Why does body odour change during menopause?
During menopause, and even perimenopause, your hormone levels fluctuate, and you may notice you sweat more, have hot flushes or are more prone to stress and anxiety (which can also cause you to sweat more). Your sense of smell may be altered, making you think you smell bad when in reality, you don’t. These factors can all contribute to the change in body odour that many women notice during this time. A drop in oestrogen, along with excessive sweating, can also leave your body and skin feeling dehydrated.
Understanding your sweat glands (eccrine vs. apocrine)
You have two types of sweat glands: eccrine and apocrine. Eccrine glands are found in the areas that produce sweat that is mostly water, i.e. your hands, feet, torso and face. This sweat helps you to cool down and doesn’t really smell.
Apocrine glands, found in your armpits and groin, produce a different kind of sweat that contains fats, proteins, sugar and ammonia, which has a strong scent. When bacteria on your skin break down this sweat, it creates an unpleasant body odour. As excessive sweating is one of the main symptoms of menopause, you may notice you smell bad or different, more often than before.
