Profuse salivation in adults may be a sign of cerebral circulatory disorders, inflammation of the trigeminal nerve if helminthiasis. For children up to one year increased salivation
Increased salivation - deviation from the norm
is often only apparent - the child has not yet learned to swallow saliva. Salivation increases with the child's teething

Why saliva
Saliva - the secret is a mixed salivary (parotid, submandibular, sublingual, minor salivary) glands, eye-catching in the mouth and is involved in digestion. This hazy viscous liquid, which includes water and dissolved organic and mineral substances. Organic substances are salivary proteins that are synthesized in the salivary glands, and outside, including immunoglobulins that act as antibodies.
Saliva also has monosaccharides, cholesterol, fatty acids, hormones (sex, glucocorticoid), vitamins C and group B present in the saliva of the enzymes involved in the digestion of starch. Rich saliva and minerals: potassium, calcium, magnesium, iron, copper, chlorine, fluorine, iodine, and so on. It contains mucins form and glued bolus and bactericide lysozyme inactivates pathogens.
Innervated by the salivary glands are mainly parasympathetic (PNS) nerve fibers, but the sympathetic (SNS) system is also partially participated in the process. With the predominance PNS occurs a large amount of saliva with low protein content. If the predominant effect SNA stands little saliva, but it has a high viscosity. Regulation salivation carried nerve centers in the cerebral cortex, hypothalamus, and medulla oblongata. Normally, in a healthy person is allocated to two liters of saliva per day.
The main functions of saliva:
- wetting of the oral cavity and thus ensuring the normal articulation;
- support the perception of taste sensations;
- forming and bonding bolus;
- wetting of the oropharynx and maintenance of swallowing;
- cleansing of the oral cavity from infectious agents. Their metabolic products and decomposition products of tissue;
- the provision of primary stage of digestion of carbohydrates.
Causes of excessive salivation in humans
In some diseases and conditions of saliva flow can be increased by several times. This is called hypersalivation or ptyalism. Profuse salivation in adults may occur in patients suffering from Parkinson's disease, epidemic encephalitis, stroke, various diseases of the hypothalamus.
In addition, hypersalivation can be a reflex that occurs as a protective reaction of the body in response to a variety of diseases of the oral cavity: stomatitis, gingivitis, tonsillitis

and so on. Increased salivation may also be neuralgia

trigeminal nerve.
Salivating at the child
In children aged 3-6 months, increased salivation is a physiological nature: salivary glands begin to function and the child does not have time to swallow a large amount of saliva. Later salivating in infants and is often associated with this cause, therefore, it is relative. Most children (and sometimes adults) can be salivating at night. The reason is that during the night the action of the parasympathetic nervous system dominates the action of the sympathetic.
Salivation is amplified with the appearance of inflammation of the mouth, which is a physiological response, promoting leaching of pathogens, toxins and their decay products tissues.
Excessive salivation during pregnancy
Hypersalivation often is one of the manifestations of early toxicity pregnant. By the second trimester, all the manifestations of toxicity are usually held. Currently, the causes of early toxicity have not been established definitively. Nevertheless, we can assume that they are partly related to the reorganization of neurohumoral organism of a pregnant woman. For example, excessive salivation may be related to effects on the prevalence of the parasympathetic nervous system women. Activation of the PNS may also cause drowsiness and lethargy, developing in women in the first weeks of pregnancy.
At the expressed hypersalivation woman can lose up to several liters of saliva per day, which leads to dehydration. Such women are hospitalized and intravenously injected with saline.
After an early morning sickness is over, small hypersalivation may occur with heartburn, which often disturbs pregnant.
Excessive salivation can cause serious illness, so with this symptom should seek medical advice.
