Dehydration Affects Blood Pressure Lab Blood Test Results
Dehydration is one of several factors that should be considered when inaccurate blood test results are suspected. Water accounts for approximately 60% of an adult humans body weight, and impacts virtually every system in the bodyincluding the circulatory system. Which blood tests are most commonly affected by dehydration? Learn more below.
How Much Water Should You Drink
There is no one-size-fits-all recommendation for how much water or fluid you need to stay well hydrated throughout the day, Dr. Conroy says. Eight, eight-ounce glasses of water a day is a good starting-off point for the average person.
If you are physically active all day, you may need more water than someone who is more of a couch potato, he says.
You really have to pay attention to body size and activity level, Dr. Conroy says.
Not all liquids are created equally when it comes to hydration either, he says. Alcohol and caffeine can dehydrate you so you are better off sticking with water or juice.
Gatorade or another electrolyte drink also can help you rehydrate, but these tend to be high in sugar, he says. These drinks replace electrolytes or minerals, such as sodium, potassium, chloride, magnesium, calcium, phosphate, and bicarbonate which dissolve in the bodys fluids. This can be important as dehydration can also lead to electrolyte imbalance.

How Does Dehydration Have Different Effects On Blood Pressure
When youre dehydrated, you can lose water, salt, or a mixture of the two. Its most common for humans to lose both salt and water at the same time. If youve lost too much fluid, water found surrounding your cells can move into the bloodstream to help maintain blood pressure and keep your organs and tissues well supplied. But, when your salt level is also reduced, water cant move as effectively into the bloodstream to counter low blood pressure. Dehydration with salt depletion is known to have a bigger effect on blood pressure than water loss on its own .

Enhancing Healthcare Team Outcomes
Often because water intake is not the most pressing topic for the average clinical visit, it is often overlooked regarding patient care. If we can encourage more healthy lifestyle choices and daily hydration, it can lead to decreased morbidity, mortality, and complications associated with dehydration. Healthcare providers should look toward implementing more incentives and initiatives toward increasing hydration amongst staff and patient populations.
Dehydration And Low Blood Pressure: Whats The Catch
Just like high blood pressure, dehydration can also cause low blood pressure. It is however not a very potential marker but if not paid attention to, can lead to detrimental outcomes.
Dehydration can cause low blood pressure due to a decrease in blood volume . This can ultimately cause cell starvation resulting in fatigue and weakness. An adequate blood flow is essential to be able to reach all the body tissues.

Fluids Matter To The Heart
Dehydration causes your blood volumethe amount of blood circulating throughout your bodyto decrease. As a result, sodium levels in the blood increases, thickening the blood and making it harder for it to circulate. In turn, this taxes your heart muscles even more. The result: Your heart rate rises and blood pressure may drop. Its amazing, because you can actually see on an echocardiogram, an ultrasound of the heart, if someones dehydrated, Dr. Steinbaum says.
In someone with heart issues, including intermittent cardiac arrhythmias such as atrial fibrillation, dehydration can cause changes in heart function as well. Significant shifts in fluid levels in the heart chambers can theoretically trigger the rhythm disturbance, although this is rare, says Alon Gitig, M.D., a cardiologist and director of cardiology at Mount Sinai Doctors Westchester and assistant professor of medicine at Icahn School of Medicine at Mount Sinai in New York City. Dr. Gitig says avoiding dehydration is most important for cardiac patients with a tendency toward low blood pressure. Many medications commonly used in management of congestive heart failure, coronary artery disease, or arrhythmias have the potential to lower blood pressure, he explains. This effect is exacerbated if the arteries and veins are circulating less blood volume.

Different Types Of Hypertension
Essential hypertension
In 95 percent of high blood pressure cases, the underlying cause cannot be found. This type of high blood pressure is called “essential hypertension.” High blood pressure tends to run in families and is more likely to affect men than women. Essential hypertension is also greatly influenced by diet and lifestyle. Most people with high blood pressure are salt sensitive, and a slight increase in salt intake may increase their blood pressure.
Secondary hypertension
When a direct cause for high blood pressure can be identified, the condition is described as secondary hypertension. Among the known causes of secondary hypertension, kidney disease ranks the highest. Hypertension can also be triggered by tumors or other abnormalities that cause the adrenal glands to secrete excess amounts of the hormones that elevate blood pressure. Birth control pills and pregnancy can boost blood pressure.

