Gauged earrings, also known as ear gauges or plugs, can cause infections if they are not properly cared for or if the jewelry used is of low quality. Infection can occur when bacteria or other microorganisms enter the piercing site, causing redness, swelling, pain, and discharge.

To reduce the risk of infection, it's important to keep the gauged ear piercing site clean and dry. Proper aftercare, such as cleaning the area with saline solution or mild soap and water, and avoiding touching the piercing site with dirty hands, can help prevent infections. It's also important to use high-quality jewelry made from materials such as surgical steel, titanium, or niobium, and to avoid wearing earrings that are too tight or small for the piercing.

If you experience signs of infection, such as fever, increased pain, or pus drainage, it's important to seek medical attention from a healthcare professional. They may prescribe antibiotics or other treatments to help clear the infection.
