Most groin itch is one of the symptoms of ringworm, a skin disease caused by fungal infection of the inner femur, perineum, and buttocks. The incidence of ringworm is relatively high because the femoral area is more suitable for fungal growth. In addition, the thin and tender skin in this area makes Trichophyton rubrum and Trichophyton spp. suitable for growth in the femoral area. Impermeable clothing can increase the local temperature and humidity of the skin and interfere with the barrier function of the stratum corneum. After Trichophyton rubrum and Trichophyton spp. have invaded the skin, they go through several developmental stages, including incubation, enlargement during the resistance to infection, and degeneration. What are the dietary contraindications for itchy groin? 1. Avoid eating spicy and stimulating foods; 2. Avoid eating fishy foods; 3. Avoid eating stimulating drinks.
