What Causes Low Blood Pressure

author avatar Dr. Eric Berg 01/18/2024

Imagine standing up, and the room starts to spin, your vision blurs and you have to grip something—anything—to keep from hitting the deck. That's postural hypotension for you; it doesn't send a calendar invite before dropping by unannounced.

You might think it's because you stood up too fast or didn't drink enough water today. But sometimes, these dizzy spells are signs of an intricate dance inside your body where blood pressure dips low without much warning.

Let me walk you through some backstage secrets here—you'll get why dehydration isn't always about chugging more H2O and how a simple vitamin-like B1 could be running away with your stability.

We're also going to crack open the case on adrenal health—it's not all about stress balls—and find out why you only want a nap after that big meal instead of feeling energized.

Roller coaster. Blood pressure can be a tricky beast, often creeping up without warning or dipping low enough to leave us dizzy and disoriented. However, understanding the ins and outs of blood pressure helps us stay on track for better health.

Understanding Postural Hypotension and Its Impact on Blood Pressure

Have you ever stood up too quickly and felt like the room took a spin? That's postural hypotension, a fancy term for when your blood pressure can't keep up with your quick moves. Imagine this:

Your blood vessels are sleeping in a hammock, and suddenly, they must sprint. It's no wonder dizziness crashes the party.

This drop in blood pressure is more than just an awkward moment; it might signal something more profound. Think of POTS as postural hypotension's evil twin—except instead of simply making you dizzy, it throws heart palpitations and fatigue into the mix because why not?

However, the situation gets more complex. Low levels of vitamin B1 might be pulling some strings behind these symptoms, worsening postural hypotension.

The connection is clear as day—no B1 means more chances to play host to POTS. So next time that head spin hits after standing up consider giving those vitamins some thought.

The Role of Adrenal Health in Blood Pressure Regulation

Imagine your body as a high-stakes poker game. The adrenal glands are like the fantastic, calm players who keep things running smoothly under pressure. But when they start to tire—what we call adrenal fatigue—your blood pressure could fold like a bad hand.

This isn't just about feeling a bit off; it's about how these tiny glands atop your kidneys manage stress hormones and thus impact blood flow.

When they're exhausted, standing up too quickly might leave you dizzy or lightheaded—a classic sign of postural hypotension linked with weakened adrenals.

Moreover, this can escalate into POTS (Postural Orthostatic Tachycardia Syndrome), where even simple activities become marathons for your heart rate and circulation due to low vitamin B1 levels.

To avoid such pitfalls, keeping those adrenal players in top form is critical to steady blood pressure—and staying in the game.

Dehydration and Salt Levels as Factors in Low Blood Pressure

Imagine your body's fluid volume is like a party balloon. Not enough water? The balloon deflates, causing low blood pressure—simple, right? But dehydration does just that by reducing the fluid coursing through your veins.

We all know salt gets a bad rap, but here's where it twists—the right pinch can be vital. When salt levels drop too low, it's like opening the floodgates; fluids leave your cells faster than teens ditching a lame party.

And boom—you've got yourself another cause for dropping blood pressure.

Too much sugar, though—that's when things get dicey. So, let's keep our bodies hydrated and balanced with that salty goodness—in moderation—to stay pumped up and ready to go.

Autoimmune Influences on Blood Pressure

Imagine your body's immune system as a well-intentioned superhero who sometimes gets the wrong villain. That's what happens in Addison's disease, an autoimmune condition where the adrenal glands face friendly fire.

Addison's disease packs a punch to your sodium balance, like taking a sledgehammer to the delicate saltwater aquarium of our bodies.

When these glands get knocked out, severe sodium deficiency can swoop in and drop your blood pressure faster than you can say "hypotension."

This isn't just some rare comic book scenario; it affects real people with unique stories about managing this sneaky adversary.

And when we talk about low blood pressure due to Addison's disease, we're looking at not just numbers but lives turned upside down by something as simple as standing up too quickly.

Anemia-Related Blood Pressure Concerns

Picture this: you feel like a balloon the day after the party—deflated. That's what anemia can do to your blood pressure. When iron is in short supply, your body's red blood cells start slacking on their oxygen delivery job.

The result? You guessed it—lower blood pressure.

B12 isn't just a vitamin that health nuts rave about; it's crucial for keeping your nerves and red blood cells happy. Skimp on B12, and not only does fatigue crash the party, but low blood pressure makes an unwanted entrance, too.

If you think about it, having enough iron and B12 is like making sure there are enough chairs at musical chairs—the game doesn't work without them.

Anemic conditions toss out some of those chairs, leaving our bodily functions scrambling when the music stops (or in this case, when we stand up).

Understanding Postprandial Hypotension

Ever felt like you needed a nap after a big meal? That could be more than just a food coma. It's known as postprandial hypotension when your blood pressure takes a nosedive following that feast.

This drop is often linked to the health of your autonomic nervous system—think of it as the body's autopilot for vital functions.

If this happens often, you might want to shout at your doctor. They'll tell you how this can be an alarm bell for underlying issues with your nervous system control center.

So while that turkey sandwich isn't strictly criminal, it could be exposing some chinks in your body's armor.

The bottom line is to listen to what those post-lunch dizzies are trying to tell you about your inner workings. Your body might thank you later.

Simple Testing for Adrenal Issues and Autonomic System Weakness

Sometimes, the best way to pinpoint a sneaky health issue is by doing something surprisingly simple. Suppose you've ever felt like your energy levels dropped as quickly as your phone's battery at 1%.

In that case, it might be time to look into how well your adrenal glands and autonomic nervous system play their part in regulating blood pressure.

A straightforward test can shine a light on potential issues with these systems. It involves taking blood pressure readings while seated and then again immediately after standing up.

A significant drop in those numbers could wave red flags that point toward adrenal problems or an autonomic system not quite keeping up with the body's demands.

This isn't just about feeling momentarily woozy; consistently low readings when changing positions could signal underlying conditions needing attention—and aren't we all about catching things before they get too rowdy?

Turmeric root and supplement

Exploring its Potential in Lowering Blood Pressure 

Embark on a journey of health exploration as we delve into the intriguing question: does turmeric lower blood pressure? Turmeric, renowned for its anti-inflammatory properties, has emerged as a potential ally in promoting cardiovascular well-being.

Studies suggest that curcumin's active compound may affect blood pressure regulation.

This exploration into turmeric's influence on lowering blood pressure unfolds as a testament to the multifaceted benefits of this natural wonder, offering a potential avenue for those seeking holistic approaches to cardiovascular health.


The sources of reduced blood pressure may not always be straightforward. Remember, proper hydration is essential but not a panacea. And remember, vitamins like B1 can play more significant roles than we think.

Wrap your head around adrenal health; it's vital to check your blood pressure. Consider how after meals or standing up too quickly might make you reeling because of postural changes.

Dive deep into understanding these triggers—your body will thank you later. Tackle anemia and autoimmune disorders as part of this complex puzzle.

The take-home message? Knowing what affects your blood pressure means taking control of those unexpected drops that leave you reaching for support.

If tackling the causes of low blood pressure seems daunting, start with small steps: monitor your diet, stay hydrated, and keep tabs on symptoms that may point to deeper issues.
