This allows the stomach to expand, therefore increasing the volume of the stomach without increasing pressure. [2] They also provide the stomach with an increased surface area for nutrient absorption during digestion. [2] Gastric folds may be seen during esophagogastroduodenoscopy or in radiological studies.
