What are the risks of untreated sleep apnea?

Accueil > Elderly Health Care > Sleep Apnea

Untreated sleep apnea can have a significant impact on an individual's health and quality of life. It is a serious medical condition that can lead to a range of both short-term and long-term risks and consequences.

Here are some of the potential risks of untreated sleep apnea:


  • Excessive Daytime Sleepiness: Sleep apnea disrupts the normal sleep cycle, leading to frequent awakenings throughout the night. This results in persistent daytime sleepiness, which can impair cognitive function, concentration, and the ability to perform daily tasks safely.

  • Cardiovascular Problems: Sleep apnea is associated with an increased risk of cardiovascular conditions, including:

    • Hypertension (High Blood Pressure): Sleep apnea can cause abrupt blood pressure spikes during apnea episodes, contributing to the development or worsening of hypertension.

    • Heart Disease: Individuals with untreated sleep apnea are at a higher risk of developing heart disease, including coronary artery disease, irregular heart rhythms (arrhythmias), and heart failure.

    • Stroke: Sleep apnea is a significant risk factor for ischemic strokes, which occur when there is a blockage in a blood vessel supplying the brain.

    • Atrial Fibrillation: Sleep apnea has been linked to the development and progression of atrial fibrillation, a type of irregular heartbeat that can increase the risk of stroke and other cardiovascular problems.

  • Metabolic Disorders: Untreated sleep apnea is associated with metabolic disturbances, such as insulin resistance and glucose intolerance, which can lead to an increased risk of type 2 diabetes.

  • Weight Gain: Sleep apnea and obesity often go hand in hand. Excessive daytime sleepiness can lead to decreased physical activity, and hormonal imbalances associated with sleep apnea may contribute to weight gain.

  • Cognitive Impairment: Chronic sleep deprivation from untreated sleep apnea can lead to cognitive impairment, memory problems, difficulties with decision-making, and a decline in overall cognitive function.

  • Mood Disorders: Sleep apnea is linked to mood disorders such as depression and anxiety. Sleep disturbances and oxygen deprivation during apnea episodes can contribute to these conditions.

  • Increased Accident Risk: Individuals with untreated sleep apnea are at a higher risk of accidents, including motor vehicle accidents, due to impaired alertness and daytime sleepiness.

  • Decreased Quality of Life: Untreated sleep apnea can lead to a reduced quality of life due to persistent fatigue, diminished cognitive abilities, and the strain it places on relationships.

  • Worsening of Preexisting Conditions: Sleep apnea can worsen preexisting medical conditions, such as asthma or chronic obstructive pulmonary disease (COPD).

  • Complications during Surgery: Sleep apnea increases the risk of complications during surgery and anesthesia, making it essential to identify and manage the condition before surgical procedures.

It's crucial to recognize that effective treatment for sleep apnea can significantly reduce these risks and improve overall health and well-being.
