Hi, Thank you for your question. Bouts of excessive sweating can be a sign of the menopause. You do not mention whether you are female or your age. Another cause is hyperhydrosis which is a condition of abnormally increased sweating either generalized or localized to hands, feet, armpits and the groins. It can be triggered by caffeine, nicotine, spicy foods or alcohol. Treatment options include prescription antiperspirants or aluminium chloride applied at night. A dermatologist may offer botulinum toxin treatment. There are surgical treatments available for the most severe cases. I hope this has helped you. Regards.
