What should be the rate of potassium in the blood in women

25.05.2022 0 By admin
Potassium is an important element of the intracellular space involved in metabolic reactions, the exchange of salts and water. It helps the work of the myocardium and protein synthesis. The rate of potassium in the blood in women is 3.5 – 5.5 mmol / l. Deviations from these figures indicate a pathology that requires treatment.

Functions of potassium

Potassium is found in the body in the intracellular space. It improves the conduction of nerve impulses, muscle contractility. The element contributes to the normal functioning of the kidneys and intestines.

blood potassium levels in women

The norm of blood potassium in women is 3.5 – 5.5 mmol / l. It varies slightly with age.

In addition to these functions, there are others:

  1. Regulates osmotic pressure inside cellular structures.
  2. Improves water and electrolyte balance.
  3. Participates in the synthesis of protein molecules.
  4. Normalizes acid-base balance.

Potassium is also essential for the functioning of the heart muscle.

The substance is involved in the transport of oxygen to the striated, cardiac muscles, brain tissues. Against the background of an adequate level of the trace element, blood pressure normalizes. Potassium enhances immune defenses.

The trace element does not have a depot for storage, so it must be supplied regularly with food. If the diet is not rational, and does not have foods containing potassium, a deficient state develops.

When is it indicated to take a potassium test?

There are diseases that require control of potassium in the blood:

  • pathology of the urinary system;
  • insufficient function of the adrenal glands;
  • hypertension;
  • heart pathologies: ischemic disease, angina pectoris, myocardial infarction, vascular atherosclerosis, thrombosis and others;
  • the use of diuretics, cardiac glycosides;
  • performing hemodialysis.

All these conditions require the appointment of blood biochemistry for potassium and other indicators. The concentration of potassium is also checked in athletes, patients with malnutrition.

Norms of potassium in the blood in women and in the urine

To see the level of potassium, blood biochemistry is prescribed. Sometimes they take urine for research. In it, the amount of potassium should be 25-125 mmol / day.

The normal amount of potassium for men and women in a blood test is 3.5-5.5 mmol / l. But for women of different age groups, the amount of potassium is slightly different.

What is the norm for women in accordance with the age group in mol / l:

  • 18-50 years of age – 3.4-5.6;
  • after 50 years of age – 3.2-4.8;
  • over 60 years of age – 3.0-4.5;
  • pregnant patients – 3.4-5.3.

These data must be taken into account when assessing blood biochemistry for potassium. If the indicator is less than 3.0-3.4, this indicates hypokalemia. At potassium above 5.6, hyperkalemia is set.

Preparing and taking a blood test

The day before delivery, salty, smoked, spicy dishes are excluded from the diet. A biochemical blood test for potassium is taken from a vein in the morning: 8:00-10:00. Before the analysis, you can not eat anything. Brushing your teeth is also not recommended.

Preparation for the study is mandatory, since the results change at the slightest violation of the doctor’s recommendations. In addition to non-compliance with nutrition, other reasons that distort the results of the study are possible:

  • prolonged pressure on the hand with a tourniquet, namely more than 2-3 minutes;
  • collection of material immediately after the use of potassium preparations;
  • violation of the storage of material;
  • damage to the venous wall during sampling.

These factors are taken into account when collecting blood.

High levels of potassium may appear due to hereditary predisposition. In this case, the doctor conducts an examination to exclude all diseases, and also prescribes a re-sampling of the material.

Together with potassium, they can watch the concentration of other elements, namely sodium. These 2 elements together participate in water-salt metabolism. It is important to know the concentration of calcium in some diseases. It is able to reduce the amount of potassium.

With pathologies of the kidneys, the amount of urea is checked, which shows how the kidneys cope with their function.

An equally important element is creatinine clearance. It shows the degree of filtration of blood in the kidneys. Depending on the type of pathology, other elements are added to the biochemical blood test.

What is the most common cause of potassium deficiency?

