How Does Potassium Help To Lower Your Blood Pressure
Potassium plays a role in how much fluid is stored in your body, and how much is released in your urine. If your body is holding onto water, there will be more fluid in your blood. This puts extra pressure against your blood vessels walls, raising your blood pressure.
Normally, excess fluid is removed from your blood by your kidneys and filtered into the bladder. This process involves a fine balance of sodium and potassium.
Sodium is the part of salt that puts up our blood pressures. If you eat too much salt, there will be more sodium in your blood, and the sodium holds onto water. This upsets the fine balance of sodium and potassium that is needed for water to be pulled out of the blood and into the kidneys.
Can Vitamin D Raise Blood Pressure
Vitamin D can potentially have an effect on blood pressure levels. However, there is currently no definitive answer on whether it can raise or lower blood pressure. Vitamin D is thought to play an important role in regulating the bodys functions, including the cardiovascular system.
Some research has suggested that low levels of vitamin D correlate to higher risks of cardiovascular diseases, including hypertension. Additionally, one study found that vitamin D supplementation could lower systolic blood pressure levels in older individuals.
But, there is still much more research needed to determine its exact effects on blood pressure.
At this point, it is difficult to say whether or not vitamin D can raise blood pressure. It is important to speak to your doctor before taking supplements and make sure that they are right for you. Additionally, eating foods rich in vitamin D and getting adequate sun exposure can help your body get the recommended daily allowance of vitamin D.
How Does Hyperkalemia Affect The Body
Potassium is a mineral that is crucial for normal cell function in the body, including heart muscle cells. The body gets potassium through foods.
The right level of potassium is key. The kidneys are primarily responsible for maintaining the bodys total potassium content by balancing potassium intake with potassium excretion. If intake of potassium far outweighs the kidneys ability to remove it, or if kidney function decreases, there can be too much potassium and hyperkalemia may occur.
Potassium and sodium concentrations play a crucial role in electric signal functioning of the hearts middle thick muscle layer, known as the myocardium. An above normal level of potassium can interfere with proper electric signals in that muscle layer and lead to different types of heart arrhythmias.

Effects Of High Blood Pressure
Unfortunately, 20 percent of people who suffer from high blood pressure are unaware of the condition, significantly increasing their risk of health problems. With uncontrolled or poorly controlled hypertension, you increase the risk of significant health effects that reduce your quality of life and longevity.
Hypertension increases your risk of stroke, since it can cause blood vessels in your brain to rupture or clog more easily. In both instances, oxygen supply to a portion of the brain ceases and a stroke results.26 The increased workload on the heart muscle may result in heart failure, and damage to the arteries supplying the heart muscle with oxygen may result in a heart attack.
Hypertension may damage smaller arteries, reducing the amount of oxygen delivered and severely impacting the ability of organs to function, such as your kidneys and eyes. This may result in kidney failure and vision loss. The damage to smaller blood vessels is called microvascular disease and may lead to angina, or chest pain, when the heart muscle doesnt get enough oxygen.
Atherosclerosis is another form of damage to the arterial system from hypertension that may result in peripheral vascular disease. The narrowing of the arteries may occur in the legs, arms, stomach, and head, triggering pain and fatigue.
Hypokalemia Diagnosis And Treatment
If your doctor suspects you have low potassium levels, he or she will first obtain tests of your blood to measure the amount of potassium circulating in your body. Normal blood potassium levels range from 3.6 to 5.2 millimoles per liter of blood. Your doctor also may obtain an ECG for hypokalemia to look for heart .
A serum potassium level below 2.5 mmol/L is a medical emergency because it can lead to and death. The patient will be treated in the hospital with immediate infusions of potassium through an intravenous line, along with potential other treatments to stabilize the heart rhythm.
For low potassium levels that are not considered critical, your doctor may recommend other treatments, including:
-
Changing your prescription medicine for high blood pressure, heart failure, or to a drug that helps your body retain more potassium
-
Increasing your consumption of potassium-rich foods, such as bananas, sweet potatoes, poultry, and tomatoes
-
Potassium supplements, which normally should be taken only on the advice of a physician
-
Using table salt substitute products that contain mostly potassium instead of sodium

