Blue or grey skin or lips, known as cyanosis, occur when there’s insufficient oxygen in your blood or poor blood circulation. Possible causes include lung issues like asthma or pneumonia, airway problems like choking or croup, and heart conditions such as heart failure or congenital heart disease. Additional factors like Raynaud’s, certain medications, blood clots, exposure to cold air or water, and tight clothing or jewelry can also contribute.
Recognizing cyanosis involves observing a blue or grey hue on the lips, tongue, gums, skin (especially noticeable on palms, soles, lips, gums, and inside eyelids), ears, and under nails. If you or your child experiences sudden discoloration, particularly on brown or black skin, accompanied by difficulty breathing, chest pain, confusion, drowsiness, dizziness, or unusual limpness, seek medical attention promptly.
The specific treatment for cyanosis varies based on its underlying cause. If these symptoms manifest, contact your GP promptly, as they may indicate a serious medical issue.
