this long is experiencing this, so I’m trying to turn it into a very positive thing for myself, which it has been, in the sense of acceptance and tolerance and education about this time of life."

"How hideous for women of our mothers' generation, because - while me and my girlfriends will talk about everything under the sun, including the menopause - it was something they didn't discuss. They must have felt so lonely and embarrassed all the time.
"For me, it's tailing off now. But I can still suddenly go that awful colour when I'm talking to somebody and sweat beads will break out on my upper lip. You're acutely aware of it, even if they're not."
