Which condition predisposes to fungal intertrigo in intertriginous skin folds?

• A. Obesity and diabetes mellitus
• B. Hypertension predisposes to fungal infections
• C. Vitamin C deficiency predisposes to fungal infections
• D. Chronic liver disease predisposes to fungal infections

Answer: (A)

Intertrigo in skin folds thrives in a warm, moist environment where fungal organisms such as Candida and dermatophytes grow. Obesity increases the number and size of skin folds and the amount of sweating, creating persistent moisture and maceration that break down the skin barrier and foster fungal growth. Diabetes mellitus adds a further risk because high blood glucose fuels fungal proliferation and impairs immune defenses, making infections more likely and harder to control in these moist folds. Hypertension, vitamin C deficiency, and chronic liver disease do not create the same direct combination of excessive moisture, friction, and immune compromise in intertriginous areas, so they are not as strong predispositions for fungal intertrigo.
