Sleep apnea not only affects the quality of your rest but also has serious implications for your overall health. It is characterized by repeated stopping and starting of breathing during sleep. Effects on the Cardiovascular System: The disorder can cause sudden drops in blood oxygen levels, which in turn increases blood pressure and strains the cardiovascular system. This can lead to heart disease, recurrent heart attacks, irregular heartbeat, and potentially stroke or other heart-related complications. Metabolic Effects: Sleep apnea is also linked with metabolic issues such as insulin resistance and type 2 diabetes. The disruption in your body's normal sleep-wake cycle can lead to weight gain and obesity, further exacerbating these problems. Sleep-Related Problems: One of the most noticeable impacts of sleep apnea is excessive daytime fatigue due to a lack of good night's sleep. Other Effects: Other health conditions, including respiratory problems, can also be exacerbated by sleep apnea. For instance, those with the condition might experience difficulty breathing during the day and it can worsen asthma and chronic obstructive pulmonary disease (COPD). Sleep apnea has also been linked to other health issues like headaches, mood disorders, gastrointestinal problems, and erectile dysfunction in men.
