What does it mean urine smell like rotten eggs?

Urine that smells like rotten eggs often indicates the presence of sulfur compounds, which can result from certain foods, medications, or medical conditions. Common causes include a diet high in sulfur-rich foods (like garlic or asparagus), dehydration, or urinary tract infections (UTIs) caused by specific bacteria. If the smell persists or is accompanied by other symptoms, it's advisable to consult a healthcare professional for further evaluation.
