Diabetes mellitus vomiting after dialysis well, half a month and then began to vomit frequently consider the dialysis imbalance syndrome caused by dialysis, electrolyte disorders, the progress of the disease, hypotension, dialysis is not sufficient and so on. 1. Dialysis imbalance syndrome: the rapid removal of solutes during hemodialysis leads to a decrease in the concentration of solutes in the patient’s blood, a decrease in plasma osmolality, and an increase in the difference in osmolality between the brain tissue fluid and the blood, so that the water begins to move to the brain tissue, resulting in an increase in intracranial pressure that leads to the occurrence of vomiting. 2. Electrolyte disorders: patients in the process of dialysis will appear sodium, calcium, potassium and other electrolyte disorders, leading to gastrointestinal dysfunction, and eventually nausea, vomiting symptoms. 3. Disease progression: Diabetic patients on dialysis may also cause frequent vomiting symptoms if their kidney disease further progresses and worsens. 4. Hypotension: During the dialysis process, factors such as too fast dehydration and high amount of water loss may cause hypotension and lead to frequent vomiting. 5. Inadequate dialysis: when dialysis is inadequate, the toxins in the body are not effectively discharged from the body, and uremia is not effectively controlled, which may cause frequent vomiting. It is recommended to go to the hospital and ask the doctor to make a judgment if the diabetic patient starts to vomit frequently again in half a month after the diabetic patient has recovered from vomiting on dialysis.
