Association Between Hypomagnesaemia and Foot Ulcers in Type II Diabetes Mellitus

Abstract

Objective: The aim of the study was to seek the association between hypomagnesaemia and foot ulcers in type II 
diabetes mellitus and to verify the effect of age, sex, grades of ulcer, duration of ulcers and duration of diabetes and 
presence of hypomagnesaemia in the association with type 2 diabetes mellitus. 
Study Design: cross sectional study. 
Place and Duration of Study: This study was carried out in the indoor, setting of Medical Department Peoples 
Medical College Hospital Nawabshah from September 2009 to May 2010. 
Samples: The subjects were divided into two groups. One was with Grade-I Diabetic foot ulcer and the other with 
Grade-II diabetic foot ulcers with type II diabetes mellitus. Both the groups contained 50 subjects each and were 
selected according to the inclusion and exclusion criteria. 
Materials and Methods: After a brief interview of 100 patients regarding age, sex, duration of Type II diabetes 
mellitus, duration of foot ulcer and grade of foot ulcer, both groups underwent fasting serum Magnesium level and 
categorized on the basis of foot ulcers Grade-I and Grade-II according to Wagner’s classification of diabetic foot 
ulcers. 
Results: Chi – square test was applied to see the association and then odds ratio was calculated to check the strength 
of association. Out of 100 Type II diabetic patients, hypomagnesaemia was detected in 20 with grade I diabetic foot 
ulcer and in 37 patients with grade II diabetic foot ulcers having chi-square value of 13.071 and significance of 
0.000 with likelihood ratio 13.554.  
Conclusion:  There is strong association between hypomagnesaemia in foot ulcers with Type II diabetes mellitus.
