Frequent regurgitation of food in elderly people with uremia should be considered to be related to the accumulation of toxins in the body, but it may also be caused by water retention. In addition, we should not ignore the possibility of gastrointestinal disease. The toxins in the body of uremic patients are slowly accumulated, when the toxins are accumulated to the gastrointestinal tract, it is easy for the patient to experience nausea, vomiting and other uncomfortable symptoms. In addition, water retention also tends to cause patients to experience frequent regurgitation and nausea. Because the kidney function of uremia patients is difficult to play a major role, so the drainage function of the kidneys will be weakened, and then water retention will occur. Water retention will cause edema of internal organs, especially the gastrointestinal tract, so the patient will have nausea and regurgitation symptoms, especially in the morning is more obvious. In addition, frequent regurgitation cannot be excluded from the possibility of gastrointestinal diseases, and it is recommended that gastroenteroscopy and CT examination of the whole abdomen be performed to assist in the diagnosis and treatment and assessment of the condition if necessary. Uremic patients are advised to go to the regular hospital in time, under the guidance of the physician standardized treatment.
