Vomiting in dialysis patients with diabetic nephropathy can be caused by post-dialysis hypoglycemia, which can be supplemented with glucose in time; if it is caused by blood pressure abnormality, it needs to be treated by lowering or raising the blood pressure according to the blood pressure level. 1. Hypoglycemia: diabetic patients’ blood sugar level is unstable, if hypoglycemia occurs after dialysis, it can cause vomiting, at this time, glucose can be supplemented to raise blood sugar. 2. Abnormal blood pressure: During the dialysis process, the patient’s blood pressure is abnormal, such as hypertension, hypotension, etc., which can cause nausea and vomiting, at this time, nifedipine can be used to lower the blood pressure or active supplementation of blood volume to elevate blood pressure treatment. Diabetic nephropathy dialysis patients vomiting, should go to the hospital in time, under the guidance of the doctor to identify the causes of active treatment, so as not to delay the condition.
