Gradually means slowly, by small steps over time. Gradually improved, gradually got worse, gradually at first.
It is one of the commonest adverbs in English and is used constantly in medicine, weather and description of change. Gradually, then suddenly is the well-known formula for how things go bankrupt and how people fall in love, from Hemingway. Note gradual; and that gradually properly implies steps rather than merely slowness.
