What Is The Main Cause Of Cellulitis?
Cellulitis is caused by a group of bacteria that are normally present on the skin, such as Streptococcus and Staphylococcus. The infection can occur when these bacteria enter the skin through a break or cut. Below are some common causes of cellulitis: (3)
- Injury to the skin: Any injury to the skin, such as a cut, scrape, or puncture wound, can provide an entry point for bacteria that can cause cellulitis.
- Weak immune system: Immunocompromised people (those with a weakened immune system) due to diseases such as HIV, diabetes, or cancer are at higher risk for cellulitis.
- Obesity: Obesity can lead to skin folds, which can create a warm, moist environment that is favorable for bacterial growth and infection.
- Insect bites: Insect bites, particularly from spiders or ticks, can cause cellulitis.
- Intravenous (IV) drug use: Sharing needles and injecting drugs can lead to cellulitis.
- Surgical wounds: Surgical wounds can become infected with bacteria that cause cellulitis.
- Lymphatic obstruction: Obstruction of the lymphatic system, which helps to clear bacteria and other debris from the body, can cause cellulitis.
- Poor circulation: Poor circulation can lead to reduced blood flow and oxygenation to the skin, making it more susceptible to bacterial infections.
- Athlete’s foot: Fungal infections like athlete’s foot can cause cracks in the skin that may allow bacteria to enter and cause cellulitis.
