Persistent cough. When a chest X-ray is needed

Coughing is a natural reflex of the body, but when it persists for more than three weeks, it can be a sign of a serious condition. Pulmonologists point out that a prolonged cough can indicate serious lung problems, from chronic infections to lung cancer.

In the cold season, this symptom is often ignored, but specialists emphasize the importance of quick investigations for a correct diagnosis.

When the cough becomes a cause for concern

Although colds and flu are the most common causes of cough, a cough that lasts more than three weeks should be investigated. Dr. Magdalena Ciobanu, pulmonologist, warns: “It is good to have a chest X-ray if you notice symptoms such as bloody sputum, chest pain, repeated pneumonia or bronchitis, unexplained fatigue, weight loss or persistent hoarseness.”

These symptoms can indicate more serious problems, including chronic infections, asthma or even lung cancer.

Common causes of chronic cough

1. Prolonged viral infections: Flus and colds can leave a persistent cough even after the infection clears.
2. Bronchial asthma: It is characterized by a dry cough, frequent during the night or triggered by physical exertion and cold air.
3. Gastroesophageal reflux: Stomach acid rising into the esophagus can irritate the airways, triggering coughing.
4. Chronic sinusitis: Sinus inflammation can cause secretions to drain into the throat, causing coughing.
5. Allergic factors: Dust, pollen or pets can make coughing worse in sensitive people.

In children, chronic cough can have various causes, from asthma and gastroesophageal reflux to sinusitis or, less commonly, aspirated foreign bodies.

Cough and lung cancer

One of the most alarming causes of chronic cough is lung cancer. Doctors recommend a lung x-ray if the cough is accompanied by other symptoms such as:

• He spits blood
• Unexplained weight loss
• Chronic fatigue
• Chest pain
• Recurrent pneumonia or bronchitis

A chest X-ray is a first step in diagnosis, but further investigations such as computed tomography or biopsy may be necessary for confirmation.

How to manage cough at home

For coughs caused by viral infections or allergies, the following methods may be helpful:

• Hot liquids: Lemon or orange teas and warm soups help keep you hydrated and soothe your throat.
• Physiological serum: Nasal instillations can help reduce irritation.
• Cough syrups: Choose products specific to the type of cough – dry or productive – according to the doctor’s recommendations.
• Avoiding irritants: Cigarette smoke, pollution or dry air can make symptoms worse.

If the cough does not improve within three weeks or is accompanied by serious symptoms, it is essential to consult a specialist. A quick diagnosis can prevent complications and identify serious conditions in the early stages.
