# Sleep Apnea: A Heart Risk Alert for Women Over 45
Women over 45 should pay close attention to their sleep patterns. Research now shows that sleep apnea ranks as the top predictor of heart disease in this age group, surpassing traditional risk factors like high blood pressure and high cholesterol.
Sleep apnea occurs when a person's airway becomes blocked repeatedly during sleep, causing breathing to stop and start throughout the night. The condition disrupts oxygen flow to the brain and heart, putting strain on the cardiovascular system night after night.
The connection between sleep apnea and heart disease operates through several mechanisms. When breathing stops, blood oxygen levels drop. The body responds by raising blood pressure and heart rate to compensate. Over time, this repeated stress damages blood vessel walls and increases inflammation, both core drivers of heart disease. Sleep apnea also triggers irregular heartbeat and forces the heart to work harder than it should during sleep.
Women often miss a diagnosis because they attribute sleep apnea symptoms to aging or stress. Common warning signs include loud snoring, gasping for air during sleep, daytime fatigue, difficulty concentrating, and morning headaches. Partners frequently notice the breathing interruptions before women recognize the problem themselves.
The research matters because women have historically been underdiagnosed with sleep apnea. Medical professionals sometimes dismiss women's symptoms or attribute them to anxiety instead of investigating the airway obstruction. This diagnostic gap leaves women vulnerable to undetected heart disease development.
If you experience persistent fatigue despite adequate sleep time, or if your partner reports that you snore or stop breathing during sleep, talk with your doctor about a sleep study. These tests measure oxygen levels and breathing patterns throughout the night. Treatment options range from lifestyle changes like weight management and sleeping position adjustments to CPAP machines that keep airways open.
Addressing sleep apnea early protects your
