Psychoautonomic disorders particularities in IBS patients according to bowel habit We studied the psychoautonomic disorders in 40 irritable bowel syndrome (IBS) patients, which were classified as IBS with diarrhea (IBS-D), with constipation (IBS-C), and mixed (IBS-M). The patients with IBS-D showed higher values of the Autonomic Profile, but the patients with IBS-M – lower values. Neurovegetative dystonia symptoms, including hyperventilation, were more pronounced in patients with IBS-D. Also, neuromuscular hyperexcitability was more expressed in IBS-D patients. The pathophysiological mechanisms of IBS subtypes are little known, they remain to be investigated further.

În această lucrare au fost studiate tulburările psiho-vegetative la 40 pacienţi cu sindromul intestinului iritabil (SII), care au fost grupaţi în: SII cu predominarea diareei (SII-D), cu predominarea constipaţiei (SII-C) şi mixt (SII-M). Pacienţii cu SII-D au obţinut cele mai înalte valori ale Profilului Vegetativ-Motor, iar cei cu SII-M – cele mai mici. Simptomele distoniei neurovegetative, inclusiv hiperventilaţia, au fost mai pronunţate la pacienţii cu SII-D. De asemenea, hiperexcitabilitatea neuro-musculară a fost mai accentuată la pacienţii cu SII-D. Mecanismele fiziopatologice ale subtipurilor de SII sînt puţin cunoscute, ele rămîn a fi studiate ulterior.
