Why human urine can smell like ammonia
Urine is mostly water with salts and waste such as urea and uric acid. Occasionally, when concentrated (by drinking little water) it can release a ammoniacal odor more pronounced, which usually disappears as soon as you rehydrate. Other factors such as diet, certain medications or supplements, or even the café (which is a diuretic), may temporarily intensify the odor.
When the smell persists for more than 48 hours, we speak of a sign that should be observe, especially if accompanied by other urinary or general symptoms. In these cases, the cause may go beyond simple dehydration and require medical evaluation.

- Intimate hygiene products (douching): frequent use alters the microbiota and may increase unwanted odors. Daily use is not recommended.
Medical conditions to consider
Although in most cases the intense odor is benign and transient, sometimes it reveals a underlying problemThese are some medical causes that can cause bad-smelling urine and require monitoring:
- Diabetes: When there is excess glucose in the blood, some of it is eliminated in the urine, which may acquire an odor sweetish. In addition, it irritates the bladder and increases urinary frequency.
- Urinary tract infection (UTI): bacteria in the urethra or bladder metabolize urea, appear nitrites and leukocytes, and urine may become cloudy and foul-smelling; it is often accompanied by burning, urgency, and mild fever.
- Bacterial vaginosis: runs with fishy smell, abnormal flow and discomfort when urinating.
- Kidney stones: when they get stuck in the urinary tract they cause intense pain; if they become complicated, they can produce infections and bad smell.
- Kidney or liver failure: alter the elimination of waste and bilirubin, changing the color and smell of urine.
- STDs: irritate and inflame the urethra, with discharge and unpleasant smell.
- Bladder fistula: abnormal communication between the intestine and bladder (due to surgery or disease), which allows the entry of bacteria and marked bad smell.
- Phenylketonuria (rare, genetic): The body does not break down certain amino acids, giving the urine a particular smell.
- Pregnancy: hormonal changes (estrogen, progesterone) can modify the odor temporarily.

A simple urine analysis detects infection and guides treatment (e.g., antibiotics for UTIs). In specific cases, they may order tests such as a cystoscopy to study the urinary tract.
