A higher potassium intake causes the excretion of more sodium through urine, which can help lower high blood pressure. While both sodium and potassium are important, sodium is often consumed in excess, while potassium is deficient in many diets. In this series, we will examine some of the how levels of sodium, potassium, calcium, and magnesium are related to other electrolytes. Also, while potassium might not directly be affected by mag, it is very closely related to cortisol on its own and magnesium can lower cortisol. Sodium and potassium are two electrolytes that are required for human survival. Sodium, in the form of salt, is abundant in the human diet and excessive intake often leads to high blood pressure. Too much salt in your diet paired with inadequate intake of potassium-rich foods can lead to a buildup of sodium levels in your bloodstream, which in turn may put you at risk for disease. Potassium deficiency can be related to, or exacerbated by, magnesium deficiency as these electrolytes have a similar relationship. This post will focus on sodium and potassium. The sodium-potassium pump can be quite a perplexing topic especially to nursing students due to its nature, function, and how the entire process contributes to healthier well-being. MedlinePlus: Fluid and Electrolyte Balance, American Heart Association: Striking a Balance: Less Sodium (Salt), More Potassium, The American Journal of Clinical Nutrition: Relations Between Dietary Sodium and Potassium Intakes and Mortality from Cardiovascular Disease: The Japan Collaborative Cohort Study for Evaluation of Cancer Risks, PARTNER & LICENSEE OF THE LIVESTRONG FOUNDATION. in an article on the AHA website.

Sodium and potassium have complementary functions in the body, helping to regulate things like fluid balance and blood pressure. ALL Rights Reserved. Relationship of urinary sodium/potassium excretion and calcium intake to blood pressure and prevalence of hypertension among older Chinese vegetarians Eur J Clin Nutr. So potassium will lower the blood pressure. Both nutrients have been linked to risk of chronic disease, particularly cardiovascular disease. any of the products or services that are advertised on the web site. Potassium can aid in the removal of excess sodium from the body, which can help lower blood pressure. Maintaining the right balance of electrolytes is important for the body's biochemistry, muscles as well as other processes. Cell membranes contain sodium-potassium pumps that regulate the balance of sodium and potassium intra- and extra- cellularly. 2003 Feb;57(2):299-304. doi: 10.1038/sj.ejcn.1601553. Cell membranes contain sodium-potassium pumps that regulate the balance of sodium and potassium intra- and extra- cellularly. The epidemiologic evidence connecting sodium intake to blood pressure has often been confounded by reciprocal changes in potassium intake. Copyright Policy If the average American sodium intake was cut to less than 1500 milligrams per day, the cases of high blood pressure would decrease by about 26 percent, which would result in more than a $26 billion yearly savings in healthcare costs, according to 2014 information provided the AHA. Less fluid in the body: In older people, the body contains less fluid. Esme12, ASN, … However, for cardiovascular outcomes, recent evidence suggests a J-shaped relationship with sodium intake.3,4 For potassium intake, the Kidney Disease Outcomes Quality The sodium-potassium pump regulates extracellular potassium levels by pumping sodium out of cells and allowing potassium to flow back into cells. This change means that a slight loss of fluid and sodium, as can result from a fever or from not eating and drinking enough (sometimes for only a day or two), can have more serious consequences in older people. Of note, potassium levels falling do not cause magnesium levels to fall. Electrolyte Relationships: Magnesium. The NCLEX-RN: How to Pass on the First Try, Once you have graduated from nursing school, the next big milestone on …, In this post, the third in our series on the relationships between elec…, Electrolyte Relationships: Calcium, Phosphorus, and Vitamin D, Electrolytes are responsible for a number of different functions in the…, National Council Licensure Examination-Registered Nurse® Blog, Common Cardiac Medications: Beta Blockers, Common Cardiac Medications: ACE Inhibitors. \. Sodium is often consumed in excess, which can create an imbalance that can result in high blood pressure. However, consuming more potassium does not mean you can eat as much sodium as you want, but it can serve as a tool in countering high blood pressure caused by sodium, notes Rachel K. Johnson, Ph.D., M.P.H., R.D. Acting on the distal tubules, the hormone aldosterone triggers potassium excretion and resorption of sodium. Potassium and sodium are electrolytes needed for the body to function normally and help maintain fluid and blood volume in the body. To continue reading this article, you must log in. Objective: To assess the relationship between dietary sodium intake, as measured by urinary electrolyte excretion, and blood pressure within a population of older Australian adults. Main Difference – Sodium vs Potassium. 