Intestinal physiology and parasitic diseases

Area of Science:

• Gastroenterology
• Human Physiology
• Infectious Diseases

Background:

• Normal nutrition relies on intact alimentation, digestion, and absorption.
• Parasitic infections can negatively impact intestinal physiology.
• Understanding these interactions is crucial for public health.

Purpose of the Study:

• To review the effects of parasitic infections on human alimentation, digestion, and absorption.
• To discuss the mechanisms by which parasites influence intestinal physiology.
• To highlight the impact of parasites on nutritional status.

Main Methods:

• Literature review of studies on parasitic infections and intestinal physiology.
• Analysis of mechanisms of parasite-induced physiological changes.
• Synthesis of evidence on nutrient competition and mucosal damage.

Main Results:

• Parasites affect alimentation, digestion, and absorption through various mechanisms.
• Mechanisms include systemic toxicity, nutrient competition, mucosal damage, and altered motility.
• Parasitic infections most significantly impact food intake, the initial step of alimentation.

Conclusions:

• Parasitic infections pose a significant threat to normal nutrition.
• Interference with the alimentary process, particularly food intake, is a key impact.
• Further research is needed to mitigate the nutritional consequences of parasitic infections.
