Facial Flushing

Facial Redness and Heat

Mild severity35% reported by patientsICD-10: R23.2

Summary

Sudden redness and warmth of the face caused by increased blood flow, ranging from benign triggers like embarrassment to hormonal changes or rare conditions.

What is it?

Facial flushing results from dilation of blood vessels in the face. It is extremely common and usually benign — caused by emotional reactions, heat, alcohol, spicy foods, or exercise. Persistent or recurrent flushing warrants investigation for rosacea, carcinoid tumor, pheochromocytoma, mastocytosis, and menopause (hot flashes). Medications including niacin, calcium channel blockers, and vasodilators commonly cause flushing. Flushing with diarrhea, wheezing, and abdominal cramping may indicate carcinoid syndrome.

What you can do
