Causes and Treatments for Sweaty Feet
Plantar Hydrosis is the medical term for sweaty feet. This condition is described as excessive sweating of the soles of the feet. This condition also occurs underneath the armpits (axillary hyperhydrosis). This condition can also occur in the palms of the hands (palmer hyperhydrosis). Sweaty feet has been found to occur in over 5% of the U.S. population, with varying levels of severity.
There are no known obvious causes of hyperhydrosis, although it is known that it is mediated through the sympathetic nervous system. The cause of sweat overproduction may be due to runaway firing of synapses in the sympathetic nervous system or by over secretion of the sweat glands themselves. Genetics and heredity have been determined to be contributing factors in the prevalence of sweaty feet.
Symptoms
The obvious symptom of plantar hyperhydrosis is excessive sweating on the soles of the feet. This state may be brought on by anxiety, stress, athletic activity and changes in one's emotional state. Some occurrences of sweaty feet may have no precipitating event.
The condition of sweaty feet may present itself as a mild case and be none other than annoying or just a little uncomfortable. On the other hand, severe instances of foot sweating can lead to severe foot odor (bromhydrosis). Severe cases of sweaty feet can be a precursor to skin problems in the top or bottom of the feet. Circumstances such as athlete's foot (tinea pedis), fungal toenails (onychomycosis), bacterial infections (staph or strep impetigo) and many forms of dermatosis can cause or be worsened by severe cases or hyperhydrosis.
