Postmenopausal hormonal changes that cause hot flashes and mood swings also increase the risk of heart disease and stroke, according to experts.

"Many women younger than 50 have not yet gone through menopause and still have high levels of the female hormone estrogen in their blood, which is thought to help protect the heart," explained Dr. Vera Rigolin of the Center for Women’s Cardiovascular Health at Northwestern Memorial Hospital. "After menopause, however, the levels of estrogen in a woman’s body drop significantly and can contribute to the higher risks of cardiovascular disease."

Weight gain often associated with menopausal hormonal changes can also increase health risks. Women may also have a harder time losing weight, which can contribute to high blood pressure, diabetes, and high cholesterol – all risk factors that can lead to heart attack and stroke.

Adopting a healthy lifestyle is the best way to lower the risk of heart attack and stroke, according to healthcare experts.

"If you are a smoker, quit immediately and avoid second hand smoke. Eat a diet rich in fruits and vegetables and exercise at least three times per week to maintain a healthy body weight," said Rigolin.

She also recommends that women have their blood pressure, blood sugar and cholesterol levels checked annually.
