Question 1

What is the Meaning of Gastroparesis?

Accepted Answer

Gastroparesis is a chronic condition defined by delayed gastric emptying, where food remains in the stomach abnormally long without mechanical obstruction. Impaired gastric contractions hinder proper movement of contents into the small intestine, leading to digestive disturbances and impacting nutrient absorption.

Question 2

What is the Context of Gastroparesis?

Accepted Answer

This disorder operates within the gastrointestinal system, impacting stomach motor function. Normal gastric emptying relies on coordinated contractions governed by vagus and enteric nervous systems. Gastroparesis often stems from damage or dysfunction of these neural pathways, commonly seen in diabetes mellitus, post-surgical complications, or as an idiopathic presentation.

Question 3

What is the Significance of Gastroparesis?

Accepted Answer

In a clinical setting, gastroparesis significantly impacts patient well-being. Its presence complicates glycemic control in diabetic patients, as delayed food absorption makes insulin dosing challenging. Diagnosis involves evaluating persistent symptoms like chronic nausea, vomiting, early satiety, and bloating, which diminish quality of life and affect medication efficacy.

Question 4

What is the Mechanism of Gastroparesis?

Accepted Answer

The mechanism of gastroparesis involves impaired neural and muscular coordination within the gastric wall. Vagus nerve damage disrupts normal peristaltic waves essential for propelling food. This neuropathy can lead to dysfunction of interstitial cells of Cajal, pacemaker cells coordinating gastric smooth muscle contractions. Consequently, stomach emptying into the duodenum is compromised.

Question 5

What is the Application of Gastroparesis?

Accepted Answer

Managing gastroparesis in clinical practice involves a comprehensive, individualized approach. Dietary modifications, such as small, frequent meals low in fat and fiber, are fundamental. Pharmacological interventions often include prokinetic agents, like metoclopramide, to stimulate gastric motility, alongside antiemetics. For refractory cases, gastric electrical stimulation may be considered.

Question 6

What is the Metric of Gastroparesis?

Accepted Answer

The definitive diagnostic metric for gastroparesis is gastric emptying scintigraphy (GES), a nuclear medicine test quantifying the rate food leaves the stomach over four hours. Other diagnostic tools, such as the wireless motility capsule, assess gastric emptying time. Clinical assessment also incorporates symptom severity scales, like the Gastroparesis Cardinal Symptom Index (GCSI), to measure symptom impact and treatment response.

Question 7

What is the Risk of Gastroparesis?

Accepted Answer

Untreated gastroparesis poses several clinical risks. Persistent vomiting and poor oral intake can lead to dehydration, electrolyte imbalances, and malnutrition. Erratic carbohydrate absorption, particularly in diabetic individuals, increases the risk of unpredictable hypoglycemia or hyperglycemia, complicating disease management. Long-term complications can include bezoar formation, requiring intervention.