2020 © Union Media LLC. . Electrolytes are positively and negatively charged particles that control the distribution of fluids throughout the body. tion.2 Because the relationship between sodium intake and renal outcomes is assumed to be linear, guidelines do not include a lower limit for suggested sodium intake. For this reason, you should keep an eye on the magnesium levels in patients at risk for hypokalemia, like patients taking diuretics. Since this ion movement is contrary to the concentration gradient for each ion, it requires the use of energy, hence the ATPase function of the pump. used as a substitute for professional medical advice, We need to maintain a precise balance of potassium and sodium in our cells but our intake of potassium and sodium may vary greatly from day to day.

Subscribe to Harvard Health Online for immediate access to health news and information from Harvard Medical School. A study published in the July 2008 issue of "The American Journal of Clinical Nutrition" investigated the relationship between sodium and potassium intake with regards to mortality from cardiovascular disease. The administration of magnesium is often appropriate when attempting to correct hypokalemia. Moreover, we do not select every advertiser or advertisement that appears on the web site-many of the The researchers concluded that diets high in sodium and low in potassium can raise the risk of mortality from cardiovascular disease. The exchange seen will be 2 Na and 1 H for the 3 k that left the cell. Potassium and sodium together play a huge role in regulating blood pressure, and mounting evidence shows they are intimately involved in bone health. We are dedicated to bringing you the very best practice tests, flashcards and study guides to help you prepare for and pass the test that stands between you and the rest of your life. To that end, potassium eases tension within blood vessel walls, further helping to lower blood pressure and guard against muscle cramping. This is why patients with high sodium levels are encouraged to eat foods high in potassium to encourage the kidneys to excrete more potassium. Each of these important nutrients is required for normal bodily function. Thank you for watching! Both sodium and potassium increased sugar yield and there was a large negative interaction between them. The kidneys are mainly responsible for maintaining a balance. 2020 Potassium and sodium are minerals that your body uses mainly as electrolytes, which are elements that conduct electrical signals within fluid. Sodium and potassium are two electrolytes that are required for human survival. Sodium, potassium and nitrogen fertilizers also affected the concentration … While we know that high salt intake increases blood pressure, high potassium levels lower blood pressure by relaxing the blood vessels. The kidneys are mainly responsible for maintaining a balance. , Sodium. Both sodium and potassium are very useful chemical elements because they form a wide variety of chemical compounds. L\ able on the relationship between cations A. Sodium and potassium are two electrolytes that are required for human survival. Diet and changes in the amount of water in your body that can result from vomiting, diarrhea, sweating, certain medicines or kidney problems can be the cause of high or low electrolyte levels. Eating foods high in potassium like bananas can help rid the body of excess sodium. If both sodium and potassium are low and one takes their dose of mag (whether it be the RDA of 400mg or their body-weight dose of about 800+), one can experience both low sodium and low potassium signs. Sodium and potassium have opposite effects on the heart. Symptoms of low sodium include headache, nausea and vomiting, confusion and fatigue. A high sodium to potassium level also increases the risk of obesity. and Decreasing dietary sodium intake most likely reduces blood pressure in normotensive adults and more so in those with hypertension In addition to the sodium-potassium pump, review the role of sodium and potassium in the action potential of muscle, the pancreas, and nerves. diagnosis or treatment. Based on more than 58,000 participants who were followed for a 12-year period, the study found that sodium intake was positively correlated with mortality from ischemic stroke and cardiovascular disease.

