Causes of Abscesses
Most abscess cases (English: Abscess) arise from infection by Staphylococcus bacteria. When these bacteria enter the body, the immune system responds by attacking them, leading to inflammation at the infection site and tissue death. This process results in the formation of a cavity filled with pus, which is a combination of white blood cells, bacteria, and dead tissue. If appropriate treatment is not sought, the abscess can enlarge, causing increased pain. It is important to note that abscesses can also occur due to viral, fungal, or parasitic infections in rare instances.
Skin Abscess
This type of abscess develops when bacteria infiltrate from the skin’s surface to its inner layers. The risk of contracting a skin abscess is heightened if one of the skin glands, such as sweat or sebaceous glands, becomes blocked, or if there is an injury or cut on the skin. Skin abscesses are more frequently observed on the hands, feet, buttocks, genital region, and under the arms.
Internal Abscesses
Internal abscesses form when an infection spreads from a superficial area into the body. In some cases, the infection may travel via the bloodstream. Factors that elevate the risk of developing internal abscesses include:
- Ruptured intestines.
- Surgical procedures in the abdominal area.
- Exposure to certain types of injuries and infections.
- Severe head injuries.
- Chemotherapy for cancer.
- Human Immunodeficiency Virus (HIV) infection.
Dental Abscess
A dental abscess occurs when bacteria reach the pulp of a tooth, which contains connective tissues, blood vessels, and nerves associated with the tooth. This infection results in swelling and inflammation of the tooth root. Factors contributing to a dental abscess include fractures or cracks in the tooth, tooth decay, or cavities.
