Skin flushing occurs because of increased blood flow, which may be due to menopause and certain conditions or medications. Depending on the cause, there may be several options to help treat or prevent skin flushing.
Sudden redness or discoloration in your face or upper body can be concerning, especially if you aren’t experiencing other unusual symptoms. But the onset of skin flushing, or blushing, isn’t necessarily a serious problem, especially if it’s not a recurring issue.
How do you know whether skin flushing or blushing is a sign of a more serious medical concern? Learn more about the most common causes of this sudden skin discoloration and when to contact a doctor.
Skin flushing, or blushing, happens due to increased blood flow. Whenever more blood flows to an area of skin, such as your cheeks, the blood vessels enlarge to compensate. This enlargement is what gives skin the “flushed” effect.
Due to this increased blood flow, you may feel warmth around your neck, upper chest, or face.
On lighter skin tones, this flushing may result in patches of visible reddening. On darker skin tones, flushing may not result in reddening of the skin but may instead cause discoloration or darkening of the affected area.
Flushed skin is a common physical response to:
- other extreme emotional states
Facial flushing is usually more of a social worry than a medical concern.
However, flushing can result from an underlying medical issue, such as Cushing syndrome or a niacin overdose. Check with a healthcare professional if you have recurring skin flushing or blushing.
The symptoms associated with skin flushing may vary due to its underlying cause. Some may be temporary or manageable at home, while others may relate to more severe conditions that require medical attention.
In general, the many causes of skin flushing or blushing tend to cause the following:
- skin discoloration in your face, neck, chest, or upper trunk
- feelings of warmth or sweating in the affected areas
- rapid onset of the above symptoms
Many different conditions can cause skin flushing, according to the National Health Service (NHS). Here are some possible causes.
Menopause occurs when hormone production in the ovaries decreases and menstrual periods stop permanently. The symptoms are primarily related to lower production of the sex hormones estrogen and progesterone.
Other symptoms of menopause may include:
- hot flashes
- vaginal dryness and pain with intercourse
- frequent urination or urinary incontinence
- decreased libido
- mood swings
- genitourinary syndrome of menopause (GSM)
Hot flashes may lead to skin flushing and blushing, particularly in the face and chest areas.
Menopause symptoms can last for months or years, depending on the person. Hot flashes may last for 14 years after menopause, according to the
This chronic skin disease goes through cycles of fading and relapse. Relapses may be caused by:
- eating spicy foods
- alcoholic beverages
- the intestinal bacteria Helicobacter pylori
Four subtypes of rosacea encompass a wide variety of symptoms. Other common symptoms include:
- facial flushing
- raised skin bumps
- facial skin discoloration
- skin dryness
- skin sensitivity
While the cause of rosacea is unknown, inflammation of the blood vessels from stress, spicy foods, and hot temperatures may worsen the condition. The American Academy of Dermatology (AAD) says that fair-skinned women between the ages of 30 and 50 are the most susceptible.
Erythema infectiosum (“fifth disease”)
Fifth disease is the result of a virus. It can cause a rash on the cheeks, arms, and legs.
It’s commonly spread among elementary school children and usually results in mild flu-like symptoms. The
Other symptoms include:
- low fever
- sore throat
- runny nose
This type of anxiety disorder causes people to avoid places and situations that might make them feel trapped, helpless, or embarrassed.
- fear of leaving the home for extended periods
- fear of being alone in social situations
- fear of being in places that would be difficult to escape
As anxiety increases, the NHS says that your skin may flush and feel hot to the touch.
Other symptoms may include:
- feelings of fear or dread
- increased heart rate
- chest pain
- increased sweating
Scarlet fever occurs at the same time as or right after a strep throat infection.
Scarlet fever results in a discolored skin rash all over the body. According to a 2015 study, the rash typically starts on the upper trunk but does not spread to the palms or soles of the feet.
This rash often includes tiny bumps that make it feel like “sandpaper.” Another symptom is a bright red tongue.
This condition occurs when the thyroid gland makes too much thyroid hormone, leading to an excessively high metabolic rate.
Hyperthyroidism results from a variety of conditions, including:
- an autoimmune disease called Graves’ disease
- nodules or tumors
- excess iodine
- inflammation of the thyroid (thyroiditis)
The AAD says that hyperthyroidism can cause facial skin flushing and discoloration in the palms. According to the
- rapid heart rate
- elevated blood pressure
- hand tremors
- low tolerance for heat
- weight loss
- difficulty sleeping
- nausea and vomiting
- menstrual irregularities
Pyelonephritis is a serious infection located in the upper parts of the urinary tract, including the kidneys.
Common symptoms include:
- body aches
- pain in the abdomen, groin, or back
According to a
Cloudy or bloody urine, pain with urination, and frequent urination may also occur.
Cluster headache is a rare headache disorder that can affect up to 0.1% of the population. People with this disorder can experience painful headaches that last for 15 to 180 minutes that may occur once every other day to up to 8 times per day, according to
Cluster headaches can cause constant and deep burning or piercing pain on one side of the head. They can result in facial flushing.
You may feel this pain behind the eyes. Pain may spread to other areas on the same side, including the:
Other symptoms of cluster headaches include:
- constricted pupils
- excessive tearing
- eye redness
- sensitivity to light
- swelling under or around one or both of your eyes
- a runny nose or stuffy nose
Yellow fever is a serious, potentially deadly, flu-like viral disease that mosquitoes spread. It’s most prevalent in certain parts of Africa and South America.
Vaccination can help prevent yellow fever. According to National Organization for Rare Disorders (NORD), you can expect to be immune 10 days after getting the vaccine, with protective effects lasting at least 10 years.
