Respiratory Allergy Symptoms: Cough, Wheeze, Tightness

Respiratory allergy symptoms are a cough that is worst at night, wheezing, chest tightness and shortness of breath that comes in episodes rather than steadily. ACAAI describes this set as allergic asthma, triggered by pollen, dust mites, pet dander and mold. The distinguishing feature is not severity but pattern: symptoms track an exposure and ease when it stops.

What happens in the airway

Inhaled allergen meets sensitized immune cells lining the bronchi. The mediators they release do three things at once — the muscle band around the airway contracts, the lining swells, and mucus production climbs. The tube narrows from every direction, and air moves out through it with more difficulty than it moved in. That is where the whistle on exhalation comes from, and why the sensation is described as tightness rather than pain.

What it feels like

• Cough, especially at night, on exertion, or when laughing
• Wheezing, the whistling sound heard on breathing out
• Chest tightness, a band rather than a stab
• Shortness of breath, from barely noticeable to frightening
• Running out of air sooner than expected during ordinary activity

MedlinePlus notes these range from mild to severe and may be daily or intermittent. Intensity varies between episodes in the same person, which is why one mild flare says nothing about the next.

Triggers worth mapping

ACAAI separates the allergens from the amplifiers. Grass, tree and weed pollen, pet dander, dust mites and mold are the allergic triggers. Viral respiratory infections, exercise, air irritants, stress, certain medicines, some food additives and weather changes intensify a reaction already primed. MedlinePlus adds cold air, household chemicals, outdoor air pollution and tobacco smoke.

Mapping your own list is the part that changes outcomes, because it converts a vague “bad week” into a specific bedroom, season or animal.

Adults and children

In adults the complaint is usually breathlessness or a cough that has outstayed an illness — a distinction worth reading against persistent cough causes. In children the signs are often quieter than the diagnosis suggests: fast breathing, a cough at 3 a.m., unusual fatigue during play, or sitting out of games without saying why. MedlinePlus notes asthma often starts during childhood and is more common in boys during those years.

When it becomes an emergency

Get emergency care if breathlessness is severe and rescue medication does not work, if the person cannot finish a sentence in one breath, if lips, face or nails look blue or gray, or if there is unusual drowsiness or confusion. MedlinePlus is explicit that a severe attack unresponsive to short-term relief medicines needs emergency care.
