Title: Understanding Achalasia

Achalasia is a rare condition that affects the smooth muscle of the oesophagus, causing difficulty swallowing. It is often characterized by a sensation of fullness in the chest, difficulty swallowing, and regurgitation of food. If left untreated, it can lead to weight loss, malnutrition, and other serious complications.

Treatment for achalasia usually involves surgery, although there are also medications and dietary modifications that can be used as first-line treatment options. Understanding the condition and seeking appropriate treatment early can greatly improve the quality of life for those affected by it.
