Question: My husband (70) woke up at 6:00 this morning, he had diarrhea, vomiting. I heard him fall so ran to check on him. He had passed out on the floor, I got him to come around and he still had to vomit. He's in bed now
. Can not seem to get warm. Still trying to vomit some but of course his stomach is empty. I am not sure what to do. I asked him if he wanted to drink something, he thought maybe in a little while

Please follow the detailed answer.

Detailed Answer:
Thanks for the query dear,
Have gone through your details and I appreciate your concerns.

Most likely he is having gastroenteritis usually gastroenteritis is by viral infection(Nova virus) and is self-limiting. Takes five to seven days. However, in some cases, it is either bacterial or protozoal infection or a mixed infection.

Vomiting and diarrhea cause body to lose important electrolytes like sodium and potassium. Secondly, loss of a large amount of water causes dehydration which results in the decrease in blood pressure causing dizziness or presyncope.

The function of blood is to maintain body warmth. Blood consists of 70% water. Now due to dehydration blood volume decreases hence unable to maintain the warm temperature.

I would suggest you to the nearest emergency room and get his blood pressure, pulse, hydration level, and serum electrolytes level checked promptly.

Few tests to be done after that are-
Ultrasound abdomen
Stool microscopy analysis
Complete blood count
Total and differential leucocyte count.
Intravenous fluid would also need to be administered along with antidiarrhoeals like Imodium and antiemetic like Zofran.

Feel free to ask further.

Thanks and Regards!

Hi my is Angi. So I went to the bathroom and I notice my feces was weird looking. It was white at the very tip and with a bit of blood. I've had anal sex probably 2 weeks before this happened but I've also done this before and nothing was abnormal. Im just wondering what it could possibly be. Im too embarrassed to go to a doctor.
I hope to hear back from you. Thanks.

Having irregular bowel movement. Somtimes it takes place 8 times a day. Normally for the first time the stool is normal but afterwards it becomes liquid in nature and also its volume reduces. Sometimes in the morning itself I have to go three times in short span. During such time normally I pass too much gas
