Pathogeny analysis of 168 iron-deficiency anemia cases

Objective To analyze and summarize the main pathogeny of iron-deficiency anemia （IDA）. Methods A retrospective analysis was made on the clinical data of 168 patients with IDA. Results The pathogeny of the 168 IDA cases included 9 cases with chronic gastritis （5.36%）, 21 cases with peptic ulcer （12.50%）, 8 cases after gastrectomy （4.76%）, 13 cases with gastric carcinoma （7.74%）, 23 cases with malnutrition （13.69%）, 5 cases with hemorrhoidal bleeding （2.98%）, 6 cases with liver cirrhosis hypersplenism （3.57%）, 1 case with gastric polyps （0.60%）, 1 case with gastric volvulus （0.60%）, 1 case with gastric stromal tumor （0.60%）, 3 cases with alimentary tract hemorrhage （1.79%）, 1 case with breast cancer （0.60%）, 11 cases with hypermenorrhea （6.55%）, 22 cases with uterine fibroid （13.10%）, 18 cases with long-term medication for connective tissue diseases （10.71%）, 1 case with congenital heart disease （0.60%）, 1 case with hyperthyroidism （0.60%）, 2 cases with intermittent nasal gums bleeding （1.19%）, 16 cases with unknown causes （9.52%）, and 5 cases with hematological system diseases （2.98%）. Conclusion There are 68 cases with disease of digestive tract, which account for 40.48%, as the main pathogeny of IDA. Chronic gastritis, peptic ulcer, and gastroenteric tumor are the main diseases. There were 33 cases with hypermenorrhea, accounting for 19.64%, and it is the main pathogeny in women. Hemorrhoids, intermittent nasal gums bleeding, and long-term medication for connective tissue diseases are the common pathogeny of IDA.
