It is a neuromuscular condition characterized by oesophageal aperistalsis and impaired relaxation of the lower oesophageal sphincter.
What other condition can mimic the symptoms of achalasia.
Chagas' disease. (Trypanosoma Cruz infection in South America).
What age group does achalasia tend to affect.
Typically affects those aged 25-60 years.

Regurgitation of food from the dilated oesophagus can lead to aspiration pneumonia.
What is the differential diagnosis for patients presenting with achalasia. (4)
Chronic inflammatory conditions.
What are the signs of achalasia. (3)
There are no physical signs, confirmation of diagnosis is by:
Barium swallow: shows tapering of the lower oesophagus (bird's beak), with proximal dilation.
Oesophageal nanometre: reveals incomplete relaxation of the lower oesophageal sphincter.
OGD: to exclude malignancy.
