That's normal, I feel the same! When I go for a blood test I can't see when the nurse is taking some blood from me it just makes me really sick.

Give us a little more info,but it sounds like you are dehydrated. Being dehydrated can feel awful. You feel like you want to vomit,dizziness, etc. Try to get to some asperine(2) and something to drink. The asperine will increase your blood flow slightly  and then you will be rehydrating. Try to consume some form of potassium and sodium. Like ceral or a banana with pb. If you are really dehydrated you won't feel normal for about 2-3 days. I had to give blood once to save a friend and I had just come back from running, and dude I passed out and sh8#%ed in my pants. I woke up and hurled, and I felt like crap for about 3 days. So i hope ya feel better.

it depends on the situation.  if someone has a slow GI bleed, they can be asymptomatic and have hemoglobins as low as 5 or 6.  However if someone is acutely bleeding, a drop from 14 to 10 may cause dizziness and hypotension.  The biggest factor is if their heart rate is elevated, their blood pressure drops and they feel weak and/or dizzy.

That's not a normal thing, you shouldn't be getting dizzy like that!  I highly doubt it is cancer, it's more likely blood pressure related, has the doctor checked that out?  Also ear problems are big problems in making people dizzy, fluid in the middle or inner ear, Menierres not sure how to spell that, can make you have dizzy attacks as well.  Do you have sinus problems or allergies?  do you swim much?  You need to go back to the doctor or find another one that will listen to you, and check things out but you'd have much more symptoms than dizzyness from cancer.  I have a friend who's hubby has lung and brain cancer.  He has times when he can move because his head hurts so bad, blurred vision, nausea, light hurts his eyes, and so on.

could be signs of dehydration, especially if the dizziness occurs when you stand up rapidly or stand up after being in a crouching position. do an experiment where you make a conscious effort to drink more water (pee nearly clear by noon and stay that way until bedtime) and see if it helps!

could be Hypoglycemia...I had that problem as a kid...I passed out a few times and as a result was tested for both diabetes and hypoglycemia...aka "low blood sugar". I have found that if I eat some candy, drink juice or eat/drink something with sugar in it, the dizziness goes away within minutes and I can go on with my life.

Quick answer... there are many causes, but one of them can be anemia, or internal bleeding, or the side effects of some medications. Low blood pressure can make you feel dizzy, or you can faint if you stand too quickly after sitting or lying down.

The most common reason for lightheadedness when you sit up or stand up is that not enough time was allowed for the blood to reach your head.  The next question though, is why are you feeling that way now and maybe your weren't before.  Things to consider are whether you started any new medications recently, suffered any injuries, have gone through any dramatic life changes, etc.  If it persists, then I believe conventional wisdom would be to consult with your family physician.  As a safety measure, when you suddenly sit up....pause for a few seconds before actually standing up and walking.  Give blood a chance to get circulating.

There's so many things that can cause dizziness.  I got new glasses one time and was dizzy for a while because the perscription wasn't right.  You could have a lot of stress too, which can make you dizzy.  Some people feel a slight buzz in their head, usually shooting straight back from your forehead along the sides of your head.  You could also have an ear wax build up.  Since you had those other tests ruled out, you might also ask your doctor about Lyme's Disease, depending on where you live.  You can get it anywhere, but it's really uncommon in some parts.  I live in Pennsylvania, and it's a lot more prevalent here, and one of the symptoms is dizziness.  Either way, don't give up.  It's hard going back into the doctor's office time and time again.

If you mean why does it feel as if your heart is beating in your head or hand or foot, etc?  Well sometimes when your blood pressure changes the added intensity of flow will cause your extremity to "beat" but it is just your blood moving through your arteries and each "beat" is a surge of blood.  It happens when you have been exercising, get excited, have a sudden bust of adrenaline or even if your circulation was temporarily cut off and it has recently been restarted (like when you sit on your foot or cross your legs).\n\n\nIts nothing to worry about unless it happens a lot.  If it happens often you could have hypertension and should ask your doctor about it.

Maybe they are pulling too much fluid from you and making your blood pressure drop too low.(ask the nurse if your BP is low when you feel like that) Or if you have big weight gains between treatments, it makes you sick when they have to remove so much in such a short time. That will make you feel nauseated and light headed. Remember, healthy kidneys work 24/7 so it's quiet a shock to the body when so much has to be removed each treatment.\nFind out what your "dry or optimum" weight is and try to keep your weight gain to no more than 2 Kilos(4.4 pounds) between treatments. If you are a new patient, this is common and should get better as you adjust. Also, try to learn everything else you can about your condition and your dialysis treatments.

I don't really understand your question exactly but if you are saying that you get dizzy when you turn over, you may have a particular type of dizziness called BPPV (Benign Paroxysmal Positional Vertigo).  This is very treatable!  I work for an audiologist and she treats people all the time.  You should see an audiologist or ear, nose and throat doctor so that they can diagnose your balance disorder and do the proper testing.

Something very simple that can cause you to be dizzy is an inner ear infection or wax build up in the ear.  I have an over active wax maker and when I get too much it causes pressure on the inner ear and makes an unbalanced situation.  It will really make you dizzy to the point of falling sometimes.  Have your health practitioner check your ears.

There could be several reasons that you are having dizzy spells.\nThe biggest one is probably not enough calories, and not eating before exercising.  Have an apple with a bit of peanut butter, or low-carb granola bar 30min-1 hr before exercising.  The bare minimum for a woman for calories is 1200, and if you are exercising regularly that probably isn't sufficient.\nYou also need to be sure that you are getting plenty of fluids.  Dizziness could be due to a drop in blood pressure due to dehydration.  Your best bet would be to consult your physician before starting a new diet/exercise plan, especially if you are severely overweight, live a sedentary lifestyle, and/or have pre-existing health problems.

it's either high blood pressure or an iron deficiency. You should also check and see if it's a low grade ear infection...something like that can throw off your equilibrium and make you dizzy during extreme motions(which include bending over and rolling over)...\n\ngood luck!

Generally common in young people , but low blood pressure is vague term, importantly if your blood pressure is generally low and you are asymptomatic, that means its not causing you any problems, only thing your doctor can advise is to increase caffeine/salt intake, But low blood pressure which has come on suddenly and causing you dizziness and fainting needs to be investigated by your doctor. In nutshell, if you have low blood pressure and no symptoms, consider yourself lucky and maintain healthy lifestyle, if on other hand, its come on recently and its giving you problems, you need to see doctor
