The accumulation of more fat in the chest and abdomen will make it tough for your lungs to expand in an upright position. Inadequate air exchange causes shortness of breath when large lung sections are not used.
Excess weight against the chest wall also makes it harder for the muscles to draw in a deep breath and to breathe quickly enough. This worsens the brain's breathing control. As a result, the blood contains too much carbon dioxide and not enough oxygen.
If you're overweight, losing a few extra pounds can help you breathe better. People who are obese may have shortness of breath. Excess belly fat can reduce the amount of air your lungs can hold when you inhale. Losing weight makes it easier to breathe and move.
Excess fat on the neck, chest, or across the belly can make it difficult to breathe deeply and may produce a hormone that affects the body's breathing patterns. Excess belly fat may affect breathing by pushing on the diaphragm and chest wall, making it harder for the lungs to fill with air.
The correct answer is that fat is converted to carbon dioxide and water. You exhale the carbon dioxide and the water mixes into your circulation until it's lost as urine or sweat.
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.
Losing 5-10% of your weight has been shown to reduce breathlessness and improve lung function. “This can make a big difference to your day-to-day life,” says Slimming World dietitian Carolyn Pallister. “Being able to walk upstairs without getting out of breath sounds simple, but it can be life-changing.”
After weight loss, lung volume subdivisions at rest were increased (p < 0.05) and were moderately associated (p < 0.05) with changes in weight. End-expiratory lung volume (%Total Lung Capacity) increased at rest and during constant load exercise (p < 0.05).
The reasons people who are obese often develop respiratory problems, from simple shortness of breath to a potentially life-threatening condition known as obesity hypoventilation syndrome (OHS), remains somewhat a mystery.
Many overweight people have built up resistance to a hormone called leptin. Fat cells in your body make leptin, and leptin tells your body when you have enough stores of fat, decreasing your appetite.
If you frequently overbreathe, you may have a medical problem called hyperventilation syndrome. When you're overbreathing, you might not be aware you're breathing fast and deep. But you'll likely be aware of the other symptoms, including: Feeling lightheaded, dizzy, weak, or not able to think straight.
Researchers found that not only do subcutaneous fat reserves act as a layer of insulation, hindering heat exchange and therefore the cooling process, but that overweight people produce more heat.
Weight loss has been shown to result in improvements in overnight oxygen saturation in parallel with increase in the FRC and ERV (31). In addition to reducing the reserve of oxygen in the lung, excess body weight affects the ventilation-perfusion ratio, another important determinant of ΔSaO2 (23).
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.
BREATHING PATTERNS OF OBESE PATIENTS
In four studies, the mean respiratory rate of obese subjects ranged from 15.3 to 21 breaths per minute, while that of normal subjects ranged from 10 to 12 breaths per minute. Tidal volume tends to be significantly lower in obese subjects,3–5 although this finding is not universal.
Include a lot of colourful fruits and veggies to your diet. Exercise regularly. Even going for a walk will help. Maintain a healthy lifestyle and you will bring down the risk of fatty lungs as well as many other health disorders.
Anthropometric measurements
Tall stature is typically associated with higher static lung volumes and capacities [24]. Increased body weight is associated with lower lung volumes in obese subjects [25].
Known as Long-breath diet by Ryosuke, this Japanese technique for losing belly fat quickly involves standing in a certain position, taking 3-second breath and exhaling strongly for 7 seconds. It has been previously found that breathing exercises can help you with weight loss.
Fat leaves the body as carbon dioxide when you breathe and is also released as water through urine and sweat. So if you think about it, that backs up why exercise is an important part of weight loss. Your body disposes of fat through sweat, urine, and exhaled air.
