Is Asthma Restrictive Or Obstructive
Obstruction: Airway "obstruction" refers to limitation of air flow through the airways. Asthma is a disease of chronic airway inflammation that can "obstruct" flow. "restriction" refers to processes that keep the lungs from opening fully when you inhale. Restriction can result from fibrosis, or thickening, of the lung. It can even be from something as simple as obesity that keeps you from breathing deeply. ...Read more
Asthma is a disease of the lungs caused by chronic inflammation of the airways most often caused by allergies. This inflammation results in airway swelling and hyperactivity leading to difficulty breathing, shortness of breath, dry cough, etc. MIT is a diagnosis made by combining clinical ...Read more
Which of these are restrictive: obstructive pulmonary diseases are asthma, chronic bronchitis and emphysema?
Restriction: Airway "obstruction" refers to limitation of air flow through the airways. "restriction" refers to processes that keep the lungs from opening fully when you inhale. Restriction can result from fibrosis, or thickening, of the lung as with diseases like idiopathic pulmonary fibrosis. It can even be from something as simple as obesity or muscle weakness that keeps you from breathing deeply. ...Read moreSee 2 more doctor answers
What to do if I know obstructive pulmonary diseases are asthma, chronic bronchitis and emphysema but what are the restrictive ones?
See below: Exam question? The interstitial lung diseases (there are many) like Interstitial pneumonias from collagen vascular disease or idiopathic, Bronchiolitis Obliterans Organizing Pneumonia (BOOP), Respiratory Bronchiolitis Associated Interstitial Lung Disease (RBILD), Drug induced lung disease; also Obesity, Pregnancy, and Cirrhosis with ascites. Many others. ...Read more
I have small airway disease, not asthma, which means I have problems getting air out of my lungs. Is this restrictive or obstructive? The doctor didn't put me on any treatment.
Lung volumes show significantly decreased functional residual capacity , but otherwise normal, what's this mean? Doc says I have asthma but decreased frc online says restrictive disease im scared!
Decrease FRC: Frc is the volume of air present in the lungs at the end of passive expiration. Obesity and posture will decrease the frc. I am imaging you just got a complete pulmonary function test. In asthmatic patient, the FRC can be normal or high if associated with emphysema or more chronic obstructive conditions. Low FRC with normal pft is not diagnostic of restrictive lung disease. Trust your lung doctor. ...Read moreSee 1 more doctor answer
If pulmonary function test shows a mild obstructive ventilatory defect with normal volumes and high dlco but not a smoker and don't have asthma, is this finding significant?
Need more info: You don't mention why you had pfts in the first place. The combination of a mild obstructive defect with normal volumes and high diffusion is typical of asthma. Without clinical data i can't be more specific. People with allergic rhinitis may have sub-clinical asthma. Which form of Hydrocortisone are you taking? Tablets? Topical? ...Read moreSee 2 more doctor answers
Pft shows high dlco and frc, normal volumes, mild obstructive ventilatory defect, increased capillary blood volumes, in context of ctd and cryofibrinogenemia (no asthma or smoking), what can be cause?
Unrelated: Ctd is usually associated with a diffusion problem in the lung but your showed above normal dlco. The study also showed mild airway obstruction which, along with the elevated dlco and FRC may well be from asthma. I am not away of any cryofibrinogenemia link to your lung function findings. See an allergist or pulmonologist. ...Read moreSee 1 more doctor answer
Not uncommon.: Sometimes a viral infection can trigger this...or it is possible to develop seasonal or other allergies, even if they weren't there when younger. There are other lung conditions that can mimic asthma, so just be sure you've discussed this with your doctor or a pulmonologist or allergist. ...Read moreSee 1 more doctor answer
