###Human: Will diarrhea cause fluid and electrolyte imbalance and fatigue? ###Assistant: Hi. You have lost quite a bit of fluid. You need to get rehydrated again. If your loose motion has not stopped, you need to take tablet Loperamide once, and you need IV saline to bring your BP up. It is better to get to the ER and get the IV saline first. Please go to the hospital now or ask someone to come over to your place to give you the IV saline. If you have a vomiting, do not eat anything as this will cause more vomiting and you will lose more fluid and electrolytes.
