Potassium is one of the important minerals present in our diet, which plays a key role in the functioning of the body. Potassium deficiency and excess can have harmful effects on health. In this article we will discuss the importance of potassium in the body, the symptoms of deficiency and excess, and how to supplement it in the diet.

Potassium – function in the body

Potassium is necessary for the proper functioning of many biological processes in the body. Its main functions are:

• Regulation of blood pressure: Potassium helps control blood pressure by influencing the balance of sodium and water in the body.
• Muscle and nerve function: Potassium is necessary for the proper functioning of muscles, including the heart, and the transmission of nerve impulses.
• Maintaining acid-base balance: Potassium helps maintain the appropriate pH level in the body, which is important for health.

Potassium deficiency

A deficiency of potassium in the diet can lead to many health problems, including:

• Muscle weakness
• Muscle cramps
• Heart rhythm problems
• Hypertension
• Weakened immune system

To avoid potassium deficiency, it is worth eating products rich in this mineral, such as bananas, oranges, potatoes, spinach and dried fruits.

Excess potassium

Excess potassium in the body is rare, but may occur in people with abnormal kidney function or with excessive use of potassium supplements. Symptoms of excess potassium may include:

• Nausea
• Muscle weakness
• Heart arythmia

If excess potassium is suspected, it is important to consult a doctor who will take appropriate diagnostic and therapeutic steps.

Supplementing potassium

To maintain the proper level of potassium in the body, it is worth providing it with a varied diet, rich in fruits, vegetables and whole grain products. Bananas are especially recommended as they are an excellent source of potassium. You can also consider potassium supplementation, but it’s always worth consulting your doctor before starting.
