COPD is a long-term lung condition that makes it hard to breathe. It includes diseases like emphysema and chronic bronchitis. People with COPD may have shortness of breath, persistent coughing, wheezing, and low energy, especially during physical activity.
Chronic sinusitis is a long-term inflammation of the sinuses that lasts for 12 weeks or longer, even with treatment. It can cause nasal congestion, facial pain or pressure, headaches, a sore throat, fatigue, and a reduced sense of smell or taste.
Severe allergies can trigger life-threatening reactions known as anaphylaxis. Common allergens include foods (e.g., nuts, shellfish), insect stings, medications, and latex. Symptoms can escalate rapidly, causing breathing difficulties, swelling, low blood pressure, and loss of consciousness.
Severe asthma is a form of asthma that remains uncontrolled despite high-dose inhaled corticosteroids and other treatments. It causes frequent wheezing, shortness of breath, chest tightness, and coughing, which can be life-threatening if a severe attack occurs.
