About this symptom

Dry Mouth/Increased Thirst

Dry mouth during early pregnancy is very common, and quite normal. As the body is gearing up for pregnancy, including increasing blood volume by half, lots of fluids are required, and if they are not replenished dry mouth is inevitable. Keep a water bottle handy at all times and keep hydrated. If dry mouth is excessive or includes insatiable thirst, cracked/peeling lips, or bad breath, that could be a sign of gestational diabetes and should be reported to your health care provider.
