What does intestinally mean?
Intestinally is an adverb meaning in, into, or through the intestines. It is used primarily in medical, pharmacological, and nutritional contexts to describe how a substance is administered, absorbed, transported, or otherwise processed within the intestinal tract. For example, a medicine described as being absorbed intestinally takes effect through the intestines rather than being introduced directly into the bloodstream. The term distinguishes the site or route of a process without necessarily implying that the substance is swallowed: administration into the intestine and passage through the intestines can both be described in this way. Although the word is readily understood by specialists, it is uncommon in everyday speech, where more general expressions such as “through the intestines” are often preferred.

Where does intestinally come from?
Intestinally was formed in English from the adjective intestinal and the adverbial suffix -ly. The adjective intestinal comes from Latin intestinalis, meaning “of or pertaining to the intestines,” which was derived from Latin intestinus, “internal” or “of the intestines.” English has long used intestine and intestinal, while related forms such as gastrointestinal combine the same Latin-derived element with another anatomical term.
How intestinally is actually used
This is a relatively uncommon technical term, found mainly in medicine, pharmacology, nutrition, and biological research. It describes an action or process involving the intestinal tract rather than the digestive tract as a whole.
