Are You at Risk for Cellulitis? Key Factors to Watch
Published: Sep 25, 2024
Cellulitis can affect anyone, but certain factors significantly increase your chances of developing this skin infection. Knowing your risk can help you take proactive steps to protect your skin health.
Skin Conditions and Injuries
Any break in the skin can be an entry point for bacteria that cause cellulitis. This includes cuts, scrapes, burns, insect bites, and surgical wounds. Chronic skin conditions like eczema, psoriasis, or athlete's foot also increase risk by creating potential entry points. Even seemingly minor issues like dry, cracked skin or ingrown toenails can make you more susceptible.
Circulatory and Lymphatic Issues
Poor circulation, often due to conditions like diabetes or peripheral artery disease, can increase your risk of cellulitis. These conditions can slow wound healing and reduce your body's ability to fight off infection. Lymphedema, a condition that causes swelling due to a build-up of lymph fluid, also significantly increases cellulitis risk, particularly in the affected limb.
Weakened Immune System
A compromised immune system makes it harder for your body to fend off infections, including cellulitis. This can be due to conditions like HIV/AIDS, leukemia, or liver disease. Certain medications, such as chemotherapy drugs or long-term steroid use, can also weaken your immune response and increase your risk.
Previous History and Lifestyle Factors
If you've had cellulitis before, you're at higher risk of developing it again. Obesity is another significant risk factor, as excess weight can affect circulation and create skin folds where bacteria can thrive. Intravenous drug use increases risk due to potential skin damage and introduction of bacteria. Certain occupations or hobbies that increase your risk of skin injuries can also make you more susceptible to cellulitis.
