Dehydration occurs when large amounts of water are lost from the body by means of diarrhea, vomiting, excessive sweating, etc. One can identify that the body is dehydrated from the symptoms like dry mouth, muscle cramps, decreased urine output, lightheadedness, etc.
Dehydration can result in increased heart rate and blood pressure. It can also lead to poor cognitive performance as the mood, energy levels, and ability to focus are disrupted.
Option (a) is the correct option. Hematocrit measures the percentage of the red blood cells that make up the given volume of blood. When the fluid content of the blood drops due to dehydration, there is an increase in the number of red blood cells per volume of the fluid.
Consumption of more fluids can bring back the hematocrit values to normal. Dizziness, vision problems, headaches, etc. are experienced with high hematocrit levels in the blood.
