All ‘red flag’ warning signs that suggest you have lung damage
Your lungs may show external warning signs when something is wrong internally. Experts from **Respiratory Therapy Zone (RTZ)** highlight 13 key symptoms to watch for, including **finger clubbing** (swollen fingertips from low oxygen), a **chronic cough** lasting over eight weeks, **shortness of breath**, and **wheezing** (a whistling sound while breathing). Other red flags are **blue lips or fingertips** (cyanosis), **coughing up blood**, **chronic chest pain**, and **excessive mucus production** for more than three months. These could indicate serious conditions like asthma, COPD, or even lung cancer.
Additional signs include **frequent respiratory infections**, **chest tightness**, **unexplained weight loss**, **chronic fatigue**, and **swelling in the legs or feet** due to fluid buildup. RTZ emphasizes that even non-smokers can develop lung issues from pollution, infections, or chemical exposure. If you experience any of these symptoms, especially **coughing up blood** or **severe breathing difficulties**, seek medical attention immediately to prevent long-term damage. Early detection can make a significant difference in treatment and recovery.
