Since the initial description, several studies have attempted to explore initiating agents that may cause the disease, such as viral infection, other environmental factors, autoimmunity, and genetic factors.
Cytokine-induced alterations of gastrointestinal motility in gastrointestinal disorders. These medications carry significant side effects and poor symptom relief.
The disease has been reported in monozygotic twins[ 42 ] and siblings[ 43 – 45 ]. Diagnosis is reached with esophageal manometry and barium swallow radiographic studies. It affects both sexes and all age groups[ 12 ]. This reduction in LES pressure leads to improved esophageal emptying and symptom relief. Long-term follow-up after pneumatic dilation for achalasia cardia: There is acute tapering achakasia the lower esophageal sphincter and narrowing at the gastro-esophageal junctionproducing a “bird’s beak” or “rat’s tail” appearance.
