Chronic kidney disease patients with declining kidney function, doctors will tell them to low protein diet, most patients often think that they have to start limiting meat, egg yolk, etc., and even many things are too scared to eat, patients communicate with each other after we all do so, in this way, most patients often over-restricted, eating has not only become a very boring thing, but also, worrying emotions plague patients, and It also seriously affects the group he belongs to, his family and even his unit, with the long-term consequence of weakness in the limbs and accelerated deterioration of kidney function. For such patients, professional dietary guidance from a nephrologist is extremely important: Individuals with chronic kidney disease vary greatly, and the dietary management plan suitable for patient A may not be suitable for others. Therefore, it is recommended that there is really no need to follow other patients in terms of diet management between patients, but always go to your nephrologist for a diet management plan that suits you. This step is very important, which requires you to write down in detail the type of food you eat at each meal and also record the amount of food accurately, therefore, you should have a kitchen scale at home. Therefore, you must not eat in a big way as before. After visiting a nephrologist, your meals must be carefully managed with the doctor. After checking your recipes, the nephrologist will analyze your diet, calculate your daily calories and composition of protein, carbohydrates, fat, phosphorus, salt and water, analyze whether your dietary structure is reasonable according to the data, and then make professional corrections. After the nephrologist gives you professional dietary guidance, there is one more task that is also very important, that is, you are required to make regular follow-up visits, usually once a month for the first six months after the first adjustment of the diet plan, with the purpose of making changes to the diet plan according to your condition at any time. Diet and nutritional management is no longer an unappreciated measure for patients with chronic kidney disease, but has now been elevated to the purpose of treatment, and should be renamed as diet and nutritional therapy (GNT) for chronic kidney disease, together with drug therapy, to play a role in delaying the progression of kidney function. It is a lifelong management process that requires the lifelong advice and guidance of a nephrologist.
