Creatinine cannot be lowered by eating vegetables. Different causes of creatinine increase have different treatment methods, physiological causes include strenuous exercise, etc., and pathologic causes include chronic nephritis, etc. 1. Physiological causes: Strenuous exercise, fever, large protein diet and other factors may lead to a transient increase in creatinine, and creatinine will decrease after eliminating the relevant factors. 2. Pathologic causes: (1) Diarrhea, dehydration and other causes lead to renal failure, followed by creatinine elevation can be rehydrated, if necessary, blood transfusion. (2) Drugs that cause creatinine elevation should first stop using drugs that cause kidney damage, and if the condition is serious, glucocorticoids such as prednisone should be used for treatment. (3) Mycoplasma infection, IgA nephropathy and other causes of creatinine increase need glucocorticoid shock therapy, or combined with immunosuppressive drugs such as cyclophosphamide for treatment. (4) Chronic nephritis, diabetic nephropathy, etc. may also lead to creatinine increase, which needs to be treated for the primary disease, such as reducing proteinuria and controlling blood sugar. Diabetic patients’ diet should reduce the intake of starch, rice, steamed bread to reduce the amount; avoid eating high potassium fruits and peanuts, melon seeds, etc.. When patients have elevated creatinine should go to the hospital in time, under the guidance of the doctor for treatment.
