About this symptom

Increased Saliva

Excessive salivation (also known as ptyalism) can occur in early pregnancy, although the reason for it is not fully known. Some experts believe hormonal changes occurring in the body could be one cause. Women who are suffering from nausea also tend to swallow less which may cause a build of up saliva in the mouth. Whether it is due to an increased production of saliva or a build up caused by decreased swallowing, ptyalism will generally subside after 12 to 14 weeks, although in some cases it can continue or return throughout pregnancy.
