The patient's symptoms, weight loss, exercise intolerance, exacerbations, health-related quality of life, health resource consumption, and mortality are all repercussions of COPD. The most important consequence of COPD is that it causes death. In fact, COPD is a leading cause of death worldwide. COPD affects the lungs' airways to such an extent that they no longer produce the mucus they were designed to produce. This leads to problems breathing, losing weight, exercising, and sleeping. There are two main types of COPD: chronic obstructive pulmonary disease (COPD). This means your lungs are damaged by smoking or another respiratory condition such as asthma. Obstructive sleep apnea (OSA) is a condition in which you don't get enough deep breaths while you sleep. This can lead to daytime drowsiness and fatigue, a poor memory, and increased risk of injury due to lack of oxygen during sleep. There are different treatments for COPD depending on what type you have. If your lung problems are caused by cigarette smoke, stopping smoking will help relieve your symptoms and prevent further damage to your lungs. If your breathing problems result from other factors such as high blood pressure, heart failure, or obesity, treating the underlying problem may be all that's needed to improve your COPD symptoms.
