What causes male urine to smell big and bad?

Recent irregular diet or urinary tract infection is the main cause of male urine smell, bad smell. The state of urine can reflect a person's recent metabolism. If men eat irregularly, eat spicy food for a long time, smoke and drink a lot and drink less water, the food entering the body cannot be completely absorbed, excessive alcohol is converted into acid ester substances, which are excreted in the form of urine, and the higher concentration of food residues and acid ester substances will emit a disgusting smell. Urinary tract infection is also a cause of strong, unpleasant urine smell in men. If the urinary system is infected by bacteria, foreign bacteria multiply in the urethra, breaking down urea into primary or secondary metabolites, which are excreted through urine. If the infection is more serious, the number of bacteria attached to the urinary tract will produce more metabolites and will lead to unpleasant urine smell.
