question: Hi, My mom is 53yrs old, 5 ft tall and weighs 51 kgs. She s been taking medication for high blood pressure for past3-4 yrs. Her blood pressure is under control but recently her blood test has shown higher creatinine level (around 2.3) and higher urea level (100). Her potassium level was also high but is now under control. Sodium and phosphorus levels are normal Please suggest what diet she should follow to control these levels. Thanks
