Snoring is common in adults and usually is indicative of an increase in the resistance of the upper airway and may be a sign of obstructive sleep apnea, obstructive sleep apnea. Snoring may also be associated with morphological conditions that narrow the upper airway, such as obesity, nasal congestion, craniofacial abnormalities, hypothyroidism, acromegaly, and adenotonsillar hypertrophy.
The pathogenic mechanisms of snoring are complex. It is a respiratory noise acoustically, is due to the vibration of the wall of the oropharynx, where the permeability of the upper airway is altered by some of the many factors that regulate. These factors predisposing to pharyngeal light reduction are at the root of snoring by the pharyngeal collapsibility oropharynx level.
• Importance of nasal breathing. Mouth breathing is a common condition that predisposes to snoring. When bilateral nasal obstruction is the increased resistance causes an arousal that restores the flow through the mouth breathing resistance increases by the reduction in pharyngeal caliber caused by rearward suprahyoid structures. Snoring may also be related to a deviated nasal septum, an enlarged turbinates of the nose, tonsils or palate, chronic laryngitis, tenderness in the muscles of the mouth or throat or nasal obstruction passing. Any of these factors predispose to pharyngeal light reduction, decreasing the advent of air conditioning lungs sound vibration that causes snoring.
• Obesity is the most important factor in sleepdisordered breathing. Overweight directly affects the size of the VAS, possibly by the accumulation of fat peripharyngeal decreasing section of the airway and the metabolic and endocrine morbidity associated with obese patients.
• Postural factors. The supine position increases the likelihood of snoring by the displacement of the jaw structures 13 points further behind
• The intake of alcohol and sedatives, promote snoring and OSA, its depressant action on the respiratory center.
• The snuff acts by increasing the intensity of snoring to be due to inflammation and edema, and secondarily, causes pharyngeal narrowing.
• Sex. There is a greater prevalence of snoring in men than women. The reason for this difference is not yet known, but shuffled the possible influence of sex hormones and anthropometric factors, although at present there is no conclusive study. What if it is proven is that the progesterone hormone (typically female), provide ventilation and snoring improved with pharmacological administration of progesterone. The female is hormonally protected from snoring, but that may change with the arrival of a pregnancy due to increased segregation of a hormone, progesterone, which results in an increase in nasal congestion.
• Age. The increased prevalence of snoring with age has been demonstrated in all epidemiological studies. About 20% of adults in middle age of life are snorers, this percentage varies in response to population studies by age subgroups, 10% men and 5% women aged 30 years and 60% male and 40% female from 60. The age factor is instrumental in the development of snoring.
In children, the prevalence is quite high, but lower than in adults, but with a most alarming condition, and that snoring can cause behavioral problems and cognitive failures. In the XXI Congress of the Spanish Society of Pediatrics Outpatient and Primary Care, Jordi Coromina said 12% of children are snoring and half of them have urinary incontinence when they sleep. In addition, these sleep apnea are three times the risk of a disorder attention deficit hyperactivity disorder and studies suggest that children who snore can lose up to 11 points from their IQ and do so affected their school performance by fatigue and disorders of behavior that are suffering.
In the same vein, according to a report of the Central Hospital of the University of Helsinki, published in the Journal of Developmental and Behavioral Pediatrics, children who snore are more likely to have other sleep problems such as nightmares, somniloquy, or difficulty going to the bed and have more symptoms of depression and anxiety as well as language and attention problems than their peers without snoring.
