High blood creatinine 110μmol/L is considered to be related to physiological factors such as excessive meat consumption, strenuous exercise, or pathological conditions such as renal failure. Patients should pay attention to light diet, balanced diet, etc. For patients with renal failure, attention should also be paid to reduce the intake of high-potassium and high-phosphorus foods. 1. Physiological factors: For some patients who consume too much meat food or participate in strenuous activities before the examination, it may cause blood creatinine 110μmol/L, and usually the examination results are not clinically significant. This kind of patients can normalize their blood creatinine after adjusting their diets, such as paying attention to light, easy-to-digest foods and eating more fresh fruits and vegetables. 2. Pathological conditions: Acute or chronic renal failure can cause patients to have blood creatinine 110μmol/L. For patients with renal failure, they should have a blood creatinine of 110μmol/L in their daily life. For patients with renal failure, the daily diet should be high in calories, high in vitamins and easy to digest. It is worth noting that patients should avoid eating foods rich in potassium and high in phosphorus, and limit the intake of protein. If renal failure is accompanied by edema and heart failure, the amount of water intake should be strictly limited to avoid aggravating the condition. It is recommended that people with blood creatinine of 110μmol/L should go to regular hospitals for further detailed examination, and follow the doctor’s instructions after clarifying the cause of the disease, as well as paying attention to the reasonableness of their diets in their daily life.
