what causes your urine to smell sour
Causes of Urine Odor. 1  Bladder Infection (Cystitis) Bladder infection is an infection of the bladder, usually caused by bacteria or, rarely, by Candida. 2  Dehydration Dehydration is the excessive loss of body water. 3  Diabetes (Type 1 and Type 2) Diabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood.
With dehydration, the urine is more concentrated and may have a stronger ammonia scent than normal. Consumption of certain foods, such as asparagus (which can impart a characteristic odor to urine), and taking some medications may be causes for changes in the odor of urine. The presence of bacteria in the urine, such as with a urinary tract infection (UTI), can affect the appearance and smell of urine.
