This is the common name used for the appearance of sweat in other parts of the body after the sympathectomy is complete. Compensatory sweating, also known as (reflex sweating or compensatory hydrosis), can appear on the lower legs, thighs, abdomen, or the back.

Generally speaking, everything from the nipple line up will be dry after ETS. All patients will get some sort of compensatory sweating (compensatory hydrosis or reflex sweating) which does not necessarily have any correlation to the amount of hand sweating that occurred before the operation.

The majority of patients will experience it on a level that is acceptable to them, which we call mild to moderate. Between 3 to 5% of patients will get it on a severe level. The compensatory sweating (compensatory hydrosis or reflex sweating) is a byproduct of the operation, regardless of the method used.

    Do you have a treatment option for someone that had ETS 10 years ago and suffers from severe CS? Please let me know. I have heard about SDLA but want to know more about it

    Thank you.

      Dear Jake,
      One of the most common side effects from ETS is compensatory sweating. If the operation was performed with the clamping method, there is always a possibility of removing the clamps, therefore allowing for possible improvement for the compensatory sweating. If the sympathectomy was done with the incisional method (cutting method), the intercoastal nerve grafting is a possibility as well. In order to know about your situation, you need to discuss with a surgeon. We are happy to discuss further. Please contact our office and we can answer these questions for you once we have more information. Thank you.
