Blood Type Group O Associated With Higher Rates of Post-Tonsillectomy Bleeding

In the July 2010 volume of International Journal of Pediatric Otorhinolaryngology, researchers in Ireland published an interesting finding that 63% of bleeding after tonsillectomy were in patients with Blood Type O. The general population Blood Type O is only 55%.

Although the authors were careful to state that this finding does not demonstrate causality, this association does suggest that patients with Type-O blood are more likely to suffer from secondary bleeds following tonsillectomy.

The other blood types are A, B, and AB.
