Final answer:
The most common symptom of achalasia is difficulty swallowing, while the worst symptoms could include esophageal dilation and risk of aspiration leading to respiratory problems.
Step-by-step explanation:
What is the most common s/s of achalasia? The most common symptom (s/s) of achalasia is difficulty swallowing (dysphagia), which can affect both solids and liquids. This occurs due to the inability of the lower esophageal sphincter (LES) to relax properly. Other common symptoms include regurgitation of food, chest pain, and weight loss.
What is the worst s/s of achalasia? The worst symptom of achalasia may vary between patients, but esophageal dilation and the risk of aspiration are serious complications that can arise. Over time, the esophagus may become significantly dilated, and the retained food can lead to aspiration, which is the breathing in of food particles into the lungs, potentially causing pneumonia or other respiratory issues.
