To determine the relationship between tonsillitis, tonsillectomy and a
bnormalities in body weight, we have analyzed pre-and post-operative w
eights in a population of 55 children who underwent adenotonsillectomy
in our department. Pre-operative mean weight was 9.8% heavier than th
e standard mean normal weight for age and post-operative mean weight w
as 22% greater than standard mean weight for age. The mean weight gain
during the follow-up period was 12% greater than that which would be
normally expected (p < 0.001). This study suggests that children under
going tonsillectomy are slightly heavier than their peers and that fol
lowing the procedure this discrepancy increases. (C) 1997 Elsevier Sci
