Respiratory disease: clear, practical help for everyday problems

A cough, shortness of breath, or chest tightness can feel scary. Respiratory disease covers everything from short-lived infections to long-term conditions like asthma, COPD, and pulmonary hypertension. This page helps you spot warning signs, understand common treatments, and pick useful next steps without medical jargon.

Common causes and symptoms

Respiratory problems come from infections (cold, flu, pneumonia), allergies, smoking, workplace exposures, or chronic illnesses like asthma and COPD. Watch for these signs: persistent cough lasting weeks, wheezing, breathlessness during everyday activities, chest pain when breathing, or coughing up blood. A fever and sudden worsening of symptoms usually point to an infection and mean you should seek care fast.

Not all breathlessness is the same. If it comes on suddenly, gets worse quickly, or you can’t speak in full sentences, treat it as an emergency. If symptoms are milder but interfere with sleep or work, make an appointment with your primary care provider or a lung specialist.

What to do and treatment options

First step: figure out if the issue is short-term or chronic. For infections, doctors often recommend rest, fluids, and sometimes antibiotics. For resistant or severe bacterial infections, medications like linezolid (Zyvox) may be used under strict medical supervision. For chronic conditions, inhalers are the main tool—bronchodilators open airways, and inhaled steroids reduce inflammation. Over-the-counter epinephrine inhalers like Primatene Mist exist, but check current FDA guidance and talk with your clinician before using them as a substitute for prescribed asthma inhalers.

Pulmonary arterial hypertension (PAH) is less common but serious. Drugs such as ambrisentan help reduce pressure in lung blood vessels and improve symptoms, though they need specialist oversight and regular monitoring. Oxygen therapy, pulmonary rehab, and lifestyle changes—quit smoking, avoid pollutants, stay active—also make a big difference for many people.

Preventive steps matter: get annual flu shots, stay current on pneumonia vaccines if you’re in a risk group, manage allergies, and avoid indoor smoke. For long-term care, build a simple action plan with your provider: which inhaler to use first, when to add a rescue dose, and when to call for help.
