While poisons or certain foods cannot directly cause primary hyperhidrosis, understanding the distinction between primary and secondary hyperhidrosis helps clarify this question. Primary hyperhidrosis, which affects the majority of patients, stems from genetic factors and typically manifests in specific areas like palms, feet, underarms, or face without an underlying medical cause.
However, certain substances and foods can temporarily worsen existing hyperhidrosis symptoms. Spicy foods, caffeine, alcohol, and hot beverages may trigger increased sweating episodes in individuals who already have the condition. These triggers do not cause hyperhidrosis but can intensify symptoms during consumption.
