Hot flashes are one of the most commonly reported menopause symptoms in women. They can cause sudden warmth, sweating, and discomfort, especially on the face and neck. Tap to know what causes hot flashes after menopause in women.

Oestrogen Drop

The primary cause of hot flashes is reduction in oestrogen levels after menopause, which affects the body’s temperature regulation.

Hypothalamus Disruption

Hormonal changes can confuse the hypothalamus, a part of the brain that regulates body temperature, causing it to react as if the body is overheating.

Blood Vessel Expansion

The body tries to release heat by widening blood vessels near the skin’s surface, causing a flushed appearance and sweating.

Increased Sensitivity

Postmenopausal women may become more sensitive to heat, stress, spicy foods, and caffeine, which can trigger hot flashes.

Slower Metabolism

Menopause can slow down the metabolism, disrupting the internal heat regulation and leading to more frequent hot flashes.

Emotional Stress

Anxiety and mood swings are common during menopause, and may contribute to more severe hot flashes.

Information Credits

According to PubMed, hormonal fluctuations, slow metabolism, and other reasons are responsible for hot flashes. It is advisable to consult a gynaecologist for personalised suggestions.
