Chronic Cough Evaluation in Southern Highlands, NV
Find the root cause of your chronic cough with expert testing and care.
A chronic cough that lingers for more than eight weeks is not something to shrug off, and it often has a treatable cause that a general practitioner may not have the tools to identify. Allergic rhinitis with postnasal drip, undiagnosed asthma, non-allergic rhinitis, and reactive airway disease all commonly present as a persistent cough in Southern Highlands adults and children. Tottori Allergy and Asthma Associates has been serving Las Vegas since 1992 and provides the specific testing, including spirometry and allergy evaluation, that turns a mystery cough into a clear diagnosis.
Dr. David H. Tottori is board certified in Allergy and Immunology plus Pediatrics, so both children and adults with chronic cough get evaluated by a specialist who understands the many conditions that share this symptom. Our East office on Charleston Boulevard is reachable from Southern Highlands via the 215 Beltway or I-15. Call 702.432.8250 or request an appointment online to start finding the root cause.
What Actually Causes a Chronic Cough
A chronic cough is defined as one that lasts more than eight weeks in adults, or more than four weeks in children. The reason it lingers is that the underlying trigger keeps stimulating the cough reflex, either from irritation in the airways, drainage from the sinuses, or acid reaching the throat from below. Identifying the trigger is the whole game, because targeted treatment resolves the cough while non-targeted treatment often does not.
The most common causes in the Las Vegas Valley are upper airway cough syndrome, which is the current medical term for postnasal drip from allergic or non-allergic rhinitis, cough variant asthma where cough is the main asthma symptom without obvious wheezing, and gastroesophageal reflux disease. Less common but important causes include eosinophilic bronchitis, medications like ACE inhibitors, and rare structural airway problems. Chronic Cough is listed among the lung conditions in the Tottori conditions we treat list precisely because so many chronic coughs are driven by allergic or asthmatic mechanisms an allergist is trained to identify.
Environmental factors specific to Southern Nevada matter too. Desert dust, high pollen days from mesquite and mulberry trees, wildfire smoke drifting in from California, and Bermuda grass allergens can all sustain a cough well after a viral illness has resolved.
Services That Diagnose Chronic Cough Causes
A thorough chronic cough workup often uses several diagnostics in combination:
- Pulmonary function testing with spirometry measures airway obstruction and its reversibility, key to identifying asthma or cough variant asthma.
- Allergy skin testing identifies environmental allergens driving postnasal drip and airway inflammation.
- Immunotherapy allergy shots can address the underlying allergic mechanism when confirmed allergens are the cough trigger.
- The complete range of services shows how testing, medication management, and immunotherapy fit together.
- A review of related conditions we treat helps put chronic cough in the context of related lung, nasal, and sinus problems.

Why Choose Tottori Allergy for Chronic Cough
A chronic cough often gets a prescription cough syrup and a shrug at a general clinic, which leaves patients cycling through months of unresolved symptoms. Tottori Allergy runs the specific tests that separate cough variant asthma, postnasal drip from allergic rhinitis, and non-allergic airway inflammation from one another, so the treatment plan matches the actual driver. That precision comes from more than 30 years of experience diagnosing lower and upper airway conditions.
The East office on Charleston is convenient for Southern Highlands residents driving up the 215 or I-15, and multilingual staff support in Spanish, Tagalog, and Mandarin makes the diagnostic conversation easier for patients whose first language is not English. Dr. Tottori has been named a Las Vegas Top Doctor every year since 2000, a recognition that reflects consistent outcomes across the practice.