What Is High Blood Pressure
When your physician takes your blood pressure, he uses a sphygmomanometer to measure the amount of pressure your heart exerts to push blood through your arterial system. The top number represents the highest pressure needed, and the bottom number the lowest pressure needed. These numbers are related to the elasticity and diameter of your arterial walls.
When the pressure required to circulate your blood is high, it places an abnormal amount of stress on your heart muscle and smaller arteries, and reduces the amount of oxygen delivered to the smallest blood vessels in your body. Both of these consequences account for many of the secondary effects of hypertension.
Your blood pressure reading can vary throughout the day, so one high reading isnt a concern. Its only when your blood pressure is consistently or chronically higher than normal that significant health conditions may occur.
The validity of your blood pressure reading will be affected by the size of the blood pressure cuff, the position of the cuff on your arm, and whether youre nervous. Measuring your blood pressure in both arms at the same office visit may also give vital information about your circulatory health.
A number of studies have revealed that a significant difference between your right and left arm pressure may indicate circulatory problems that raise your risk for stroke, peripheral artery disease, or other cardiovascular problems.
Can You Have Too Much Potassium
It is possible to have too much potassium. This is a particular concern in people with chronic kidney disease . An excess can lead to a condition called hyperkalemia, and its a serious concern. Dr. Beavers notes that it can cause electrical malfunctions in your heart, and it can eventually begin to stiffen and calcify your arteries. It can also lead to kidney damage when your urinary system is unable to eliminate the excess.
If youre worried youre taking too much potassium, watch out for these warning signs:
- Heart palpitations
Too high potassium levels can be a sign of underlying kidney disease or even renal failure. If you experience any of these symptoms and arent taking a potassium supplement or eating a lot of potassium, your potassium excretion may be impaired. If this is the case, talk to your healthcare provider.

How To Take It
Potassium supplements, other than the small amount included in a multivitamin, should be taken only under your doctor’s supervision. DO NOT give potassium supplements to a child unless your doctor prescribes it.
Adequate intake of potassium from dietary sources are as follows:
Pediatric
- Infants, birth to 6 months: 400 mg/day
- Infants, 7 months to 12 months: 700 mg/day
- Children, 1 to 3 years: 3 grams /day
- Children, 4 to 8 years: 3.8 grams /day
- Children, 9 to 13 years: 4.5 grams /day
Adult
- Adults, 19 years and older: 4.7 grams /day
- Pregnant women: 4.7 grams /day
- Breastfeeding women: 5.1 grams /day
How Long Does It Take For Potassium To Lower Blood Pressure
Its important to recognize the effect of potassium is not immediate. Its not like you can eat a banana and thenboomfive minutes later, youre less hypertensive, with lower cardiovascular risk.
And, dietary approaches dont work in all circumstances. If we have someone thats in the emergency room with high blood pressure, were not going to push potassium, explains Dr. Dixon. Its going to be a couple different blood pressure lowering drugs that would be much more effective in that case.
It will take weeks to months to lower blood pressure using potassium. Thats why eating a balanced diet and changing your lifestyle to prioritize heart health over the long haul is important. If you eat properly, youll likely get enough potassium just through your food. The best option is to combine that diet with other actionable steps to maintain healthy blood pressure levels: getting regular exercise, avoiding cigarettes, maintaining a healthy weight, and decreasing sodium intake.

If were all fortunate enough to live into our late 70s or into the eighth and ninth decade of life, at some point your blood pressure may creep up a little bit and meet that threshold of hypertension, Dr. Dixon says. But theres a lot we can do in our younger years to delay that as much as possible and hopefully prevent it.

