Sweaty Feet (Hyperhidrosis)
Sweaty feet can be uncomfortable and embarrassing. They can also lead to other problems, such as fungal infections, splits between toes, and smelly feet, where bacteria feed on sweat and dead skin cells.
Living on our skin are various bacteria and fungi which help us fight infections and keep our skin healthy. Sometimes there are changes in our skin that alter its pH which makes it less acidic. This leads to an imbalance of the bacteria and fungi and they cause the sweat and skin on our feet to smell.
Primary hyperhidrosis is excessive sweating, usually of the armpits, hands and feet. It is linked to over activity in the sympathetic nervous system, specifically the thoracic sympathetic ganglion chain which runs along the vertebra of the spine inside the chest cavity. This chain controls the apocrine and eccrine glands which are responsible for perspiration throughout the body. However the reason for this over activity is not known.
Secondary hyperhidrosis is caused by other conditions such as hyperthyroidism, obesity, menopause, psychiatric disorders, infection, and medication or injury induced.
The cause of excessively sweaty feet can be investigated via your GP.
