Moreover, during a dental job, certain instruments or solutions stimulate the soft palate and aggravate the feeling to gag. Adults may experience it while getting a dental job done, which requires the person to keep his mouth open for a very long time. Basically, anything that brushes against the soft palate and stimulates it, results in a gag. Certain activities that need you to open your mouth for a long time or putting something in the mouth can also result in a gag. It’s just an aversion to certain textures of food that induces a severe urge to gag. There are no particular causes of hyperactive gag reflex as such. Finally, these signals reach the brain which sends back instructions, in the form of electric pulses and chemical signals, back to the pharyngeal nerves to contract and cause such invasive objects to be expelled.
These nerve fibers transmit the gag sensations to the solitary tract and spinal trigeminal nuclei. The glossopharyngeal nerve fibers, which pass from behind the nasal cavity, pick up the sensation whenever an unnaturally large amount of food is swallowed or something other than food is attempted to be pushed down the throat. Whenever something that is not part of the natural swallowing process enters the throat so far as to touch the soft palate, the back of the throat contracts and we get a feeling that we are about to vomit. This method is widely used by bulimics, victims of a kind of eating disorder, who frequently induce vomiting this way soon after eating something. However, sometimes gagging is artificially induced by sticking one’s finger inside the mouth, far down the throat, to orally expel food that was recently eaten. Gagging is a natural phenomenon which is meant to prevent anything, which is not part of the natural eating and swallowing process, from entering the throat in order to keep the person from choking by obstruction of the respiratory tract, the upper part of which is connected to the upper part of the digestive tract. There are different levels of sensitivity among different people with regards to causes and extent of gag reflex. The irritation caused to the pharynx by such an activity always, without fail, evokes a disgusting feeling as if you’re going to throw up. This makes it impossible to feed them.īefore getting to gag reflex causes, let us first get to the mechanism behind this awful feeling of throwing up whenever you stick something in your mouth that goes far towards the back of your throat and touches the soft palate. Children with this disorder simply refuse to take solid foods or foods with a particular texture. If your baby throws up and chokes herself every time you try to feed her with certain foods, it could be due to hyperactive gag reflex.
It is a very common feeding disorder among children. Every one has a gag, but it becomes a problem when an individual finds it difficult to eat certain foods or perform certain activity. Hyperactive gag reflex is the body’s response to the stimulation of soft palate or posterior pharynx. Hyperactive Gag Reflex: Definition, Description, Causes and Risk Factors:
