Dr Rebecca Lewis talks to presenter Sameena Ali-Khan about the menopause
Menopause happens when a women has gone 12 months without a menstrual period, it can have a big impact on a persons life, including relationships and work.
Dr Rebecca Lewis, who is a menopause expert, has spoken to ITV News Central saying there are useful tools which can help to track symptoms.
She said: "It is difficult sometimes to diagnose on the perimenopause.
"I'd always recommend people to look at the 'free balance app', because you can track your symptoms and get a health report which immediately the GP can see at a glance that these symptoms might be due to a lack of female hormones due to the menopause.
"There's a lack of education (on hormone replacement therapy - HRT) in the healthcare professionals and understanding how important HRT is and how important to know how safe HRT is for women, and women to understand their symptoms and know it's due to menopause."
