Body odour is a natural part of life, but certain smells can go beyond the usual sweat or musk. Though many are harmless, some unusual or intense odours could signal underlying health issues.
While it might be tempting to cover them up with deodorants or perfumes, there are certain scents that deserve closer attention. Here are ten body odours that men should never ignore, as they may signal a deeper health problem.
If your breath smells unusually sweet, like fruit or acetone, it could be a sign of diabetes. This condition is known as diabetic ketoacidosis (DKA), which occurs when blood sugar levels become dangerously high, and the body starts breaking down fat for energy. Left untreated, DKA can lead to life-threatening complications, so if you notice this scent, consult a doctor immediately.
A persistent fishy odour, especially from sweat, could indicate trimethylaminuria, a metabolic disorder where the body is unable to break down a compound called trimethylamine. This condition can cause sweat, breath, and urine to smell strongly of fish. While rare, it’s a condition that requires medical attention to manage effectively.
Chronic bad breath, also known as halitosis, can be a sign of more than just poor oral hygiene. It could indicate underlying issues like gum disease, chronic sinus infections, or even digestive problems like gastroesophageal reflux disease (GERD). If brushing and flossing don’t help, it’s time to see a dentist or doctor.
If your sweat smells like ammonia after exercising, it could be a sign that your body is burning protein for fuel instead of carbohydrates. This is common in people on low-carb diets or those who aren’t eating enough before strenuous activity. However, it may also indicate kidney issues, as ammonia is a byproduct of protein metabolism that should be filtered out by the kidneys.
Occasional flatulence is normal, but if you notice a foul or unusual smell, it could be a sign of a gastrointestinal issue. Conditions like lactose intolerance, celiac disease, or an imbalance in gut bacteria can cause excessive or particularly smelly gas. If dietary changes don’t help, it’s worth consulting a gastroenterologist.
A musty smell, especially from the armpits, could be a sign of phenylketonuria (PKU), a genetic disorder that affects the body’s ability to process phenylalanine, an amino acid found in many foods. Untreated, PKU can lead to developmental issues and cognitive impairments, so early detection is key.
Urine typically has a mild scent, but if you notice a strong or unusual odour, it could indicate dehydration, a urinary tract infection (UTI), or even kidney stones. A sweet-smelling or musty urine odour could also be a sign of diabetes or liver problems. If the smell persists despite drinking enough water, see a doctor for further evaluation.
A sour smell from your body, particularly after sweating, might suggest a diet high in sugar and processed foods. These foods can alter your body’s pH balance, making your sweat more acidic.
Additionally, stress-induced sweat, which comes from apocrine glands, contains proteins and lipids that bacteria break down, producing a sour scent. Addressing diet and stress levels can help, but if the odour persists, it’s worth getting checked.
While smelly feet are common, a persistent, overpowering odour could indicate an athlete's foot or another fungal infection. Fungus thrives in warm, moist environments like shoes, leading to a foul smell. If your feet stay smelly despite good hygiene, consider using antifungal treatments or consult a podiatrist.
If your breath or sweat smells metallic, it could be a sign of kidney disease. The kidneys are responsible for filtering waste from the blood, and when they’re not functioning properly, a buildup of toxins can occur. This can lead to a metallic odour in your breath or sweat, along with other symptoms like fatigue, swelling, or changes in urination.
It’s important to listen to what your body is telling you. If you notice any unusual or persistent odours, don’t hesitate to consult a healthcare professional. Catching these issues early can make a big difference in your overall health and well-being.
