Bronchoconstriction Asthma Copd
Negative pressure: When you breathe in, your chest wall and diaphragm expand and create decreased pressure in your lungs. Because the bronchoconstriction is also inside your lungs, the negative pressure causes the airway to expand as well, and air flows in easily. When you breathe out, the chest wall and diaphragm relax, and pressure in the lungs increases. This snaps the airways closed again, like a valve. ...Read more
COPD may include chronic bronchitis, emphysema, or both. Chronic bronchitis is the production of increased mucus caused by inflammation. Bronchitis is considered chronic if you cough and produce excess mucus most days for three months in a year, two years in a row. Emphysema is a disease that damages the air sacs and/or the smallest breathing tubes in the lungs. ...Read more
Why is breathing in during inspiration not affected by bronchoconstriction (asthma/copd)? I need some advice.
Bronchoconstriction: Lung disease is defined as either restricted or obstructed. Bronchoconstriction is, by definition, an obstructed condition. Obstructed diseases limit the ability to exhale air out of the lungs. Asthma and COPD are examples of diseases that lead to airway obstruction, where exhalation is affected, not inhalation. ...Read more
Bronchoconstriction (asthma/copd) affects breathing out during expiration, but not breathing in during inspiration, how come?
This is a fancy term of when airway pressure is more on the outside of your airways and collapses as you exhale. This pressure difference happens at different stages of exhalation in copd.
With asthma there is narrowing of your airways from inflammation so this constricts the diameter and makes this worse. All due to airway pressure and "equal pressure point". Hope this helps! ...Read more
I have bronchoconstriction (asthma/copd) affects breathing out during expiration, but not breathing in during inspiration. Why, what to do?
Typical symptoms: This is a common symptom for those with airway obstruction be it from asthma or copd. You need to get an assessment to determine what kind of medications may relieve your symptoms. Inhaled steroid, inhaled bronchodilator, and inhaled anticholinergic are the most common drugs used in your condition. Most of these drugs need to be used regularly. ...Read more
Pressure.: Long story...essentially, the pressure pushing upon the airways with expiration causes the airways to close upon themselves, causing air trapping which is one of the hallmarks of COPD and the other obstructive lung diseases. ...Read more
Probable: There are studies showing that Spiriva provides as much bronchodilation as beta agonist (albuterol etc). In selected cases, inhaled steroid, long-acting bronchodilator, and antimuscarinic (Spiriva) are required to control asthma. This same combination are also used on COPD although inhaled steroid may not be needed for a high % of COPD patients. ...Read more
NO: Singulair (montelukast) in indicated for asthma prophylaxis and chronic treatment, for seasonal and perennial allergic rhinitis, for prevention of exercise-induced bronchoconstriction. There is no indication to use in COPD — different mechanism of the disease. If you have allergic rhinitis which worsen your COPD symptoms — probably it could be beneficial. ...Read more
No, but don't help: Benzos won't exacerbate the underlying medical condition, but because they tend to cause suppression of the respiratory center in the brain, they can make it harder for your body to respond optimally to its internal compensatory mechanisms as well as to medications. ...Read more

I was told that I have either borderline asthma, asthma undiagnosed as a child or mild copd. I have no symptoms. Why no straight answer?
Does asthma turn into copd? If not, are they related? I don't smoke, had asthma since birth. Can I prevent longterm worsening of asthma somehow?
Yes: Asthma is leading chronic childhood disease affecting approximately 10 percent of the population nationally, chronic obstructive pulmonary disease (COPD) is leading chronic adult disease and third leading cause of death and second leading cause of disability. Some patients with both asthma and copd. Direct correlation is between severity of asthma and copd. Severe asthma 32x more likely get copd. ...Read more
What's the differance in bronchiectasis vs asthma COPD emphasima. What there similarities between the other disease's. I can't stop coughing at night?
Complicated: Bronchiectasis is due to chronic infection damaging the ends of bronchioles and creating a haven for chronic infection. Asthma is due to reactive airway disease making it difficult to get air out. COPD is a complex process and can involve emphysema and brochiectasis. See your doctor to figure out why you are coughing. Without more info cannot diagnose this. ...Read more
Asthma vs COPD : There is significant overlap. COPD is usually less reversible and caused by scarring due to smoking in most cases, where asthma is often allergic in cause. New evidence suggests maybe the smokers who get COPD where people with mild undiagnosed asthma, and some asthma patients don't reverse well at all! Some patients carry a dual diagnosis, and the medications used are often the same. Good Question ...Read more
COPD is in smokers: Both conditions represent chronic lung diseases. You are unlikely to get COPD if you never smoke cigarettes. Asthma is more likely to be genetic and run in families. Many people that suffer from allergies suffer from asthma as well. COPD flare-ups tend to be sporadic and require inhalers, steroids, and antibiotics. Asthma tends to require regular use of controller medication. ...Read more
Absolutely: Asthma and COPD are technically two separate processes, though more research is showing similarities between the two. Both conditions are considered "obstructive" processes; that is, they obstruct air flow from the lungs out into the environment. Asthma typically affects the smaller airways, while COPD mostly affects the alveoli -- tiny air sacs at the very end of our airways. ...Read more
Many Problems: COPD and Asthma are certainly the most common causes of a need for an inhaler, but there are other causes as well. Some might be exercise induced bronchospasm, acute illness like bronchitis or asthma (if it helps with symptoms), Chronic Bronchitis, Chronic Cough, or Chronic Eosinophilic Bronchitis. Sometimes inhalers are used at the doctor's discretion. ...Read more
Breathing Tests: COPD and asthma both present with airway obstruction however timing of presentation is helpful to determine cause. Asthma usually presents in childhood but can present in adults, however COPD usually presents only in adults over the age of 40 who are current or former smokers. Spirometry or Pulmonary Function Testing can differentiate between these two conditions. See an Allergist or Pulmonologist ...Read more
A few things: First- quit smoking if you do!!. I can't emphasize this enough. Secondly, get tested to confirm you have both conditions. Thirdly- get treated. Controller inhalers and rescue inhalers are the mainstay for asthma and is some cases COPD as well. Try to stay away from "triggers" that cause asthma attacks or COPD exacerbations if you can. Good Luck ...Read more
Diagnosed 10yr ago with asthma, COPD and sarcoid. All recent test results now say only sarcoid. Can asthma and COPD disappear?
Yes: Asthma oftne disappears. 'Copd' is a measurement on spirometry, not a real disease; patients with asthma will test as having 'copd' much of the time. Now please forgive me. You're smoking up to two packs a day. This is a terrible idea if you have a history of asthma / 'copd' and bad even if you don't or only have sarcoid. Please talk with your physician about smoking cessation. Thanks. ...Read more
No cures for either: The conditions you mention are managed with the aid of medication, not cured. Once you have them, they are present to some degree indefinitely. ...Read more