A lack of potassium provokes a large number of factors. The main ones are:

  • irrational nutrition;
  • change in potassium metabolism;
  • diseases of the urinary, digestive, respiratory systems;
  • taking laxatives and diuretics and herbs, glucocorticosteroid hormones;
  • stressful situations, depressive states, neuroses.

Also, a lack of potassium is caused by an excess of cesium, rubidium, thallium and other elements.

In women with hypokalemia, chronic impotence, exhaustion, muscle weakness are noted. Over time, immune protection decreases, adrenal dysfunction occurs, which is manifested by false urge to urinate. The patient’s blood pressure increases, anemia, interruptions in the work of the heart, heart attacks, panic attacks are detected.

There is a deterioration in the condition of hair and nails, gastritis, ulcerative lesions of the digestive tract appear. In women, erosion of the cervix occurs. Prolonged and severe hypokalemia leads to infertility.

Excess potassium: causes and symptoms

A dangerous condition is hyperkalemia. If a person receives 6 g of potassium per day, this will cause poisoning. If 14 g of potassium enters the body, a lethal outcome is possible. The concentration of the trace element increases under the following conditions:

  • the use of dietary supplements;
  • metabolic change;
  • the appearance of burn wounds, injuries, crash syndrome;
  • decrease in insulin concentration;
  • dysfunction of the urinary system.
  • the occurrence of diseases of the sympathoadrenal system.

These are the main causes of hyperkalemia.

In women with hyperkalemia at the initial stage, irritability, aggression, hyperexcitation, and anxiety occur. Then there is weakness in the muscles, vegetative-vascular dystonia. There are interruptions in the work of the heart in the form of arrhythmias, dysfunction of the digestive tract is noted.

Potassium Dose Calculation

For an adult woman, a daily dose of potassium is 2000 mg. To calculate the dosage for patients over 25-30 years old, use the formula: 2000 mg + age in years.

The calculation looks like this:

  • 2000 mg is the daily requirement of potassium;
  • age in years – 45 years;
  • calculation – 2000 + 45 = 2045 mg.

This calculation shows that a 45-year-old woman needs 2045 mg of potassium per day. This rate is suitable for light to moderate activity. If the patient plays sports, she needs 2500-5000 mg.

Correction of hyperkalemia and hypokalemia

If there are signs of hyper- or hypokalemia, you should immediately consult a doctor. The doctor will conduct an examination, prescribe general blood and urine tests, biochemistry. To reduce the concentration of potassium in the bloodstream, the following measures are taken:

  1. Cancel drugs that increase the amount of potassium: dietary supplements, vitamin complexes, potassium iodide and others.
  2. Inject drugs that reduce the concentration of potassium intravenously.
  3. Do injections of glucose or insulin.
  4. Carry out hemodialysis.
  5. Give diuretics.

In addition to these activities, special diet therapy is prescribed. Spinach, legumes, dark chocolate, cabbage, sea fish, kiwi, bananas, grapes, oranges, tangerines are removed from the diet.

level

To adjust the level of potassium, diet therapy and special drugs are prescribed.

With hypokalemia, the diet is first adjusted. Prunes, dried apricots, beans, peas, raisins, almonds, hazelnuts, seaweed, lentils, peanuts, pine nuts, potatoes, cashews, walnuts, bananas, dates, persimmons, figs, peaches are introduced into it. Potassium is found in milk drinks, cottage cheese, and fish.

If nutrition does not work, potassium preparations are prescribed. It is better to take capsules so as not to damage the gastric mucosa. With the ineffectiveness of oral agents, intravenous administration of drugs containing potassium is prescribed. Most commonly used tablets and capsules.

Potassium is of great importance for women, as it allows you to maintain the vital activity of the body, and also supports reproductive function. Severe potassium deficiency provokes infertility. To avoid hyper- and hypokalemia, it is worth adhering to proper nutrition, treating serious illnesses in time.
