Core Tip

Core Tip: Asymptomatic small intestinal ulcers may cause anemia due to vitamin B12 absorption or iron utilization, but anemia can also be caused by other digestive diseases such as gastric ulcer or gastrectomy or other chronic wasting diseases. Establishing a link between anemia symptoms and asymptomatic ulcers in the small intestine requires more extensive data support and other auxiliary examinations. Case reports and small sample investigations are not enough to support this link.
