Final answer:
When metabolic heat and dehydration occur, electrolyte loss can result. Dehydration refers to water loss from the body without proper replacement, which can lead to electrolyte imbalance. Excessive sweating can also lead to electrolyte loss.
Step-by-step explanation:
When metabolic heat is produced in the body and dehydration occurs, it can result in electrolyte loss. Dehydration refers to the loss of water from the body without adequate replacement, which can lead to electrolyte imbalance. Prolonged physical activity without sufficient water intake, heat exposure, excessive weight loss, vomiting, diarrhea, and other factors can cause dehydration. The decrease in blood volume during dehydration causes water from cells to move into the blood, resulting in cell shrinkage and various symptoms.
Electrolyte loss can occur due to excessive sweating, particularly in hot conditions or during physical activity. Sweat glands secrete fluid onto the skin, and as the fluid evaporates, heat is lost from the body. Along with the sweat, electrolytes are also lost, which can lead to an imbalance. Symptoms of electrolyte deficiency can include nausea, fatigue, dizziness, muscle weakness, and increased heart rate.
