Overlap syndrome is a general term used to describe when a person has a number of medical situations that, together, create a unique set of signs or change the course of each disease. One potential type of overlap syndrome includes an individual having each obstructive sleep apnea (OSA) and chronic obstructive pulmonary illness (COPD). Obstructive sleep apnea is the most typical form of sleep apnea and causes temporary reductions or pauses in breathing during sleep. COPD is a chronic lung condition that advances over time and interferes with breathing within the daytime and through sleep. How Are COPD and Sleep Apnea Linked? COPD and OSA are both widespread breathing-associated medical circumstances. COPD impacts greater than 6% of individuals in the United States, while obstructive sleep apnea happens in around 10% to 30%. While estimates vary, studies recommend that round 1% of people have overlap syndrome, that means they've been diagnosed with each COPD and OSA. These situations share a number of danger components.



Factors that enhance the probabilities of growing each COPD and OSA embrace smoking, the usage of opioids, BloodVitals heart-associated circumstances, and obesity. Despite these similarities, specialists are uncertain if COPD and sleep apnea are actually an overlap syndrome, that means that together they cause new symptoms or results, or if the 2 conditions are steadily diagnosed together because both are widespread. Can COPD Cause Sleep Apnea? Although several theories exist about potential relationships between COPD and sleep apnea, it is unknown whether or not COPD causes or contributes to the event of obstructive sleep apnea. While some research have proven an elevated danger of OSA in individuals with COPD, other research have not discovered this connection. Studies have discovered that overlap syndrome impacts sleep quality, COPD signs, the risk of different well being points, and a person’s overall quality of life. Sleep quality: Both COPD and OSA are associated with sleep issues. However, people with overlap syndrome are likely to have extra nighttime awakenings and worse sleep quality than these with either COPD or OSA on their own.



COPD signs: Research suggests that overlap syndrome causes more frequent flare-ups of COPD. During a COPD flare-up, an individual may cough extra, spit up mucus, and have problem respiration. Health issues: Overlap syndrome is linked to an elevated threat of doubtlessly extreme cardiovascular diseases, including heart failure, high blood strain, and irregular heart rhythms. Together these conditions may have an effect on a person’s life expectancy. Lots of the risks related to overlap syndrome stem from the decrease blood oxygen ranges folks with COPD and OSA experience during sleep. Lower blood oxygen ranges happen with these disorders for a couple of causes. COPD makes it harder to breathe and impacts the lungs’ potential to alternate carbon dioxide for oxygen. These modifications reduce the quantity of oxygen in the blood, an effect that can be exacerbated by pure changes in breathing that occur after falling asleep. OSA also interferes with the body’s potential to get sufficient oxygen throughout sleep. When the airway becomes blocked because of OSA and the sleeper’s breathing is briefly restricted or stopped, the level of oxygen in the blood decreases.



While both COPD and OSA can contribute to low oxygen ranges, overlap syndrome is related to more severe lack of oxygen than either situation by itself. Researchers imagine that that is the first reason why overlap syndrome could enhance a person's danger of growing other health issues, like coronary heart disease. The best way that docs test for overlap syndrome depends on an individual’s medical history and symptoms. Experts consider an in a single day sleep research the optimum test for diagnosing overlap syndrome in people with COPD. Doctors may advocate that a person use an at-residence pulse oximeter to measure blood oxygen ranges overnight. Doctors might also recommend testing for overlap syndrome in folks with OSA who're discovered to have abnormal levels of oxygen or carbon dioxide during the daytime. Testing for overlap syndrome is vital as a result of it permits medical doctors to suggest applicable treatment and conduct additional testing to detect potential complications of the situation.



Often, treating overlap syndrome includes treating OSA and COPD individually. To handle both situations at the identical time, docs will consider an individual’s distinctive needs and the severity of each situation. Treatment targets are to enhance sleep, normalize nighttime oxygen ranges, and reduce the health penalties of both situations. Treatments that handle OSA symptoms include conduct adjustments, like avoiding alcohol consumption, and constructive airway pressure (PAP) therapy. COPD therapies might involve medication, advice to stop smoking, and oxygen therapy. PAP therapy is the cornerstone of treatment for people with overlap syndrome. By helping keep the airway open during sleep using pressurized air, PAP therapy has been shown to enhance a person’s life expectancy, minimize nighttime respiration disruptions, cut back COPD flare-ups, BloodVitals and assist individuals better tolerate train throughout the day. Doctors sometimes begin people with overlap syndrome on a continuous constructive airway strain (CPAP) machine. Other types of PAP devices could also be beneficial for people who require a high level of air strain during sleep.
