Why You Get Dizzy When You Stand Up

By David Blyweiss, M.D., Advanced Natural Wellness

Do you ever have that weird thing happen where you stand up and get dizzy? A lot of people think it’s because they stood up too fast. But it’s really more a function of your blood flow.

When you sit for a while, gravity causes blood to pool in your legs and feet. Then, when you stand up, more of it flows downward and you briefly have a reduced amount of blood available to your heart in the upper body. So it’s basically a form of low blood pressure that happens when you stand up.

It’s not uncommon. There’s even an official name for it. It’s called “orthostatic hypotension.”

If it’s an occasional issue, it’s probably not a problem. If it happens to you a lot, it could be because of an underlying condition – or maybe because some of the medications you’re taking.

Occasional dizziness upon standing could be triggered because you’re dehydrated, which reduces your blood volume. Low blood sugar or being overly hot can also trigger it.

If it occurs frequently, health conditions such as heart disease, diabetes, thyroid issues or neurological conditions like Parkinson’s or dementia may be the underlying cause. Diuretics, blood pressure drugs, beta blockers, antidepressants and drugs used for erectile dysfunction can all contribute to the severity of orthostatic hypertension.

As a matter of fact, my Dad was on the alpha-blocker Flomax for a while. When he got up to go to the bathroom one night, he became so lightheaded that he passed out and cracked his head on the floor. And that’s never a good thing. But I’ve similar stories from any number of men on the drug.

Thankfully, there are a few things you can do to get your blood flowing more quickly to your heart when you stand up.

Stop Dizziness – Prime Your Body Before Standing

It turns out if you “prime the pump” before standing, it can make all the difference when it comes to dizziness.

As you prepare to stand, take several very deep breaths. Just slowly inhale through your nose for a count of four, and hold it for a count of seven. Then exhale through pursed, rounded lips for a count of eight. Do this several times.

Next, start raising your legs like you are marching in place while seated. Do this for 30 seconds or so prior to standing.

Then stand up slowly and tense up your lower limbs by crossing your legs while clenching the muscles in your butt and thighs. This will help push the blood into your upper body.

Keep in mind that, if you have poor balance, it may not be a good idea for you to try and cross your legs while standing. That could lead to a fall. So if you have balance issues try doing a few leg crosses while sitting, then only clench your butt and thighs when you stand.

Get Checked Out for Underlying Conditions

If you frequently experience dizziness, blurred vision or light-headedness when standing, I recommended bringing it to the attention of your physician. It may due to a health condition you are unaware of, or one of the medications you are taking.

In the event you feel as though you will faint after standing, sit back down immediately and place your head between your knees (crash position) until you recover.

In the meantime, eat regularly scheduled healthy meals to keep your blood sugar up and stay hydrated. Water keeps your blood from getting too thick so it can flow more easily to your heart.
