Unhappy Do they really need blood tests? - July 21st 2012, 06:21 AM

So I am about 95 percent sure I have a hernia again. I can go see my doctor in three weeks, and then I have to get a hard thing on my hand removed as well. I can not do blood tests without passing out and vomiting, and I was wondering of blood tests before surgery are a 100 percent thing? Also does anyone know if this problem could be why I get nacious after eating or when I'm hungry?

The nausea could be caused by the hernia as it is not an uncommon symptom.

Yes, they have to do blood work before most surgeries. There are a plethora of reasons why, but as an example...If you have an unnaturally high red blood cell count, most surgeons will not put you under anesthesia, preventing them from doing the surgery. High red blood cells can mean there is an underlying cause, which could potentially be fatal to put you under anesthesia, or to perform surgery - depending on the cause.

Do you know why you get sick? Is it from seeing it? Feeling it? Or is it due to them actually taking blood? Have you tried eating something sugary and drinking LOTS of water before getting your blood drawn? Have you tried lying down while they take your blood?

Talk to the doctors about this so they can best help your experience with them. Maybe they can give you some medicine or just some other advice to try.

I am really scared of needles (like a lot of people I know) and everything from seeing it to feeling it makes me sick. Last time I got my finger pricked and last time I got a shot I passed out and had to lay down on a table for thirty minutes. The place where they draw blood is extremely sensitive, and no matter how much I try and man up, I can't even write on that part. When I try to tough it out, that's when I throw up and pass out.

Well, discuss this with the doctors or a secretary at the place where you will be getting your blood drawn. There are medications doctors can give you to help you not have such a severe reaction. They can also attempt to numb the area so you do not feel the needle prick.

Just talk with them and explain how severe it is.

Blood tests are required before and sometimes after surgeries. The purpose of them before surgeries is to determine whether it is safe to perform the surgery and whether there are any additional precautions. For example, a blood test can reveal your prothombin time, which represents the likelihood of your blood clotting on its own. Depending on the value, you may be given anti-coagulation medications. It is also possible to determine whether someone may have a particular coagulation disorder based on several measures, including prothrombin time, which is crucial to know when going in for a surgery.

Since your reaction is that intense, the doctor may recommend to try drawing blood from another place, although if that fails, you may be given a fast-acting sedative.
