                                According to research, primary adult-type hypolactasia—a form of disaccharidase deficiency—affects approximately 70% of the world's population, making it the most common form. This condition, along with other disaccharidase deficiencies, results from the reduced activity of crucial enzymes in the small intestine needed to break down specific sugars.
