Vomiting and nausea in diabetic dialysis patients may be caused by the adverse reaction of dialysis, or considered to be caused by anemia, electrolyte disorders and other complications, which need to be treated accordingly. 1. Adverse reaction of dialysis: due to excessive and rapid dehydration in the process of dialysis, it may lead to the decrease of blood volume of the patient, and vomiting and nausea may occur. If this kind of situation occurs, generally there is no need for special treatment, adjusting the speed of dialysis can be relieved. 2. Anemia: Vomiting and nausea in diabetic dialysis patients may be caused by anemia. Patients need to take oral iron supplements, such as ferrous gluconate, iron sorbitol, etc., under the guidance of doctors, so as to improve the discomfort symptoms. 3. Electrolyte disorders: Vomiting and nausea in diabetic dialysis patients are also considered to be caused by electrolyte disorders. Electrolyte disorders can be corrected in time, and for patients with frequent vomiting and nausea, some drugs can be applied to reduce gastrointestinal reactions, such as metoclopramide, etc. to relieve the symptoms of vomiting. There are many reasons for diabetic dialysis patients to experience vomiting and nausea, and it is recommended that patients identify the causes of the disease in a timely manner and treat the symptoms under the guidance of the doctor.
