You should see a pulmonologist if you use your rescue inhaler more than twice a week, wake at night with asthma symptoms, have had one or more severe attacks in the past year, or your daily life is limited by breathlessness. At Pulmovista Clinics, Dr. Dixit Kumar Thakur provides specialist-level diagnosis and treatment that goes beyond what a general physician can offer — including spirometry, FeNO testing, allergy workup, and biologic therapy assessment.
