Hello!! Whenever you are sick or having diarrhea, sometimes you will get cold sweats. The cold sweats will allow your body to try to maintain homeostasis and bring your temperature down, if you are sick and have a virus. If you have diarrhea from bad food or something to that nature, you will start to go through the dehydration process. Whenever you lose that amount of liquid in your body, you will need to put water back into your system so your body can work properly. If you do not drink lots of water whenever you have diarrhea, you will feel dizzy, have muscle cramps, or feel like you are going to pass out. Your body’s way of maintaining homeostasis when having diarrhea is by replenishing the water you put back in, and putting it to good use for the present tense. I hope this has helped you!! Have a great night.
