Potassium: properties and functions

A person weighing 70 kg contains about 140 g. potassium. The 7% is in bone tissue. 0.5% in the interstitial fluid and lymph. Most potassium is ionized inside the cells. Its concentration is highest in the digestive fluids than in plasma.

Properties of potassium
This mineral salt is linked to sodium and chlorine. Its main functions are:
* Potassium regulates the water content of the cells. Thanks to the so-called sodium pump / potassium the body keeps potassium in the cells and sodium outside.
* With sodium and potassium chloride regulates osmotic pressure and is part of acid / base. If there is acidosis in the body potassium leaves the cell. If the opposite occurs alkalosis.
* Potassium Increases muscle excitability, especially the heart, nervous system and muscles.
* Essential for the proper functioning of the myocardium.
* Potassium is part of the construction of proteins: when proteins are destroyed (catabolism) potassium out of cells, when created (anabolism), potassium goes.
* Involved in the synthesis of glycogen.

Potassium is a healing of the body, is an activator of the liver, gives elasticity to tissues, causing the muscles are flexible, creates the grace, beauty and good disposition. Potassium is highly alkaline.

Sources of potassium
Generally, all low-sodium foods rich in potassium. Fresh vegetables, fresh fruits (especially the skins). All integral. The main sources for obtaining it are: Potato peelings soup, dandelion, dill, sage, dried olives, parsley, vinegar or apple cider, cranberry and the like, peaches, the prunes, coconut, dried yeast, nuts, chocolate, gooseberries, kale, figs, and almonds. Potassium is a specific food for the heart and found in foods and bitter herbs majorities. The apple and celery juice provides potassium.

Symptoms of potassium deficiency (hypokalemia)

Their needs are small: between 2000-3500 mg / day. With a balanced diet is readily available.

However it may be a shortfall in the following cases:
* Vomiting, diarrhea, loss by the kidneys (diuretic use saline, certain nephritis).
* Abusing laxatives.
* Takes prolonged cortisone.
* By the action of insulin in case of diabetes.
* In the adrenal gland disorders.

This translates into the following:
* Muscle weakness, paralysis. Distension of the stomach, intestine and sluggish gallbladder.
* Heart failure: dilatation of the heart, decreased blood pressure (hypotension), arrhythmia.
* Acid-Base Imbalance: the cells become dehydrated (edema).

Symptoms of excess potassium (hyperkalemia)
Although much rarer than those above, may be a case of hyperkalemia in renal or adrenal insufficiency (Addison's disease). Symptoms of excess potassium in these cases are usually Cardiovascular slowing heart rate, arrhythmias, blood pressure drop, even you can reach the cardiac arrest.
