It’s low blood pressure. When you have low BP, the blood that needs to get higher when you stand up quickly doesn’t have enough oomph (pressure) to get there. Think about a hose, when you turn it on a little it can water the plant in front of you, a lot and it can get the neighbor’s tree.
Now, what causes low blood pressure? Lots of things it turns out. Dehydration, exercise, various medications, and anemia which is associated with low iron. Anemia is not the only possible cause of low blood pressure. I have naturally low blood pressure but good enough iron to donate blood. Basically, your blood uses iron as an important building block so not enough of that block, not enough blood, low blood pressure, feeling faint.
Go get your blood pressure tested a few times. It’s free and automatic at a lot of pharmacy machines. Try first thing in the morning, after lunch, after a run, hungover, etc. and you’ll see how much it can change and why sometimes you feel faint and others, you don’t.
Your blood needs iron to transfer oxygen and the brain is very sensitive to a lack of oxygen. Standing up quickly lowers the blood pressure in your brain anyway and if you have a lack of iron and therefore red blood cells already it can make you feel very dizzy or pass out.

Random people have no way of knowing this. Your doctor, after examining you and probably after lab work, will be able to tell you what’s wrong.
