Twenty percent of our kidney disease patients are due to hypertension. Therefore, it is especially critical for hypertensive patients to know how to prevent hypertensive nephropathy. We will take a look at how to prevent hypertensive nephropathy in hypertensive patients today. How to prevent kidney function decline caused by hypertension? 1, be alert to increased nocturia: long-term hypertension damages the small blood vessels of the kidney, causing renal tubular dysfunction and causing increased nocturia. And this is an important signal of hypertensive nephropathy. Once patients get up more than two or three times at night, or even up to five or six times, they should rush to the hospital to do urinalysis, which often reveals abnormal microalbuminuria, which indicates that the kidney function has been slightly damaged and needs to receive treatment. Therefore, hypertensive patients should pay more attention to their urine, such as blood in the urine, foam, urine more often and other abnormalities, need to be extra vigilant. 2, according to personal circumstances to consume the right amount of protein: salt intake and blood pressure are closely related. To prevent hypertensive nephropathy, salt restriction is the most important, in addition, if there has been kidney damage, need to control protein intake under the guidance of doctors. Because too high protein intake will increase the burden on the kidneys, which in turn will aggravate the kidney damage; if the intake is insufficient, it will affect the body’s nutritional supply. Therefore, patients should decide the protein intake according to the kidney function status: when there is no obvious kidney function damage, the protein intake is controlled at about 50 grams per day; if there is abnormality, the protein intake should be reduced to 20 grams per day. 3, regular urine test: the first time hypertension is found, must do a comprehensive examination, especially with diabetes, coronary heart disease, hyperlipidemia, hyperuricemia and gout patients, clear whether there is no kidney damage. Patients with hypertension should also have regular urinalysis. If the initial kidney function check reveals no abnormality in the glomerular filtration rate, then a routine urine test and microalbumin test once a year is sufficient. If the glomerular filtration rate changes, we should shorten the frequency of the test according to the situation, such as once every six months in the early stage, and once every three months for further deterioration, and regularly monitor the kidney function in the nephrology department. Dietary considerations for patients with hypertensive nephropathy 1. Patients with hypertensive nephropathy should have a low-sugar diet. 2, hypertensive nephropathy patients should eat more calcium and potassium-rich foods. Such as kelp, lettuce, potatoes, eggplant, sour milk, shrimp, milk. Patients with hypertensive nephropathy should eat less broth, because broth contains increased nitrogen leachate, which can promote the increase of uric acid in the body and increase the burden on the liver, kidneys and heart. 3, hypertensive nephropathy patients should limit the intake of salt: daily should be gradually reduced to less than six grams. This amount refers to the amount of salt, including cooking salt and other foods containing sodium converted into the total amount of table salt. Appropriate reduction of sodium intake can help lower blood pressure and reduce sodium and water retention in the body. 4, hypertensive nephropathy patients should limit the intake of fat: when cooking, the choice of vegetable oil, can eat more sea fish, sea fish contains unsaturated fatty acids, can make cholesterol oxidation, thereby reducing plasma cholesterol, can also prolong the coagulation of platelets, inhibit thrombosis, prevent stroke, also contains more linoleic acid, to increase the elasticity of microvessels, prevent blood vessel rupture, prevent hypertension complications have a certain effect.
