Skin blushing or flushing is a sudden reddening of the face, neck, or upper chest due to increased blood flow.

Blushing; Flushing; Red face

Blushing is a normal body response that may occur when you are embarrassed, angry, excited, or experiencing another strong emotion.

Flushing of the face may be associated with certain medical conditions, such as:

• High fever
• Menopause
• Rosacea (a chronic skin problem)
• Carcinoid syndrome (group of symptoms associated with carcinoid tumors, which are tumors of the small intestine, colon, appendix, and bronchial tubes in the lungs)

Other causes include:

• Alcohol use
• Certain medicines used to treat diabetes and high cholesterol
• Exercise
• Extreme emotions
• Hot or spicy foods
• Rapid changes in temperature or heat exposure

Try to avoid the things that cause your blushing. For example, you may need to avoid hot drinks, spicy foods, extreme temperatures, or bright sunlight.

Contact your health care provider if you have persistent flushing, particularly if you have other symptoms (such as diarrhea).

Your provider will perform a physical exam and may ask about your medical history and symptoms, including:

• Does the flushing affect the whole body or just the face?
• Do you have hot flashes?
• How often do you have flushing or blushing?
• Are episodes getting worse or more frequent?
• Is it worse after you drink alcohol?
• What other symptoms do you have? For example, do you have diarrhea, wheezing, hives, or difficulty breathing?
• Does it happen when you eat certain foods or exercise?

Treatment depends on the cause of your blushing or flushing. Your provider may recommend that you avoid things that trigger the condition.
