9 Body Odors You Should Never Ignore

Your body has a natural scent – everyone does. However, certain changes in body odor can signal an underlying health condition. While most strong odors are harmless results of sweat, diet, or hygiene, some shouldn’t be dismissed. Let’s discuss different unusual body odors that may warrant a doctor’s visit.

Body Odors You Should Never Ignore

1. Fruity-Smelling Breath

If your breath smells sweet or fruity despite good oral hygiene, this could be a sign of uncontrolled diabetes. This type of diabetes-related condition is called diabetic ketoacidosis (DKA), a dangerous situation when your body cannot produce enough insulin. Lack of insulin triggers the body to break down fat for energy instead of glucose, resulting in acids called ketones building up. Acetone, the same stuff in nail polish remover, is one type of ketone that lends a fruity scent to the breath. DKA usually accompanies other diabetes symptoms like extreme thirst, fatigue, and frequent urination.

2. Fishy Vaginal Odor

A fishy odor coming from the vagina is often a sign of bacterial vaginosis (BV). BV is caused by an overgrowth of certain bacteria naturally present in a healthy vagina. Symptoms alongside the smell may include thin, grayish-white discharge or discomfort during urination. This condition requires medication prescribed by a doctor.

3. Breath That Smells Like Feces

Beyond indicating dental issues, breath that smells like feces (or vomit) may suggest a more serious underlying condition. Possible causes include a bowel obstruction, a connection between the esophagus and the windpipe (tracheoesophageal fistula), or issues related to stomach emptying in conditions like gastroparesis.

4. Ammonia-Scented Urine

Urine sometimes has a powerful ammonia odor due to dehydration or certain foods and medications. But, if the ammonia smell persists or worsens, it could signal a potential urinary tract infection (UTI) or problems with the kidneys or bladder. UTIs occur when bacteria multiply in the urinary system, typically causing uncomfortable and inconvenient symptoms like pain or burning during urination.

5. Strong Foot Odor

Everybody gets stinky feet, especially after a sweaty workout. However, a constant foul odor on your feet and shoes that refuses to budge with routine washing might indicate a fungal infection like an athlete’s foot. If your feet also appear red, itchy, and flaky, especially between the toes, an over-the-counter antifungal cream could clear up the situation, but stubborn infections may require a doctor’s visit.

6. Maple Syrup Smell in Urine or Sweat

This unusual, sweet odor could be a sign of Maple Syrup Urine Disease (MSUD) – a rare, inherited genetic disorder. Affecting how the body processes specific amino acids, the build-up of these compounds causes the distinctive maple syrup smell, typically noticeable in a baby’s sweat, urine, and earwax soon after birth. MSUD requires lifelong management under a doctor’s guidance.

7. Unusually Strong Body Odor

Suddenly, you notice a very pronounced, overpowering body odor, which might be a symptom of Trimethylaminuria (TMAU). This metabolic condition creates a buildup of trimethylamine, a chemical byproduct responsible for a body odor often described as fishy, rotten eggs or garbage.

8. Rotten-Smelling Pus from Wounds

It’s normal for cuts and minor wounds to emit a little odor in the healing process. However, a very foul, rotten smell might indicate infection. The smell in infected cuts comes from dead or dying tissue and the associated bacteria growth. See your doctor, as infected wounds could require antibiotics and additional care.

9. Vinegar-Like Body Odor

While most commonly caused by sweat combined with natural skin bacteria, an excessively vinegar-like body odor could point to potential problems with the kidneys or liver. If the smell appears persistent, it’s worth mentioning to your doctor during a regular checkup.


  • Are all unusual body odors serious? No. Often, a specific change in odor might be the result of dietary choices, medication side effects, or even natural hormonal fluctuations.
  • How can I tell if my body odor is concerning? Look for changes that are distinct from your normal scent, persist despite hygienic practices, or appear alongside other concerning symptoms like pain, discharge, or discomfort.
  • I’m concerned about my body odor – what should I do? Don’t hesitate to bring it up with your doctor during a routine visit. They can rule out potential causes or identify an underlying issue and discuss available solutions.
