Undigestion

The presence of food in any state of digestion or undigestion in the ileum must be a source of irritation and danger.

A new word was introduced recently into English — undigestion. This simply refers to a lack of movement of food in the stomach and small intestine and responds to treatment with domperidone.

When we arrived at one of those soda ponds, being a little backwash slough with a white deposit over the top, I collected a pocketful of dust that goes by the western name of “saleratus,” which is practically the identical same thing as baking soda, and really first-rate for undigestion.
