Body odour has long been associated with poor hygiene. It’s an assumption many of us make without a second thought. But medical experts say the reality is far more complex. For some individuals, persistent body odour isn’t a result of skipping a shower or forgetting deodorant but it’s caused by an underlying medical condition that deserves understanding rather than judgement.
One of the most commonly misunderstood conditions is hyperhidrosis, a disorder that causes excessive sweating far beyond what the body requires to regulate its temperature. It affects millions of people worldwide, yet many continue to suffer in silence because of the stigma attached to sweating and body odour.
The human body contains millions of eccrine sweat glands, responsible for producing sweat to cool the body. In people with hyperhidrosis, these glands become overactive due to excessive nerve stimulation. The result is continuous sweating even in cool weather or while sitting still.
Contrary to popular belief, sweat itself has no smell. Body odour develops when naturally occurring bacteria on the skin break down sweat, producing compounds that create an unpleasant smell. This means someone with hyperhidrosis may experience persistent body odour despite showering regularly, using deodorants, and maintaining excellent personal hygiene.
“Persistent body odour isn’t always a hygiene issue. Hormonal imbalances, excessive sweating and certain medical conditions can all contribute. If body odour persists despite good hygiene, it’s important to seek medical evaluation rather than ignore it or assume it’s simply a lifestyle issue.” Says Dr. Shashank Shetty, Endocrinologist at Lilavati Hospital, Mumbai
Hormones also play a significant role in regulating how much we sweat. An overactive thyroid can increase the body’s metabolism, making people sweat more than usual. Hormonal fluctuations during puberty, pregnancy and menopause can also temporarily alter body odour. In some cases, uncontrolled diabetes and other endocrine disorders may affect how the body smells, making medical evaluation essential when symptoms persist.
Lifestyle factors can further influence body odour. Certain foods, alcohol, smoking, stress, dehydration and some medications may alter body chemistry. However, these are often contributing factors are not necessarily the root cause. The key is identifying whether the body odour is temporary or a sign of an underlying health condition.
The emotional impact of hyperhidrosis is often underestimated. Many people avoid social gatherings, hesitate to shake hands, feel uncomfortable in professional settings or constantly worry about what others think of them. For them, the fear of being judged can be more debilitating than the condition itself.
“The body communicates through symptoms. While nutrition, hydration, sleep and stress management influence overall wellbeing, persistent body odour should never be ignored or shamed. Compassion and timely medical guidance are far more valuable than assumptions.” Says – Luke Coutinho, Integrative Lifestyle Expert
The good news is that hyperhidrosis and many conditions associated with excessive sweating are treatable. Depending on the diagnosis, doctors may recommend prescription-strength antiperspirants, oral medication, iontophoresis, Botox injections or treatment for an underlying hormonal disorder. Lifestyle modifications can complement medical treatment, but they should never replace a proper diagnosis.
What often needs treatment isn’t just the condition, it’s the stigma surrounding it. Too often, people living with excessive sweating are labelled as unhygienic, careless or irresponsible, when in reality they may be managing a chronic medical disorder every single day.
The next time you notice someone struggling with excessive sweating or body odour, pause before making assumptions. Sometimes, what appears to be a hygiene issue is actually a medical condition hiding in plain sight.
Awareness begins with empathy. And in this case, understanding the science behind body odour may be the first step towards replacing judgement with compassion.
