The concentration and volume of waste products excreted by the kidneys is a common cause of urine odor. Urine that contains a lot of water and is low in waste products, meaning it is not concentrated, has little to no odor, notes Mayo Clinic. During dehydration, it is typical for urine to have a dark yellow or orange color and to smell like ammonia. Individuals with these symptoms should drink more fluids, especially water, and get medical treatment in case of severe dehydration to avoid other symptoms such as confusion and extreme fatigue, notes Healthline.

Urinary tract infections cause a strong urge to urinate, a burning sensation upon urinating and a strong urine smell. A strong urine odor is also a symptom of liver disease together with abdominal pain, yellow skin or eyes and vomiting, states Healthline. Eating asparagus can cause a change in urine odor due to the breakdown of methyl mercaptan, a sulfur compound also found in garlic. Additionally, sweet-smelling urine is common in diabetes due to high blood sugar levels, claims WebMD.
