Do neuroactive steroids cause fatigue in pregnancy?
1Department of Gynecology and Obstetrics, University Hospital, Zurich, Switzerland.
Summary
Pregnancy fatigue may be linked to neuroactive steroids. Researchers found a correlation between fatigue and these compounds in pregnant women, but not benzodiazepines.
Area of Science:
- Neuroendocrinology
- Reproductive biology
- Human physiology
Background:
- Fatigue is a common complaint during pregnancy.
- The underlying causes of pregnancy-related fatigue are not fully understood.
- Neuroactive steroids and benzodiazepines are known to influence mood and behavior.
Purpose of the Study:
- To investigate the potential role of endogenous neuroactive steroids and benzodiazepines in pregnancy-related fatigue.
- To correlate levels of these compounds with self-reported fatigue in pregnant women.
Main Methods:
- Plasma samples were collected from 23 healthy pregnant volunteers at various gestational ages.
- Receptor binding assays were used to measure endogenous neuroactive steroids, endozepines, and benzodiazepines.
- Participants reported their level of fatigue at the time of sample collection.
Main Results:
- A significant correlation was observed between pregnancy fatigue and the presence of neuroactive steroid-like activity.
- No endogenous benzodiazepine-like factors were detected in the plasma samples.
- The study identified a potential link between specific neuroactive steroids and fatigue during gestation.
Conclusions:
- Neuroactive steroids may play a role in the development of fatigue during pregnancy.
- The precise origin and biological function of these neuroactive steroids in pregnancy require further investigation.
- Endogenous benzodiazepines do not appear to be a significant factor in pregnancy-related fatigue based on this study.
