        Frequently Asked Questions<\/h3>\n

        Can body odor changes always mean something serious?<\/strong>
        \nNo. Diet, medications, hormones, and infections are far more common causes. Persistent, unexplained changes simply deserve a conversation with your doctor.<\/p>\n

        How accurate are animals or machines at detecting health-related odors?<\/strong>
        \nResearch shows trained dogs and electronic nose devices can identify certain VOC patterns with high accuracy in controlled studies, but they are research tools\u2014not replacements for medical evaluation.<\/p>\n

        Should I worry about every new smell I notice?<\/strong>
        \nNot at all. Temporary changes from food (like garlic or asparagus) are norm<\/p>\n

        al. Only persistent odors that last weeks and don\u2019t respond to hygiene improvements warrant attention.<\/p>\n
