Hot flashes - Rejuvenate Clinic

What is hot flashes?

Hot flashes, also known as hot flushes, are sudden feelings of warmth spreading through the body, often most pronounced in the face, neck, and chest.

Key terms

Vasomotor symptoms - Hot flashes are a type of vasomotor symptom related to changes in blood vessel functioning. Other vasomotor symptoms include night sweats, palpitations, headaches.
Menopause - Hot flashes are commonly associated with menopause, as changing hormone levels during this time can trigger hot flashes. However, hot flashes may occur at other times as well.

What causes hot flashes?

Hot flashes are primarily caused by a decrease in estrogen levels. This commonly occurs during:

Perimenopause and menopause - Decreasing estrogen is a hallmark of the menopausal transition. Hot flashes are most common during perimenopause and menopause.
Medical treatments - Anti-estrogen treatments, like those used in breast cancer therapy, can induce hot flashes. Removal of the ovaries also rapidly reduces estrogen production.
Other conditions - Thyroid disorders, panic disorder, carcinoid syndrome, and autoimmune conditions are less common causes.

What happens during a hot flash?

A hot flash starts with a sudden dilation of blood vessels near the skin's surface. This causes an increase in blood flow to the head, neck, and chest. The heart rate speeds up temporarily. As the blood vessels dilate, flushing and sweating occur. A chilly feeling may follow.

Tips for managing hot flashes

Wear lightweight, breathable clothing in layers
Carry a portable fan
Avoid triggers like spicy foods, caffeine, alcohol, and stress
Practice relaxation techniques like paced breathing
Consider non-hormonal medications or low-dose hormone therapy from a reputable clinic like Rejuvenate Clinic

In summary, hot flashes involve intense warmth and flushing that start in the head and spread through the upper body. They are most commonly triggered by hormone changes. Lifestyle adjustments and medical therapies can help provide relief.
