When you sweat, are very tired, or have a stomachache, you've probably heard adults say, "You're dehydrated, drink an orange." Or maybe you just feel tired, lethargic, or dizzy. Many of these things can be caused by an imbalance in the electrolytes in our bodies. So what are these electrolytes? Why are they so important to our bodies? Let's talk about them in detail and simply today.
So, what exactly are Electrolytes?
Simply put, electrolytes are substances that can develop a small electrical charge when dissolved in water. Think of it like a battery. These are mineral salts that can take on a positive (+) or negative (-) charge.
Now look, an adult's body is 60% water . That means every cell in our body, every fluid, contains these electrolytes. Without them, we wouldn't be able to do many things, such as regulate chemical processes in our body, balance the amount of fluid inside and outside our cells, make our muscles work, and transmit nerve messages.
We get these electrolytes from the food we eat and drink. For example, oranges, bananas, and salt contain a lot of them. Our kidneys act as our body's filter. If the body has more electrolytes than it needs, the kidneys excrete the excess in urine. Electrolytes are also lost from our bodies when we sweat.
The most important thing is to have the right balance of these electrolytes in the body. Too much of it can cause problems, and too little can cause problems.
Let's understand some words we often hear.
You may come across these words when talking to a doctor or reading a report. It is very important to know their simple meaning.
| Word | Simple meaning |
|---|---|
| Hyper- (hyper) | This word is used to say that something is "too much" . For example: Hypernatremia (increased sodium). |
| Hypo- (hypo) | This word is used to describe a "lack" of something. For example: Hypokalemia (low potassium). |
| Ion | A molecule with an electrical charge. |
| pH value | A measure of whether a liquid is acidic or alkaline/basic. The normal pH of our blood should be between 7.36 and 7.44. |
The main electrolytes in our body and their functions
There are several types of electrolytes in our body. Each of them has a specific function. Let's take a look at the main ones, what happens if they increase, and what happens if they decrease, in this table.
| The electrolyte | Symptoms that occur if there is an increase (Hyper-) | Symptoms of deficiency (Hypo-) |
|---|---|---|
| Sodium (Sodium / Na+) - Essential for fluid balance in cells and nutrient absorption. | ||
| Hypernatremia | Confusion, behavioral changes, loss of muscle control, seizures, coma. | Confusion, irritability, nausea and vomiting, seizures, coma. |
| Potassium (Potassium / K+) - Very important for heart function and the nervous system. | ||
| Hyperkalemia | Lifelessness, inability to move muscles, and irregular heartbeats (arrhythmias). | Muscle pain and weakness, excessive thirst and frequent urination, fainting, and irregular heartbeat. |
| Calcium (Calcium / Ca2+) - Essential not only for bones and teeth, but also for muscles, nerves, and the heart. | ||
| Hypercalcemia | Headache, extreme fatigue, kidney stones, stomach pain, constipation, irregular heartbeat. | Confusion, muscle spasms, and tightness in the throat muscles, making it difficult to speak or breathe. |
| Magnesium (Magnesium / Mg2+) - Helps produce energy, brain and muscle function. | ||
| Hypermagnesemia | Changes in heart rate, difficulty breathing, and even cardiac arrest can occur. | Muscle weakness, muscle cramps, heart rhythm irregularities. |
| Chloride (Cl-) - Helps regulate the body's fluid balance and pH. | ||
| Hyperchloremia | Increased acidity in the blood (acidosis), nausea, vomiting, extreme fatigue, rapid breathing. | Increased alkalinity in the blood (alkalosis), brain fog, heart rhythm irregularities, muscle spasms. |
| Phosphate (PO43−) - A building block of DNA, helps cells produce energy. | ||
| Hyperphosphatemia | Often causes low calcium levels. May cause excessive itching. | Muscle weakness. Severe cases, muscle breakdown (rhabdomyolysis), seizures, difficulty breathing. |
| Bicarbonate (Bicarbonate / HCO3−) - Helps control the pH (acidity/alkalinity) of the blood. | ||
| Alkalosis (increased) | Brain fog, lethargy, heart palpitations, muscle spasms. | Acidosis (deficiency) - nausea, vomiting, extreme tiredness, rapid and deep breathing. |
How do you know if there is an electrolyte problem?
If you have the symptoms mentioned above, your doctor may suspect an electrolyte imbalance. To confirm this, they will usually do a few blood and urine tests .
You may have heard of these.
- Basic Metabolic Panel (BMP): This can give a rough idea of the main electrolytes (such as sodium, potassium, chloride) and kidney function.
- Comprehensive Metabolic Panel (CMP): This is a bit more detailed than the BMP. It provides information on other things like calcium and liver enzymes.
- Electrolyte Panel: This only directly looks at electrolyte levels.
If these basic tests show any abnormalities, your doctor may order more specific tests to pinpoint the cause.
How do I understand the values in the report?
The test report you receive will include a "reference range" with your value. If your value is within that range, it is considered normal.
But remember, sometimes your values may be slightly out of the normal range, but it may not be a big problem. And sometimes, even if your values are within the normal range, if you have symptoms, it could be a different problem.
This is like spinning a plate on a stick. Balance is the key. Our bodies are always trying to maintain this balance. Therefore, only your doctor can give you the best interpretation of what your test results mean. So talk to your doctor about it.
When should I see a doctor?
Symptoms of electrolyte imbalance can often seem very normal, such as fatigue and dizziness. But if you have any of these symptoms, you should definitely see a doctor.
- If you feel persistent fatigue or weakness .
- If your heartbeat feels fast or irregular .
- If you have confusion, agitation, or memory loss .
- If you experience frequent muscle pain, muscle spasms, or cramps .
- If you have severe nausea, vomiting, or diarrhea .
If you have these symptoms, don't ignore them. Getting treatment on time can prevent serious complications.
Take-Home Message
- Electrolytes are a type of mineral that is essential for the proper functioning of our body's nerves, muscles, heart, and brain.
- Balance is the most important thing. Both excess and deficiency can lead to disease.
- We get these from a balanced diet and the fluids we drink. Fruits, vegetables, and oranges are especially good.
- During times like excessive sweating, vomiting, or diarrhea, a large amount of electrolytes can be lost from the body. It is important to consume a drink like Jeevani at such times.
- If you have symptoms such as persistent fatigue, muscle pain, or changes in heart rate, do not ignore it and consult your doctor for advice .
