Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder and is characterized by recurrent episodes of complete or partial obstruction of the upper airway leading to reduced or absent breathing during sleep. These episodes are termed " apneas " with complete or near-complete cessation of breathing, or " hypopneas " when ...
Treatment-emergent central sleep apnea (TECSA), also known as complex sleep apnea, is a type of sleep apnea that typically develops when a patient starts CPAP therapy for OSA. This can occur when ...
Endocrinology. Hypertryptophanemia is a rare autosomal recessive [2] metabolic disorder that results in a massive buildup of the amino acid tryptophan in the blood, with associated symptoms and tryptophanuria (-uria denotes 'in the urine '). [3][4] Elevated levels of tryptophan are also seen in Hartnup disease, [5] a disorder of amino acid ...
Obesity. Obesity hypoventilation syndrome (OHS) is a condition in which severely overweight people fail to breathe rapidly or deeply enough, resulting in low oxygen levels and high blood carbon dioxide (CO 2) levels. The syndrome is often associated with obstructive sleep apnea (OSA), which causes periods of absent or reduced breathing in sleep ...
The conditions of hypoxia and hypercapnia, whether caused by apnea or not, trigger additional effects on the body.The immediate effects of central sleep apnea on the body depend on how long the failure to breathe endures, how short is the interval between failures to breathe, and the presence or absence of independent conditions whose effects amplify those of an apneic episode.
Frequency. ~ 1 in every 10 people, [3][9] 2:1 ratio of men to women, aging and obesity higher risk [5] Sleep apnea, British English sleep apnoea or sleep apnœa, is a sleep-related breathing disorder in which repetitive pauses in breathing, periods of shallow breathing, or collapse of the upper airway during sleep results in poor ventilation ...
Sleep and weight is the association between the amount of sleep an individual obtains and the weight of that individual. Numerous studies have demonstrated an association between sleep disturbances and weight gain, and more specifically, that sleep deprivation is related to overweight. [1] Furthermore, body weight also influences the quality of ...
Symptoms. groaning or moaning during sleep. Catathrenia or nocturnal groaning is a sleep-related breathing disorder, consisting of end-inspiratory apnea (breath holding) and expiratory groaning during sleep. It describes a rare condition characterized by monotonous, irregular groans while sleeping. [1] Catathrenia begins with a deep inspiration.
