We sometimes feel very tired, we feel like we have no energy, our muscles are aching, our head hurts, don't we? We usually think that these are because we don't get enough rest, or because we have worked too hard. But the reason for these things may be something you probably don't even think about. That is the imbalance of electrolytes in our body. Today, we will talk about this simply and precisely.
What are these electrolytes?
Simply put, electrolytes are essential minerals in our bodies. When these combine with body fluids like blood and urine, they create a small electrical charge. Think of our body as a complex machine. So, for this machine to work properly, it needs electricity. Similarly, the electrical signals coming from these electrolytes are essential for many things in our body, such as the nervous system, muscles, and heart, to function properly.
We get these electrolytes from the food we eat and drink, sometimes from supplements, and our bodies also produce them.
The main types of electrolytes in our body and their functions
There are several main types of electrolytes in our body. Each of them has a specific role. Let's take a look at what they are and what happens to them.
| Electrolyte type | Role in the body |
|---|---|
| Sodium | It controls the amount of fluid in the body and helps with nerve and muscle function. |
| Potassium | Essential for the functioning of the heart, nerves, and muscles. It helps carry nutrients to cells and remove waste. |
| Calcium | It helps control blood pressure, constrict and dilate blood vessels, and is important for hormone and enzyme secretion and the nervous system. |
| Chloride | Helps maintain healthy levels of body fluids, blood pressure, and blood. |
| Magnesium | It helps with nerve and muscle function and is also needed for the development of healthy bones and teeth. |
| Phosphate | Supports the functioning of the skeletal system, nerves, and muscles. |
| Bicarbonate | It maintains the acid-base balance (pH balance) of the blood. It helps remove carbon dioxide, a waste product, from the body. |
What is an electrolyte imbalance?
An electrolyte imbalance is when one or more of the above minerals are too high or too low in the body. Organs like our kidneys and liver regulate these levels in the body. If this regulation is disrupted due to a medical condition or other reason, an imbalance occurs.
Simply put, everything should be in moderation. Just like adding a little more or less salt can change the taste of food.
There are two types of these imbalances:
1. Elevated electrolyte levels (Hyper-): The presence of more electrolytes in the body than necessary.
2. Electrolyte depletion (Hypo-): A decrease in the body's electrolyte levels beyond the required amount.
| Electrolyte type | Level rise (medical term) | Hypotension (medical term) |
|---|---|---|
| Sodium | Hypernatremia | Hyponatremia |
| Potassium | Hyperkalemia | Hypokalemia |
| Calcium | Hypercalcemia | Hypocalcemia |
| Magnesium | Hypermagnesemia | Hypomagnesemia |
Why does this happen? What are the risk factors?
There are many reasons why an electrolyte imbalance can occur. Infants, young children, and the elderly are at higher risk of this condition. However, it can occur in anyone of any age.
The main causes and risk factors are:
- Dehydration: Excessive loss of water and salts from the body. This can be caused by conditions such as excessive vomiting, diarrhea (diarrhea), excessive sweating (hyperhidrosis), or fever.
- Kidney disease: The kidneys control the amount of salt and fluid in the body. When the kidneys fail, this balance is lost.
- Liver disease: Liver conditions such as cirrhosis.
- Heart disease: Conditions such as high blood pressure and heart attack.
- Burns: Severe burns can cause a large amount of fluid to be lost from the body.
- Cancer and cancer treatments: This condition can be caused by some types of cancer and chemotherapy.
- Some medications: diuretics, laxatives), some antibiotics, and corticosteroids can also cause electrolyte levels to change.
- Overhydration: Even if you drink more water than necessary, electrolytes like sodium can become diluted and levels can decrease.
- Eating disorders.
How do I know if I have this condition? - Symptoms
If the electrolyte imbalance is mild, you may not have any symptoms. However, as the condition worsens, you may experience one or more of the following symptoms:
- Extreme tiredness and fatigue (Fatigue)
- Muscle cramps, spasms or weakness
- Nausea and vomiting
- Headaches
- Irregular or rapid heartbeat (Arrhythmia)
- Confusion and irritability
- Diarrhea or constipation
- Numbness or tingling in the hands and feet
Since these symptoms can also be signs of other diseases, it is very important to see a doctor immediately if one or more of them persist.
How does the doctor diagnose this and what are the treatments?
The main test to diagnose this is a blood test called an electrolyte panel . This can accurately measure the levels of key electrolytes, such as sodium and potassium, in your blood.
Treatment depends on which electrolyte imbalance you have and what is causing it.
- Minor imbalances: Minor dehydration can sometimes be treated with oral rehydration salts (ORS) or electrolyte-containing drinks, and adequate fluid intake. However, it is best to do this under the advice of your doctor .
- Medical treatment: If the condition is a little more serious, the doctor may prescribe the following treatments:
- IV fluids ( saline ): Rehydration of the body by giving saline (e.g., sodium chloride) through a vein.
- Medications and supplements: Pills or intravenous medications to restore depleted electrolytes.
- Hemodialysis: This treatment is used for severe imbalances caused by kidney failure.
The most important thing is to treat the underlying disease (e.g. kidney disease, diabetes) that is causing this condition. Otherwise, simply correcting electrolyte levels will not help.
Could this be serious? When to seek immediate medical attention
Yes. Electrolyte levels that are too high or too low can be life-threatening. This can lead to serious complications such as coma, seizures, and sudden cardiac arrest .
Therefore, if you or someone you know has the following symptoms, go to a hospital's Emergency Department (ETU) or see a doctor immediately.
- A clear change in heart rate (such as rapid, pounding, etc.)
- Unbearable fatigue
- Persistent vomiting or diarrhea
- Severe confusion or loss of consciousness
- Sudden severe muscle pain or numbness
Take-Home Message
- Electrolytes are minerals that are essential for the functioning of our body's nerves, muscles, and heart.
- These increases or decreases can cause symptoms such as fatigue, muscle twitching, and confusion.
- Dehydration, kidney disease, heart disease, and some medications can be the main causes of this condition.
- If you have symptoms, it is very important to see a doctor immediately and seek advice without self-treating.
- This condition can be diagnosed with a simple blood test, and can be completely cured with proper treatment depending on the cause.
👩🏽⚕️ Additional questions (FAQs)
💬 What is Electrolyte Imbalance?
The electricity that our nerves and heart use to function is carried by electrolytes like Sodium, Potassium, Calcium, and Magnesium dissolved in the blood! If these levels decrease or increase by even one milligram, the entire body system can collapse, the brain and heart can stop working, and the patient can fall into a coma/die (Fatal Arrhythmias), a very serious and fatal condition.
💬 What are the main causes of sudden loss of electrolytes/potassium/sodium in the body (Electrolyte Imbalance)?
The main and most common ones are 1) Severe Diarrhea and continuous Vomiting. This causes all the salts in the body to be lost along with water within a day (dehydration)! Also 2) Diuretics (water pills that cause excessive urination). 3) Kidney Failure (kidney failure) causes the body to retain toxins/salts instead of filtering them out. 4) Heatstroke.
💬 What are the most dangerous symptoms of electrolyte imbalance? When should you run to the doctor?
When the body lacks salt, 1) Muscle cramps/spasms occur, and limbs lose their strength. 2) Irregular heartbeat/arrhythmia occurs suddenly, causing chest tightness (in case of potassium problems). 3) Confusion, loss of consciousness, and sudden 'seizures' (in case of sodium problems). If these symptoms occur, you should go to an ICU immediately, as the heart may stop in a short time!
