How can ADH cause an increase in blood pressure?

ADH

1. ADH is anti-diuretic hormone.
2. It is a hormone whose concentration increases when there is a deficiency of body fluid and dehydration.
3. A higher concentration of ADH causes constriction of arterioles leading to vasoconstriction.
4. As a result of vasoconstriction, the blood pressure increase.
5. Intake of water helps to lower the concentration of ADH and reduce blood pressure.
