Excessive dehydration on dialysis may lead to symptoms such as dialysis imbalance syndrome, low blood pressure, low blood sugar, etc. It is recommended to seek medical treatment in time. 1. Dialysis Imbalance Syndrome: Due to the rapid decrease of toxins in the blood after dialysis, but the decrease of toxins in the brain is not very obvious, which leads to the osmotic pressure in the brain is too high and cerebral edema occurs gradually, which can be manifested as nausea, vomiting, dizziness, headache and other symptoms. 2. Decreased blood pressure: too much dehydration may cause the blood volume to drop, resulting in low blood pressure, and when the body is in an ischemic state, especially muscle ischemia may also cause spasms and pain. 3. Hypoglycemia: Since there is no sugar on the dialysis side of the dialysis solution, the sugar in the blood will penetrate into this side of the dialysis solution, which will gradually lower the blood sugar, thus causing hypoglycemic reactions, such as sweating, trembling, panic and other symptoms. If the above symptoms occur, it is recommended to go to regular hospitals in time to find out the cause and follow the doctor’s instructions for standardized treatment.
