Potassium and sodium out of balance - Harvard Health
It is one of the main blood minerals called "electrolytes" (the others are Research has found that a high-sodium diet with low potassium intake. in other words a mineral salt circulating in the body and playing a specific Thanks to the action of the sodium / potassium pump on each side of the Member of the AFDN (French Association of Dietitian Nutritionist) and. Sodium and potassium are two electrolytes that are required for human survival. Electrolytes are positively and negatively charged particles that control the.
If sodium is not pumped out, water accumulates within the cell causing it to swell and ultimately burst. Potassium is very important in cellular biochemical reactions and energy metabolism; it participates in the synthesis of protein from amino acids in the cell.
Potassium also functions in carbohydrate metabolism; it is active in glycogen and glucose metabolism, converting glucose to glycogen that can be stored in the liver for future energy.
Potassium is important for normal growth and for building muscle. Though sodium is readily conserved by the body, there is no effective method for potassium conservation. Even when a potassium shortage exists, the kidneys continue to excrete it.
Because the human body relies on potassium balance for a regularly contracting heart and a healthy nervous system, it is essential to strive for this electrolyte's balance. In medicine, potassium is one of the most commonly prescribed minerals. It is also commonly measured in biochemical testing and is supplemented if it is low. Because potassium is crucial to cardiovascular and nerve functions and is lost in diuretic therapy for edema or hypertension, a prevalent American disease, it must be added as a dietary supplement frequently.
As stated before, the average American diet has reversed the natural high potassium-low sodium intake, and a shift back to this more healthful balance will help reduce some types of elevated blood pressure.
Supplementing potassium can be helpful in treating hypertension specifically caused by a hyper-response to excess sodium. In one study, 37 adults with mild hypertension participated in a crossover study. Patients received either 2. They were then crossed-over to receive a different treatment for another eight weeks and so on.

The results of the study demonstrated that potassium supplementation lowered systolic blood pressure from an average of 12 mm Hg and diastolic blood pressure an average of 16 mm Hg. Interestingly, the additional magnesium offered no further reduction in blood pressure.
Potassium supplementation may be especially useful in the treatment of high blood pressure in persons over the age of The elderly often do not fully respond to blood pressure-lowering drugs making the use of potassium supplement an exciting possibility.
After this relatively short treatment period the group getting the potassium experienced a drop of 12 mm Hg in systolic and 7 mm Hg in diastolic blood pressure. These results compare quite favorably to the reduction of blood pressure produced by drug therapy in the European Working Party on High Blood Pressure in Elderly Study.
The Role of Potassium and Sodium in Your Diet
Pharmacological preparations of potassium are commonly prescribed for many of these conditions. A 10 percent potassium chloride solution is often given, but its taste is unpleasant.
More easily used formulas are tablets that are swallowed or effervescent tablets. Time-release formulas such as Micro-K are also available.
Potassium chloride has occasionally been helpful in treating infant colic, some cases of allergies, and headaches.

During and after diarrhea, potassium replacement may be necessary, and many people feel better taking potassium during weight-loss programs. Fatigue or weakness, especially in the elderly, is often alleviated with supplemental potassium, along with magnesium.
Additional potassium may also be required for dehydration states after fluid losses and may be used to prevent or reduce hangover symptoms after alcohol consumption.
Elevations or depletions of this important mineral can cause problems and, in the extreme, even death. Maintaining consistent levels of potassium in the blood and cells is vital to body function. Even with high intakes of potassium, the kidneys will clear any excess, and blood levels will not be increased. A diet high in sodium increases the amount of calcium excreted in the urine. This loss is especially prominent when calcium intake is low, as it is for so many Americans.
Loss of calcium can contribute to osteoporosis, the age-related weakening of bones.

One way to combat the problem is by taking in more calcium from food or supplements. Getting more potassium, in the range of the recommended 4, mg a day, can also help. To be sure, there is more to bone health than sodium and potassium. Heredity, lack of exercise, hormone levels low testosterone in men, low estrogen in womenand a dearth of vitamin D and vitamin K can also weaken bones.
But it's good to know that a positive change made for your heart is doing good things elsewhere in the body. Food companies continue to blur the boundary between food and medicine.
Does Sodium Affect Potassium? | Healthy Eating | SF Gate
An early entry, a margarine-like spread called Benecol, contains sterol esters derived from vegetable oil or wood pulp that help lower cholesterol. In the body, the circulation of the electrolyte is not free.
Its existence remains confined only to the extracellular environment, in other words in the liquid where our cells, including blood plasma are liquid phase of blood. The sodium concentration of the various liquid compartments in our body influences the water volume retained in these compartments and therefore the total water volume in our body.
Sodium is essential to maintain the water distribution in the body or water balance and to maintain a stable level of blood pressure. Sodium pillar of the muscle function The sodium presence in the liquid compartments of the body goes beyond the water movement regulation.
Circumscribed on the surface of the cell membrane, where it ensures the proper transmission of the nervous influx through a complex mechanism of ion exchange, sodium allows muscle contraction.
