Can your blood pressure be high if you are dehydrated?
Hypertension- High blood pressure is common in people who are chronically dehydrated. When the body’s cells lack water, the brain sends a signal to the pituitary glad to secrete vasopressin, a chemical that causes constriction of the blood vessels. This causes blood pressure to increase which leads to hypertension.
Can dehydration cause high diastolic blood pressure?
Dehydration causes the blood to become thicker or viscous due to the reduced water content in the blood. Dehydration causes the kidney to release renin. This results in sodium and water retention in the body to correct the low fluid volume. This response, if constant, can cause blood pressure to be high.
How does dehydration affect blood pressure and heart rate?
Without enough fluids, your blood becomes thicker and moves more slowly through arteries and veins. This can cause an increase in blood pressure, particularly if you have high blood pressure or heart disease. The added strain on your heart can also lead to an increased risk of heart problems including hypertension.
