These are the Main Causes of Obstructive Sleep Apnea

Obstructive apnea may be a common and high disorder during which breathing repeatedly stops for 10 seconds or more during sleep. The disorder leads to decreased oxygen within the blood and may briefly awaken sleepers throughout the night. Apnea has many various possible causes.

In adults, the foremost common explanation for obstructive apnea is excess weight and obesity, which is related to soft tissue of the mouth and throat. During sleep, when tongue muscles and throat are more relaxed, this soft tissue can cause the airway to become blocked. But many other factors are also related to the condition in adults.

In children, causes of obstructive Sleep apnea often include enlarged tonsils or adenoids and dental conditions like an outsized overbite. Less common causes include a tumor or growth within the airway, and birth defects like mongolism and Pierre-Robin syndrome. Mongolism causes enlargement of the tongue, adenoids and tonsils and there’s decreased muscular tonus within the upper airway. Pierre-Robin syndrome actually features a small mandible and therefore the tongue tends to botch and fall to the rear of the throat. Although childhood obesity may cause obstructive apnea, it’s much less commonly related to the condition than adult obesity

Regardless of age, untreated apnea can cause serious problems, including premature death, accidents and Disorder. So it is vital that anyone with signs and symptoms of obstructive apnea — especially loud snoring and repeated nighttime awakenings followed by excessive daytime sleepiness — receive appropriate medical evaluation.

Other Risk Factors for Obstructive apnea

In addition to obesity, other anatomical features related to obstructive apnea — many of them hereditary — include a narrow throat, thick neck, and round head and body pain. Contributing factors may include hypothyroidism, excessive and abnormal growth thanks to excessive production of growth hormone(acromegaly), and allergies and other medical conditions like an abnormality that cause congestion within the upper airways.

In adults, smoking, excessive alcohol use, and/or the utilization of sedatives is usually related to obstructive apnea.

Obstructive apnea and Overweight

More than 50% of people with obstructive apnea are obese or overweight, which is defined as a body mass index (BMI) of 25-29.9 or 30.0 or above, respectively. In adults, excess weight is the strongest risk factor related to obstructive apnea.

Each unit increase in BMI is related to a 14% increased risk of developing apnea , and a tenth weight gain increases the chances of developing moderate or severe obstructive apnea by six fold . Compared to normal-weight adults, those that are obese have a sevenfold increased risk of developing obstructive apnea. But the impact of BMI on obstructive sleep apnea becomes smaller after age 60.
