What can sickly pale skin mean?

Paleness is easier to judge in the lips, inside the eyelids, gums or palms than in skin affected by lighting or a natural complexion. Anaemia can make the skin, lips or inner eyelids look lighter because the blood carries less oxygen or there are fewer red blood cells. Iron deficiency, vitamin B12 deficiency, thalassaemia and sickle cell disease are different conditions that may contribute to anaemia. Sudden pallor can also occur with fainting, shock, cold or reduced circulation. Pale skin alone cannot identify the cause.

Arrange a medical assessment if the change persists, keeps returning or comes with tiredness, breathlessness, dizziness, palpitations, weight change or unusual bleeding. A clinician may examine your skin and inner eyelids and arrange blood tests. Do not start iron supplementation simply because you look pale; iron is useful for iron deficiency but may be unsuitable when another cause is present.

Seek emergency help for sudden marked pallor with fainting, confusion, cold clammy skin, severe breathlessness, chest pain, heavy bleeding or a rapidly worsening illness. These signs can reflect a serious circulation or blood problem and need immediate assessment.

Ask whether you need a blood count or tests for iron and vitamin B12, whether bleeding or diet could contribute, and which symptoms should prompt urgent review.
