Importance and Role of Electrolytes in Human Body

(Dr Waseem Razaq, )

An electrolyte is a medium containing ions that is electrically conducting through the movement of those ions, but not conducting electrons. This includes most soluble salts, acids, and bases dissolved in a polar solvent, such as water. Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the solvent. Solid-state electrolytes also exist. In medicine and sometimes in chemistry, electrolytes have a natural positive or negative electrical charge when dissolved in water. They help your body regulate chemical reactions, maintain the balance between fluids inside and outside your cells, and more. They’re also a key way to diagnose a wide range of medical conditions and diseases. Electrolytes are very much important for human body because they help:
• Balance the amount of water in our body
• Balance our body's acid/base (pH) level
• Move nutrients into our cells
• Move wastes out of our cells
• Make sure that our nerves, muscles, the heart, and the brain work properly

As human body is about 60% water, which means nearly every fluid and cell in human body contains electrolytes. They help regulate chemical reactions, maintain the balance between fluids inside and outside cells in the body, and more. You get electrolytes or their components from what you eat and drink. Your kidneys filter excess electrolytes out of your body and into urine. You also lose electrolytes when you sweat. Sodium, calcium, potassium, chloride, phosphate, bicarbonate and magnesium are all electrolytes. You get them from the foods we eat and the fluids you drink. The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in, should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (over hydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance.

There are several key elements that your body needs to maintain normal electrolyte levels. The following are the major elements, marked as positive (+) or negative (-):
1. Sodium (+): Sodium is the most abundant electrolyte ion found in the body. Sodium helps your cells to maintain the right balance of fluid and to absorb nutrients. Hypernatremia (too much sodium) can cause confusion or behavior changes, unusually strong reflexes and loss of muscle control, seizures and coma. Hypernatremia (too much sodium) might cause confusion or behavior changes, unusually strong reflexes and loss of muscle control, seizures and coma.
2. Chloride (-): Chloride (the name for a chlorine ion) is the second-most abundant ion in the body. It’s also a key part of how your cells maintain their internal and external balance of fluid. It also plays a role in maintaining the body’s natural pH balance. Hyperchloremia (too much chloride) causes acidosis, which is when your blood’s acidity is too high. It results in nausea, vomiting and fatigue, as well as rapid, deeper breathing and confusion. This usually happens in connection with too much or too little potassium. Hypochloremia (not enough chloride) causes your blood to become more alkaline, a condition called alkalosis. It usually happens with hyponatremia or vomiting. Symptoms of alkalosis are apathy, confusion, arrhythmias and muscle twitching or loss of control.
3. Calcium (+): Calcium is a key element in your body, besides building strong bones and teeth it is also used to control your muscles, transmit signals in your nerves, manage your heart rhythm and more. Having too much calcium in your blood (Hypercalcemia) or too little calcium in your blood (Hypocalcemia) can cause a wide range of symptoms across different systems in your body.
4. Magnesium (+): Magnesium helps your cells as they turn nutrients into energy. Brain and muscles rely heavily on magnesium to do their job. Hypermagnesemia (too much magnesium) causes heart rhythm changes and arrhythmias, weakened reflexes, decreased ability to breathe and cardiac arrest. Hypomagnesemia (not enough magnesium) causes muscle weakness, twitching and loss of control, heart arrhythmias. This commonly happens in connection with calcium and potassium deficiencies.
5. Potassium (+): Potassium is used by cells alongside sodium. When a sodium ion enters a cell, a potassium ion leaves, and vice versa. Potassium is also especially critical to your heart function. Too much (Hyperkalemia) or too little (Hypokalemia) can cause serious heart problems.
6. Phosphate (-): Phosphate is a phosphorous-based molecule that’s a key part of transporting chemical compounds and molecules outside your cells. It helps your cells metabolize nutrients, and it’s also a key part of molecules called nucleotides, which are the building blocks that make up your DNA. Hyperphosphatemia (too much phosphate) causes you to experience hypocalcemia because your body tries to use calcium as a substitute for phosphorus. Hypophosphatemia (not enough phosphate) causes usually muscle weakness as a early symptom. As it gets worse, more severe symptoms occur. They include breakdown of muscle tissue, which can cause severe kidney damage), seizures, reduced heart function and trouble breathing (caused by muscle weakness).
7. Bicarbonate (-): Some of carbon dioxide made in body gets recycled into bicarbonate, which your body uses to keep your blood pH levels normal Too much bicarbonate causes alkalosis when your blood to become more alkaline and too little bicarbonate causes acidosis which is when your blood’s acidity is too high.
Best and Healthy Dietary Sources of Electrolytes: The main food sources of electrolytes are fruits and vegetables. However, in the modern era diet, a common source of sodium and chloride is table salt.

Below are some foods that provide electrolytes

1. Sodium: Pickled foods, cheese and table salt.
2. Chloride: Table salt.
3. Potassium: Fruits and vegetables like bananas, avocado and sweet potato.
4. Magnesium: Seeds and nuts.
5. Calcium: Dairy products, fortified dairy alternatives and green leafy vegetables.
6. Phosphate: A variety of foods naturally contain phosphorus, and the richest sources are dairy, red meat, poultry, seafood, legumes, and nuts, in the body, almost all phosphorus is combined with oxygen, forming phosphate
7. Bicarbonate: Bicarbonate are naturally produced in your body, so you don’t need to worry about including them in your diet.
How to Keep Electrolytes in Balance: The best way to keep electrolytes balanced in your body is by taking enough amount of water and having healthy diet by including especially fruits, vegetables and nuts and seeds in the diet along with dairy and meat products. But in severe cases electrolytes imbalance needs properly diagnoses and treatment and it should be done through health professional.
