Patients with nephrotic syndrome should pay attention to maintenance because nephrotic syndrome is a chronic disease. Even if the condition is well controlled, it can still recur or worsen under certain circumstances. First and foremost, patients should avoid various inflammations, including infections of the upper respiratory tract, enteritis, skin infections, ulcers, etc. Patients should avoid getting cold, avoid contact with people who have colds, and wear masks in crowded places. Avoid eating raw, unhygienic food to prevent diarrhea and enteritis. Patients should also limit their salt intake, and it is recommended that their daily salt intake be controlled between 3 and 6 grams.

Do you take steroids for nephrotic syndrome?

Once nephrotic syndrome is diagnosed, corticosteroid therapy becomes a primary treatment, and the commonly used steroid is prednisone. If there is liver damage or the treatment effect of prednisone is not good, oral prednisolone or intravenous methylprednisolone can be used. Due to its long half-life and severe side effects, dexamethasone is now generally less used. The course of treatment with corticosteroids for nephrotic syndrome is relatively long, needing about one to one and a half years. During this process, the use of steroids has three phases: the initial full-dose phase, during which a relatively large dose of the hormone is used for about two to three months; the second phase is a slow reduction process; the third phase is a low-dose maintenance process. Overall, during the use of steroids, patients must regularly follow up at outpatient clinics, and adjust the steroids according to the doctor's advice. One must not arbitrarily reduce the dose or stop the medication, as this can easily lead to a relapse of nephrotic syndrome.

Nephrotic syndrome urine output

Patients with nephrotic syndrome vary in the amount of urine they produce. Some patients have normal urine output and may not exhibit obvious symptoms of edema, but others may have reduced urine output, which can even lead to acute renal failure. Nephrotic syndrome emphasizes that the glomerular filtration barrier is damaged, resulting in a large amount of urinary protein, with a 24-hour urinary protein quantitative exceeding 3.5 grams. This situation highlights the decreased ability of the filtration barrier to retain proteins in the blood, meaning the integrity of the filtration barrier is compromised. However, the kidney's ability to excrete water and metabolic waste is not indicated by the term "nephrotic syndrome" itself, thus the patient's urine output can vary.

Does nephrotic syndrome cause itchy skin?

Nephrotic syndrome generally does not cause itchy skin in patients. In patients with nephrotic syndrome, the glomerular filtration barrier is severely damaged, leading to a significant presence of urinary protein and edema, but itchy skin is a rare clinical symptom. If a patient experiences itchy skin, it is recommended to visit the dermatology department of a standard hospital. As such patients may have a disordered immune system, they are prone to various skin issues, such as allergic dermatitis and eczema, which might cause symptoms of itchy skin. However, these are not directly related to nephrotic syndrome.

Is nephrotic syndrome nauseating?

Nephrotic syndrome generally does not cause symptoms of nausea. Nephrotic syndrome refers to the damage to the glomerular capillaries of the patient, with the patient's 24-hour urinary protein quantification exceeding 3.5 grams, which indicates a substantial presence of urinary protein. This disease can cause edema in various parts of the body, such as the lower limbs, eyelids, and facial area. However, it generally does not cause digestive symptoms such as nausea and vomiting. If a patient exhibits such symptoms, it is necessary to be cautious as it may indicate the onset of acute renal failure due to nephrotic syndrome, or the presence of acute inflammation in the gastrointestinal tract. Patients with nephrotic syndrome generally may experience edema in the gastrointestinal tract, which could cause nausea, and it is important to be cautious of the possibility of other underlying causes.

Is nephrotic syndrome contagious?

So, nephrotic syndrome is a general term for a group of clinical symptoms, a state of disease, and is not essentially an independent disease. Thus, this problem is not infectious. This disease describes the damage to the kidneys due to some reason, leading to the disruption of the integrity of the glomerular filtration barrier, resulting in the patient developing a significant amount of urinary protein. The disease itself is not contagious. However, there are very few cases of nephrotic syndrome that might be caused by hepatitis B virus infecting the kidneys. In such cases, the hepatitis B virus may have a certain level of contagiousness, but even so, it does not imply that nephrotic syndrome itself is contagious. In other words, even if such patients transmit hepatitis B to others, it does not necessarily mean those others will exhibit kidney damage.
