Unpleasant odors can warn of illness: Changes you should never ignore

Unusual body odors can be more than just a sign of poor hygiene; they may signal underlying health issues. Paying attention to changes in scent that appear without an obvious reason, particularly when accompanied by other symptoms, is crucial for early detection of potential health problems.

This condition occurs when the body does not have enough insulin, so instead of glucose, it begins to use fat as an energy source, producing ketones.

For instance, a sweet or fruity smell on the breath could indicate diabetic ketoacidosis, a dangerous complication of diabetes. This condition occurs when the body lacks sufficient insulin and begins using fat for energy, producing ketones. Dr. Robert Gabbay, chief medical officer at the Joslin Diabetes Center, notes this can create a distinct odor likened to fruit or nail polish remover. The American Diabetes Association warns this is an emergency requiring immediate medical help, especially if accompanied by increased thirst, frequent urination, fatigue, abdominal pain, or unexplained weight loss.

Fungal infections like athlete's foot can also manifest with a strong, unpleasant odor, alongside itching and skin peeling. Dermatologist Dr. Cameron Rokhsar explains that a combination of fungi and bacteria thriving on damaged skin causes the smell. Left untreated, such infections can increase the risk of bacterial complications.

This condition causes a characteristic odor that many compare to fruit or nail polish remover.

Furthermore, persistent bad morning breath, even with regular oral hygiene, might be linked to obstructive sleep apnea. Dr. Raj Dasgupta, a professor at the University of Southern California, suggests this can happen because mouth-breathers during sleep experience dry mouths, fostering bacterial growth that produces odors. Sleep apnea is associated with increased risks of high blood pressure, heart disease, and diabetes, making it important for individuals experiencing loud snoring, daytime fatigue, or unrefreshed sleep alongside bad breath to consult a doctor.

that smell arises due to a combination of fungi and bacteria that multiply on damaged skin.

While unusual odors are not definitive diagnostic tools, persistent or sudden changes, especially when paired with other symptoms like fatigue, pain, or difficulty breathing, should prompt a visit to a healthcare professional to determine the cause.
