Some women feel as they're salivating more than usual during pregnancy, especially when they're nauseated. A few have so much saliva they end up spitting. Excessive salivation is common among women suffering from hyperemesis gravidarum (a severe form of morning sickness).
Cause is still unknown but hormonal changes during pregnancy are associated with it. Also, nausea might make women try to swallow less, causing excessive salivation. It can also be related to heartburn, which is common during pregnancy.
The gastric contents are acidic, and when they regurgitate, they irritate your esophagus and cause the burning sensation like heartburn sufferers. The acid triggers your salivary glands to produce saliva that has an increased concentration of bicarbonate, which is alkaline, to counteract the acid. Every time you swallow, your saliva washes the walls of your esophagus and helps neutralize the gastric acid. This may explain why women who are vomiting tend to salivate more. Certain medications and smoking can also precipitate this problem.
Tips to minimize your discomfort:
1. Let your caregiver know the problem so she can help you try to relieve any underlying problems, such as nausea, vomiting, or heartburn.
2. Quit smoking (if you’re a smoker)
3. Brush your teeth and use mouthwash several times a day may be helpful
4. Eat frequent, small, balanced meals, and avoid too much amount of starchy foods.
5. Drink plenty of water. Keep a water bottle handy and take frequent small sips.
6. Suck on hard candy or chew sugarless gum. It will make it easier for you to swallow the saliva you do produce frequently.
Good luck to you and best wishes!
