Thirst Pregnancy

Pregnancy makes you feel thirsty and you may have the sensation of having a dry mouth and throat. Even though you may just have drunk a sip of water, your mouth and throat may still feel dry.

It’s a fine balancing act of drinking enough and not having to pee every 15 minutes! Your bladder is much smaller and sensitive, yet you have such a dry mouth and need to drink.

The sensation of having a dry mouth and throat is medically termed as Xerostomia. This medical condition can also lead to problems with oral hygiene – see Gums.

Why does it happen?
  • Xerostomia is when the body does not produce enough saliva. It is caused by increased blood volume and hormonal changes. Oral hygiene could be impacted; due to a reduced amount of saliva, the bacteria in the mouth is not removed as effectively, leading to build up of plaque or even problems with inflamed gums.
  • Due to the increase in blood volume during pregnancy (up to 40-50%), the body needs more fluids to flush out the extra waste produced by the extra blood. Which means a pregnant woman needs to increase her fluid intake.


    • Suck sweets or mints to keep your mouth moist – aim to buy sugar free and make sure that you brush your teeth at least twice daily.
    • Drink little and often – perhaps you could prepare a can of tee or a Thermos flask to keep yourself regularly topped up with flavoured hot water – like ginger, lemon or mint.
    • Invest in a humidifier for your house – this will also be a huge benefit for your skin health. You will need to look after your skin well, stop it from drying out in order to help to prevent stretch marks.
    • Always consult your doctor if you are experiencing dry mouth symptoms as it could be a sign of diabetes.
