Why dialysis can cause low blood sugar

Why dialysis is associated with low blood sugar? Episodes of hypoglycemia is a potentially important risk factor of ischemic heart disease patients. Compared with normal blood sugar and high blood sugar, hypoglycemia and cardiac ischemia more relevant, it can cause an increase in left ventricular systolic function, heart rate, so that the increased cardiac output, blood pressure, blood was combined with high viscosity state and eventually can cause or aggravate angina and myocardial infarction, and even cause sudden death. HD patients with diabetic nephropathy after dialysis glycemic control is more difficult than before, then why dialysis is associated with low blood sugar do? Listen to introduce a kidney specialist at the bar.

In the dialysis process some factors that promote the occurrence of hypoglycemia.

The most commonly used are sugar-free dialysate bicarbonate dialysate, because it has to reduce bacterial growth, preventing hyperlipidemia advantages are widely used. However, studies have found that, when using the sugar-free dialysate hemodialysis, affected by the concentration gradient of glucose in the blood by a dialysis membrane into the dialysis fluid, one treatment (4h) loss of glucose 25 ~ 30g, resulting in low blood sugar occur.

In addition, patients on dialysis between excessive intake of water and salt cause weight gain, such as dialysis, ultrafiltration lot of moisture, which can cause reduced blood pressure, which affects diet, and promote the occurrence of hypoglycemia. If the patient is inadequate dialysis, dialysate water quality without reverse osmosis treatment also can cause patients with poor appetite, vomiting, also easily lead to hypoglycemia.

For uremic patients, since urea, methyl guanidine and polyamine uremic toxins, acidosis and anemia and other factors, so that patients with poor appetite, nausea, vomiting or diarrhea, leading to the absorption of glucose reduction, likely to cause low blood sugar It occurred.

Why dialysis is associated with hypoglycemia? Concurrent dialysis hypoglycemia reasons we all know, so we must learn some knowledge of prevention and treatment of hypoglycemia, actively carry out prevention and treatment of hypoglycemia.
