Concept
Visceral hyperalgesia is a condition where there is an increased sensitivity to pain in the internal organs, often associated with functional gastrointestinal disorders like irritable bowel syndrome. It involves complex interactions between the central and Peripheral Nervous Systems, leading to an amplified pain response to normal visceral stimuli.
Functional gastrointestinal disorders (FGIDs) are a group of disorders characterized by persistent and recurring gastrointestinal symptoms without any identifiable structural or biochemical abnormalities. They are primarily diagnosed based on symptom patterns and are believed to arise from complex interactions between the gut and the brain, involving motility disturbances, visceral hypersensitivity, and altered mucosal and immune function.
Gastrointestinal physiology in children involves the maturation of digestive processes and the development of the gut microbiome, which are crucial for nutrient absorption and overall growth. Understanding these processes helps in diagnosing and managing pediatric gastrointestinal disorders effectively.
Concept
The microbiome, consisting of trillions of microorganisms residing in and on our bodies, plays a crucial role in maintaining health by influencing metabolism, immunity, and even behavior. Disruptions in the microbiome balance can lead to various diseases, highlighting its importance in both disease prevention and treatment strategies.

Imbalances in Gut microbiota are linked to various diseases, highlighting its importance in maintaining homeostasis and influencing metabolic, neurological, and immune functions.
Functional gastrointestinal disorders (FGIDs) are conditions characterized by chronic symptoms arising from the GI tract without any identifiable structural or biochemical abnormalities. They are often diagnosed based on symptom patterns and the exclusion of other organic diseases, with treatment focusing on symptom management and improving quality of life.
Concept
Intestinal motility refers to the contraction of the muscles in the gastrointestinal tract that facilitate the movement of contents through the digestive system. It is crucial for digestion, absorption of nutrients, and elimination of waste, and is regulated by a complex interplay of neural, hormonal, and muscular factors.
Concept
The vagus nerve, the tenth cranial nerve, plays a crucial role in the parasympathetic nervous system by regulating internal organ functions such as digestion, heart rate, and respiratory rate. It also facilitates communication between the brain and the gut, influencing mood and stress levels through the gut-brain axis.
Concept
Visceral sensation refers to the sensory experiences originating from the internal organs, often perceived as vague or diffuse, such as fullness, discomfort, or pain. These sensations play a crucial role in maintaining homeostasis by prompting reflexive actions and conscious behaviors to address internal physiological needs.
Concept
Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by abdominal pain and altered bowel habits without any identifiable organic cause. Though the exact cause is unknown, it is believed to involve a combination of gut-brain axis dysfunction, gut motility issues, and heightened visceral sensitivity.
