5 Body odours that could mean you have a disease

Our bodies naturally have their own distinct odors, but certain changes in body odor can serve as warning signs of underlying health conditions. While body odor alone does not always indicate a disease, it can be a valuable clue that prompts further investigation. In this article, we will explore five specific body odors that could potentially signify an underlying disease, emphasizing the importance of recognizing and addressing these changes.

1. Sweet or Fruity Odor

A sweet or fruity odor on the breath or skin can be an indication of uncontrolled diabetes. When blood sugar levels are high, the body may produce a fruity odor due to the presence of ketones—a byproduct of fat metabolism. If you notice this distinctive smell, it is essential to seek medical attention promptly to evaluate your blood sugar levels and determine appropriate management.

2. Ammonia-Like Odor

An ammonia-like odor emanating from the breath or sweat may suggest kidney or liver problems. The kidneys are responsible for filtering waste products from the blood, while the liver aids in detoxification. If these organs are compromised, waste products like urea can accumulate in the body, resulting in an ammonia-like odor. If you consistently notice this odor, it is crucial to consult a healthcare professional for a thorough evaluation.

3. Rotten or Fishy Odor

A persistent rotten or fishy odor, particularly in the vaginal area, may be an indication of bacterial vaginosis (BV) or a sexually transmitted infection (STI) such as trichomoniasis. BV occurs when there is an overgrowth of certain bacteria in the vagina, leading to an unpleasant odor. Similarly, some STIs can cause changes in vaginal odor. If you experience an unusual odor accompanied by discharge, itching, or discomfort, it is important to consult a healthcare provider for proper diagnosis and treatment.

4. Maple Syrup Odor

A distinctive odor resembling maple syrup can be associated with a rare metabolic disorder called maple syrup urine disease (MSUD). This inherited condition affects the body’s ability to break down certain amino acids. As a result, substances that give off a sweet, maple syrup-like scent accumulate in the urine and sweat. If you or a loved one experience this unique odor, it is crucial to seek medical attention immediately, as MSUD requires prompt diagnosis and management.

5. Foul Breath

Persistent foul breath that does not improve with proper oral hygiene practices may be an indication of underlying oral health issues or digestive problems. Conditions such as gum disease, tooth decay, or infections in the mouth can contribute to bad breath. Additionally, digestive disorders like gastroesophageal reflux disease (GERD) or gastrointestinal infections can also lead to foul-smelling breath. If you consistently experience bad breath despite adequate oral care, it is advisable to consult a dentist or healthcare professional for a comprehensive evaluation.


Our body odors can provide valuable insights into our overall health. While not all changes in body odor are cause for alarm, recognizing certain distinct odors can serve as early warning signs of underlying diseases. Sweet or fruity odors, ammonia-like odors, rotten or fishy odors, maple syrup odors, and persistent foul breath may indicate the presence of diabetes, kidney or liver problems, BV or STIs, MSUD, or oral and digestive disorders, respectively. It is crucial to consult with healthcare professionals for proper evaluation and diagnosis if you notice any concerning changes in body odor. Early detection and intervention can lead to timely treatment and improved health outcomes.
