Patients with nephritis can eat milk powder. Patients with nephritis should have a low-salt, low-fat, high-quality and low-protein diet. Low-salt means avoiding pickled foods and foods with salty taste; low-fat means avoiding cholesterol and fat-rich foods; high-quality protein means protein rich in essential amino acids, mainly in kinetic proteins, and avoiding plant protein-rich foods as much as possible. Because plant protein contains less essential amino acids and more metabolic waste, which can increase the burden on the kidneys. Milk powder belongs to animal protein, can eat, but need to limit the intake. If you have nephritis, you should actively control your blood pressure and reduce proteinuria, if proteinuria＞1g/24h, your blood pressure should be controlled below 125/75mmHg; if proteinuria＜1g/24h, your blood pressure should be controlled at 130/80mmHg. If there are indications for renal biopsy, we recommend renal biopsy to clarify the pathological type, and hormone and immunosuppressant treatments are chosen according to the pathological type. Chronic nephritis is a chronic progressive disease, until the end stage of renal failure, uremia stage, once the symptoms of uremia appear, such as nausea, vomiting, or even upper gastrointestinal bleeding, chest tightness, shortness of breath, dyspnea, renal replacement therapy, hemodialysis or peritoneal dialysis treatment.
