President Obama denies North Korea can make a nuclear strike against the U.S. or its allies, claiming they cannot make a nuclear weapon miniaturized (small and lightweight enough) for missile delivery. The miniaturization myth never made sense technically and is contradicted by the defense community.
Causes of Esophageal Strictures. Esophagitis is the inflammation of the lining of the esophagus which often leads to swelling. Some of the common causes include chronic acid reflux (GERD / gastroesophageal reflux disease), infections or autoimmune causes (eosinophilic esophagitis).
Definition. Esophageal stricture is when the esophagus narrows making it hard to swallow. The esophagus is a muscular tube that carries food and liquids from the mouth to the stomach. Esophageal stricture may cause large chunks of food to get stuck in the esophagus.
