Obstructive Sleep Apnea: Symptoms, Causes, and Treatment Options

Obstructive sleep apnea is the most common sleep-related breathing disorder. It happens when the muscles at the back of your throat relax too much during sleep. When those muscles relax, the airway narrows or closes. Your brain briefly wakes you to reopen the airway. This cycle can repeat more than five times per hour, all night long.

Most people with obstructive sleep apnea do not know it is happening. They do not remember waking up. But the interruptions prevent deep, restful sleep. The result is fatigue, mental fog, and other problems during the day.

The most common nighttime sign is loud snoring. Other signs include pauses in breathing, gasping or choking during sleep, and frequent urination at night. During the day, people often feel excessively sleepy. They may wake with a dry mouth, a sore throat, or a headache. Difficulty concentrating, mood changes, and high blood pressure are also common.

Not everyone who snores has obstructive sleep apnea. But if snoring is loud and interrupted by silence, that is a reason to see a doctor. Falling asleep during the day, especially while working or driving, is a serious warning sign.

Anyone can develop obstructive sleep apnea. But certain factors increase the risk. Excess weight is the most significant. Fat deposits around the upper airway can block breathing. Being male also increases risk. Men are two to three times more likely than premenopausal women to have the condition. Risk in women rises after menopause. Other risk factors include older age, a family history of sleep apnea, a naturally narrow airway, chronic nasal congestion, and smoking.

Left untreated, obstructive sleep apnea can cause serious health problems. It puts strain on the heart and blood vessels. Blood oxygen levels drop repeatedly through the night. This raises blood pressure and increases the risk of heart attack, heart failure, stroke, and irregular heart rhythms. People with the condition are also at greater risk of accidents due to daytime sleepiness.

Several treatments are available. The most common is a CPAP machine, which uses steady air pressure to keep the airway open during sleep. A mouthpiece can also help by moving the lower jaw forward to keep the airway clear. In some cases, surgery is an option. For people with obesity, weight loss can significantly improve or even resolve symptoms.

If you or a partner suspect sleep apnea, a healthcare provider can evaluate your symptoms and recommend testing. Early treatment makes a meaningful difference in health and quality of life.
