What is hyster?

Answer 1

Hyperventilation Syndrome is almost always a disease of young adults. Hyperventilation syndrome (HVS) is an episodic disorder that often presents with chest pain and a tingling sensation of the fingertips (paresthesia) and around the mouth, as well as deep and labored breathing (causing hyperventilation), although chronic but subtle hyperventilation can cause these symptoms too. Hyperventilation is breathing in excess of what the body needs. This is sometimes called overbreathing. Rapid or deep breathing is sometimes seen in very serious conditions such as infection, bleeding, or heart attack.
