Introduction

Calabash chalk, a naturally occurring mineral consumed predominantly by pregnant women in Nigeria as a remedy for morning sickness, has drawn attention due to its potential effects on the gastrointestinal tract. This geophagic material is known to be made up of fossilized sea shells and can contain various toxic elements, including lead and arsenic. The study aimed to investigate the impact of Calabash chalk on the histomorphology of the gastro-oesophageal tract in Wistar rats, assessing the changes induced by its consumption over varying durations.

Histomorphological Changes Induced by Calabash Chalk

The study documented significant histological alterations in both the stomach and oesophagus of rats after treatment with a Calabash chalk suspension. In the stomach, pathological observations included mucosal edema, hemorrhage, and inflammatory cell infiltrates, which indicated a deterioration of the mucosal integrity. Similarly, in the oesophagus, there were notable changes such as hyperkeratosis, acanthosis, and koilocytic features, all of which point toward substantial distress within the mucosal layer. These findings suggest that Calabash chalk consumption may compromise the structural integrity of the gastro-oesophageal tract, potentially leading to further gastrointestinal complications.

Conclusion

The research findings underline the detrimental histological effects of Calabash chalk on the gastro-oesophageal tract, raising concerns about its safety as a remedy often utilized during pregnancy. The observed alterations, including edema and inflammation in the stomach and harmful changes in the oesophagus, suggest that the consumption of this widely used geophagic material carries risks that could lead to more severe pathophysiological conditions. Awareness of these potential health implications is crucial, especially for communities where the practice of consuming Calabash chalk is common.
