The water-electrolyte system in our body is in charge of the conveyance of essential substances and enables the accurate excretion of metabolic byproducts. Potassium is one of its components and also fulfills numerous other significant roles in our body. In the subsequent sections of this article, you will learn about the sources of this element in food and the implications of its deficiency.
Common knowledge about potassium
Potassium is an extremely important micro-component that forms the electrolyte economy in the body. This signifies that this constituent is present in every part of our body – inside the cells, in the intercellular spaces, as well as in blood and body fluids. This compound is present in most food products, with the largest amount in avocados, bananas, figs, apples, dried carrots, tomatoes, raisins, and potatoes. The optimal concentration of potassium in blood ranges from 3.5 to 5 mmol/l.
Is that genuinely the responsibility of potassium in the body?
As previously mentioned, potassium, along with other elements, forms a group of electrolytes responsible for transporting essential substances to most internal organs and cells, for regulating our metabolism by eliminating unsuitable and harmful products of metabolism or affecting thermoregulation. Potassium is essential for the proper functioning of many important processes in the body. It is this element that triggers the body's secretion of fat, the conditions that contribute to proper nerve-muscle conduction, improving muscle contraction, or enhancing the entire nervous system. Maintaining the correct level of potassium in the blood has a significant impact on the oxygenation of the brain, strengthening the processes of logical thinking, improving concentration, effectively regulating the work of the kidneys and blood pressure. It is also worth mentioning that the systematic supply of potassium significantly accelerates the process of burning fat.
Potassium deficiency in the body and its consequences: Hypokalemia
A low potassium content in the body can lead to visible symptoms. The most common symptoms of potassium deficiency are edema and swelling in the lower and upper limbs, involuntary muscle contractions that may sometimes transition into a state of muscle twitching, high blood pressure, accelerated heart rate, and impaired nervous system function. The causes of hypokalemia include insufficient potassium intake in the diet, loss of potassium due to vomiting, diarrhea, or long-term use of diuretic medications, as well as the process of transmineralization, in which potassium is shifted into cells through intensive insulin therapy or correction of acidosis.
Provision of Dosed Quantities
As previously noted, the proper potassium level in the blood should be 3.5-5 mmol/l, and daily intake should range from 2-3 g, either through food or supplements. Is it possible to overdose on potassium? Yes, it is possible when the potassium level in the blood exceeds 5.5 mmol/l. Hyperkalemia is a condition characterized by an elevated blood potassium level. This can lead to reduced absorption of certain medications and decreased response to them. It can also lead to an accelerated heart rate and increased blood pressure, which can eventually lead to hypertension. It is also worth noting that an elevated potassium level in the body can indicate other diseases and disorders, such as metabolic acidosis, renal failure, uremia, crush syndrome, Addison's disease, hemolysis, or dehydration.
