Stainless Steel and the passive layer Steel is an alloy of iron and carbon. Contrary to carbon steel, the presence of a minimum of 10.5 % chromium in the stainless steel gives it the property of corrosion resistance. Indeed, on contact with oxygen, a chromium oxide layer is formed on the surface of the material.
Sinus Drainage & Stomach Problems. One of the primary results of sinus congestion is drainage. Sinus drainage is expelled in two basic ways: through the nose and the back of the throat. When sinus drainage is expelled in back of the throat, it is referred to as postnasal drip and can cause stomach discomfort.
GERD Leads to Mucous Production in the Throat. Stomach contents are acidic in nature. Our esophagus is not prepared to handle it and gets corroded. The acid irritates the throat. In response, the mucosal lining of the throat produces thick, sticky mucous. The patient feels as if something is constantly sticking in the throat. This phlegm may cause chronic cough in a long run. You may visit a doctor and get evaluated.
