A red belly button is often caused by a fungal or bacterial infection in the area, states SpeedyRemedies. The most common fungi that causes redness in the belly button region is Candida albicans that thrives in dark, moist and warm areas, explains MedGuidance.
Infection in the belly button is often the result of poor hygiene habits. Belly button piercing is another common cause of infection and associated redness in the belly button area. The belly button area is dark, deep and damp, making it favorable for the growth of micro-organisms such as bacteria and fungi. In addition, soap, sweat and any other substance deposited in the region, if not cleaned and removed can also contribute to infection and redness in the navel, reports Top 10 Home Remedies.
Sometimes, surgeries that involve the navel can also lead to redness due to infection in the region. Health conditions such as obesity and diabetes, exposure to the ultraviolet rays of the sun and sebaceous cysts can also contribute to redness on and around the belly button, states Top 10 Home Remedies. The risk for belly button infection and redness is higher in people with deep navels. Apply antibiotic cream and clean the area thoroughly to avoid the problem, states SpeedyRemedies.
