Acute gastroenteritis, as understood literally, occurs quite suddenly and rapidly. Therefore, its treatment is not very complicated. Typically, it can be cured in a short term. If it is a bacterial infection, you might choose Levofloxacin, which is quite effective in reducing intestinal inflammation. Generally, about three days of intravenous infusion can cure it. After stopping the infusion, you can take some probiotics orally and adjust the intestinal microenvironment, which can make recovery more thorough. So, if you suffer from acute gastroenteritis, there's no need to panic. As long as you maintain good dietary hygiene, you can recover quickly.
