How Does Obesity Cause Shortness of Breath?

Dr.Akshay Budhraja, 3 mins read

Obesity is not just a cosmetic concern; it's also a risk factor for various medical conditions. One such condition, which we will discuss in this blog, is shortness of breath. Many people with obesity often experience shortness of breath, also called obesity hypoventilation syndrome or Pickwickian syndrome.

Its symptoms are, up to an extent, similar to Obstructive Sleep Apnea. It has been seen that many people with Obstructive Sleep Apnea also experience Pickwickian syndrome. 

Link Between Obesity & Breathlessness

Obesity is a condition in which excess fat builds up in the neck, chest and abdomen. Because of this, when you take a deep breath, your lungs have to do a harder job to expand to full capacity. With time, the bottom of the lungs progressively collapses, which, in turn, leads to shortness of breath.

Usually, people experience shortness of breath when lying down on a surface because the fat accumulated in their chest makes it harder for them to take a deep breath.  

It has also been seen that obesity hypoventilation syndrome causes too much carbon dioxide and less oxygen in the blood, which can amount to a serious condition with time. 

Symptoms

The common symptoms of obesity hypoventilation syndrome include dizziness, headaches, fatigue, breathlessness, daytime sleeplessness, loud snoring, choking and gasping at night, etc. The symptoms can worsen with the progression of the disease.

Diagnosis

If you suspect any of the symptoms mentioned above, immediately consult your doctor. He may measure your neck and waist circumference and check your height and weight for BMI (Body Mass Index). 

A waist circumference of more than 40 inches for men and 35 inches for women is considered abnormal. In addition, a BMI of 30 or above is considered obese.

To calculate your BMI, divide your weight (kg) by the square of your height (metres). For example, if the weight is 60 kg and the height is 1.52 metres, then the BMI will be 60/(1.52)2 = 60/2.31 = 25.97.    

The doctor may also take lung tests to check your lung’s performance and the amount of oxygen in your blood. 

Treatment

The best way to prevent and get relief from this disease is to adopt a healthy lifestyle and maintain a healthy weight. Consider yoga, cycling, cardio exercises and respiratory rehabilitation programs. Not only does this help you get in shape, but it also makes you feel better.

If the problem is severe, you may need a CPAP (continuous positive airway pressure) machine or another breathing device at night to improve your blood oxygen level and keep your airways open. 

In some circumstances, you may need to take medicines and even undergo surgery to remove extra fat. 

Takeaway!

Excess fat accumulation in the neck, chest, and belly area can result in difficulty breathing, which is not good for overall health. Maintaining a balanced diet and including healthy exercises in your routine can keep you away from this disease. If you're diagnosed with this disease, consult with a doctor.
