was determined by slide test method.  
Result: Out of 60 PU patients 54 were males and 6 females. 18 had blood group O, 24 had group B, 11 had AB and 
7 had A blood group. 90% were Rhesus positive. O group was dominant (38.46%) in peptic ulcer patients with 
antral lesion. In patients having duodenal lesion, B group was prevalent (45.83%). Males were predominant 
sufferers (75%). The poor and middle class patients were equally affected. The ethnic group Pathan were more 
affected (36.67%) compared to Baloch and Hazara.

in blood group B. There is a high prevalence in Pathan males. Duodenal lesion is more prevalent compared to antral 
lesion.
