Asthma Vs Copd: What’s The Difference

Difference Between Asthma & COPD

It is no surprise that asthma and chronic obstructive pulmonary disease are often mistaken for one another they are both conditions that affect the lungs and make breathing more difficult. Despite their many similarities, asthma and COPD are not the same. In honor of November being National COPD Awareness Month, it is time to finally clear up the question of whether asthma and COPD are the same thing.

Below, we will look at the definitions of the two diseases, along with the symptoms, causes and treatments for each. We will also discuss when to see a medical professional for lung damage to help raise COPD awareness this month.

Is Dlco Helpful In Predicting Exercise Oxygen Desaturation

Studies from the 1980s indicated that DLCO was more useful for excluding exercise oxygen desaturation during exercise in COPD patients than in ruling it in., Owens and colleagues found that a DLCO of 55% predicted had 82% specificity and 100% sensitivity for excluding exercise-induced O2 desaturation in COPD. Ries and co-workers found that an FEV1/FVC 0.50 and DLCO 20 mL/min/mm Hg were 100% predictive in excluding a fall in exercise PO2 in 40 patients with COPD.

More recently, using a large database in patients with mixed pulmonary diseases, the ability of DLCO to predict exercise O2 desaturation 4% on a 3-min step-test was examined. Obstructive lung disease was present in 74% of subjects, and restrictive diseases in 5.6%. A low DLCO was present in 56% of patients with restriction, and 33% of patients with an obstructive pattern. If DLCO was low, the odds ratio was 34 for O2 desaturation in restrictive patients and 18 in the obstructive group. Overall, for all subjects, a cut point of 62% predicted was most useful. When DLCO was < 62% predicted, using the Miller et al reference equation, the sensitivity and specificity for O2 desaturation were both approximately 75%.

These studies suggest that a reduced DLCO is not sufficiently accurate to predict exercise O2 desaturation without directly measuring it. However, among patients with COPD, the presence of a low DLCO warrants measurement of exercise O2, often in conjunction with a 6-min walk distance test.

Pulmonary Rehabilitation For Copd

Pulmonary rehabilitation has clear benefits for patients with COPD. Exercise increases endurance, improves shortness of breath, increases maximal oxygen consumption, and improves quality of life. Numerous studies have documented improvement in symptoms, maximum oxygen consumption, and quality-of-life measures. A decrease in the number of hospitalizations has also been shown in patients who participate in pulmonary rehabilitation programs.

Benefits do vary among individuals, however, and consistent participation in an exercise regimen is necessary to maintain improvements. In addition, it has not been shown that pulmonary rehabilitation produces any change in pulmonary function tests or overall oxygen requirements for individuals.

Symptoms And Signs: 6 Similarities Between Copd Vs Asthma

COPD is caused by long-term exposure to lung irritants that damage lung cells. The main cause of COPD in the United States is cigarette smoke followed by other tobacco smoke . Other possible causes of COPD include chemical or toxic fumes, and inherited factors, like alpha-1 antitrypsin deficiency, but these causes are far less common than cigarette smoking.

Although cigarette smoke may trigger asthma in some patients, asthma triggers are different from person to person, and most commonly include airborne substances such as pollen, dust, mites, mold spores, pet dander, and/or many other substances. Inflammatory immune reactions to asthma triggers in the airways is the main cause of asthma.

Asthma and COPD  Overlapping Disorders or Distinct ...

Does it seem like you run out of breath easily? Do you sometimes cough when you catch your breath or have coughing episodes? If you answered yes, you may have a respiratory illness. If you Google your symptoms, the most common results will be asthma and COPD.

Running out of breath after minimal exertion and having coughing episodes are signs of asthma and chronic obstructive pulmonary disease . Both conditions have overlapping symptoms and are easily confused for one another, particularly for adult patients.

A comprehensive evaluation of your symptoms that includes a physical exam and laboratory tests, along with a review of your medical history, are necessary to make a clinical diagnosis of your respiratory illness.

Patients with either asthma or COPD need proper management of their symptoms in order to minimize the severity of their condition and live a normal life. Here are a few key differences between asthma and COPD.

Copd Causes Chronically Obstructed Airways

This may be due to airways that are drawn taught due to emphysema. It may be due to airway inflammation. This inflammation may be eosinophilic such as in asthma. This may be reversible with corticosteroids. But, inflammation may be neutrophilic and less responsive to corticosteroids. COPD inflammation may also respond to another type of bronchodilators called muscarinics. There are other treatments to help allay symptoms and slow the progression of the disease.

Copd Vs Asthma: Which Is Worse

| | | | | | | | |

Asthma and chronic obstructive pulmonary disease are diseases of the lung that have a lot in common, but they also have key differences. Both conditions have similar symptoms caused by swelling of the airways or airway obstruction. Airflow limitation commonly results in breathing difficulties, coughing, wheezing, chest tightness, and shortness of breath.

