Magnesium status and gastric function: experimental and clinical data

Area of Science:

• Gastroenterology
• Cell Physiology
• Nutritional Science

Background:

• Magnesium is a vital intracellular cation involved in numerous cellular processes.
• Its role in gastric physiology, particularly in relation to acid secretion and motility, is complex and multifactorial.
• Understanding magnesium's impact on gastric function is crucial for addressing related diseases.

Purpose of the Study:

• To review the current understanding of magnesium's physiological, pharmacological, and clinical relevance to gastric function.
• To explore the intracellular mechanisms, specifically Ca(2+)-Mg2+ interactions, through which magnesium modulates gastric activity.
• To examine the association between magnesium status disturbances and gastric pathologies such as ulcer and cancer.

Main Methods:

• Literature review of physiological, pharmacological, and clinical studies.
• Analysis of intracellular signaling pathways involving calcium and magnesium.
• Synthesis of data on magnesium's role in acid secretion and gastric motility.
• Examination of epidemiological and clinical data linking magnesium status to gastric diseases.

Main Results:

• Magnesium significantly modulates gastric acid secretion and motility through intracellular signaling pathways.
• Intracellular calcium-magnesium interactions are key targets for magnesium's physiological effects in gastric cells.
• Disruptions in magnesium status are implicated as a pathophysiological factor in gastric ulcer and cancer development.

Conclusions:

• Magnesium is a critical regulator of gastric function, impacting both acid secretion and motility.
• Imbalances in magnesium status represent a potential risk factor and therapeutic target for gastric diseases.
• Further research into magnesium's role in gastric health is warranted.
