Iron and the Intestinal Microbiome.

Area of Science:

• Gastroenterology
• Microbiology
• Nutritional Science

Background:

• Iron is essential for physiological functions like oxygen transport and energy production, crucial for treating anemia.
• Excess or unabsorbed iron disrupts gut homeostasis, promotes pathogen growth, dysbiosis, and inflammation.
• Maintaining gut iron homeostasis is a complex interplay between the host and gut microbiota.

Purpose of the Study:

• To explore the dual role of iron in the gut.
• To understand the mechanisms of host-microbiota iron balance.
• To identify therapeutic strategies for managing iron-related gut issues.

Main Methods:

• Review of current literature on iron metabolism in the gut.
• Analysis of host-microbiota interactions concerning iron.
• Evaluation of emerging therapeutic approaches for iron dysregulation.

Main Results:

• Iron's essential role versus its detrimental effects when in excess.
• Gut microbiota and host strategies for iron homeostasis.
• Identification of therapeutic targets to mitigate iron-induced gut inflammation.

Conclusions:

• Balancing iron absorption is critical for gut health.
• Disrupted iron homeostasis exacerbates intestinal inflammation and disease.
• Novel therapies can enhance iron absorption while minimizing adverse effects, improving gut health.
