How to Get Rid of an Ammonia Smell from Your Body

An ammonia smell on your skin, breath or sweat can be unsettling. It often indicates that your body is breaking down protein or that certain substances are sitting on your skin and reacting with bacteria. In most cases, simple lifestyle adjustments will eliminate the odor. In some situations, however, an ammonia-like scent may signal an underlying health issue that needs medical attention.

Below, you’ll find:

• Common causes of an ammonia smell
• At-home strategies to neutralize the odor
• When to seek professional help

Why You Might Smell Like Ammonia

Your body produces ammonia as part of normal metabolism. When protein breaks down, it forms amino acids. The liver converts excess nitrogen from these amino acids into urea, which is eliminated in urine. If urea or ammonia bypasses this process or builds up on your skin, you can notice that distinctive “nail-polish‐like” or bleach-like scent.

Possible triggers include:

• High-protein diets or low-carb/keto eating
• Intense exercise or muscle breakdown
• Dehydration
• Skin surface bacteria reacting with sweat
• Kidney or liver dysfunction
• Metabolic or genetic conditions (rare)

At-Home Tips to Eliminate the Smell

Most ammonia odors will clear up once you address the underlying trigger. Try these steps:

1. Improve Personal Hygiene

• Shower daily with a mild antibacterial soap.
• Focus on sweat-prone areas: underarms, groin, feet, back.
• Dry thoroughly before dressing to limit bacterial growth.

2. Adjust Your Diet

• Balance protein intake: aim for 0.8–1.2 grams of protein per kg of body weight daily (about 55–80 grams for a typical adult).
• Incorporate more complex carbs (whole grains, fruits, vegetables) to help your body burn glucose instead of protein.
• Reduce or space out very high-protein meals (e.g., shakes, bars).

3. Stay Hydrated

• Aim for 8–10 cups (1.9–2.4 liters) of water a day, more if you’re active or live in a hot climate.
• Proper hydration helps flush urea and ammonia from your system, reducing buildup on the skin.

4. Wear Breathable Clothing

• Choose natural fibers (cotton, bamboo) that let your skin breathe.
• Change sweaty workout clothes promptly, and wash workout gear after each use.

5. Use pH-Balancing Skin Products

• A mild, slightly acidic body wash (pH around 5.5) can help restore your skin’s barrier and deter odor-causing bacteria.
• Consider sprays or wipes with zinc or tea tree oil for on-the-go freshness.

6. Manage Exercise Intensity

• If you train intensely, take rest days to allow muscle repair.
• Post‐workout, shower promptly and change into fresh, dry clothes.

7. Try Natural Deodorizers

• Applying a paste of baking soda and water can neutralize surface odor—use as a quick underarm scrub, rinse well.
• Apple cider vinegar diluted 1:1 with water can rebalance skin pH; apply with a cotton ball, then rinse.

8. Support Gut Health

• A healthy microbiome can reduce skin and body odors.
• Include probiotic-rich foods (yogurt, kefir, fermented vegetables) or discuss a probiotic supplement with your doctor.

When to Consider Underlying Health Issues

If the ammonia smell persists despite good hygiene and dietary changes, consider possible medical causes:

• Kidney dysfunction: Kidneys filter urea; if they’re not working well, nitrogenous waste may back up.
• Liver issues: The liver converts ammonia to urea; impaired function can allow ammonia to accumulate.
• Metabolic disorders: Rare genetic conditions (e.g., urea cycle disorders) can lead to ammonia buildup.
• Uncontrolled diabetes: Ketone production can cause a chemical odor on the breath and skin.
• Muscle damage: Conditions like rhabdomyolysis release nitrogenous waste into the bloodstream.

Signs you should seek medical advice:

• Persistent ammonia smell despite lifestyle changes
• Other symptoms such as fatigue, confusion, nausea, swelling of legs or abdomen
• Noticeable changes in urination (frequency, color, odor)
• Jaundice (yellowing of skin/eyes) or abdominal pain

If you’re uncertain what’s causing your symptoms, you might consider a free, online symptom check, using the doctor approved Ubie Symptom Checker.

Medical Evaluation and Treatment

When you see a healthcare provider, they may recommend:

• Blood tests (kidney panel, liver enzymes, electrolytes)
• Urinalysis (to check urea levels and look for infection)
• Imaging (ultrasound, CT scan) if organ dysfunction is suspected
• Referral to a specialist (nephrologist, hepatologist, endocrinologist)

Treatment will depend on the cause:

• Improving kidney or liver function through medication or lifestyle changes
• Dietary modifications for metabolic disorders
• Managing diabetes or other chronic conditions
• Addressing rare genetic issues with specialized therapies

Key Takeaways

• An ammonia odor usually results from protein breakdown, dehydration or surface bacteria.
• Simple steps—balanced diet, hydration, hygiene, breathable clothing—often clear the smell.
• Persistent odor may signal kidney, liver or metabolic issues that require medical attention.
• Use pH-balancing washes, natural deodorizers and probiotics to support your body’s balance.
• For peace of mind, try a free, online symptom check, using the doctor approved Ubie Symptom Checker.
• Always speak to a doctor about any symptom that could be life-threatening or serious.

By taking these steps, you can address the ammonia smell at its source and feel confident in your body again. If concerns remain, your healthcare provider can guide you toward the right tests and treatments.
