Hi, my husband is 48 yrs old, 205lbs, and he was diagnosed habing CKD last 2008, he creatinine level within 3 years range from 1.8 to 3.2 , then last july 15, 2011, his creatine lab result is 4.7 and his hemoglobin becomes 112 comparing last month 134. According to her neprologist, he is in the stage 3 category. He is also a hypokalemic since 2002 due to gitelmans syndrome deasease. I am worried with my husband condition and he is very irritable and loose hope that he will be healed. Is there a medicine to lower fast his creatine? And what food and kinds of vegetables and fruits he should be eaten?
