The Most Common Reasons Why Urine Might Have a Strong Odor

Have you ever noticed that your urine smells like sulfur? In most cases, the cause is benign and the odor quickly disappears naturally. However, in some cases, the odor may be due to an illness that requires medical or even surgical treatment. Below is a list of the most common reasons why urine might have a strong odor.



The food you eat

Certain foods, such as asparagus, fish, onions, and garlic, can give urine a sulfurous odor. But this does not last long. Once digestion is complete, the odor returns to normal. However, if you cannot stand the smell, you can stop eating these types of foods.

Some drugs, such as vitamin B supplements or sulfonamides used to treat diabetes and rheumatoid arthritis, can also cause a sulfurous smell in the urine. To reduce this, you can try drinking more water. But if the problem persists or gets worse, you may need to ask your doctor to change your treatment.


Dehydration can also cause sulfurous odors. Urine is a mixture of water from food, chemicals, and toxins that our bodies filter out before releasing them. If you don’t drink enough water, your urine will be more concentrated, darker, and will smell stronger. If you have trace amounts of sulfur in your body, dehydration can contribute to this odor in your urine. To take care of this problem just drink more water!

Urinary tract infection

One of the first signs of a urinary tract infection is a strong ammonia smell. The bacteria responsible for the infection is the cause of this unusual odor. It can also cause a cloudy or bloody appearance. If you have a urinary tract infection, see a doctor as soon as possible, before it gets worse, for proper treatment.

Liver Issues

If your liver is no longer working efficiently, your body may have a harder time filtering toxins from your urine, which can cause your urine to smell bad If you have liver problems, other symptoms such as darker-than-normal urine, nausea, vomiting, swollen legs, and feet, yellowing skin or abdominal pain should also draw your attention. If you are concerned, see your doctor immediately.

Treatment varies depending on the cause, but your specialist will likely recommend dietary changes to help you adopt a healthier lifestyle.

The Prostate

When the prostate becomes infected, it becomes inflamed and causes prostatitis. One of the symptoms of this condition is a bad odor in the urine. If you suffer from this condition, you may also have a constant urge to urinate and difficulty doing so, abdominal pain and pain between the rectum and scrotum. Treatment for prostatitis varies depending on the cause. Your doctor may prescribe alpha-blockers to relax the muscles in this area or give you anti-inflammatory treatment to reduce pain and swelling.


Due to the formation of ketones that are produced when blood sugar levels are high, people with diabetes may also cause a strong smell in their urine. They may also experience symptoms such as frequent urination, intense thirst, intense hunger, severe fatigue, and blurred vision. Other known symptoms include unexplained weight loss, recurrent vaginal and skin infections, and difficulty healing wounds. As for the smell of sulfur in the urine, diabetics should check that they are using their insulin correctly. Better control of blood sugar levels can eliminate this symptom.

Cystinuria is characterized by abnormal transport of amino acids in the renal tubules. The disease causes cystine stones and can also cause the urine to have a sulfurous smell. Cystinuria is usually treatable. In addition to appropriate medical treatment, your doctor may advise you to avoid foods rich in methionine, a precursor to cysteine. You may also be advised to limit your intake of meat, fish, eggs, and cheese. Sometimes, however, medication and dietary changes are not enough and surgery is necessary to treat the condition.


You can develop hypermethioninaemia if you eat too many foods that contain methionine (nuts, pork, smoked brisket, tuna, etc.) or if your body does not break down the amino acids properly. Then you may have difficulty standing or walking. Also, your urine, breath, and sweat may smell like sulfur. You need to see a doctor immediately, who should advise you about changes in your diet and lifestyle.

Gastrointestinal fistula

A gastrointestinal fistula is an abnormal opening in the digestive system that causes leakage of stomach fluids into the stomach or intestines. If you have a gastrointestinal fistula, you may have frequent urinary tract infections and your urine will have a sulfurous smell. These fistulas most often occur after intra-abdominal surgery. They can also occur in people with chronic digestive problems. The solution for removing them depends on their size and the amount of gastric fluid leaking from them. Some fistulas heal on their own, while others require surgery and regular monitoring to prevent serious conditions such as sepsis.
