What is the impact of insufficient bile production on digestion?

Insufficient bile production primarily hampers the digestion and absorption of dietary fats. Bile, produced in the liver and stored in the gallbladder, contains bile salts that emulsify fats, breaking them down into smaller droplets. This process increases the surface area available for enzymes, such as lipase, to further digest these fats into absorbable fatty acids and glycerol.

When bile production is inadequate, fats are not adequately emulsified, leading to poor digestion and absorption. This can result in symptoms such as fatty stools and nutritional deficiencies, particularly in fat-soluble vitamins (A, D, E, and K), which rely on fats for absorption. Therefore, difficulty in digesting fats stems directly from insufficient bile affecting the emulsification process, making this the correct answer.