How Many Bananas A Day To Lower Bp
It is not recommended to consume more than 1-2 servings of bananas per day to lower your blood pressure. Some research shows that consuming up to three servings of potassium-rich foods per day may be beneficial for individuals with high blood pressure, however it is important to speak with a doctor before making any drastic changes to dietary habits.
Consuming a diet that is high in potassium has been linked to a lower blood pressure level, and bananas are one food that is a good source of potassium. The amount of potassium found in one medium-sized banana is 422 mg, which is considerable compared to many foods.
A serving of banana can provide a fairly substantial boost of potassium, as well as dietary fiber and various vitamins like vitamin A, vitamin B-6, vitamin C, magnesium, phosphorus, and folate.
In addition to maintaining a healthy diet, it is important to engage in regular physical activity and keep stress levels to a minimum. Studies have shown that reducing stress can help to lower blood pressure.
Therefore, making lifestyle modifications in addition to consuming a diet rich in potassium-filled foods may be beneficial for individuals hoping to maintain a healthy blood pressure level.
What Is Normal Blood Pressure For A 70 Year Old
The normal range of blood pressure for an individual aged 70 years or older is typically anywhere between 90/60 mmHg and 140/90 mmHg. However, the specific range may vary depending on other factors such as overall health, lifestyle and risk factors.
Generally speaking, anything below 120/80 mmHg is considered good for individuals in this age group. Prehypertension is defined as a systolic pressure between 120 mmHg and 139 mmHg and a diastolic pressure of 80 mmHg to 89 mmHg.
Hypertension is diagnosed when a person has a systolic pressure of 140 mmHg or higher and a diastolic pressure of 90 mmHg or higher. Therefore, a 70 year old should aim for maintaining blood pressure readings that are below 120/80 mmHg.

- American Society of Nephrology
- Summary:
- As a risk factor for high blood pressure, low levels of potassium in the diet may be as important as high levels of sodium — especially among African-Americans, according to new research.
As a risk factor for high blood pressure, low levels of potassium in the diet may be as important as high levels of sodiumespecially among African Americans, according to research being presented at the American Society of Nephrology’s 41st Annual Meeting and Scientific Exposition in Philadelphia, Pennsylvania.
“There has been a lot of publicity about lowering salt or sodium in the diet in order to lower blood pressure, but not enough on increasing dietary potassium,” comments lead author Susan Hedayati, MD, of the University of Texas Southwestern Medical Center in Dallas, Texas, and the Dallas VA Medical Center.
The new study suggests that low potassium may be a particularly important contributor to high blood pressure among African Americans, and also identifies a gene that may influence potassium’s effects on blood pressure.
The relationship between low potassium and high blood pressure remained significant even when age, race, and other cardiovascular risk factorsincluding high cholesterol, diabetes, and smokingwere taken into account.
Research performed in the laboratory of Dr. Chou-Long Huang, a co-author of this study, has found evidence that a specific gene, called WNK1, may be responsible for potassium’s effects on blood pressure.

Should You Take Potassium Supplements
Over-the-counter potassium supplements are not recommended.
In the US, food authorities limit potassium in over-the-counter supplements to just 99 mg. In comparison, a medium banana contains 422 mg of potassium .
This limit is likely low because studies have shown that high-dose potassium supplements may damage the gut or lead to an abnormal heartbeat, which is fatal (27,
That said, its fine to take a higher-dose potassium supplement if your doctor prescribes it.
Summary Its not recommended to take over-the-counter potassium supplements, as they are limited to only 99 mg of potassium. Also, studies have linked them to adverse conditions.

What Does Low Potassium Feel Like
Low potassium can be a feeling of pins and needles in the feet, hands, and brain. Its a common condition that can lead to problems such as weakness, dizziness, and headaches.
If you have low potassium, its important to get help from a doctor to find out whats causing it and figure out the best way to manage it.
Effects On Your Kidneys
High potassium doesnt cause kidney conditions, but its generally directly related to your kidneys. You may be more susceptible to high potassium if you have kidney failure or another kidney condition. Thats because your kidneys are meant to balance the potassium levels in your body.
Your body absorbs potassium through foods, drinks, and sometimes supplements. Your kidneys excrete leftover potassium through your urine. But if your kidneys arent working as they should, your body may not be able to remove extra potassium.
High potassium may also cause other symptoms and effects. This includes:
- abdominal conditions, including nausea, vomiting, diarrhea, and cramping
- numbness or tingling in your arms, hands, legs, or feet
- changes in mood, such as irritability
- muscle weakness
These symptoms may slowly develop in your body and be so mild that you dont even notice them. Subtle symptoms could make it difficult to diagnose high potassium. Its important to see your doctor for routine bloodwork on a regular basis.
