Introduction: A chronic or recurrent pain and discomfort in the upper abdomen occurs frequently in depressive patients. The pathogenesis of these symptoms is complex and not fully understood. The aim of the study was to estimate the gastric myoelectrical activity in this group of patients. Material and methods: The study group consisted of 90 subjects, including 71 women and 19 men (mean age – 38.0±8.1). Among them three groups were divided: healthy subjects (K, n=30), depressive patients with dyspepsia (group II, n=30) and depressive patients with Helicobacter pylori infection (group III, n=30). All the subjects completed Hamilton Depression Scale and the gastric myoelectrical activity examination with Polygraph–Medtronic A/S (Denmark) was done before and after a liquid meal for 120 minutes. Results: Preprandial normogastria in depressive patients (group II, III) compared to healthy subjects (group K) was lower 79.5±8.1% vs 73.6±8.7% (p<0.01) and 79.5±8.1% vs 68.4±9.9 (p<0.001). The similar differences were recorded during postprandial time. Power ratio scale (PR) was also lower in depressive patients than in healthy subjects: 3.5±0.7 (K), 1.6±0.7 (group II), 1.7±0.8 (group III) – p<0.001, p<0.001 respectively. Conclusions: In depressive patients gastric myoelectrical activity is disturbed and probably causes chronic dyspepsia symptoms.

In postmenopausal women various psychosomatic disorders concerning mood and appetite occur. The reason is not only estrogen deficiency, but also other hormones and neurotransmitters. The aim of the study was to estimate serotonin and melatonin levels and myoelectrical activity and gastric motor in postmenopausal women in relation to their nutritional status. The study was conducted in three 30-person groups of women: premenopausal (group I), postmenopausal with a normal body mass (group II), postmenopausal overweight (group III). Compared with group I, in group II there were no significant differences, while in group III serotonin level was lower respectively 156.5±40.2 ng/ml and 83.4±32.5 ng/ml (p<0.01), as well as the percentage of normogastria – 82.9±5.6% and 66.9±8.2 (p<0.05) and gastric emptying half-time 43.6±14.7 min and 27.4±12.2 min (p<0.01). Moreover, a negative correlation between body mass index and serotonin (r = -0.4744) and melatonin (r = -0.7146) levels was observed. The study results indicate the involvement of serotonin and melatonin in the pathogenesis of eating disorders in postmenopausal women.

U kobiet po menopauzie występują różnorodne zaburzenia psychosomatyczne, w tym dotyczące nastroju i łaknienia. Przyczyną tego jest niedobór estrogenów, ale także innych hormonów i neurotransmiterów. Celem badania było określenie stężenia serotoniny i melatoniny oraz czynności mioelektrycznej i motorycznej żołądka u kobiet po menopauzie w odniesieniu do ich stanu odżywienia. Badania przeprowadzono w trzech 30-sto osobowych grupach kobiet: przed menopauzą (grupa I), po menopauzie z prawidłową masą ciała (grupa II), po menopauzie ze współistniejącą nadwagą (grupa III). W porównaniu z grupą I, w grupie II nie stwierdzono istotnych różnic, natomiast w grupie III niższe było stężenie serotoniny, odpowiednio 156,5±40,2 ng/mL i 83,4±32,5 ng/mL (p<0,01), a także niższy był odsetek prawidłowej czynności mioelektrycznej żołądka (normogastrii) – 82,9±5,6% i 66,9±8,2 (p<0,05) oraz krótszy był czas połowicznego opróżniania żołądka (43,6±14,7 min. i 27,4±12,2 min.; p<0,01. Ponadto stwierdzono odwrotną zależność między wskaźnikiem masy ciała a stężeniem serotoniny (r = -0,4744) i melatoniny (r = -0,7146). Wyniki badań wskazują na udział serotoniny i melatoniny w patogenezie zaburzeń odżywiania u kobiet po menopauzie.
