Whenever I've been sitting for a long period of time and I get up my vision gets very out of focus and black. My body gets very weak and it gets hard to remain standing and normally have to sit on the ground for a few seconds for it to go away.
What is this? Thanks in advance.

It could be orthostatic hypotension- your blood pressure lowering when you go from standing to sitting. The change in position causes a temporary reduction in blood flow and therefore a shortage of oxygen to the brain. This leads to lightheadedness and, sometimes, a "black out" episode, a loss of consciousness.
Symptoms include dizziness, feeling about to black out, and tunnel vision (all due to insufficient bloodflow to the brain). The symptoms are typically worse when standing and improve with lying down.
In healthy people, muscle contraction increases venous return of blood to the heart through one-way valves that prevent blood from pooling in dependent parts of the body. The autonomic nervous system responds to changes in position by constricting veins and arteries and increasing heart rate and cardiac contractility. When these mechanisms are faulty or if the patient is hypovolemic, orthostatic hypotension may occur. In persons with orthostatic hypotension, gravitational opposition to venous return causes a decrease in blood pressure and threatens cerebral ischemia. Several potential causes of orthostatic hypotension include medications; non-neurogenic causes such as impaired venous return, hypovolemia, and cardiac insufficiency; and neurogenic causes such as multisystem atrophy and diabetic neuropathy.
I have this same problem- I've even completely passed out before. I just have to remember to stand veeeery slowly.

That happens to me a lot. It means that your blood pressure is too low, above the level of your heart. This is called "orthostatic hypotension". The way to compensate is to sit up first, for 15-20 seconds and then stand up slowly. This problem is not unusual, as we age.

That happens to me too. From my understanding, it's simply the blood rushing to your head. It's nothing abnormal, but you might want to get yourself checked by a doctor if it occurs frequently. It could mean you have low blood sugar or iron, but it's not too likely. Also, try standing up slower. This will help the blood to slow down when you stand.

It's called orthostatic hypotention. It is a sudden drop in your blood pressure. Your blood rushes out of your head when you move quickly like that. It is something that you should talk to your doctor about and in the mean time, get up very slowly and no sudden moves.

Unless you are one some kind of medication that would cause those symptoms...your blood pressure may be low or you may be anemic. Sorry but your doc can answer that question with a simple blood test.

Bad circulation and not enough oxygen. You should probably see a doctor.
In the meantime, maybe try eating healthier and excersize(sp?) more.
