What does diuretically mean?
"Diuretically" is an adverb describing something that acts so as to increase the production and excretion of urine — in other words, in the manner of a diuretic. It derives from "diuretic," an adjective and noun used in medicine for substances that promote urination, which in turn comes from the Greek "ourein," meaning "to urinate." The word appears almost entirely in medical, pharmacological, and scientific contexts: clinicians might say that a drug works diuretically to relieve fluid retention, or that certain foods, such as asparagus or caffeinated beverages, behave diuretically. Because it belongs to a specialized register, it is uncommon in casual conversation, where speakers are more likely to say a substance "makes you pee more" or is a "water pill." Still, it fills a precise descriptive niche for writers who need an exact, single-word way to characterize this physiological effect.

Etymology of diuretically
"Diuretically" is formed by adding the adverbial suffix "-ally" to "diuretic," which entered English in the late eighteenth century. "Diuretic" comes from the French "diurétique" and ultimately from the Greek "diouretikos," derived from "diourein" ("to urinate"), a compound of "dia-" ("through") and "ourein" ("to urinate"). The same Greek root gives us "diuresis" (increased urine production) and underlies words built on "ouron" (urine), such as "urology" and "urea."
