Experts reveal link between menopausal hot flashes and cardiovascular distress

Medical experts are urging women to reconsider their perception of hot flashes, warning that these common menopausal symptoms may signal underlying cardiovascular distress.

Dr Alessia Roehnelt, a New Jersey-based endocrinologist, highlighted on 18 March that the sudden sensations of heat and sweating frequently normalised during menopause warrant serious medical attention.

Contrary to the belief that they are merely a hormonal inconvenience, these episodes may reflect the health of the heart and arteries.

“Hot flashes are not just something uncomfortable happening to you. They actually can be a sign of what's going on in your cardiovascular system,” Dr Roehnelt cautioned.

The physiological process, known as a vasomotor response, involves the dilation of blood vessels, an increased heart rate, and activation of the nervous system.

Research suggests that frequent flashes are often early indicators of endothelial dysfunction, a condition where narrowed arteries increase the risk of heart disease.

The physiological impact and treatment

• Vasomotor response: “During a hot flash, your blood vessels dilate, your heart rate increases, and your nervous system activates. This is called a vasomotor response. Everything is involved, blood vessels, nervous system,” Dr Roehnelt noted.
• Interconnected risks: Poor vascular function can trigger a cycle of weight gain, insulin resistance, and disrupted sleep.
• Clinical approaches: Management typically involves a full cardiovascular risk assessment or hormone replacement therapy.

Patients are encouraged to avoid 'pushing through' the discomfort. Instead, an open dialogue with a clinician is essential to address potential risks like high cholesterol or blood sugar.
