Sympathectomy and parasympathectomy leads to the hyperfunction of the serotoninergic system and pathology

We studied the balance of activity of sympathetic, parasympathetic, and serotoninergic divisions of the autonomic nervous system in the regulation of the heart function in rabbits. High activities of the sympathetic and parasympathetic system are associated with antagonistic interactions between them. Moderation of activity of these systems could be accompanied by activation of the serotoninergic system. Physiological sympathectomy and parasympathectomy lead to hyperfunction of the serotoninergic system and pathology.

Side effects and complications of surgery for hyperhidrosis.

Dumont P.

Most of the difficulties associated with hyperhidrosis surgery are due to unavoidable side effects and unforeseeable and unacceptable complications. Careful patient selection is important before surgery so surgeons can avoid some of these pitfalls.

Patients should also be fully informed of all potential side effects and complications before surgical treatment.
