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 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
Low sodium: ADH (vasopressin) is anti-diuretic hormone which causes your body to retain free water. When you have too much of it, your body retains too much free water and "dilutes" out the sodium content in your blood which will cause the level to drop. Low sodium in the blood can be very detrimental to your health. ...Read moreSee 1 more doctor answer
Seek Med help if OD: Dear htreference, An OD of ADH can result in excess water retention that can cause electrolyte abnormalities, especially low sodium (hyponatremia) that can be dangerous. Symptoms of too much ADH can include, but not limited to headache, drowsiness, weakness, pale skin, nausea, and stomach pain.

Vasopressin,: also known as antidiuretic hormone/ADH, is a "pituitary" hormone which acts to retain water and constrict blood vessels. It increases water reabsorption in the kidney's collecting ducts. Decreased release due to alcohol intoxication or tumor leads to increased blood sodium/excessive urination/thirst. Excess vasopressin leads to low sodium. A number of problems cause inappropriate ADH-tumors, drugs ...Read moreSee 1 more doctor answer
Holds onto water: The posterior (back) part of the pituitary gland in the brain contains the cells that produce oxytocin (that stimulates uterine contractions in labor) and ADH (anti-diuretic hormone), which regulates retention of water by the body. ADH is also called vasopressin because it makes some blood vessels constrict (tighten). ...Read more
Depends on Diagnosis: Pitressin, or vasopressin, is a potent man-made form of a hormone called "anti-diuretic hormone" that is normally secreted by the pituitary gland. In the body, vasopressin acts on the kidneys and blood vessels. It is rarely used except in diabetes insipidus, or during some surgical procedures. There are many contraindications to its use so you should discuss this with your physician in detail. ...Read more
What happens if you were stranded in the desert, would you expect your body's production of vasopressin to increase?
Bingo!: Yes, correct. The regulation of vasopressin (ADH) involves both sensors for volume (an extrinsic variable) and solute concentration of blood (an intrinsic variable). As you sweat and lose more water than salt, your blood concentration of solute (called osmolality or osm) goes up...a potent stimulator of ADH secretion. This happens to the person in the desert to conserve water (endocrine regulation ...Read more
Genetics: Inborn differences among individuals results in a broad range of every type of human characteristic. Hormone production/responsiveness is no different. Some have more; some have less; if it's a lot less, it is viewed as a "deficiency". There may be additional factors -- related to sleep habits, stress, meds, intake of alcohol & other food/beverages, etc., but genetics is probably the main factor. ...Read more
