Here’s Why You Feel Dizzy When Standing Up
Published | 6 min read
Do you feel dizzy when standing up? If so, it could be due to low blood pressure. Here's when you should seek medical attention.
Have you ever wondered why you sometimes feel
Read on to learn why you sometimes feel dizzy when standing up and how to support your health to alleviate this symptom.
Why Do I Feel Dizzy When Standing Up?
When you stand up from a seated or lying position suddenly, gravity causes blood to rush to your feet. Your blood pressure suddenly drops, causing temporary dizziness or lightheadedness. The situation usually resolves immediately.
You should be concerned if your symptoms are more severe and frequent. Fainting and falling from dizziness could result in concussions and even bone fractures. Fluctuations in blood pressure also increase your risk of shock or organ failure and even stroke.
The following are some underlying reasons why you could be feeling dizzy when standing up:
Dysfunction of the autonomic system
Blood pressure regulation is part of the body’s autonomic system. In a healthy body, blood pressure normalizes without us having to think about it.
Orthostatic hypotension can be a symptom of autonomic dysfunction. Diseases that cause autonomic dysfunction include type 2 diabetes,
Postural orthostatic tachycardia syndrome (POTS) is a rarer condition related to autonomic dysfunction. It also involves dizziness when standing up, followed by a sudden increase in heartbeat rate.
Certain medications
Medication for high blood pressure, like vasodilators and alpha-blockers, sometimes over-corrects and lowers blood pressure too much.
Diuretics can cause excessive water discharge, resulting in hypotension. Some psychiatric medications can also lower blood pressure.
Dehydration
Blood is mostly made of water, and when you’re dehydrated, your blood volume drops, leading to hypotension. One of the most immediate symptoms of dehydration is feeling dizzy when rising from a seated or lying position.
Anemia
Low levels of hemoglobin in anemia result in less oxygen reaching the brain, causing low blood pressure. Dizziness upon standing up is a common symptom of this condition.
Underlying heart or lung problems
Heart conditions like arrhythmias or heart valve disease impair the heart’s ability to pump blood adequately. Lungs with compromised function can affect oxygen levels in the blood. Both of these issues can cause hypotension.
TCM’s View On Dizzy When Standing Up
In Traditional Chinese Medicine (TCM), chronic orthostatic hypotension can be traced back to two common syndromes.
“Qi (vital life force) and blood that flow smoothly to support the head and face support a change in body position, especially from a lower to a higher position. A lack of qi and blood results in dizziness and blurred vision.”
TCM physician Ho Li Ying.
“Meanwhile, Phlegm-Dampness can easily obstruct the overall flow of qi and blood. Even with sufficient qi and blood, these substances won’t be able to support all organs in the body if Phlegm-Dampness is severe. Therefore, when there is a change in body position, dizziness resembling Qi Blood Deficiency will occur,” she further elaborates.
What To Do If You Feel Dizzy When Standing Up
To prevent frequent episodes of orthostatic hypotension:
- Get up from sitting or lying down slowly.
- Instead of sleeping flat on your back, keep your head elevated.
- Drink some water when you get up in the morning when blood pressure is typically lowest.
- Wear compression garments and do isometric leg exercises that help keep blood from pooling at your feet when you stand up.
- Talk to your doctor about changing the medication that’s causing your dizziness.
- Eat smaller meals and less refined carbohydrates. Digestion of large high-carbohydrate meals diverts blood from other parts of your body.
Herbal medicine
Fortunately, TCM remedies also target the root of what may be causing chronic low blood pressure.
In 2016, researchers in Chongqing, China, found Ba Zhen Tang or Eight Treasures soup to be effective in enhancing the formation of cellular components of blood, replenishing qi and blood.
Other herbs that help include:
- Codonopsis and red date tea (dang shen hong zhao cha)
- American ginseng (hua qi shen)
- Longan fruit (gui yuan)

Consult A Physician About Why You Feel Dizzy When Standing Up
Monitor how often you feel dizziness when standing up. We often hear of high blood pressure being a health concern as we enter midlife, but symptomatic low blood pressure, including orthostatic hypotension, can also indicate serious problems. Remember to consult a qualified TCM practitioner before trying any of the above herbal formulations.
