Achalasia can be mistaken for reflux. Compare with acid reflux symptoms and causes.
What is achalasia?
Achalasia is an uncommon condition where the valve at the bottom of the oesophagus does not relax properly and the oesophagus does not squeeze normally. Food and liquid can build up in the oesophagus.
What are the symptoms?
Symptoms include difficulty swallowing both solids and liquids, regurgitation of undigested food, chest pain, coughing at night and weight loss. It is sometimes mistaken for reflux.
How is achalasia diagnosed and treated?
High-resolution oesophageal manometry is the key test, together with a gastroscopy and sometimes a timed barium swallow. Treatments include balloon dilatation, keyhole surgery (Heller myotomy) or an endoscopic procedure called POEM, which have similar success in experienced hands. Botulinum toxin injection gives shorter-term relief for people not suited to other options. The best choice depends on the type of achalasia and your overall health.
