Why does G6PD deficiency cause pale skin?

G6PD is an enzyme that helps red blood cells handle oxidative stress. Without enough of it, certain triggers can damage these cells and cause haemolysis, meaning the cells break apart earlier than expected. A fall in circulating red blood cells can cause anaemia, which may make the skin, lips, gums, or inside of the lower eyelids look paler. Pale Skin is a common presentation of G6PD Deficiency, but pale skin also has many other possible causes.

If you know you have G6PD deficiency, keep a record of medicines, foods, or illnesses that have previously brought on symptoms. Tell any clinician or pharmacist about the condition before starting a medicine. A clinician can assess pallor with an examination and blood tests that check red-cell and haemoglobin levels. Rest, fluids, and prompt assessment may be helpful during an illness, but the right plan depends on the cause and severity of red-cell breakdown.

Arrange urgent medical assessment for new or worsening paleness with shortness of breath, chest discomfort, fainting, marked weakness, a racing heartbeat, dark urine, or yellowing of the eyes or skin. Seek prompt care after a suspected trigger if you have G6PD deficiency, especially when symptoms develop quickly. Emergency care is appropriate if breathing is difficult, you collapse, or you feel severely unwell.

Ask whether your symptoms suggest active haemolysis, which blood tests are needed, and whether a recent medicine, infection, or food could be relevant. It can also help to ask which products to avoid and when repeat testing is needed.
