Increased Heart Rate
When the airways in the lungs become narrow and restricted, it leads to a decrease in the delivery of oxygen-rich blood to the various tissues in the body. This places an additional burden on the heart, which is responsible for pumping oxygenated blood to all the organs and tissues. In order to compensate for the reduced oxygen supply, the heart starts beating at a faster rate. Hence, an increased heart rate is often observed as a typical symptom of advanced or severe Chronic Obstructive Pulmonary Disease (COPD).
Weight Loss and COPD
Weight loss is a prevalent issue in individuals with advanced cases of COPD. The restricted breathing associated with the condition causes the body to require more energy to carry out essential functions. Unless people with COPD increase their caloric intake, they end up burning more calories than they consume, resulting in weight loss.
