The chronic, potentially dangerous condition known as acid reflux—also called GERD, or Gastroesophageal Reflux Disease—is hard to miss or ignore. One variety, however, often goes undetected. This program examines nocturnal GERD, which produces no daytime symptoms and may be tied to other sleep disorders. Outlining the factors that contribute to nocturnal GERD, including a high-fat diet and obesity, the program describes its warning signs, shows how physicians diagnose it, and presents a helpful case study. Expertise comes from Dr. Adam Elfant of Cooper University Hospital, Dr. Joseph Pisegna of the UCLA David Geffen School of Medicine, and Dr. Lee Hixson of Mountain West Gastroenterology. (26 minutes)
