Too much sweating THESE warning signs could mean dangerous electrolyte loss
Sweating helps to cool the body down and occurs naturally in cold weather, during exercise or physical activity. Sometimes, however, the amount of sweating can cause loss of minerals in the body, known as electrolytes. These minerals are important for the proper functioning of the body and the lack of them would have a negative effect on the health of the body.
What are electrolytes and why are they important?
According to Dr. M. Sheetal Kumar,Consultant Physician & Diabetologist, Yashoda Hospitals, Hyderabad, "The electrolytes present are sodium, potassium, calcium, magnesium and chloride. Their importance in managing fluid balance, helping muscle function, transmission of nerve signals and regulation of heart rhythm cannot be denied. A heavy sweat loss over an extended period of time can cause an imbalance of lost fluids and minerals from the body."
Muscle cramps may signal electrolyte loss
A frequent symptom of electrolyte depleting is muscle cramps. Heavy sweating can cause cramping in the legs, arms or stomach in many people. This is because muscle cells require adequate amounts of the two minerals, sodium and potassium, in order to function. When the electrolytes are depleted, muscles can get tight and painful.
Dr. M. Sheetal says that another warning sign is to feel weak or tired. Electrolytes are required for energy production by cells and to maintain normal cellular activity. When too much mineral salts are lost via the sweat, you may feel very tired, weak or dizzy, even while you're resting.
Headaches and dizziness from dehydration
Dehydration and loss of electrolytes may also lead to headache. When you sweat too much, you'll lose plenty of water in your body, and that can create problems with your circulation, resulting in headaches and dizziness. At times patients can even be confused or unable to focus their attention.
Irregular heartbeat can be a serious warning sign
Another significant symptom to keep an eye out for is an irregular heartbeat. Proper heart function requires potassium, calcium and magnesium. If not corrected, electrolyte imbalance may be serious and lead to faulty heart rhythm.

Nausea and vomiting after heavy sweating
According to WHO, Individuals that sweat profusely will also have symptoms of nausea or vomiting. This is particularly likely when through high-intensity exercise, exposure to temperature or during an illness of heat and sweat. When the minerals are rapidly depleted from the body, balancing is difficult.
Who is more at risk of electrolyte imbalance?
Some people may be more prone to electrolyte imbalance. Athletes, outdoor workers, older adults or those residing in very hot climates can sweat a considerable amount on a daily basis. Those who have diarrhea, vomiting or fever can also have electrolyte imbalance.
How to replenish lost electrolytes naturally?
Enjoy fluids all day long to avoid losing electrolytes. Hydration is important, and in cases of profuse sweating there might also be a need for fluids that have electrolytes. Oral rehydration solutions, sports drinks or coconut water can be used to replenish the minerals lost. A potassium-rich diet with foods like bananas, oranges, spinach, nuts, and yogurt, may also help balance electrolytes.
