Effect of obesity on erythrocyte count and hemoglobin levels in Libyan diabetic patients.

Fasting blood glucose, erythrocyte count and hemoglobin levels of obese and nonobese Libyan diabetic women were determined. The mean values of fasting blood glucose, erythrocyte count and hemoglobin of obese diabetic women were 209.55 +/- 8.85 mg/dl, 4.986 +/- 0.04 X 10(6)/mm3 and 14.51 +/- 0.18 g/dl. The respective values for nonobese diabetic women were 243.47 +/- 12.56 mg/dl, 4.865 +/- 0.06 X 10(6)/mm3 and 14.31 +/- 0.19 g/dl. The mean values of the three variables of obese patients were significantly different from those of the nonobese patients. Statistically significant correlations were found between fasting blood glucose levels and erythrocyte count, and hemoglobin levels in both obese and nonobese patients. The levels of erythrocyte count and hemoglobin of obese patients were higher than those of their nonobese counterparts. This elevation was attributed to the effect of obesity. It is suggested that regulation of body weight should be considered an essential step in the management of diabetes.
