How much gastric fluid is produced daily?

• A. 1-2 L
• B. 0.5-1 L
• C. 3-4 L
• D. 2-3 L

Answer: (D)

Gastric juice production is quite large, designed to prepare and process food in the stomach. The stomach secretes a fluid rich in acid (HCl), enzymes like pepsin, and protective mucus, and over the course of a day this adds up to several liters. In a typical adult, about 2 to 3 liters of gastric juice can be produced daily, with secretion increasing after meals due to neural (vagal) stimulation and hormonal signals (gastrin). This volume supports digestion, mixing with food, and mucosal protection. While some secretion occurs even when fasting, the overall daily output remains in the 2-3 liter range, which is why that option is the best choice. The other amounts are outside the usual daily total for a healthy adult.
