Hi Doctor, I am a male of 48.9 years. Height is 193 cm weight is 108 Kg. There were two blocks in my artery and I underwent angioplasty and implanted two stents in 2019 March. Since then I was controlling my food and walking 3 to 4 days a week for 60 to 66 minutes briskly. I was having Crestor 20 mg, Brillianta and aspirin 75. I managed to reduce my weight from 134Kg to 117 Kg. Cholesterol levels dropped to 90 and sugar was 96. Please note that I never had my sugar levels crossed 100. Since March 2020 I have started Keto diet. In two months, I have managed to reduce another 9 Kg and my current weight is 108Kg. Yesterday (02/05/2020), I did a blood test. Following attributes are showing high. Glycated Haemoglobin (HbA1c) is 6.30 (but fasting sugar is 94.50). Serum Cholesterol is 248.77 mg/dl Serum Triglycerides is 151.00 mg/dl Low Density Lipoprotein (LDL) in Serum is 178 mg/dl Creatinine in Urine is 279.4 mg/dl All other elements are within the normal reference range. Such as Albumin/creatinine ratio = 3.75 mg/g Albumin = 4.40 g/dl Alkaline Phosphate in Serum = 72.00 U/L Bilirubin (Total) in Serum = 0.80 mg/dl Bilirubin (Direct) in Serum = 0.09 mg/dl AST = 17 U/L ALT = 14.0 U/L I can understand that my cholesterol levels are going up due to the Keto diet. I am consuming fat as the energy source and I have stopped taking Crestor. My query is why is the creatinine level so high? Is it normal when we shift to ketosis?
