A person’s breath may smell like urine or ammonia due to numerous causes, including nasal congestion, stomach infection, diet, and more. A foul taste in the mouth may indicate bad breath.
Read on to learn more about the possible reasons for breath that smells like urine and the treatment options.
Nasal congestion, or a stuffy nose, refers to a runny nose or mucus buildup in the nasal cavities.
Both nasal congestion and sinusitis can result from bacterial infections, allergies, or irritation of the nasal cavities.
They often result in bad breath, which in some people could smell similar to urine.
People can treat nasal congestion and sinusitis with one or more of the following, depending on the cause:
- anti-inflammatory medication
- allergy medicines
- nasal corticosteroid sprays
- surgery (in chronic cases, to remove blockages)
Some home remedies that may provide quick relief include:
- inhaling steamy moist air
nasal irrigation techniques
- increasing fluid intake to thin out mucus
- applying warm towels or bottles to the affected areas to reduce the pressure buildup
A common bacterium called Helicobacter pylori (H. pylori) is present in nearly one-half of the world’s population. Most people, however, do not show any symptoms.
Additional symptoms of H. pylori complications can include persistent pain or intermittent discomfort in the stomach, lack of appetite, nausea or vomiting, bloating, weight loss, and dark-colored stools.
People should talk to a doctor if they suspect an H. pylori infection. If the doctor diagnoses an infection, treatment may include:
The foods that people eat can affect their breath, on both a temporary and long-term basis.
Certain foods react in the body to produce ammonia and its byproducts, which have odors resembling that of urine.
This is common in people who consume a high-protein or ketogenic diet. A high intake of specific foods such as onions and garlic can also lead to bad breath.
Excessive alcohol consumption can also affect breath by lowering
In most cases, it is easy to treat bad breath when it results from dietary causes.
People should check for particular foods in their diet that could be causing the problem and reduce their intake accordingly.
A well-balanced diet with multiple daily servings of fruit and vegetables will also result in a healthy digestive system and potentially better-smelling breath.
CKD comprises a range of diseases and disorders that damage the kidneys and limit their ability to filter body waste. This leads to a serious buildup of toxins in the body, including ammonia, which causes urine-scented breath.
Other health complications that can result from CKD include anemia, high blood pressure, abnormal electrolyte levels, fluid buildup, heart disease, increased risk of stroke and heart attack, and kidney failure.
It is not possible to cure CKD, so treatment aims to relieve symptoms and help patients manage the condition.
To manage CKD, people will need to make lifestyle changes and possibly also take medications for high blood pressure and high cholesterol.
People with advanced stage CKD may need dialysis or a kidney transplant.
Uremia is the end stage of kidney failure. As the kidneys will no longer be able to filter waste effectively, waste substances such as urea, creatine, and other nitrogenous products build up in the blood rather than leaving the body in the urine.
The accumulation of these nitrogenous compounds in the system often results in breath smelling like ammonia.
Uremia is a severe medical condition that requires urgent care and often hospitalization. Doctors will determine the underlying cause of uremia and recommend dialysis to filter the blood.
Some people may also require a kidney transplant if the kidneys are too damaged to filter blood on their own.
A foul taste in the mouth is the primary indication of bad breath.
Some other quick ways to check your breath include:
- Licking your wrist and allowing it to dry for a moment before smelling it.
- Flossing between two teeth toward the back of your mouth and smelling the floss.
- Using a tongue scraper to scrape the tongue gently, then smelling the scraper.
People can help to avoid bad breath by adopting the following practices:
- Maintaining good oral hygiene and checking with a dentist if they observe a persistent problem with their breath odor.
- Drinking plenty of fluids, including water, juices, tea, and other non- alcoholic beverages.
- Reducing intake of foods and beverages such as coffee, soft drinks, dairy, red meat, and refined and processed foods.
- Balancing the diet with foods that include fruit, vegetables, and legumes.
- Avoiding excessive amounts of alcohol, as it decreases saliva production.
- Quitting smoking to minimize damage to the mouth and gums and to improve oral health.
There are many conditions that can cause breath to smell like urine or ammonia. Some of these are temporary and resolve on their own, while others may require medical attention.
A dentist will be able to treat many of the causes of bad breath, but people should also maintain good oral hygiene and health.