Symptoms from asthma, triggered by allergens or exercise, come and go. COPD symptoms that can be caused by long-term smoking or prolonged exposure to chemical irritants are persistent. With COPD, chronic inflammation results in irreversible damage to the tissues lining the airways as well as pathological changes to the lung.

Though both diseases are chronic, COPD is a progressive condition, meaning symptoms are constant and the condition gets worse over time. With asthma, measures can be taken to control the disorder and when managed properly, its possible not to experience any symptoms for extended periods of time. Its important to distinguish COPD from asthma to determine the best course of treatment. Lets investigate the similarities and differences between asthma and COPD.

Diagnosing Asthma And Copd

Whats the difference between asthma, COPD?

With all the similarities between asthma and COPD symptoms, it can be challenging to diagnose each disease correctly without mistaking one for the other. Asthma is the most common alternative diagnosis for COPD. However, it is important to correctly identify which condition a patient is dealing with so they can receive the proper treatment.

When a patient has symptoms that pertain to both asthma and COPD, there are a few key factors that differentiate the two. To develop an accurate diagnosis, medical professionals will ask patients dealing with breathing issues specific questions about their symptoms, such as what time of day they feel the worst. They will also inquire about the patient’s medical, family and smoking histories and exposure to irritants, as well as gases or vapors.

Evaluating Asthma And Copd Symptoms And Causes

Because they are both lung diseases that inhibit regular breathing, asthma and COPD share many similarities in both symptoms and causes. The inflammatory immune reactions that cause an asthma attack are often triggered by airborne substances like smoke, dust, pollen, pet dander, mites and mold spores. COPD is caused by long-term exposure to lung irritants, such as cigarette smoke, toxic fumes and chemicals, which results in damaged lung cells.

While there are many external factors like tobacco smoke and secondhand smoke that can cause COPD or asthma, inherited genetic factors can also play a role in susceptibility to either of the diseases. For instance, alpha-1 antitrypsin deficiency is also referred to as inherited emphysema. Because of their similar causes and the way they affect the lungs, COPD symptoms can oftentimes look like an asthma attack and vice versa.

Here are the symptoms that may be found in both those with asthma and those with COPD:

Although the symptoms of COPD and asthma have a great amount of overlap and similarities, there are some subtle differences among them. For example, the chronic cough often experienced by those with COPD tends to produce far more phlegm and mucus than the amount produced by asthma. For this reason, a chronic cough is much more common in those with COPD than with asthma.

The Type Of Inflammation May Be Different For Both

Asthma inflammation tends to be eosinophilic. This type of inflammation responds well to corticosteroids. Asthma is also reversed with medicines that dilate airways. So, bronchodilators called beta 2 adrenergics are also helpful. Often, combination inhalers provide both types of medicine. These may help asthmatics obtain good control of their disease. This means they should be symptoms free on most days.

Can Asthma Lead To Copd Later

Not everyone with asthma goes on to develop COPD. However, having asthma as a child or younger adult can affect how well your lungs develop, and that can increase your chances of having COPD when youre older. One recent study reported that over one in 10 children with persistent asthma went on to have COPD as a young adult.

This means that if you have asthma, its even more important that you dont smoke. Quitting will help to lower your chance of developing COPD in later life as well.Learn more about:

Is It Really Copd The Difference Between Asthma And Copd

Copd Versus Asthma Symptoms

Chronic obstructive pulmonary disease is an ongoing lung disease that makes it difficult to breathe. Its also a disease thats often misdiagnosed as asthma. Although most patients are correctly diagnosed by their doctors as having either asthma or COPD, up to 20% of patients with respiratory symptoms are difficult to accurately diagnose.

Because differentiating between asthma and COPD is essential for determining the appropriate treatment, understanding what sets these two lung diseases apart may help you decide whether or not you should further discuss your diagnosis with your doctor, or seek a second opinion.

How To Distinguish Between Copd And Asthma

Daniel More, MD, is a board-certified allergist and clinical immunologist. He is an assistant clinical professor at the University of California, San Francisco School of Medicine and currently practices at Central Coast Allergy and Asthma in Salinas, California.

Chronic obstructive pulmonary disease and asthma share a variety of common symptoms, which can make it difficult to distinguish between the two, at least initially. Because COPD has a certain stigma in our society that many patients do not like, some patients with COPD are more apt to say they have asthma. As with any condition, its important to determine the correct diagnosis to ensure that youre getting proper treatment.

What Are The Stages Of Copd

Doctors generally use the Global Initiative for Chronic Obstructive Lung Disease Program to stage COPD. These staging guidelines have been proven to be consistent and accurate by doctors and scientists. Other methods can be used to stage COPD, but they may be influenced by other factors.

There are many treatment options and ways to manage COPD. The newest 2017 guidelines emphasize the use of combined bronchodilators as first-line therapy for COPD. Doctors recommend vaccinations for people with the condition to decrease the risk of lower respiratory tract infections. Alterations in health-related behaviors is emphasized. Spirometry measurements can help determine the extent of obstructive lung disease. As COPD progresses, oxygen therapy, especially if you have obstructive sleep apnea, may help improve your survival.

