Which complication can result from scar tissue developed during healing of a gastric ulcer?

Scar tissue that develops during the healing process of a gastric ulcer can lead to stenosis, which is a narrowing of the gastric lumen. This occurs because the scar tissue can be less flexible than healthy tissue and may cause the surrounding muscles of the stomach to constrict, limiting the passage of food and digestive materials. Stenosis can result in symptoms such as nausea, vomiting, and difficulty in the passage of food, leading to complications in digestion and nutrition.

While other complications like hemorrhage and perforation are serious and can occur due to ulcers, they are not primarily a result of the scar tissue formation. Instead, they are typically associated with the ulcer's tissue erosion and other underlying issues. Obstruction can also be a broad term that impacts gastric function, but stenosis specifically denotes the structural narrowing directly related to scar tissue formation from ulcer healing. Therefore, the accurate consequence of scar tissue from a gastric ulcer is stenosis.