Hypertension Can Be Caused By Chronic Dehydration
Are you stressed? Most of us think we’re stressed, but perhaps you’re not. Maybe you’re just thirsty. Research has shown that hypertension and dehydration are linked. Maybe by drinking more, you’ll be less stressed.
Hypertension is a significant disease. It is a cause of some some life-threatening conditions such as heart attacks, hormonal disorders, cardiovascular disease, kidney failures, and strokes. Drinking lots of water is one way that you can fight hypertension without a major lifestyle adjustment.
Blood pressure depends on two factors – how hard your heart is pumping and how easily plasma diffuses out of your capillaries . Studies have shown the majority of people with hypertension have normal cardiac output but increased peripheral resistance. It is thought that one of the likely causes of this is dehydration.
When you’re dehydrated, the volume of blood in your body decreases. Your body’s internal water rationing system keeps your essential organs hydrated but it does this by shutting down the capillaries that supply your muscles and skin. If you drink enough fluids , you’ll keep an adequate volume of blood in your body and therefore reduce your risk of hypertension.
Hypertension can be avoided when you pay attention to proper eating and lifestyle choices. Drinking pure water is important for staying healthy. So instead of stressing about something, have a drink of water instead!

Can Dehydration Affect Your Blood Pressure
Because of the high intake of caffeinated drinks, alcohol, and a diet packed with sodium, people are struggling with chronic dehydration.
In fact, 75% of Americans have chronic dehydration. Depriving the body of fluids activates thirst response, causing irritability, memory fog, and poor cognitive function.
The older population is 20% to 30% more likely to become dehydrated. Health problems such as renal illnesses, diabetes, immobility, and impaired thirst mechanism make them prone to experiencing inadequate fluid intake.
When left unmanaged, it can have serious consequences, like kidney disease. Many people want to know does drinking water lower blood pressure, including whether fluid deprivation can cause drastic blood pressure fluctuations.
This guide provides a detailed analysis of the impact of fluids on the blood. Here is all you need to know about hydration before your next blood pressure reading.

Your Skin Is Rough And Flaking
One of the main ways we lose water is through our epidermis. We lose water when we sweat, and we also lose water when it’s cold because the air is drier and sucks the moisture out of us. If your skin is rough, cracking or flaking, you could use more water. Other signs include redness or tightening. If your skin is constantly cold and clammy, you could be dehydrated as a symptom of diabetes, so make sure to check with your doctor.
If you want to check your skin for dehydration, pinch a small area of your cheek. If it wrinkles, you need to drink more fluids.

What Causes Dehydration
Dehydration is the result of your body losing water more quickly than you can take it and other fluids in. The result is that your body can struggle to go about its normal functions. If you dont replace the lost fluids, you become dehydrated.
During pregnancy, this is especially worrisome. Water is used to form the placenta, which passes nutrients to your growing baby. Its also used in the amniotic sac. Dehydration during pregnancy can result in very serious complications, including:
- neural tube defects
- poor production of breast milk
- birth defects
Your body is using water in greater amounts during your pregnancy. Dehydration is automatically a concern if you arent taking care to replace lost fluids.
If youre dealing with morning sickness that makes it difficult to keep anything down, dehydration becomes even more likely. Vomiting can lead to a lack of fluids and electrolytes, plus the loss of stomach acid.
As you move further into your pregnancy, overheating can also become an issue, which is another precursor to dehydration. Other common causes of dehydration include:
- vigorous exercise, particularly if the weather is warm
- intense diarrhea
- constipation
- dizziness
If youre experiencing these symptoms, drink water, and rest if you can. Its also a good idea to call your doctor and explain what youre feeling.
Symptoms of severe dehydration include:
- extreme thirst
- rapid heartbeat and breathing
- low blood pressure

Why Is My Heart Racing
Considering the incredible job your heart doeskeeping you alive by pumping blood to provide your body with the oxygen and nutrients it needsyou probably dont often think about how hard it works every second of the day.

How To Stay Hydrated If Youre Managing Type 2 Diabetes
Even if scientists still have questions about how dehydration affects the body, staying hydrated is clearly important for good health especially if you have type 2 diabetes.
So how can you make sure youre getting enough water to manage diabetes? Rizza and Simos offer the following tips.
Have some salt but not too much. Too much salt can be bad for blood pressure, Rizza says, but you do need some to maintain proper hydration. When you eat salt, notes the U.S. National Library of Medicine, you help stabilize your electrolytes, which are charged substances that regulate essential functions in your body, helping you stay hydrated. If you already have high blood pressure, talk with your doctor about how much salt to consume.
Check your blood glucose levels in extreme heat, and drink water if they are elevated. When its hot, its easier to become dehydrated, according to Johns Hopkins Medicine. Staying well hydrated can help reduce your blood glucose levels, which helps you manage the hormone insulin, Simos explains. And make sure that your blood glucose test strips and insulin are stored in a cool, dry place, she says, so that they dont lose their potency and accuracy.
Reach for hydrating snacks if youre hungry. For example, choose a cold piece of melon or a few frozen grapes, Simos says. Drinking a glass of water isnt the only way to get your fix.
