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.
An esophageal stricture is a gradual narrowing of the esophagus, which can lead to swallowing difficulties. The strictures are caused by scar tissue that builds up in the esophagus. When the lining of the esophagus is damaged, scarring develops. When scarring occurs, the lining of the esophagus becomes stiff.
