Hypomagnesemia in short bowel syndrome patients.
BACKGROUND
Magnesium support to small bowel resection patients.


OBJECTIVE
Incidence and treatment of hypomagnesemia in patients with extensive small bowel resection.


METHODS
Retrospective study.


METHODS
Metabolic Unit of the University Hospital Medical School of Ribeirão Preto, University of São Paulo, Brazil.


METHODS
Fifteen patients with extensive small bowel resection who developed short bowel syndrome.


METHODS
Serum magnesium control of patients with bowel resection. Replacement of magnesium when low values were found.


RESULTS
Initial serum magnesium values were obtained 21 to 180 days after surgery. Hypomagnesemia [serum magnesium below 1.5 mEq/l (SD 0.43)] was detected in 40% of the patients [1,19 mEq/l (SD 0.22)]. During the follow-up period, 66% of the patients presented at least two values below reference (1.50 mEq/l). 40% increased their serum values after magnesium therapy.


CONCLUSIONS
Metabolic control of serum magnesium should be followed up after extensive small bowel resection. Hypomagnesemia may be found and should be controlled.
