Pale and grey skin: what it may signal

Pale skin looks lighter than a person’s usual tone; grey skin may look ashen, dull or unusually washed out. Lighting, cold temperature and natural skin variation can affect appearance, so compare with the person’s usual colour and check the lips, tongue or nail beds. Anaemia can present with paleness, and iron deficiency anaemia or vitamin B12 deficiency may be involved. Sickle Cell Disease and Thalassaemia can affect blood cells and oxygen delivery. These conditions are possibilities, not conclusions from a colour change.

Record whether the change came suddenly or gradually and whether the person has dizziness, pain, fever, bleeding, weakness or altered alertness. A clinician may need to examine circulation and order blood tests.

Move the person away from cold or heat, let them rest safely and keep observing their breathing and alertness. If they feel faint, help them lie down. Offer water only when they are fully awake and can swallow normally. Arrange a medical review for persistent, recurrent or unexplained paleness, particularly with tiredness, headaches, breathlessness or bleeding. Do not self-treat with iron before the cause has been assessed.

Call emergency services if the colour change is sudden and the person is confused, faint, difficult to wake, struggling to breathe, has chest pain, severe weakness, blue lips or heavy bleeding. Seek prompt assessment after injury, suspected poisoning or a serious infection. Do not leave an unusually grey or clammy person alone while waiting for help.

Ask whether the colour suggests a circulation or blood problem, which tests are suitable, and whether diet, menstrual bleeding, medicines or family history matter. Ask what changes require emergency care.
