LIPS

WHAT TO LOOK FOR It’s not unusual to suffer from chapped lips in the winter, but painful cracks or splits at the corners of your mouth can be a sign that you are deficient in nutrients, including vitamin B, iron and zinc, says GP Dr Radha Modgil. WHAT TO DO “Try to follow a healthy, balanced diet with lots of fresh, unprocessed food,” she advises. “If there’s no improvement, talk to your GP about being tested for coeliac disease, which can be managed with a B12 supplement and gluten-free diet.”
