HI, thanks for using healthcare magic Acute diarrhea is most commonly due to infection of the gastrointestinal tract by a virus or bacteria. Since the symptoms are severe, you may want to consider visiting your doctor for an assessment which would include sending a stool sample to the lab and possible blood test. In general , treatment involves the following: (1)hold off solid food for now (2)need to treat or prevent dehydration by the use of fluids. Use oral rehydration fluids or gatorade (3)probiotics would also help . They can be used on their own or in some yogurts (4)there are agents that would slow down the diarrhea that you can obtain from your local pharmacy. I hope this helps
