People experiencing a persistent chesty cough that produces phlegm are advised to consult their GP as they might be among the 600,000 undiagnosed cases of a serious illness.
During late autumn, it is common to develop a cough, sore throat, or both due to increased indoor time leading to easier virus transmission. Typically, the cause is the common cold, with symptoms resolving within a few days.
However, a lingering chesty cough that continues to produce phlegm could indicate Chronic obstructive pulmonary disease (COPD), which, if untreated, can result in severe health issues like pulmonary hypertension, pneumonia, and heart disease.
Reportedly, in the UK, around 1.7 million individuals live with COPD, with approximately 600,000 undiagnosed cases, as per Asthma + Lung UK. Symptoms usually manifest around late 40s or 50s, although diagnosis can happen earlier, especially in current or former smokers.
According to the NHS, common COPD symptoms include breathlessness, persistent chesty cough, frequent chest infections, and wheezing.
Less common symptoms include weight loss, fatigue, swollen ankles due to fluid retention, chest pain, and coughing up blood. Symptoms may start mildly and worsen gradually over time, affecting breathing and daily activities in severe cases.
If experiencing persistent COPD symptoms, it is advisable to schedule a consultation with a GP for proper evaluation. Diagnosis often involves a chest examination, lung function tests using a spirometer, and treatment through inhalers, medications, and pulmonary rehabilitation programs.
Quitting smoking is the primary method to lower the risk of developing COPD. Even diagnosed individuals can witness substantial health improvements by ceasing smoking habits.
