A host of things can change things when it comes to using the toilet as lots of foods and drink have the ability to change the way your urine smells.
Most of the time, the change in odour is down to a change in diet or eating something in particular and is nothing to worry about. For example, after having asparagus with your dinner the night before - or even eating a lot of garlic can make things a little smellier than usual - you could notice the "strong-smelling chemicals" that can enter your pee, according to the NHS.
Drinks like coffee can also have a similar impact. However, there are some occasions where a change to the smell of your pee could indicate certain health issues and conditions, which may need medical attention.
