Experiencing smelly urine can be an embarrassing and common situation. Foods like asparagus and Brussels sprouts are well-known culprits, causing many to worry about using public restrooms after consuming these items. However, having odorous urine is a normal occurrence and is often influenced by dietary choices.
Common Dietary Culprits
“Urine consists of water and waste products your body doesn’t need, which is why they’re expelled,” explains Olivia Baker, a registered dietitian and nutritionist at Mayo Clinic in Arizona. Certain ingredients in medications, like amoxicillin, or supplements, like vitamin B, can also affect urine odor. Dehydration can play a role as well, leading to more concentrated urine that smells like ammonia.

Dr. Stephen Savage, a professor and interim chair of urology at the Medical University of South Carolina, points out that many foods have breakdown products excreted in urine, resulting in characteristic odors. Asparagus, for instance, contains an acid that, when broken down, results in chemical compounds like methanethiol and S-methyl thioester, producing a strong odor. Broccoli, metabolized similarly, also excretes sulfur-related compounds, contributing to a similar smell.
Other foods and beverages known to affect urine odor include coffee, black tea, cabbage, dried fruit, curry, alcohol, eggs, Brussels sprouts, garlic, cumin, onions, and fish. These items contain chemical compounds that influence the overall smell of urine.
Medical Conditions Linked to Urine Odor
While diet is a primary factor, smelly urine can sometimes indicate an underlying medical condition. Urinary tract infections (UTIs) are a common cause, usually accompanied by other symptoms like pain or discomfort. Dr. Savage mentions that unusual metabolic disorders can also cause abnormal urine smells.
Medical conditions such as chlamydia, bladder fistula, liver failure, trichomoniasis, gonorrhea, and poorly controlled diabetes can significantly alter urine odor. Olivia Baker adds that if you haven’t consumed any known food, supplement, or medication affecting urine odor and notice a sweet or foul smell for more than a couple of days, it may be a sign of a medical condition that needs further evaluation.
When to Seek Medical Attention
Most instances of smelly urine are harmless and linked to dietary choices. However, persistent or unusual odors, especially those not related to food or supplements, should not be ignored. Dehydration can be managed by increasing fluid intake, but if the smell persists, it could indicate a more serious issue. If you experience other symptoms like pain, discomfort, or changes in urine color, it’s essential to seek medical attention. Early diagnosis and treatment can help address any potential health issues and prevent complications.

While smelly urine is often related to diet, it can sometimes signal a medical condition that requires attention. Understanding the common causes and knowing when to seek medical help can ensure better health and peace of mind.
