Obesity And Lung Capacity
The definition started with Louis Israel Dublin, chief statistician of the Metropolitan life insurance company, in the early 1940s, as a BMI >25 (definitely >30) for people in their 20's based on retrospective observational life insurance data of the age at which people died later in life. This was subsequently adopted by the medical disease industry. However, BMI is ...Read more
Lots of research: There is a lot of research going on about this topic actually. One of the things that is very common is that as abdominal and chest girth become more of an issue, stomach contents can get pushed up into the esophagus and cause reflux. That reflux material and gas can actually wash down into the lungs creating bad reaction and asthma attack. ...Read more

Exercise: It appears that all of your cardiac tests are normal, and that is very good. I do not see that you listed any lung evaluations, such as pulmonary function tests. This is a suggestion if you continue to have air hunger, as PFT can diagnose asthma or other lung conditions. This may be a matter of being out of shape because of your being overweight. See your doctor for an individualized exercise RX ...Read moreSee 2 more doctor answers
Need to find out why: During a pulmonary function test, there are typically three measurements taken. First, how well the air "moves" in and out of the lungs. Copd, asthma, bronchitis, etc are things that would cause it to drop. Second, the efficiency of oxygen transfer is measured, the diffusion. Last, the lung sizes are measured. Again, which value is down and why its down is the most important thing to find. ...Read more
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
