How does anemia affect your lips?

Anemia is a condition characterized by a decrease in the number or size of red blood cells in the body. Red blood cells carry oxygen from the lungs to tissues throughout the body. When someone has anemia, their blood cannot deliver enough oxygen to the body’s cells. This can cause a variety of symptoms, including fatigue, weakness, dizziness, headaches, and shortness of breath. Anemia can also affect the appearance and health of your lips.

What causes anemia?

There are many different causes of anemia, including:

  • Iron deficiency – This is the most common cause of anemia. Iron is an essential component of hemoglobin, the protein in red blood cells that carries oxygen. An iron deficiency can develop due to inadequate iron absorption or intake, blood loss, or increased iron requirements during growth or pregnancy.
  • Vitamin deficiency – Vitamins like folate (B9), B12 and vitamin C are needed to produce red blood cells. A deficiency in these vitamins can lead to decreased red blood cell production.
  • Chronic disease – Diseases like cancer, kidney failure, and rheumatoid arthritis can impair the body’s ability to produce red blood cells.
  • Inherited disorders – Conditions like sickle cell anemia and thalassemia interfere with hemoglobin production and cause anemia.
  • Excess red blood cell destruction – Some conditions cause the premature destruction of red blood cells, including autoimmune disorders, enlarged spleen, and use of certain medications.

How does anemia affect your lips?

Anemia can cause pale, thinning lips for several reasons:

Decreased blood circulation

With anemia, there is less hemoglobin to carry oxygen throughout the body. This means the lips (and other tissues) receive less blood circulation. The decreased blood flow causes the lips to appear paler than normal. The lips may also take on a bluish, purplish, or grayish hue due to oxygen deprivation.

Nutrient deficiencies

Many nutrients are essential for healthy lips, including iron, folate, vitamin B12, and vitamin C. Deficiencies in these nutrients due to anemia can contribute to pale, unhealthy lips. Iron deficiency anemia, in particular, is strongly associated with pale lips.


Fatigue and weakness caused by anemia can sometimes lead to poor fluid intake and dehydration. Dehydration exacerbates anemia symptoms and dries out the lips, causing them to appear pale and thin.

Angular cheilitis

People with anemia are more prone to developing angular cheilitis, which is inflammation, scaling, and cracking at the corners of the mouth. Angular cheilitis can cause lips to appear pale, dry, and irritated. The condition is often triggered by nutritional deficiencies associated with anemia.

Other lip changes

In addition to paleness and thinning, some other lip changes may occur with anemia:

  • Dryness – Anemia can cause dry, flaky lips due to poor circulation and nutrient deficiencies.
  • Cracking – Severely dry lips are more prone to cracking, peeling, and splitting.
  • Swelling – In rare cases, the lips may swell due to a buildup of fluid caused by anemia.
  • Tingling or numbness – Some people with anemia experience a loss of sensation in their lips.
  • Cold sores – The stress of anemia on the body can trigger cold sores (fever blisters) on or around the lips.

Who is most at risk?

Those most likely to develop pale, unhealthy lips from anemia include:

  • Women – Due to blood loss from menstruation and higher iron needs during pregnancy
  • Young children and teens – High iron requirements to support growth and development
  • Vegans and vegetarians – May have inadequate iron intake due to limited animal products
  • Frequent blood donors – At risk for low iron stores
  • People with chronic diseases like cancer, kidney failure, and rheumatoid arthritis
  • Those with gastrointestinal disorders that impair nutrient absorption

When to see a doctor

You should make an appointment with your doctor if you notice any unexplained lip changes, including prolonged paleness, dryness, cracking, swelling, tingling, or cold sores. Let your doctor know if you experience any other symptoms of anemia like chronic fatigue, weakness, dizziness, or headaches. Diagnostic blood tests can help determine if anemia or other nutritional deficiencies are causing changes to your lips. Prompt treatment of the underlying condition can help restore healthy lips.


Treating the cause of anemia is key to improving lip appearance and texture. Your doctor will recommend treatment options based on the type of anemia:

  • Iron supplements – For iron deficiency anemia
  • Vitamin supplements – Such as folic acid and B12 for deficiency anemias
  • Underlying condition management – Treating chronic diseases and disorders leading to anemia
  • Medications – Drug therapies may help some forms of anemia
  • Diet modification – Increasing iron, folate, B12 foods
  • Blood transfusions – For severe or symptomatic cases unresponsive to other therapies

In addition to medical treatment for anemia, you can help improve the appearance of your lips by:

  • Drinking plenty of fluids
  • Using lip balm and moisturizer
  • Avoiding licking or biting lips
  • Applying sunscreen with SPF
  • Taking B-complex vitamins
  • Consuming more iron-rich foods like meat, eggs, leafy greens, nuts, and beans

With proper treatment, the lip changes caused by anemia are usually reversible. Lips typically regain their normal pinkish color and texture after anemia improves. However, it may take weeks to months to see full resolution of lip symptoms after starting treatment. Talk to your doctor if your lips remain very pale or unhealthy despite correcting your anemia. Other nutritional deficiencies may need to be addressed.


Anemia can significantly impact the appearance and health of lips. The decreased oxygenation and circulation associated with anemia causes lips to appear paler and thinner than normal. Nutrient deficiencies contributing to anemia may also dry out and damage the lips. People with iron, folate, B12, or vitamin C deficiency anemias are most likely to develop pale, unhealthy looking lips. Treating the underlying type of anemia, staying hydrated, using lip moisturizers, and getting adequate nutrition can help restore normal, healthy lips. Lips can be an early indicator of a possible anemia in some cases. Pay attention to any unexplained changes in lip appearance and be sure to discuss symptoms with your doctor.
