Obesity causes mechanical compression of the diaphragm, lungs, and chest cavity, which can lead to restrictive pulmonary damage. Furthermore, excess fat decreases total respiratory system compliance, increases pulmonary resistance, and reduces respiratory muscle strength.

Obesity hypoventilation syndrome
Hypercapnic respiratory failure and cor pulmonale are frequently observed in obesity. In the absence of other known causes of respiratory failure, this syndrome, which was first described 50 years ago,84 is now termed obesity hypoventilation syndrome.
Does obesity reduce lung capacity?
Although obesity significantly reduces functional residual capacity (FRC) and expiratory reserve volume (ERV) [15, 24, 25], it has very little effect on residual volume (RV) and total lung capacity (TLC).
Why do overweight people have breathing problems?
Obesity can lead to changes in the way you breathe. With weight gain, fat tends to accumulate around your neck and abdomen, placing greater pressure on your breathing muscles. This fat, called adipose tissue, also releases hormones called cytokines that are linked to inflammation.
Will losing weight help me breathe better?
Patients who completed the 6-month weight loss program experienced improvements in respiratory health status, irrespective of weight loss. Conclusion: We concluded that weight loss can improve lung function in obese women, however, the improvements appear to be independent of changes in airway reactivity.
Can obesity cause chronic cough?
The crucial role of obesity has been highlighted in the development and progression of many respiratory diseases. According to the results of epidemiological studies, obesity, particularly abdominal obesity, may also be associated with chronic cough (CC).
Does obesity affect oxygen levels?
Obesity affects lung function and diminishes oxygen exchange.
How can lung capacity be increased?

Can belly fat make it hard to breathe?
Extra fat on your neck or chest or across your abdomen can make it difficult to breathe deeply and may produce hormones that affect your body’s breathing patterns. You may also have a problem with the way your brain controls your breathing. Most people who have obesity hypoventilation syndrome also have sleep apnea.

Causes of shortness of breath
Common causes include asthma, a chest infection, being overweight, and smoking. It can also be a sign of a panic attack. But sometimes it could be a sign of something more serious, such as a lung condition called chronic obstructive pulmonary disease (COPD) or lung cancer.
Can obesity hypoventilation be cured?
Obesity hypoventilation syndrome (OHS), can be a serious, but treatable, complication of being obese. dioxide) in the blood. Pulse oximetry however is not as accurate as a blood sample from your artery. A chest x-ray and pulmonary function tests may be done to rule out any other causes of your breathing difficulty.
Can losing weight stop shortness of breath?
In conclusion, moderate weight loss was effective in reducing breathlessness on exertion in obese women who experienced DOE at baseline.
How come when I walk I get out of breath?
People can experience shortness of breath while walking for a number of reasons. Sometimes, this occurs as a result of conditions such as anxiety, asthma, or obesity. Less commonly, shortness of breath signals a more serious underlying medical condition.
