Pallor is a key indicator of anemia. Pallor or paleness may be caused due to the decreased blood supply to the skin. Paleness is related to blood flow in the skin rather than the deposition of melanin in the skin. Pallor can also be a sign of:
- Iron-deficiency anemia
- Albinism (a rare group of genetic disorders that cause the skin, hair, or eyes to have little or no color)
- Aplastic anemia (a condition in which the body stops producing enough new blood cells)
- Anorexia (an eating disorder)
- Arterial occlusion (a circulatory condition in which blocked or narrowed blood vessels reduce blood flow to the limbs)
- Autoimmune hemolytic anemia (a rare disorder in which the person’s immune system attacks their red blood cells)
- Bleeding
- Chemical poisoning
- Chronic diseases including infection and cancer
- Diamond–Blackfan syndrome (a condition that primarily affects the bone marrow)
- Disseminated intravascular coagulation (DIC) (a condition affecting the blood’s ability to clot and stop bleeding)
- Fainting
- Frostbite
- Fanconi anemia (a rare inherited disorder that mainly affects the bone marrow)
- Fear or panic reaction
- Folic acid deficiency
- Heart disease
- Hypothyroidism
- Lack of sun exposure
- Low environmental temperature
- Low blood sugar
- Kidney failure
- Malnutrition
- Medication side effects
- Motion sickness
- Problems with the circulatory system
- Respiratory failure
- Severe trauma
- Shock
- Sleep deprivation
- Tuberculosis
- Thrombotic thrombocytopenic purpura (TTP) (a blood disorder that results in blood clots forming in small blood vessels throughout the body)
- Transient erythroblastopenia of childhood (TEC) (slowly developing anemia that occurs in early childhood)
- Tuberculosis
- Vitamin B12 deficiency
What is pallor?
Pallor, derived from the Latin pallere, meaning “to be pale,” is a medical sign related to several health conditions. Paleness of the skin indicates an atypical lightening of the skin or mucous membranes. Pale skin may occur all over the body or be localized to one area. Pallor is most easily seen on the face, inner lining of the eyelids (palpebral conjunctiva), inner lining of the mouth (oral mucosa), and nails. Pallor seen in these areas may indicate a serious condition:
- Inner surface or lining of the eyelids
- Inside of the mouth
- The surface of the tongue
- Lips
- Palms
Pallor and albinism shouldn’t be confused, as the latter have a loss of skin pigmentation (melanin).
How does the physician diagnose pallor?
The physician will perform a physical examination of the patient and ask about any symptoms. They may order the following tests, which include:
- CBC (complete blood count): This test helps measure blood cell counts and hemoglobin to identify anemia or infection.
- Blood differential test: This test measures the percentage of each type of white blood cells in your body.
- Thyroid function tests: A low functioning of the thyroid can cause anemia.
- Colonoscopy: This is done to check for bleeding in the large intestine.
- Kidney function tests: Kidney failure causes anemia. Hence, kidney function tests are essential to check the overall functioning of the kidney.
- Extremity arteriography: It is used to see arteries in the hands, arms, feet, or legs.

Anemia: Common Causes, Symptoms, Types, and Treatment
Anemia is a disease marked by low numbers of red blood cells. Low iron deficiency or underlying disease, like cancer, may be to blame. Treatment can resolve anemia.
Anemia
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased. There are several types of anemia such as iron deficiency anemia (the most common type), sickle cell anemia, vitamin B12 anemia, pernicious anemia, and aplastic anemia. Symptoms of anemia may include fatigue, malaise, hair loss, palpitations, menstruation, and medications. Treatment for anemia includes treating the underlying cause for the condition. Iron supplements, vitamin B12 injections, and certain medications may also be necessary.
Common Medical Abbreviations & Terms
Doctors, pharmacists, and other health-care professionals use abbreviations, acronyms, and other terminology for instructions and information in regard to a patient's health condition, prescription drugs they are to take, or medical procedures that have been ordered. There is no approved this list of common medical abbreviations, acronyms, and terminology used by doctors and other health- care professionals. You can use this list of medical abbreviations and acronyms written by our doctors the next time you can't understand what is on your prescription package, blood test results, or medical procedure orders. Examples include:
- ANED: Alive no evidence of disease. The patient arrived in the ER alive with no evidence of disease.

How Does Anemia Affect Pregnancy?
Anemia is a condition in which your body doesn't make enough red blood cells. The most common type is iron-deficiency anemia which 50% of women develop during pregnancy.
Pernicious Anemia
Pernicious anemia is a blood disorder in which the body does not make enough red blood cells due to a lack of vitamin B12 in the blood. Pernicious anemia can develop from a lack of a protein that helps the body absorb vitamin B12, not getting enough B12 in the diet, and certain intestinal conditions that interfere with the absorption of vitamin B12 such as Crohn's disease, celiac sprue, or ulcerative colitis. There is no cure for pernicious anemia, thus treatment is life-long.Pernicious Anemia Picture
Pernicious anemia is a disease where large, immature, nucleated cells (megaloblasts, which are forerunners of red blood cells) circulate in the blood, and do not function as blood cells; it is a disease caused by impaired uptake of vitamin B-12 due to the lack of intrinsic factor (IF) in the gastric mucosa. It was termed "pernicious" because before it was learned that vitamin B-12 could treat the anemia, most people that developed the disease died from it.
Sickle Cell Disease (Anemia)
Sickle cell anemia (sickle cell disease), a blood disease that shortens life expectancy, is caused by inherited abnormal hemoglobin. Symptoms of sickle cell anemia may include bacterial infections, painful swelling of the hands and feet, fever, leg ulcers, fatigue, anemia, eye damage, and lung and heart injury. Treatment for sickle cell anemia aims to manage and prevent the worst manifestations of the disease and focuses on therapies that block red blood cells from stacking together, which can lead to tissue and organ damage and pain.
How Do You Fix Anemia?
Anemia describes a condition in which you have a low red blood cell count and low hemoglobin levels. This is a serious condition as red blood cells and hemoglobin carry oxygen to all your cells, allowing them to burn energy. If you’re anemic, you’ll likely feel fatigued and short of breath, lacking physical stamina. You may have heart problems and appear pale. Anemia is often a symptom of some other disease or condition, so treatment varies widely depending on the root cause.
