A patient presents with dysphagia and weight loss. What is the most likely diagnosis?

• A. Esophageal cancer
• B. Gastroesophageal reflux disease
• C. Achalasia
• D. Candidiasis

Answer: (A)

The presentation of dysphagia (difficulty swallowing) along with significant weight loss raises concerns for serious underlying conditions, particularly those affecting the esophagus. In this scenario, esophageal cancer is the most likely diagnosis.

Esophageal cancer typically manifests with progressive dysphagia, often starting with solids and advancing to liquids as the condition worsens. The connection to weight loss is significant, as patients often modify their diets, avoiding difficult-to-swallow foods, resulting in unintentional weight loss. Additionally, esophageal malignancies can present with other symptoms such as odynophagia (painful swallowing), persistent cough, or even hematemesis in advanced cases, contributing further to a decline in nutritional intake and weight status.

While other conditions such as gastroesophageal reflux disease (GERD), achalasia, and candidiasis can also cause dysphagia, they usually do not present with the same rapid and significant weight loss when compared to cancer. GERD typically presents with heartburn and may lead to some discomfort swallowing rather than severe dysphagia and weight loss. Achalasia is characterized by a lack of peristalsis in the esophagus and can cause dysphagia, but the weight loss is generally not as pronounced unless the condition is
