Can pregnancy cause dry mouth?

Pregnant women’s metabolism is high during pregnancy and their need for water increases, so feeling thirsty may be a sign that the foetus needs more water, but it may also indicate the onset of illness.
Some pregnant women may develop gestational diabetes due to increased glucose requirements and increased insulin resistance, and those who are overweight or obese before pregnancy, who gain too much weight during pregnancy and who have a family history of diabetes are more likely to develop the disease. Therefore, if you experience dry mouth during pregnancy, you should be alerted to the possibility of gestational diabetes, and a hospital visit is recommended for a clear diagnosis of fasting blood sugar, glucose tolerance test and glycated haemoglobin.
Dry mouth is also evident in gestational diabetes mellitus. It is often characterised by extreme thirst, accompanied by polyuria, irritability, heavy drinking, low specific gravity urine and hypotonic urine, occurring in late pregnancy and a short time after delivery, with urine output of up to 5-10 litres per day, and mostly resolving a few weeks after delivery. Gestational enuresis is easily diagnosed and managed, but care must be taken to avoid severe hypernatraemia.