Like COPD, there are many treatment options and ways to manage asthma. Your primary care doctor and/or an allergist will discuss and suggest the best choice of treatment and management drugs for you. Medications used include corticosteroids, short acting beta agonists , and occasionally anticholinergic medications for severe exacerbations.

Emergency treatment of life-threatening asthma or COPD may involve intravenous corticosteroids, intubation, mechanical ventilation, and oxygen treatment until the crisis is resolved.

Is Air Flow Obstruction A Risk Factor For Lung Cancer

Cigarette smoking is the main risk factor for lung cancer, accounting for roughly 85% of cases. Multiple studies have suggested that air flow obstruction is a risk factor for lung cancer independent of smoking, but the role of radiographic evidence for emphysema is less clear. A recent study from the Mayo Clinic enrolled 1,520 patients who were followed for 4 years for the development of lung cancer . When analyzed as a continuous variable, reduced FEV1 and FEV1/FVC were associated with a subsequent diagnosis of lung cancer, with an odds ratio of 1.15 and 1.29 , respectively. When analyzed as a categorical variable, more severe air flow obstruction was associated with greater likelihood of lung cancer . There was no statistical association between percent volume of emphysema on chest CT scan and prevalent or incident lung cancer . Total lung volume measured on chest CT was significantly higher in patients with lung cancer than control subjects .

Is Chronic Asthma The Same As Copd

Asthma and COPD differences / treatment (How to tell the difference)

Chronic asthma and COPD can have similar symptoms, but they are considered distinct conditions. COPD refers specifically to chronic bronchitis, emphysema or both.

Other differences include the fact that asthma tends to start during childhood, while COPD is more likely to appear among adults who smoke.

Similarities And Differences In Regular Standard Treatment Of Asthma And Copd

  • In both diseases the adequate treatment may reduce symptoms and number of exacerbations and improve the quality of life.

  • Treatment of asthma is characterized by suppression of inflammation.

  • Treatment of COPD is characterized by decreasing of symptoms.

The GOAL of treatment in ASTHMA is to: reduce inflammation and to achieve¬łtotal control . The GOAL of treatment in COPD is to: reduce symptoms, prevent exacerbations and decrease mortality . In both asthma and COPD almost the same drugs are used, but not in the same order and the same efficiency in treatment.

Differences Between Asthma & Copd

It’s easy to get confused between asthma and chronic obstructive pulmonary disease . After all, these two conditions share some of the common symptoms such as wheezing, coughing, shortness of breath and the inability to get air into the lungs. Not only they share the same symptoms but they also share the same medications for treatment. So, what are the differences between them?

What Are Symptoms Of Emphysema

Symptoms of emphysema may include coughing, wheezing, shortness of breath, chest tightness, and an increased production of mucus. Often times, symptoms may not be noticed until 50 percent or more of the lung tissue has been destroyed. Until then, the only symptoms may be a gradual development of shortness of breath and tiredness , which can be mistaken for other illnesses. People who develop emphysema have an increased risk of pneumonia, bronchitis, and other lung infections. See your doctor if any of these symptoms arise:

  • Shortness of breath, especially during light exercise or climbing steps
  • Ongoing feeling of not being able to get enough air
  • Long-term cough or smokers cough
  • Wheezing

With asthma, find out your triggers and do what you can to avoid them. Be sure to keep your inhaler accessible as you never know when an attack will hit and manage your symptoms accordingly.

Smoking is often the cause of COPD the best thing you can do is divorce yourself from the habit and start making health a bigger priority. Other triggers to avoid are second-hand smoke, dust, and pollutants. These may cause further damage to your lungs and increase the speed of COPD symptoms.

Asthma and COPD are separate diseases that can occupy the same space. Having asthma doesnt mean you will also contract COPD, but always exercise caution with your lungs. You only get one set of lungs, so take care of them as best you can

Difference Between Asthma And Chronic Obstructive Pulmonary Disease

July 21, 2017 by Rachna C

The respiratory disease which is diagnosed during childhood, resulting in shortness of breathing, dryness of a cough, chest tightening is called asthma. On the other hand, COPD also known as Chronic Obstructive Pulmonary Disease is also one of the respiratory disease, which occurs after the age of 4o, and the condition gets progressively worse with age.

The cells of our body need oxygen to work and grow, and this oxygen is taken by the lungs through the simple process of breathing. Usually, in a day, we breathe 25,000 times a day. But people suffering from any lungs infection experience the problem in breathing.

Lung diseases are one of the most common medical conditions existing in the world. There are many kinds of lungs infections like bronchitis, cystic fibrosis, emphysema, COPD, asthma, pneumonia, tuberculosis, etc. pollutions, infections, allergens, smoking or genetics can be the major cause of all these problems.

In this article, we will mark the vital difference between the two common respiratory disease asthma and the COPD. We will also discuss their causes, symptoms, and treatment.
