The short- and long-term outcome of donations from living donors of kidneys (LKDs) remains controversial. Information regarding metabolic changes after donation in Malaysia remains limited despite Malaysia having the highest record prevalence of diabetes, obesity, and hypertension in Asia. There were 159 LKDs in our center from 2010 to 2020. We analyzed pre and post donation clinical data and laboratory results from 140 LKDs, retrospectively, from electronic medical records and looked for any metabolic changes. Among these 140 LKDs, 99 were women (70.7%), with a mean age of 47.23 +/- 11.67 before donation. The median follow-up was 4 years (range, 2-6 years). Median body mass index increased from 24.35 kg/m(2) (range, 22.11-26.93) to 25.56 kg/m(2) (range, 22.78-28.57; Z=-3.934, P = .000) after donation. Prevalence of obesity increased from 24.18% to 30.77%. Only 2.8% of LKDs developed proteinuria postnephrectomy (P = .250). Serum creatinine increased from 60 mmol/L (range, 52-74) to 87 mmol/L (range, 74-108) 1 year after donation (P = .000), and the latest results decrease to 83 mmol/L (range, 73-101; P = .000). Systolic blood pressure increased from 127.83 +/- 12.25 mm Hg to 131.30 +/- 18.16 mm Hg, (t 97] = -2.012; P = .047); and prevalence of hypertension increased from 19.81% to 23.58% (P = .125), with 22.64% requiring treatment. We noted that 22.54% of the LKDs had dyslipidemia before donation, a number that increased to 50% after donation (P = .000). LKDs with hyperuricemia increased significantly from 7.92% to 34.65%, with uric acid level increasing from 311.94 +/- 78.51umol/L to 381.87 +/- 86.96 umol/L (t94] = -10.805; P = .000). Fasting blood glucose and glycated hemoglobin level recorded no significant changes after donation. Post donation kidney function of LKDs compensated well and stable in short term. We noted statistically significant increment of weight, post donation body mass index, systolic blood pressure, uric acid, and lipids. We suggest prospective studies with longer follow-up and more subjects for clinical correlation.