Terms of Use Privacy Policy Electrolytes are positively and negatively charged particles that control the distribution of fluids throughout the body. Copyright © Luckily, there is an inverse relationship between potassium and sodium that you can utilize, as a way to reduce the sodium in your body. Low magnesium levels can cause more potassium to leave the cells and be excreted by the kidneys, decreasing the overall level in the body. As potassium levels rise, sodium levels decrease and vice versa. Modern potassium and sodium ratio is 0.74 to 1. This can help you remember that sodium and potassium have an inverse relationship, meaning when sodium levels rise, potassium levels fall, and vice versa. You can find discussions about other electrolyte relationships in two other blogs: Electrolyte Relationships: Calcium, Phosphorus, and Vitamin D Sodium is one of the electrolytes most closely linked to the body’s fluid balance, since water tends to go to the areas of higher sodium concentration. Relationship and interaction between sodium and potassium J Am Coll Nutr. One of these oversights involves sodium and its relationship with potassium, working together as the sodium-potassium pump, which is the mechanism of active transport by which sodium and potassium ions are moved across the cell membrane, into and out of the cell. However, a person can get high blood pressure by consuming too much sodium and not enough potassium. One study found that there was a direct association between total body fat using DXA screens rather than BMI and urinary sodium to potassium ratio that was independent of other risk factors, including blood sugar, diabetes, blood pressure, and serum triglycerides. This can help you remember that sodium and potassium have an inverse relationship, meaning when sodium levels rise, potassium levels fall, and vice versa. Sodium and potassium are highly reactive chemical elements that can be found in group 1 of the periodic table. Sometimes, electrolytes can become too concentrated or too sparse in the body. In addition to consuming less dietary sodium, potassium has the power to help remove sodium from the body. At Union Test Prep, we are a small team dedicated to bringing the best test-prep material to you, free of cost. Electrolytes that most commonly cause problems include potassium, sodium and calcium. Most of the body’s supply of potassium resides inside the cells as opposed to sodium, which resides outside the cells. Once you understand the functions and normal values for electrolytes, it is important to understand how some electrolyte levels are related to others. Only 45% of body weight is fluid in older people, compared with 60% in younger people. When potassium leaves a cell an electrolyte balance must be maintained in the cell. advertisements are served by third party advertising companies. When the potassium level rises in the body, the kidneys will excrete more sodium, and when the potassium levels fall, the kidneys will excrete less sodium causing the levels to rise. 2006 Jun;25 (3 Suppl ... Dietary potassium modulates both the pressor and hypercalciuric effects of the modern dietary excess of NaCl. Clay McNight is currently a nutrition writer with Demand Media Studios. The LIVESTRONG Foundation and LIVESTRONG.COM do not endorse Often, an imbalance of one electrolyte is related to an imbalance of another electrolyte so understanding these relationships can assist in determining the root cause of, and treatment for, certain electrolyte imbalances. The role of the Na+/K+-ATPase pump is to remove the sodium ions (Na+) that came into the cell during depolarization and retrieve the potassium ions (K+) lost during repolarization. Data on the relationship between serum phosphorus and blood pressure are also scarce. It should not be Potassium activates nitric oxide to reduce pressure in the arteries, and thus, lowers the risk of hypertension. The material appearing on LIVESTRONG.COM is for educational use only. The Role of the Kidneys. In addition, interventional studies have demonstrated a kaliuretic affect of sodium loading.15 Moreover, potassium supplementation has been … They regulate the passage of fluid across cell membranes, which is important for maintaining a state of fluid balance and for transporting nutrients and waste in and out of cells. Societies in which sodium intake is traditionally low typically have a high potassium intake, primarily from fruit and vegetables.14 On the other hand, potassium intake tends to be reduced in societies where sodium intake is increased.
