situs inversus is a rare medical condition where a person's internal organs are mirrored from their normal positions. For example, the heart may be located on the right side of the chest instead of the left. This condition occurs during fetal development and affects about 1 in 10,000 people. Most individuals with situs inversus lead normal, healthy lives without any symptoms. However, some may face complications if they also have situs inversus totalis, where all organs are reversed, or situs inversus with dextrocardia, where the heart is on the right side. Regular medical check-ups can help monitor any potential issues.
