Achalasia is a rare digestive disorder characterized by the inability of the muscles at the lower end of the esophagus to relax properly, leading to symptoms such as difficulty swallowing and chest pain.

Diagnosis is made through endoscopy, barium swallow imaging, and esophageal manometry. Treatment options include balloon dilation, botulinum toxin (Botox) injections, or surgical intervention.

With modern surgical techniques such as laparoscopic Heller myotomy, patients can experience a significant improvement in eating comfort and quality of life.
