Nephrotic syndrome is a clinical subtype of chronic kidney disease. It can be diagnosed when there is significant proteinuria, hypoalbuminemia, accompanied by edema and hyperlipidemia. This represents a severe stage in the progression of kidney diseases, generally requiring treatment with steroids and immunosuppressants. Nephrotic syndrome may have complications such as thrombosis, infections, hyperlipidemia, and acute renal failure.

How should you eat with nephrotic syndrome?

Nephrotic syndrome is characterized by urine protein greater than 3.5 grams, serum albumin less than 30, the presence of edema, and hyperlipidemia. Patients matching these criteria can be diagnosed with nephrotic syndrome. From its diagnosis, we can see that such patients have a high amount of urine protein and relatively low blood protein. For these patients, it is necessary to control their protein intake, generally suitable at 0.6-0.8 grams per kilogram of body weight per day. Due to hypoalbuminemia, as the liver synthesizes protein, it also leads to an increase in blood lipids. Therefore, patients with nephrotic syndrome need to follow a low-fat diet to avoid further elevation of blood lipids. Additionally, as patients with nephrotic syndrome generally have edema, it is necessary to restrict sodium intake to prevent sodium and water retention, further aggravating the edema.

Does nephrotic syndrome require a puncture?

Nephrotic syndrome is a complex of clinical symptoms with various causes, which differ by age group. In children or adolescents, if it presents solely as significant proteinuria without elevated creatinine or hematuria, it is generally caused by minimal change disease. Since this type of kidney disease is sensitive to hormone treatment, it is usually possible to forego renal biopsy and start with corticosteroid therapy. For other nephrotic syndrome patients, it is advisable to first perform a renal biopsy to identify the pathological cause before considering appropriate treatment with hormones, immunosuppressants, and other medications.

Characteristics of Nephrotic Syndrome

The characteristics of nephrotic syndrome are defined by significant proteinuria, where significant proteinuria refers to urinary protein exceeding 3.5 grams in 24 hours; hypoproteinemia, which refers to blood albumin levels below 30 grams per liter; edema, which may present in facial and lower limbs, and even severe patients may exhibit generalized edema around both lower limbs; and hyperlipidemia, characterized by increased cholesterol and triglycerides in the blood. These patients may exhibit reduced urine output, edema, and noticeably increased foam in the urine.

What should not be eaten with nephrotic syndrome?

Patients with nephrotic syndrome, if the patient has obvious edema, should limit salt intake to between two to three grams per day. It is suggested to consume foods rich in polyunsaturated fatty acids, such as vegetable oils, as well as foods rich in soluble fiber, such as oats. They should also receive a normal amount of 0.8 to 1 gram of high-quality protein per kilogram of body weight per day, mainly from egg whites, milk, lean meat, and fish. Calorie intake should be sufficient, and patients with nephrotic syndrome should eat less salty and pickled foods and consume less animal fat.

Precursors of relapse of nephrotic syndrome

Nephrotic syndrome is characterized by patients having 24-hour urinary protein quantification exceeding 3.5g and blood plasma albumin levels lower than 30g/L. This condition can be long-lasting. Some patients, after treatment, can have their condition effectively controlled, but there is still a possibility of relapse. Such relapses often occur after the patient has been overworked or has caught a cold, but there are also some patients who do not have such triggers. When the condition relapses, the urinary protein level increases again, which might lead to an increase in urine foam. Patients might experience significant swelling in the lower limbs and face among other areas, suggesting a relapse of nephrotic syndrome, and it is important to go to the hospital for relevant tests promptly.
