The relationship between diabetes and angular cheilitis
Studies show that fungi such as Candida rely on glucose in the body to survive. For this reason, people who have diabetes are more susceptible to fungal infections such as angular cheilitis. People with diabetes [4] have excess glucose in their bodies. Fungus in the body can thrive in an environment with extra glucose. According to studies, people with diabetes have an unstable immune system and may experience several difficulties fighting off invaders.
You are less likely to have angular cheilitis if you pay adequate attention to your blood glucose level. Your health care provider may advise you to exercise regularly, eat a balanced diet and take your insulin medications correctly to prevent the condition. It would also help stop smoking, as it can worsen the situation.
