Question

how would dehydration affect patients' blood pressure? His plasma sodium concentration? His cell volume?

Answer 1

ANSWER :-

Dehydration as we know is the loss of water from the body. A dehydration patients have a problem of high blood pressure. If a person is slightly or more dehydrated, the Heart of the person work harder to pump the blood, that increase the heart rate and cause an irregular heartbeat or palpitations. Dehydration thickens the blood and make the blood vessels walls to construct, that cause hypertension or high blood pressure and strain the heart.

In dehydration patients, the concentration of sodium in plasma is high. Loss of water from the body increases the level of sodium chloride or salt in blood this problem of dehydrationdehydration called as hypernatremia. Hypernatremia involves dehydration, that cause many problems like lack of drinking enough fluids, kidney dysfunctional, diarrhea and diuretics.

Dehydration in a patient cause volume depletion. As the large volume of water lost from the body by vomitting or diarrhea causing depletion of cell volume like intracellular and extracelluar fluid volume decreases. The water from inside the cell moves to the bloodstream to maintain the needed amount of blood(blood volume) and also the blood pressure. So, when dehydration continues, tissues of the body begins to dry out, and cells begins to shrivel and malfunction.