Initial symptoms of the infection are similar to those of the influenza virus, including:
- flushed face
- body aches
- loss of appetite
Autonomic dysreflexia (autonomic hyperreflexia)
With this condition, your involuntary nervous system overreacts to external or bodily stimuli.
Autonomic dysreflexia is a medical emergency and may require urgent attention.
Along with flushing of the skin, symptoms include:
- irregular or racing heartbeat
- high blood pressure
- profuse sweating
- dilated pupils
Cushing syndrome occurs due to unusually high levels of the stress hormone cortisol in the blood. The
Other symptoms include:
- fatty deposits, especially in the midsection, face, and back
- muscle weakness
- glucose intolerance
- high blood pressure
People with Cushing syndrome may also have thinning skin that bruises easily and heals slowly and purple stretch marks. These may appear on the
Niacin flush is a common and harmless side effect of taking high doses of supplemental niacin (vitamin B3).
Alongside facial flushing, you may experience an itching or burning sensation. According to the
Tolerance and a decrease in symptoms may occur over time.
There are many specific causes of facial flushing, such as heightened emotional states or eating spicy foods. Several medications and medical conditions may also cause skin flushing.
The AAD says that several medications can cause flushing as a side effect. These include drugs that treat inflammation, high blood pressure, anxiety, and other conditions. These medications may include:
- corticotropin-releasing hormone
- doxorubicin (Lipodox, Doxil)
- vasodilators, such as nitroglycerin (Rectiv, Nitro-Time, Nitrolingual)
- calcium channel blockers
- morphine (Arymo ER, MorphaBond ER, MS Contin) and other opiates
- amyl nitrite and butyl nitrite
- cholinergic drugs, such as metrifonate, and anthelmintic drugs
- bromocriptine (Parlodel, Cycloset)
- thyrotropin-releasing hormone
- tamoxifen (Soltamox)
- cyproterone acetate (not available in the U.S.)
- oral triamcinolone
- cyclosporine (Sandimmune, Neoral, Gengraf)
- rifampin (Rifadin)
- sildenafil citrate (Viagra, Revatio)
Talk with a doctor if you think any prescription or over-the-counter medication may contribute to your flushing symptoms. Never stop taking any medications without discussing them with a medical professional first.
Warning: Stopping medication
Never stop taking a prescribed medication without doctor guidance. Dangerous side effects can occur, depending on the medication.
According to the AAD, consuming spicy foods, such as peppers or products derived from the Capsicum family of plants, can cause sudden skin discoloration and sweat on the face or neck. These include:
- cayenne peppers
- chili peppers
- red peppers
Eating these foods may raise your body temperature, increasing blood flow and causing facial discoloration. Handling these types of foods can also cause skin irritation.
Extreme emotions, such as stress, anger, and embarrassment, can cause flushing in the face.
These emotions can also coincide with an acute increase in blood pressure. Still, high blood pressure itself is not a cause of flushing, according to the
Other risk factors
Other possible causes of facial blushing include:
- drinking alcohol, especially red wine
- hot beverages
- high temperatures
- cold weather
- inflammatory conditions
- certain cosmetics and skin products
- contact dermatitis
Treating any underlying conditions causing your flushing is often the best remedy. For example, the NHS says that a doctor may recommend medications or a course of psychotherapy to reduce feelings of anxiety if that’s the cause.
However, home health options include avoiding specific triggers, such as:
- spicy foods
- hot beverages
- bright sunlight
- extreme cold or heat
Removing yourself from high-stress situations may also help prevent flushing.
It’s important to get immediate medical care for unusual symptoms of flushing. Also, contact a doctor if you’re having recurring episodes, since flushing can be linked to serious medical conditions.
A medical exam and history will help supply the required information for a healthcare professional to make a diagnosis. Be sure to mention other co-occurring symptoms, such as diarrhea, shallow breathing, or hives, so the doctor may evaluate them.
If the doctor finds your symptoms are emotionally based, they may refer you to a psychotherapist. These professionals can teach you skills to help you cope with extreme emotional events and prevent flushing.
Flushing does not commonly result in serious medical problems but may cause feelings of embarrassment or social anxiety.
However, in some instances, a serious condition can be the underlying cause of flushing. Without treatment, the underlying condition can lead to complications.
There is no definitive method for preventing flushing. However, you can do some things to reduce the risk of these episodes:
- Limit the amount of alcohol you drink: Some people are more prone to redness and warmth on the skin after drinking alcohol. In these people, an enzyme that helps break down alcohol is inactive, resulting in alcohol intolerance.
- Limit your handling and eating of spicy foods: You may benefit from avoiding foods derived from the Capsicum genus.
- Try to avoid extreme temperatures: Extreme temperatures and excessive bright sunlight may all result in skin flushing.
- Limit your niacin intake: The daily allowance recommended by the
NIHis 14 to 16 milligrams for adults, unless a healthcare professional tells you differently.
- Employ coping skills: Regulating extreme emotions such as anxiety may help you to reduce the frequency of your blushing.
Skin flushing or blushing occurs when blood vessels near the skin surface enlarge to accommodate an increased blood flow.
When this happens, you may experience redness or other skin discoloration, as well as feelings of warmth in the affected areas.
Skin flushing can result from an underlying condition such as rosacea and hyperthyroidism. Or you may experience it during periods of extreme emotions, such as stress or embarrassment.
Typically, the condition is not a medical emergency and will resolve with time. However, if you experience repeated, severe flushes, contact your doctor for a full diagnosis.
