What is a common complication of untreated strep throat?

Rheumatic fever is a notable complication of untreated strep throat, which is caused by infection with group A Streptococcus bacteria. When strep throat is left untreated, the body may mount an autoimmune response against its own tissues, particularly affecting the heart, joints, skin, and central nervous system. This autoimmune reaction can lead to inflammation, resulting in serious conditions such as carditis, which can damage heart valves, and arthritis.

The risk factors associated with developing rheumatic fever after untreated strep throat reveal the importance of prompt diagnosis and proper treatment of streptococcal infections. By addressing strep throat quickly with appropriate antibiotics, the incidence of rheumatic fever can be significantly reduced, underscoring the critical nature of recognizing and treating this common pediatric infection effectively.

In contrast, while glomerulonephritis can occur following a streptococcal infection, it more commonly arises after skin infections rather than pharyngitis and is not primarily the result of untreated strep throat. Otitis media, an infection of the middle ear, might occur in children, especially those with respiratory infections or nasal congestion, but it is not a direct complication of untreated strep throat. Anemia does not have a specific connection to untreated st
