CCKstands forCholecystokinin
Full Form of CCK
What is CCK?
Cholecystokinin (CCK) is a peptide hormone produced in the I-cells of the duodenum and jejunum, primarily responsible for stimulating the digestion of fats and proteins. In the Indian medical education system, CCK is a standard topic in human physiology, especially for NEET and AIIMS entrance exams. It triggers the contraction of the gallbladder to release bile, stimulates pancreatic enzyme secretion, and acts as a satiety signal in the brain, reducing appetite. This hormone is also involved in gastrointestinal motility and is often studied alongside secretin and gastrin. In clinical practice, CCK levels are measured in cases of suspected pancreatitis or gallbladder dysfunction. Its role in regulating hunger makes it relevant to obesity research, which is gaining attention in India due to rising lifestyle diseases. Medical students in India encounter CCK in textbooks and practical physiology classes, and it is frequently asked about in competitive examinations. Understanding CCK is essential for doctors treating digestive disorders, as abnormalities can lead to indigestion, gallstones, or malabsorption.
