I woke up in a hot sweat with a stomach pain so I went to the toilet. After a few minutes I began to vomit repeatedly and got diarrhoea. I then began to heat up profoundly and started to shake. I tried to make my way to the shower and must have collapsed as I woke up about 30 mins later on the floor. I have had a similar experience once before about two years ago. It is also worth noting that I am on my period although I never usually have any problems with this and throughout today I have been sick and to the toilet numerous times.
Hello, Thanks for posting a query, I understand that your periods are going on right now, and you are having these sudden onset pain in abdomen with sweats and diarrhea and vomiting. The most common possibility is that you are having a gastroenteritis or a gastritis, and you are also having a low blood pressure cause of volume loss and that has led to your fainting spell.  You should immediately visit the ER and get your BP checked and if its low then some IV fluids should do good to you. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you. In future if you wish to contact me directly, you can use the below-mentioned link:bit.ly/ Chat Doctor.
