Hypersalivation can contribute to drooling if there is an inability to keep the mouth closed or difficulty in swallowing (dysphagia) the excess saliva, which can lead to excessive spitting. Hypersalivation also often precedes emesis (vomiting), where it accompanies nausea (a feeling of needing to vomit).
Excessive salivation, also known as sialorrhea gravidarum, is another symptom experienced by some women. [citation needed] Hyperemesis gravidarum tends to occur in the first trimester of pregnancy [17] and lasts significantly longer than morning sickness.
Drooling can be caused by excess production of saliva, inability to retain saliva within the mouth (incontinence of saliva), or problems with swallowing (dysphagia or odynophagia). There are some frequent and harmless cases of drooling – for instance, a numbed mouth from either benzocaine , or when going to the dentist's office.
In a breakthrough discovery, scientists have identified the cause of pregnancy morning sickness, raising hope for a possible cure. Researchers found that a hormone exposed to pregnant women ...
The exact cause of morning sickness remains unknown. Nausea and vomiting in pregnancy is typically mild and self-limited, resolving on its own by the 14th week of pregnancy. Other causes should also be ruled out when considering treatment. Initial treatment is typically conservative, and may include changes to diet and emotional support.
Pregnant women are expected to fulfill their work obligations up until their delivery. It is normal for pregnant women to experience an increase in salivation and to spit frequently, since they do not believe in swallowing their excess saliva. Women may sometimes carry a spit cup with them and feel no embarrassment in using it in public.
Other causes can be duct stricture (narrowing of the duct), infection or injury. Symptoms may include recurrent swelling, pain and aggravation during eating as this is when saliva production is stimulated. Ductal obstruction may cause less saliva flow, which can result in recurrent gland infections. [8]
