Excessive sweating, also called hyperhydrosis, may be a hereditary condition, but may also be caused by stress, certain medications or other underlying conditions. The feet are a likely body area to sweat in excess, and this can be very unpleasant. There are a few ways to cure sweaty feet; some bring temporary relief while others are permanent.

1. Sympathectomy

Sympathectomy is a surgical procedure that will work on the sympathetic ganglia, and cut or remove these, to inhibit the excessive sweating. The sympathetic system is in charge of regulating sweating and other body functions, such as blood pressure.

The procedure takes up to 90 minutes and it is a permanent solution. The success rate of the therapy is over 90%; however, one possible side effect of the treatment is that you may experience excessive sweating in other areas (i.e. chest).

2. Percutaneous Radiofrequency Waves

If only one foot is affected by excessive sweating, percutaneous radiofrequency waves can be applied on the sympathetic ganglia, and the therapy should result in the inhibition of these nerves and the elimination of excessive sweating. This therapy should be applied for a few weeks, so that it can be fully effective.

3. Medications or Ointments

There are also a few medication treatments that may relieve excessive sweating. Drysol or Xerac AC is a prescription medication that contains aluminum chloride anhydrous ethyl alcohol. The solution can also be prepared by the pharmacist, according to the doctor’s indications. Typically, the aluminum chloride should be used in concentrations ranging between 6 and 20%. In some cases, when the sweating is severe, a higher concentration of aluminum chloride may be necessary.

Drysol, Xerac AC and similar solutions may cause skin irritation. Tannic acid solutions coupled with ethanol and formalin may also cure sweaty feet. Consult a doctor, as these medications and ointments are only available through prescription and they may also cause severe irritation.

4. Iontophoresis

Iontophoresis is a treatment that involves applying ionized medications on the skin, then penetrates it using currents. Even if this therapy is mostly used for palmar hyperhydrosis, it may be applied to the feet as well. The sweat glands will be inhibited, and they will produce less sweat.

5. Avoid Stress

If you know that stress causes you to sweat in excess, you should try to avoid situations that cause stress. This will cause less sweat.

Additional Tips to Reducing Sweat
