These infections occur when harmful microorganisms such as bacteria, viruses, or parasites invade the digestive system, leading to inflammation and discomfort. While most stomach infections are mild and resolve on their own, some can lead to serious complications if left untreated. Understanding the symptoms, causes, and treatment options is essential for effective management and recovery.
