Introduction
Calabash chalk, a geophagic material predominantly consumed by pregnant women in Nigeria and other parts of sub-Saharan Africa, contains a mixture of clay and minerals, including potentially harmful elements. This study aimed to understand the effects of calabash chalk on the histomorphology of the fetal cerebral cortex in gestating Wistar rats. Existing literature has reported adverse health impacts attributed to the consumption of this substance, underscoring the need for empirical research on its effects during pregnancy, particularly on fetal development.
Impact on Fetal Development: Weight and Histomorphology
The findings revealed that foetuses exposed to calabash chalk exhibited significantly higher mean body weights compared to the control group, indicating possible nutritional or metabolic influences from the chalk. Furthermore, histomorphological analysis of the fetal cerebral cortex indicated hypertrophy and hyperplasia of cells across all cortical layers in the chalk-exposed group. While no gross malformations were observed, the increases in cellular population density and changes in Nissl substance staining suggest potential disruptions in neuronal integrity and overall brain development. These alterations highlight the risks associated with heavy consumption of calabash chalk and its components during pregnancy, as they may significantly affect the development and functionality of the fetal brain.
Conclusion
In conclusion, this study indicates that maternal consumption of calabash chalk can lead to increased fetal body weight and significant histomorphological changes in the cerebral cortex. The presence of minerals in calabash chalk that can cross the placental barrier raises concerns about their potential long-term effects on cognitive and neurological development after birth. Therefore, further research and awareness are crucial to address the health implications of geophagy in pregnant women and to provide guidance on safe practices concerning the consumption of substances like calabash chalk.
