What is Dysphagia? Definition, Causes, & Pitfalls

In this lecture from This is Why, Dr. Busti will break down dysphagia—the medical term for difficulty swallowing—in a clear, clinically relevant way. You’ll learn what dysphagia means, how clinicians use the term, and how to quickly recognize the difference between oropharyngeal dysphagia vs esophageal dysphagia. We’ll also cover high-yield dysphagia causes, red flags, and common pitfalls that lead to missed diagnoses—especially when aspiration risk is overlooked.

What you’ll learn (quick + practical):

- Dysphagia definition and how it shows up in real patients (“trouble swallowing)

- Oropharyngeal vs esophageal dysphagia: symptom patterns that matter

- Common causes: stroke dysphagia, Parkinson disease, dementia, neurologic/neuromuscular conditions, GERD, strictures/rings, eosinophilic esophagitis, and achalasia

- Complications: aspiration, aspiration pneumonia, dehydration, malnutrition, food impaction

- Evaluation basics: bedside swallow assessment, swallow evaluation, modified barium swallow / VFSS, FEES, barium swallow, and upper endoscopy (EGD)

The goal = make medical education easy and clinically relevant.
