The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.
Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

peripheral sympathectomy causes a dramatic increase in NGF levels in the denervated organs

Increased Nerve Growth Factor Messenger RNA and Protein

Peripheral NGF mRNA and protein levels following
sympathectomy
It has been shown previously that peripheral sympathectomy
causes a dramatic increase in NGF levels in the denervated
organs

Compensatory sweating is not compensatory

Does compensatory sweating only happen to hyperhidrosis patients who underwent ETS?

The exact reason for compensatory sweating is yet to be determined. There are some physiological explanations for that but none are yet completely proven. The reason for this statement is that compensatory sweating happens in a mild, moderate or a higher level of sweating. The fact that not everyone responds in the same way to the hyperhidrosis operation points to the unknown nature of this problem. More than that patients who underwent thoracic sympathectomy for reasons OTHER than hyperhidrosis also develop compensatory sweating in different intensities. This last statement shows that compensatory sweating happens to both hyperhidrosis patients and non-hyperhidrosis patients who have undergone the surgery.

Sympathectomy reduces emotional, stress-induced sweating indicating that it affects the stress-response


"...for reasons that are not obvious, many patients with facial hyperhidrosis and hyperhidrosis of the feet will benefit from upper thoracic sympathectomy. " 

(The Journal of Pain, Vol 1, No 4 (Winter), 2000: pp 261-264)

"Bilateral upper thoracic sympathicolysis is followed by redistribution of body perspiration, with a clear decrease in the zones regulated by mental or emotional stimuli, and an increase in the areas regulated by environmental stimuli, though we are unable to establish the etiology of this redistribution." 

(Surg Endosc. 2007 Nov;21(11):2030-3. Epub 2007 Mar 13.) 


"Palmar hyperhidrosis of clinical severity is a hallmark physical sign of many anxiety disorders, including generalized anxiety disorder, panic disorder, posttraumatic stress disorder, and especially social phobia.4 These are increasingly well understood and highly treatable neurobiological conditions. They are mod- erately heritable hard-wired fear responses,5 and are linked to amygdalar and locus coeruleus hyper-reactivity during psycho- social stress.6,7 Anxiety disorders are known to be much more common among women. This is consistent with the finding of Krogstad et al. that among controls sweating was reported more often by men, while among the hyperhidrosis group sweating was reported more often among women."

"A surgical treatment for anxiety-triggered palmar hyperhidrosis is not unlike treating tearfulness in major depression by severing the nerves to the lacrimal glands. We have recently made a similar argument advocating a psychopharmacological, rather then a surgi- cal, first-line treatment for blushing.9"
