Excessive salivation during pregnancy is common, especially at the early stages. You may salivate more and, at times, even drool when pregnant. Hypersalivation is also known by other medical terms such as ptyalism gravidarum and sialorrhea (1).

The condition may occur along with nausea and vomiting. Read this post as we tell you whether or not it is normal for pregnant women to salivate more and how to manage the condition with or without medications.

Increased Salivation In Pregnancy: Is It Common?

Excess salivation is common during the first stage of pregnancy, although it reduces as the months pass by. However, if you have nausea, it may continue in the second trimester as well, and sometimes lasts until the delivery.

An average person produces around 60 ounces of saliva in a day (2). When pregnant, this amount goes up. You may notice the change if you are salivating more than usual or have difficulty swallowing the saliva because of nausea or vomiting. Either way, it is normal.

When In Pregnancy Does Hypersalivation Usually Start?

Increased saliva production begins in the first trimester of pregnancy, usually in the second or third week (1). For some women, it reduces by the beginning of the second trimester. But for others, the condition persists throughout their pregnancy and disappears after delivery.

The origin or exact cause of excessive salivation during pregnancy is unknown, although it is most likely due to the hormonal changes. In any case, there is absolutely no need to worry about this condition.

Causes Of Hypersalivation In Pregnancy

Some of the causes that might lead to excessive saliva during pregnancy are:

  • Nausea: This is a common symptom that you will experience in the first few weeks of pregnancy. Nausea may prevent you from swallowing, leading to an excessive build-up of the saliva. Morning sickness that is severe and lasting longer than usual is called hyperemesis gravidarum (3) (4).
  • Medications: One of the side effects of certain medicines is the excessive production of saliva. Anticonvulsants, tranquilizers, and anticholinergic medicines intervene with the functioning of the salivary glands and block parasympathetic innervation, resulting in more saliva production (5).
  • Heartburn: Acid reflux or heartburn is a condition when the valve between the stomach and the esophagus opens, allowing the stomach acid to move into the esophagus. When it occurs during pregnancy, women experience throat irritation or a burning sensation in the chest. The acid activates the salivary glands, which increases the production of saliva (6). Even if you have certain allergies, you may experience ptyalism (7).
  • Hormonal changes: Excessive saliva is produced more during early pregnancy and the third trimester. Doctors say it could be due to hormonal changes, but there is no proper scientific evidence to prove it.
  • Oral infection: Optimal oral health is essential for pregnant women. But healthy pregnant women can also have oral cavity problems that might increase the risks of oral infection. This may lead to ptyalism, too (8).
  • Irritants or chemicals: Exposure to certain toxins and chemicals could be responsible for ptyalism during pregnancy. Also, certain medications for oral infections or any vulnerability to pesticides could result in increased salivation. This usually occurs when mercury is present in the medications/substances you are exposed to (9).
  • Maternal anxiety: Pregnancy is a time when women experience physical discomfort and mental anxiety. They tend to swallow less saliva when they are anxious, and this feels like excess saliva is being produced (10).

Irrespective of what is causing excessive saliva in pregnancy, you shouldn’t be worried, for it is a common symptom and will subside eventually. Increased salivation could even be good for you sometimes.

Are There Any Benefits Of Excess Saliva?

Yes, hypersalivation helps manage a few concerns that are common during pregnancy.

  1. Helps in digestion: Indigestion is pretty common in pregnancy. Increased salivation aids in digestion by helping to break down starch into maltose and then into glucose (11).
  1. Neutralizes acids: Saliva contains phosphorus and calcium and is considered a relative of blood. It neutralizes the acids and maintains gastroesophageal reflux, and eventually soothes heartburn, which is a common symptom of pregnancy (6).
  1. Lubricates mouth: Dry mouth is one of the common symptoms during early pregnancy (12). The production of mucus with increased salivation lubricates the mouth and prevents food from sticking to the gums and teeth (13).
  1. Oral hygiene: Nausea and vomiting during pregnancy are likely to increase the risks of oral infections. However, excessive saliva moistens the mouth, keeps away germs and bad breath, and prevents gum diseases and tooth decay (14).
  1. Natural defense against bacteria: Oral infections and bacteria may form plaque in the mouth (15). The salivary glands collect nitrate (from blood) and help in fighting bacteria, hence acting as a natural defense against agents that could harm gums and teeth.

Although excessive salivation is good, it becomes irritating when accompanied by nausea and morning sickness. There are, however, ways to treat it.

How Do You Get Rid Of Excess Saliva During Pregnancy?

There are several remedies you can try to get relief from hypersalivation.

  1. Always keep a bottle of water at your side and stay hydrated at all times
  1. Brush your teeth twice a day. Also, rinse using a mouthwash as many times as you can during the day, to get rid of the excess saliva.
  1. Reduce the amount of starchy food in your diet and eat well-balanced meals. Try to have small meals at regular intervals throughout the day. Also, you can add fibrous vegetables and fruits to your diet.
  1. Suck on sugarless chewing gum or candy to swallow the extra saliva. While this won’t bring down the production of saliva, it will make swallowing a lot easier. Sucking on ice cubes is another trick that makes your mouth numb for a while and pauses the secretion of saliva.
  1. Munch on dry biscuits, it can help soak the extra saliva in your mouth.
  1. If you have difficulty swallowing the excessive saliva, spit out in a cup, tissue, or washcloth, and then throw it.
  1. Treating ptyalism with drugs is considered challenging, as the exact cause is not known. Medications such as belladonna and phenothiazine can be taken, although they have certain side-effects such as constipation and dry mouth (16).

Frequently Asked Questions

1. Can I prevent excessive saliva in pregnancy?

No, increased secretion of saliva is a natural, short-term condition in pregnancy and cannot be prevented. There is no need to worry about it since it doesn’t affect your baby in any way (17). Keep calm, use natural remedies that offer relief, and try distracting yourself.

2. When does the production of excess saliva end?

Just like the other symptoms of pregnancy, increased salivation is unpleasant and disturbing but tends to go away after the first trimester. However, for some women, it may continue into the second and third trimester as well, fading completely after the delivery.

3. Is it necessary to visit the doctor?

If the condition is not creating any problems other than causing a little discomfort, then you do not have to visit the doctor. However, if it is becoming intense and resulting in excessive vomiting, you should consult your doctor to know how to manage the condition better and look for other contributing causes.

Excessive saliva during pregnancy is common, and it is mostly caused by nausea and vomiting, especially in the early stages. Therefore, there is no need to be concerned about this condition. In fact, it may even help address other common pregnancy issues such as indigestion, heartburn, and mouth infections. However, if it irritates you and interferes with your daily life, you could try some helpful salivation prevention and reduction measures. For example, staying hydrated, brushing your teeth, using mouthwash, and avoiding starchy meals might be beneficial.
