Patients who have trouble swallowing and an impaired coughing mechanism (dysphagia) are at risk for food and liquids getting into their lungs, which can result in pneumonia. Because of this, patients with dysphagia are often prescribed special diets. Pureed food is pretty obvious, but how about thick water? Thickening agents are often added to fluids to reduce the chance of it getting into the lungs.

There's also honey thick and pudding thick. My instructor brought some Thick N Easy for my class to try. Suffice to say, thick water is weird and thick Diet Coke is vile.
