Spasmodic croup is the ordinary croup, in which the spasm affects the muscles of the larynx and makes breathing difficult, causing a wheezing sound at each respiration. The disease seldom affects any but children, although hysterical persons and grown-up people having a catarrhal inflammation of the mucous membrane, are sometimes subject to it. It is said to be an ailment of the nerves, and is entirely reflex, so that the real trouble is to be found elsewhere, and most likely deranged digestion.

Causes

Over-feeding, improper food, constipation, colds and teething. (See infant feeding and dietaries for children.)
