Causes of Sleep Drooling in Adults
It estimated that between 15 and 20 percent of adults drool when sleeping. Ptyalism or Sialorrhea is the medical term for this disorder, and it is one of those that make people feel embarrassed. It is normal in the first two years of a baby's life, but it is a disorder that requires attention when it happens in adults. Knowing the causes is the starting point when dealing with the condition and below are five common ones.
1. Neurological disorder
Saliva management during sleep is difficult for people suffering from different neurological disorders, and this one of the main reasons that they will drool. It is also harder for them to control their facial muscles, so swallowing saliva during sleep becomes difficult. A paper published in the British Journal of Medicine Practitioners a couple of years ago concluded that individuals with neurological impairments such as cerebral palsy and autism find it almost impossible to prevent drooling when sleeping.
2. Sleeping on the side
Different research findings over the years prove that sleeping on the side may make a person drool. The mouth is likely to open when sleeping on the side due to gravity and when this happens, the saliva accumulation will end up drooling on the pillow. Any saliva buildup on the mouth will always drain down the throat when a person is sleeping on the back, and this reduces the probability of drooling.
3. Excess acidity
According to an article published on the well-known medical website WebMD, acid reflux can cause the salivary glands to become more active than usual and hence produce excess saliva. The acidity causes esophagus stimulation and this, in turn, excites the salivary reflex and hence causing the production of large volumes of saliva. When people are awake they can control the amount of saliva in the mouth but the same is not true during sleep, and so some of it tends to dribble out.
4. Sinus infections
A sinus infection comes with different breathing and swallowing problems, and it might also lead to drooling. A study by the University of Illinois showed that uncontrollable drooling was one of the common symptoms of sinus infection or sinusitis. The condition may also become worse when a person has a nasal passage blockage because this makes them breathe through the mouth which in turn causes the saliva to trickle from the mouth.
5. Dental issues
Some dental problems like teeth and gum infections can make the mouth sore. They might be very painful and also lead to excess production of saliva. The pain makes it hard to swallow the saliva and, as its generation continues to surge, some of it will start dripping from the mouth in the form of drool.
Drooling when sleeping can come as a result of various medical conditions, but the good thing is that there are different remedies and treatments available. The most important element is to understand the underlying cause. Sinus infections, allergies, and tonsillitis treatment can be enough solution for drooling, but in some rare cases, Botox injection and surgery might be necessary.
