The dry throat of dialysis patients may be related to the drugs taken by the patients, the reduction of fluid intake of the patients, and the elevation of salivary viscosity by dialysis. 1. Drug factors: because dialysis patients may have various basic diseases such as hypertension, high blood pressure patients who take drugs such as Prilosec are likely to inhibit the secretion of the glands, thus causing dry throat, generally in the discontinuation of the drug or replacement of other medication, the situation will be improved. 2. Decreased fluid intake: Because dialysis patients need to stay in the dialysis room for a long time and have to control their intake, these can also lead to dry throat. In addition, some dialysis patients may develop complications such as salivary gland atrophy, which may also cause the above situation. 3. Increased salivary viscosity: dialysis will make the patient’s salivary viscosity increase, to a certain extent, will also increase the concentration of urea, protein and other components, resulting in the above situation. When dialysis patients have dry throat, it is recommended to clarify the specific causes under the guidance of professional doctors and treat them actively.
