Mr. Grimaldi was previously diagnosed as having a posterior pituitary tumor that causes hypersecretion of ADH. He comes to the clinic regularly to have his blood pressure checked. Would you expect his blood pressure to be chronically elevated or depressed? Why?
Hi thanks for asking question. According to your question you want to know effect of ADH on blood pressure. ADH is called desmopressin. It has property of water retention in tubules and constriction of blood vessels with increase arterial resistance. So obviously it will raise blood pressure along with other symptoms like headache, vommiting and in severe case convulsion. So if he is suffering from ADH secreting tumor then blood pressure will rise. I hope I have solved your query.
