Dehydration Test for Food Poisoning

Video Transcript

Hello my name is Dr. Susan Jewell and on behalf of expert village today, I'm going to talk to you about and how to recognize and how to reduce the risk of food poisoning. Now, in this clip I'm going to show you a particular common test that doctor's do, that you can actually perform yourself, to show signs of dehydration. Because, most patients that have food poisoning are usually very dehydrated from the vomiting and the diarrhea. So, it's very important that when you actually have food poisoning, that you take a lot of fluid intake, lots of water. But, here's how you can do a self dehydration test. So, here's my hand here, and you can see on here, on the skin, what you can do is with you index finger and your thumb, you can press, pinch a bit of the skin on top of your hand. You can do this anywhere on your body, that's got, you can do it on your elbows, elbows and palms, but the palms is the best. So you just use your index finger and your thumb and you just press, pinch your skin, pinch it and count to about three seconds and you let go. Now, when a person's, normal person is not dehydrated, well-hydrated the skin actually goes back into place, but, into its normal position. Now, a person that's very dehydrated, when you do the pinching of the skin like this, after three seconds, if you let go, the pinched skin actually stays pinched, it doesn't go back into shape. So, that's a sign of dehydration. The longer that it takes for the skin to go back into position the more dehydrated that person is.
