Causes of Obesity Hypoventilation Syndrome
In obesity hypoventilation syndrome (OHS), excess body weight impairs breathing, resulting in low oxygen levels and high carbon dioxide levels.
-
Fat around the abdomen and chest restricts lung expansion.
-
Weakness of respiratory muscles caused by obesity, which decreases the efficiency of breathing.
-
With OHS, the brain's response to high carbon dioxide levels is blunted.
Symptoms of Obesity Hypoventilation Syndrome
Common symptoms of OHS include:
-
Poor nighttime breathing causes daytime sleepiness.
-
Obstructive sleep apnea is often associated with loud snoring.
-
High carbon dioxide levels cause morning headaches.
-
Tiredness and lack of energy are symptoms of fatigue.
-
Breathing problems: Especially during physical activity.
-
Sleep deprivation can lead to depression or mood changes.
Diagnosis of Obesity Hypoventilation Syndrome
Diagnosis involves:
-
Examining obesity-related symptoms and breathing difficulties based on medical history and physical examination.
-
Oxygen and carbon dioxide levels are measured in arterial blood gases.
-
Polysomnography is used to evaluate sleep apnea and hypoventilation.
-
Testing lung capacity and function with pulmonary function tests.
Obesity Hypoventilation Syndrome Treatment
The goal of treatment is to improve breathing and reduce symptoms:
-
Symptoms can be significantly improved with diet, exercise, and possibly bariatric surgery.
-
Continuous or bilevel positive airway pressure (PAP) machines are used to support breathing during sleep.
-
In cases of severe hypoxia, additional oxygen may be required.
-
In some cases, diuretics or respiratory stimulants may be prescribed.
-
Dietary changes and regular physical activity are among the lifestyle modifications.
Prevention of Obesity Hypoventilation Syndrome
Maintaining a healthy weight and lifestyle is a preventive measure:
-
Obesity prevention through a healthy diet.
-
Exercise supports weight management and respiratory health.
-
The importance of routine medical check-ups: Early detection and management of obesity and related conditions.
-
Sedatives can further depress breathing, so avoid them.
In this overview, we discuss the causes, symptoms, diagnosis, treatment options, and prevention strategies of obesity hypoventilation syndrome.
