Constant lip licking can be a sign of infection - candida, also known as oral thrush, is by far the most common. This yeast infection often takes hold at the edges of the mouth, causing cracks in the corners, which feel dry and itchy and make you want to lick your lips more often.

What can you do? It's the same bug that causes vaginal thrush and is treated with similar anti-fungal medication - usually by tablet or mouthwash. To stop it returning, experts suggest eating live yoghurt daily, as its active bacteria can help restore your mouth's natural balance.
