What is the function of ADH (vasopressin) in regulating osmolarity in the blood?

Kidney and water. Hi. ADH (vasopressin) prevents the kidney from putting water out in the urine (a graded dose-response). If solutes in the blood are becoming too high a concentration, ADH (vasopressin) is secreted and makes the kidney put water from the kidney filtrate back into the blood, which dilutes out the solutes and brings down the osmolarity. Falling osmolarity suppresses ADH (vasopressin) secretion. The waltz goes on. Read more...

How would too much ADH (vasopressin) production increase blood pressure?

ADH (vasopressin) stands for. Anti diuretic hormone. The more fluid in the system, the higher the pressure will be. Read more...
ADH (vasopressin) Anti diuretic hormone (vasopressin) is produced by the gland in the brain called pituitary gland. It increases water absorption in the kidneys & increases peripheral vascular resistance , which leads to the increase in blood pressure. Read more...

How common is it to have a hypothalamic tumor resulting in excess ADH (vasopressin) and high blood pressure?

Extremely uncommon. There are some made-up "teaching materials" out there that talk about this. Excess ADH (vasopressin) is common in small-cell lung cancer but actually produces low sodium rather than high blood pressure since other hormones control body water volume by removing sodium in the urine. If you've been told you have such a tumor, get a second opinion. Real hypothalamic tumors seldom make hormones. Read more...
