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.

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).
Causes of reflux-induced dysphagia usually relate to damage of the esophagus. Chronic reflux of stomach acids into your esophagus can irritate your throat and sometimes cause permanent impairment, according to the Mayo Clinic. Scar tissue can develop in your esophagus, which may also create a narrowing of the structure.
