"It is really just a consequence of environmental factors and ageing which cause the weight gain. But there's no doubt the new spare type many women complain of after menopause is real," Professor Davis said.

Abdominal fat deposits are closely linked to a variety of conditions, such as heart disease, so it is important that women try to avoid the build-up of fat in this area. "What this translates to in real terms is that women going through menopause should begin to try to control their weight before it becomes a problem," Professor Davis said.

"This means all women should be thoughtful about what they eat and for many, it means being more active each day. Oestrogen therapy can also help, but each woman is different, so when you hit menopause, it's very important to discuss your health with your doctor."

The study was part of a special edition of Climacteric prepared for World Menopause Day on 18 October.
