Acid reflux cough at night

The cough may occur with heartburn, a sour taste, hoarseness or frequent throat-clearing, but reflux can also cause cough without obvious burning. Reducing evening triggers and reviewing persistent symptoms with a clinician can help identify the right approach.

Lying flat removes some of gravity's help in keeping stomach contents down. Refluxate can irritate the lower oesophagus and activate a cough reflex; if it travels higher, it may irritate the voice box and throat. A late or large meal can make this pattern more noticeable.

Night coughing has other possible causes, including asthma, nasal drainage, infection and some medicines. Clues such as wheezing, blocked nose, fever, the timing of meals and how long the cough has lasted help a clinician separate these possibilities.

Leave a gap between the evening meal and lying down, choose a smaller dinner, and note whether fatty or spicy foods, caffeine or fizzy drinks trigger symptoms for you. Avoid tobacco smoke and limit alcohol if either worsens the cough.

Raise the head end of the bed or use a wedge that supports the upper body; stacking ordinary pillows may bend the abdomen and be less useful. If you use a reflux medicine, follow its directions because timing differs by product. Do not repeatedly add over-the-counter remedies without checking for interactions or reasons the cough continues.

Seek urgent help for severe or crushing chest pain, marked breathing difficulty, blue or grey lips, fainting, coughing up blood, vomit that contains blood, or black sticky stools. These signs should not be managed as simple reflux at home.

Arrange a clinical assessment if the cough keeps returning, disrupts sleep, lasts for several weeks, or comes with trouble swallowing, painful swallowing, unexplained weight loss, fever or persistent vomiting. Assessment may include a medicine review and checks for lung, nasal or digestive causes.

Ask whether your symptom pattern fits reflux or needs testing for asthma, nasal drainage or another cause. Confirm when to take any medicine, how long to try it, which side effects matter, and what change would mean you need follow-up.
