When does the stomach function best?

• A. When full
• B. When one-third full
• C. When two-thirds full
• D. When empty

Answer: (C)

The stomach digests best when it has a moderate amount of content, enough to trigger strong, coordinated contractions that mix food with gastric juice, but not so full that it slows down emptying. When about two-thirds full, there’s enough distension to stimulate effective mixing and enzyme action, creating chyme efficiently while still allowing the stomach to continue moving its contents into the small intestine at a steady rate. If it’s empty, secretions and contractions aren’t as well organized, reducing digestion efficiency; if it’s too full, the stomach becomes stretched and emptying slows, which can hinder digestion and cause discomfort. So, two-thirds full strikes the right balance for optimal stomach function.
