The Causes and Treatment of Cellulitis
Cellulitis is a common bacterial skin infection that can be painful and, if left untreated, can lead to serious complications. This condition affects the deeper layers of the skin and the tissues underneath.
Causes of Cellulitis
The primary cause of cellulitis is bacteria entering the body through a break in the skin. The most common bacteria responsible are Streptococcus and Staphylococcus. These bacteria can be found on the skin’s surface but only cause an infection when they get into deeper tissues.
Breaks in the skin that can allow bacteria to enter include:
- Cuts, scrapes, or puncture wounds
- Surgical incisions
- Insect or animal bites
- Cracks in the skin caused by conditions like athlete’s foot, eczema, or dry skin
- Sores and ulcers
Certain factors can increase a person’s risk of developing cellulitis, such as a weakened immune system (due to conditions like diabetes or HIV/AIDS), long-term swelling of the arms or legs (lymphedema), and a history of previous cellulitis infections.
Treatment for Cellulitis
Early and prompt treatment with antibiotics is crucial to prevent the infection from spreading and becoming more serious. The treatment plan for cellulitis depends on the severity of the infection.
- Oral Antibiotics: For mild cases, a doctor will typically prescribe a course of oral antibiotics, usually for 7 to 14 days. It is very important to complete the entire course of medication, even if symptoms begin to improve, to ensure the infection is fully cleared.
- Hospitalization and Intravenous (IV) Antibiotics: In more severe cases, such as when the infection is rapidly spreading, accompanied by a high fever, or affecting a person with a weakened immune system, hospitalization may be necessary. In the hospital, antibiotics are administered directly into a vein through an IV to treat the infection more quickly and effectively.
- Home Care and Symptom Management: Along with antibiotics, home care can help manage pain and swelling. This includes:
- Elevating the affected body part to reduce swelling.
- Applying a cool, damp cloth to the area for comfort.
- Taking over-the-counter pain relievers like ibuprofen, if advised by a doctor.
Prevention
You can take steps to reduce your risk of getting cellulitis:
- Practice good skin hygiene: Keep your skin clean and moisturized to prevent cracks.
- Promptly treat any wounds: Clean all cuts and scrapes with soap and water and cover them with a bandage to protect against bacteria.
- Manage underlying conditions: Address skin conditions like athlete’s foot and eczema that can lead to breaks in the skin.
