You're coughing a lot but not feeling sick due to common culprits like postnasal drip (mucus from sinuses), acid reflux (GERD), or asthma, which irritate your throat and airways without typical sickness signs like fever. Other causes include allergies, inhaled irritants (dust, smoke, strong smells), certain medications (ACE inhibitors), or even a habit cough after an infection.
Lingering coughs are often due to an unresolved infection, virus or flare-up of an underlying health condition—such as lung disease or asthma—whereas a chronic cough can be a sign of asthma, COPD, acid reflux, gastroesophageal reflux disease (GERD) or upper airway cough syndrome.
The most common causes are tobacco use and asthma. Other common causes include fluid that drips from the nose down the back of the throat, called postnasal drip, and the backward flow of stomach acid into the tube that connects the throat to the stomach, called acid reflux.
Lifestyle and home remedies
Pediatric chronic cough can occur due to infection, respiratory disease or environmental exposure to various pollutants. Symptoms can include a dry cough, hoarse cough, or productive cough with mucus.
Consult your doctor if your cough lasts longer than a week or is accompanied by:
Respiratory tract infections (RTIs)
Additionally, foods high in citric acid (like lemons and limes), as well as acetic acid (found in things like vinegar or pickled vegetables), have also been proven to tickle our cough centers. Though giving up your favorite foods is never fun, paying attention to your diet can help eliminate your post-meal cough.
Often, the cause of a persistent cough is unknown (idiopathic). Rarely, a persistent cough can be a symptom of a more serious condition, such as lung cancer, heart failure, a pulmonary embolism (blood clot on the lung) or tuberculosis.
Some signs that you may need to go to urgent care with your cough include:
When the heart's not pumping properly, fluid can build up in the lungs, which can cause a cough and sometimes shortness of breath. A cough from heart failure tends to be persistent and you might produce phlegm, which can be white, pink or blood-tinged.
PURPOSE: Vitamin B12 deficiency causes sensory neuropathy, that might contribute to the pathogenesis of chronic cough and pharyngo-laryngeal dysfunction. Increased nerve growth factor (NGF) levels have been demonstrated in cobalamin deficiency.
Often dry and persistent – Unlike productive coughs associated with infections, anxiety coughs are usually non-productive. Accompanied by other anxiety symptoms – Shortness of breath, tight chest, lump-in-throat sensation. No underlying respiratory infection – No fever, congestion, or other signs of illness.
A cough is your body's response when something irritates your throat or airways. An irritant stimulates nerves that send a message to your brain. The brain then tells muscles in your chest and abdomen to push air out of your lungs to force out the irritant.
When should chronic cough be treated by a doctor or healthcare provider? If your cough lasts 10 days or more, and you don't know why, it's time to see your provider. If you have more serious symptoms, let your provider know right away or seek urgent medical care.
Signs and symptoms:
Particularly in the context of the above risk factors and cough, associated red flag symptoms and signs for significant disease include: Weight loss. New coughs lasting over three weeks. Unexplained haemoptysis, particularly if recurrent or persisting. Breathlessness.
The four main types of coughs are: wet, dry, paroxysmal and croup. Most coughs do go away on their own. Home remedies and over-the-counter cough medicines can help relieve symptoms.
The signs and symptoms of pneumonia may include: Cough, which may produce greenish, yellow or even bloody mucus.
Reducing throat irritation: Selecting appropriate foods and preparation methods can minimize throat irritation, reducing itchiness and the likelihood of frequent coughing. To achieve this, avoid irritating foods like sour, spicy, salty, or hot dishes.
To make yourself as comfortable as possible when you have a cough or cold, try to: Drink plenty of fluids. Stay hydrated with water, juice, clear broth or warm lemon water with honey. Avoid caffeine and alcohol, which can dehydrate you.
Processed meats with nitrates, dairy that thickens mucus, and high-sulphite options like dried fruit and wine all contribute to irritating lungs. If you're sensitive, spicy foods can easily lead to coughing fits. Opting for fresh, whole foods and staying hydrated can help support lung health.
Lung infection symptoms
Chest pain when breathing deeply or coughing. Mucus (phlegm) that is greenish, yellow, or bloody. Fever, chills, and sweating.
The common cold, the flu, RSV, and COVID-19 are viral respiratory infections that spread easily during certain seasons.
While viral and bacterial infections can share similar symptoms, there are key differences. Viral infections often develop gradually, such as a cold that starts with a scratchy throat and progresses to a cough and congestion. Bacterial infections, however, tend to appear suddenly and with more intensity.
