Aside from being a social stigma, obesity is frequently associated with insulin resistance, in turn linked to development of type II diabetes, hypertension, hyperlipidemia, and atherosclerosis – the so-called metabolic syndrome.This study investigated the biochemical changes in serum urea and creatinine levels in obese male rats treated with aqueous ginger extract. Forty age-matched adult male wister rats (90-110) gm were divided into four groups of ten rats each: Group I, Control group; Group II: Obese group. Group III: Low ginger dose (200 mg/kg body weight) treated obese group; Group IV: High ginger dose (400 mg/kg body weight) treated obese group.The obese group exhibited hyperglycemia accompanied with increasing in serum levels of Triglycerides (TG), Low Density Lipoprotein Cholesterol (LDL-C), Total Cholesterol (TC) levels. On the other hand, there was a significant reduction in High Density Lipoprotein Cholesterol (HDL-C) level. Ginger was effective in lowering all previous mentioned biochemical parameters and HDL-C level was increased significantly. Serum urea and creatinine levels showed a significant increase in obese rats. Otherwise, obese rats treated with ginger at either dose revealed a significant decrease as compared to obese group. These results indicated that the hypoglycemic and hypolipidemic effects of aqueous ginger extract (200, 400 mg/kg/day) could ameliorate obesity related kidney dysfunction.
