What should you know about skin too pale?

Paleness may be easier to notice on the face, lips, inside the eyelids, gums, or palms, depending on your natural skin tone. Cold, fright, temporary reduced blood flow, dehydration, or recent illness can change appearance. A clinician may consider [Anaemia](/conditions/anaemia/), in which the blood carries less oxygen than usual, especially when pallor occurs with tiredness, breathlessness, dizziness, headaches, or a fast heartbeat.

Iron deficiency is one possible cause, while vitamin B12 deficiency, inherited blood conditions such as [Thalassaemia](/conditions/thalassaemia/) or [Sickle Cell Disease](/conditions/sickle-cell-disease/), and other illnesses can also affect colour or energy. Pale skin alone cannot identify the cause.

Compare the change with recent photographs or your usual appearance, and note when it began. Record associated symptoms, changes in menstrual bleeding, dietary restrictions, digestive symptoms, recent illness, and medicines. Arrange a routine appointment if the change persists or keeps returning; a clinician may examine you and request blood tests.

Do not start iron tablets just because you look pale. Treatment should match the cause; [Iron Supplementation](/treatments/medical-management/iron-supplementation/) can be useful when iron deficiency is confirmed or strongly suspected, but excess iron can be harmful and may delay the right diagnosis.

Seek urgent help for sudden marked paleness with fainting, confusion, severe breathlessness, chest pain, heavy bleeding, black stools, or a racing heartbeat. Emergency assessment is also needed if pale or grey lips occur with difficulty breathing or a person is difficult to wake.

Prompt review is sensible when pallor follows ongoing bleeding, occurs with worsening weakness, or affects a child who is not feeding or behaving normally. Do not let a familiar diagnosis such as anaemia mask a new or rapidly changing symptom.

What could explain the colour change, which blood tests are appropriate, and could bleeding or diet be contributing? Ask whether you need assessment for iron deficiency, vitamin B12 deficiency, or an inherited blood condition, and how soon results should be reviewed.
