Obstructive Sleep Apnea - a Frequent Undiagnosed Condition

Introduction:

Obstructive sleep apnea, otherwise called OSA, is a condition characterized by obstruction of the upper airway, especially during sleep due to lax airway and narrowing of the airway due to obesity. It is a potentially serious sleep disorder, as it causes your breathing to start and stop repeatedly when you sleep. Snoring is the most important sign of sleep apnea. As air squeezes through the narrow airway, the person snores. If left untreated, sleep apnea can lead to severe health conditions, such as hypertension, stroke, heart problems, and diabetes. Diagnosing and treating this condition promptly is the key to prevent complications.

What Are the Symptoms of Obstructive Sleep Apnea?

Obstruction of the upper airway leads to a temporary stoppage of respiration, increased sympathetic drive, and increased pulse rate and blood pressure. These episodes result in decreased oxygen supply to the brain and other parts, causing the following symptoms:

• Loud snoring.

• Poor sleep quality.

• Daytime drowsiness.

• Feeling tired in the morning.

• Frequent headaches.

• Feeling grumpy.

• Forgetfulness.

• Gasping or choking at night.

• Drowsiness.

• Night sweats.

• Poor sex drive.

• In severe cases, leg edema.

Daytime drowsiness increases the risk of road traffic accidents. As mentioned above, it also increases the risk of stroke, heart attack, and lung problems (pulmonary hypertension). In case if one's partner complains about them snoring or getting up in the middle of the night gasping or choking or feel tired and drowsy during the day, it is best to consult a doctor.

What Causes Obstructive Sleep Apnea?

In OSA, the muscles in the throat that support important structures, such as the soft palate, uvula, tonsils, and tongue relax too much. When these muscles relax, the airway constricts and prevents breathing for 10 seconds or longer. This lowers the level of oxygen in the blood and results in the buildup of carbon dioxide.

It can also deprive the brain of oxygen, which makes the brain to awaken a person for a brief moment so that the airway gets reopened. Most people do not realize that they woke up during the night. Some people get up snorting, choking, or gasping for air.

It is necessary to adequately investigate through ENT examination if one has any symptoms of nasal stuffiness and recurrent tonsillitis to rule out nasal causes of obstruction. Sometimes, thyroid problems will cause obstruction. Altered lipid profile and sugar HbA1c that is, dyslipidemia and diabetes are the frequently associated problems. Vitamin D deficiency is also responsible.

Risk Factors:

The following factors might increase the risk of a person developing obstructive sleep apnea:

1. Obesity - The majority of people who suffer from sleep apnea are overweight or obese. It is due to the fat deposits surrounding the upper airway.

2. Hypertension - People with high blood pressure commonly have sleep apnea.

3. Obstructed airway - Some people have naturally narrow airways, which when combined with tonsils or adenoids enlarged results in OSA.

4. Nasal congestion - Chronic nasal congestion narrows the airway, which leads to OSA.

5. Asthma - Some studies have shown that asthma increases the risk of sleep apnea.

6. Diabetes - OSA is common in people with high blood sugar.

7. Smoking - People who smoke are at risk.

8. Sex - Men are more susceptible than premenopausal women, but the risk increases in women after menopause.

9. Genetics - The risk increases if any of the family members have OSA.

10. Other factors - Lower jaw shorter than the upper jaw (retrognathia), people with a large tongue or narrow palate.

What Are the Possible Complications of Obstructive Sleep Apnea?

The possible complications of OSA include:

• Daytime sleepiness.

• Difficulty concentrating.

• Hypertension.

• Abnormal heart rhythms.

• General anesthetics can worsen sleep apnea.

• Glaucoma.

• Sleep deprivation.

How Is Obstructive Sleep Apnea Diagnosed?

The specialist might perform the following tests if he or she suspects obstructive sleep apnea:

Polysomnogram - This sleep study is performed by connecting you to various machines while you sleep. A polysomnogram measures the activity of various organ systems during sleep, which includes:

1. Electroencephalogram (EEG) - measures brain waves.

2. Electromyogram (EMG) - measures muscle activity.

3. Electroculogram (EOM) - measures eye movement.

4. Pulse oximetry test - measures the oxygen levels in the blood.

5. Electrocardiogram (EKG or ECG) - measures heart rate or rhythm.

6. Arterial blood gas analysis (ABG) - measures levels of oxygen and carbon dioxide.

How Is Obstructive Sleep Apnea Treated?

The treatment options include:

1. Weight reduction - You need to have a low-fat and low-calorie diet to lose weight. A cure for this particular disease is weight reduction. So, a healthy lifestyle including both a healthy diet and regular exercise is the central goal in the management of OSA.

2. CPAP (continuous positive airway pressure) - It is a mask device that provides pressure during inspiration and expiration during sleep in order to keep your airways patent and avoid OSA.

3. Nasal decongestants - They help relieve snoring in mild cases.

4. Bilevel positive airway pressure (BiPAP or BPAP) - In case CPAP therapy not being effective, BiPAP are used.

5. Positional therapy - As sleeping on your back can worsen sleep apnea, patients are encouraged to sleep in other positions.

6. Surgery - Uvulopalatopharyngoplasty (UPPP) is the most commonly done surgery for sleep apnea. It involves the removal of extra tissues from the back of the throat.

Also, regular exercise is vital. Chest physiotherapy and yoga will be helpful.

Conclusion:

Having symptoms such as snoring, interrupted sleep, unrefreshed sleep, morning headaches, daytime sleepiness, and so on accompanied with being obese with a short and wide neck could indicate that one is suffering from obstructive sleep apnea, which is frequently an undiagnosed condition and has multiple adverse effects on one's body. For an in-person consultation, one needs to visit a sleep specialist or pulmonologist. Always, one must talk to a doctor if they have daytime drowsiness or sleep problems. The symptoms can be effectively managed with the help of different treatment options. Treatment options like using a device that keeps the airway open during sleep or a mouthpiece to keep the jaw forward while sleeping can be effective. Some cases can be treated with surgery.
