Understanding Dehydration
_happens when your body loses more water than you drink. The correct answer is d. dehydration. Dehydration occurs when there is a loss of water from the body without adequate replacement, leading to a reduced body water content. This can be due to a variety of factors such as prolonged physical activity, excessive heat exposure, illness that leads to vomiting or diarrhea, or certain medical conditions that affect water retention. During dehydration, the blood volume decreases, triggering the need for the body to compensate by moving water from within cells into the bloodstream, which in turn causes cells to shrink. Symptoms of dehydration can include thirst, dizziness, fainting, headaches, low blood pressure, fatigue, and in severe cases, loss of consciousness and even death.
Contrary to dehydration, hyponatremia involves a lower-than-normal concentration of sodium in the blood, usually due to excess water diluting body sodium levels.
