What Is Overlap Syndrome?
Asthma-COPD syndrome overlap happens when an individual presents characteristics of chronic obstructive pulmonary disease and asthma. The combination of these may result in more serious respiratory symptoms and increased risk of exacerbation.
Common Causes and Risk Factors
Long-term exposure to cigarette smoke or air pollution
History of asthma or allergies in childhood
Frequent lung infections
Family history of chronic lung disease
Workplace exposure to dust, chemicals, or fumes
Age over 40 with a history of smoking
Signs and Symptoms
Shortness of breath, especially during activity
Wheezing or noisy breathing
Persistent cough with or without mucus
Chest tightness or discomfort
Frequent respiratory flare-ups or exacerbations
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He examines your history of asthma exacerbations, the symptoms of COPD, whether you smoke or not, what you are allergic to, whether exposed to occupations or the environment, and your family history of lung-related diseases.
Spirometry with Bronchodilator Challenge
Spirometry can gauge the amount of air that you can inhale and also the amount of air that you can exhale. Whether or not your airway obstruction will resolve to a repeat test after the administration of a bronchodilator is a factor of whether your feature reflects asthma or COPD.
Blood Tests
To determine allergic inflammation, he measures the level of eosinophils in blood and IgE. Measurement of alpha-1 antitrypsin levels is done in selected patients in case early or suspected atypical COPD is suspected.
Imaging Studies
Chest X-ray to exclude infections, tumors, or other lung conditions.
High-resolution CT scan to evaluate airway wall thickening, emphysema, and overall lung architecture.
Advanced Pulmonary Testing (If Needed)
In complicated cases, lung volume testing, diffusion capacity (DLCO) tests or bronchial provocation (methacholine challenge) can be conducted to narrow the overlap syndrome diagnosis.

Frequently Asked Questions
What is asthma-COPD overlap syndrome?
It is when an individual possesses the features of asthma and COPD. The overlap usually leads to the more severe breathing issues, unless handled well.
Does it influence the lifespan of my life?
Most of us are able to live well and have full active lives with early care and following up on treatment plan. It is important to prevent the flare-ups and adhere to the instructions provided by Dr. Scott.
What diagnosis code is used?
When entering the information regarding the overlap syndrome, doctors frequently use codes J45 of asthma and J44.9 of COPD.
Is the pulmonary damage reversible?
Permanent scarring is irreversible, but it can be treated with significant benefits to the functioning of the lungs, decrease symptoms, and increase the quality of life.
What is the frequency of Dr. Scott visitation?
Periodical visits are normally 3-6 months. The follow-ups might have to be increased during flare-ups or during changes of medication.
Should vaccines be considered necessary?
Yes. The immune systems against the flu and pneumonia are also inoculated annually to prevent severe lung infection and minimise the exposure to severe exacerbations.
Will I need oxygen?
There are patients that need oxygen supplementation either when sleeping or when performing an activity. Dr. Scott will also examine your oxygen levels and then he will make any recommendations.
