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.
