Is your potassium level low? Let's learn about Hypokalemia in simple terms

Do you sometimes feel very tired and lifeless for no reason? Or do you have muscle cramps and tingling in your legs even when you are just standing? We often forget about these things, thinking that they are normal. But sometimes there may be a health problem behind these small symptoms that we cannot see. One such problem is the decrease in the level of potassium, an essential mineral in our body. In medicine, we call this condition hypokalemia . Don't be afraid when you hear the name. This is a very common condition. Today, we will talk about this very simply and in a way that you can understand.

Simply put, what is hypokalemia?

Think of our body as a complex machine powered by a battery. This machine needs electricity to function properly. Similarly, potassium is essential for the cells, nerves, muscles, and especially our heart to function properly.

Potassium is an electrolyte . That is, it is a mineral that, when combined with fluids like water in our bodies, creates a small electrical charge. These electrical signals are what help our nerves send messages, muscles contract (squeeze), and our heart beat at the right rhythm.

Normally, the potassium level in the blood of a healthy adult should be between 3.5 and 5.2 millimoles per liter (mmol/L). If this level drops below 3.5 for any reason, we call it hypokalemia. If this value drops below 3.0, we consider it a slightly more serious condition.

Our bodies get the potassium they need from the food we eat. Our kidneys filter out excess potassium through urine, maintaining the right level for our bodies. But problems begin when this balance is disrupted.

Why does our body lose potassium? What are the reasons?

There is not one reason for low potassium, but many reasons can affect it. In most cases, the main reason for this is excessive potassium excretion through the digestive tract (intestines). But there are other reasons in addition to that. Let's see what these reasons are clearly with the help of a table.

What are the symptoms of low potassium?

Symptoms can vary depending on how low your potassium levels are. Sometimes, when your potassium levels are slightly low, you may not experience any symptoms. However, as the levels get lower, symptoms begin to appear.

When potassium levels are slightly low (Mild Hypokalemia)

Common symptoms that can be seen at this time are:

• Constipation: Constipation can occur due to impaired bowel function.
• Heart palpitations: You may feel your heart beating faster or faster, or your rhythm may change.
• Fatigue: Feeling tired no matter how much sleep you get.
• Muscle weakness and spasms: The limbs feel lifeless, and sometimes the muscles may twitch as if a ball is being thrown.
• Tingling and numbness: You may feel a tingling sensation in your limbs.

When potassium levels are significantly low (Severe Hypokalemia)

This is a situation that requires some caution. At this time, the symptoms mentioned above may become more severe. New symptoms may also appear.

• Muscle twitches and cramps: Frequent muscle twitches and pain.
• Paralysis: In very severe cases, muscle function may stop completely, resulting in a condition called paralysis.
• Hypotension: Low blood pressure can cause dizziness or lightheadedness when standing up.
• Serious heart rhythm abnormalities (Arrhythmias): Abnormal heart rhythms can occur that can be life-threatening due to disruption of the heart's electrical activity.
• Frequent urination (Polyuria) and excessive thirst (Polydipsia): Frequent urination occurs because the kidneys are unable to concentrate urine, which leads to excessive thirst.

How do you find this, Doctor?

When you go to see your doctor, he or she will ask you about your symptoms, examine you, and order several tests to confirm the diagnosis and find the cause of your hypokalemia.

1. Blood test: This is the most important test. A sample of your blood is taken and the exact level of potassium is measured. It also checks kidney function and the balance of other electrolytes in the body.

2. Urine test: If the cause of low potassium is unclear, a urine test can be done to measure the amount of potassium in your urine. This can help determine whether your kidneys are excreting too much potassium or if there is another cause.

3. ECG (Electrocardiogram) test: Since low potassium levels directly affect the electrical activity of the heart, the doctor may also decide to take an ECG to check for any abnormalities in the heartbeat.

What are the treatments for this?

Treatment depends on how low your potassium level is and the severity of your symptoms.

• If the condition is not too serious: If your potassium level is slightly low, your doctor will prescribe potassium supplements to take by mouth. He or she will also advise you to eat more potassium-rich foods.
• If the condition is severe: However, if your potassium level is very low, your heart rate is affected, or if oral medications cannot bring your level back to normal, you may need to be hospitalized. There, you may need to be given potassium intravenously along with saline . This can quickly and safely bring your potassium level back to normal.

What can we do to prevent potassium deficiency?

The best thing to do is to prevent this condition from occurring. The simplest and best thing we can do for that is to add potassium-rich foods to our daily diet.

Here are some foods rich in potassium:

• Fruit: Banana, avocado, orange, tangerine, pomegranate, raisins
• Vegetables: Potatoes, sweet potatoes, tomatoes, spinach, kale, broccoli, beetroot
• Legumes: beans, chickpeas, lentils, soy
• Other: Milk and milk products (yogurt), fish (especially salmon, trout), peanuts

This need can be met by regularly adding a banana, an orange, or a gourd salad to our regular meals.

Also, if you have persistent vomiting or diarrhea for more than two days, do not stay at home and see a doctor immediately. This condition can occur when a large amount of potassium is lost from the body along with fluid. If you seek treatment early, you can prevent such complications.
