Bettas being kept as pets will do well on a standard pellet food designed especially for bettas (I recommend HBH Betta Bites or Tetramin granules) with an occasional treat of frozen/live worms or freeze-dried brine shrimp andbloodworms. Pet bettas should not be overfed; a few pellets per feeding is sufficient.
Upper Gastrointestinal Endoscopy. Guide. An upper gastrointestinal (UGI) endoscopy is a procedure that allows your doctor to look at the inside lining of your esophagus , your stomach, and the first part of your small intestine (duodenum ). A thin, flexible viewing tool called an endoscope (scope) is used.
Key Points. 1  All patients complaining of esophageal dysphagia should undergo upper endoscopy to rule out cancer. 2  If the upper endoscopy is normal, biopsies should be obtained to rule out eosinophilic esophagitis. 3  Treatment of dysphagia is geared toward the cause.
