Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced . A high ADH level causes the body to produce less urine. A low level results in greater urine production.
What happens when ADH is too high?
Excess ADH. When there's too much ADH in your blood, syndrome of inappropriate ADH (SIADH) may be the cause. If the condition is acute, you may have a headache, nausea, or vomiting . In severe cases, coma and convulsions can occur.
What happens when ADH is decreased?
Diabetes insipidus is caused by a lack of antidiuretic hormone (ADH), also called vasopressin, which prevents dehydration, or the kidney's inability to respond to ADH. ADH enables the kidneys to retain water in the body. The hormone is produced in a region of the brain called the hypothalamus.
What triggers ADH?
ADH is normally released by the pituitary in response to sensors that detect an increase in blood osmolality (number of dissolved particles in the blood) or decrease in blood volume. The kidneys respond to ADH by conserving water and producing urine that is more concentrated.
What is the normal function of ADH?
Antidiuretic hormone (ADH) helps regulate the amount of water in your body . It works to control the amount of water your kidneys reabsorb as they filter out waste from your blood. This hormone is also called arginine vasopressin (AVP).
How do you stop ADH?
In all cases, the first step is to limit fluid intake. This helps prevent excess fluid from building up in the body. Your provider will tell you what your total daily fluid intake should be. Medicines may be needed to block the effects of ADH on the kidneys so that excess water is excreted by the kidneys.
How can I lower my ADH naturally?

- Avoiding too much light at night. ...
- Managing stress. ...
- Exercising. ...
- Avoiding sugars. ...

- Eating lots of fiber. ...
- Eating plenty of fatty fish.
What happens to ADH when you drink a lot of water?
More ADH will be released, which results in water being reabsorbed and small volume of concentrated urine will be produced . If a person has consumed a large volume of water and has not lost much water by sweating, then too much water might be detected in the blood plasma by the hypothalamus.
What is a normal ADH level?
Normal Results
Normal values for ADH can range from 1 to 5 pg/mL (0.9 to 4.6 pmol/L) . Normal value ranges may vary slightly among different laboratories.
How do you treat low ADH levels?
Central diabetes insipidus.
Typically, this form is treated with a synthetic hormone called desmopressin (DDAVP, Nocdurna) . This medication replaces the missing anti-diuretic hormone (ADH) and decreases urination. You can take desmopressin in a tablet, as a nasal spray or by injection.
How do you increase ADH at night?
What to do about it: Practice good sleep habits so you can fall into your REM cycle, increase your ADH production and NOT have to get up in the middle of the night to pee! If you chug a 32 ounces of water an hour before bed then inevitably you may have to get up to pee.
How do you test for low ADH?
ADH is not a standard blood test, so many hospitals and doctors' offices may have to send the blood sample to a more extensive laboratory. As a result, it may take several days to get the results. A doctor will typically order an ADH blood test along with a physical examination, electrolyte tests, and urine tests .
How does ADH work on kidneys?
Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of “water channels” or aquaporins into the membranes of kidney tubules . These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
How does ADH affect sodium levels?
As noted above, ADH plays a role in lowering osmolarity (reducing sodium concentration) by increasing water reabsorption in the kidneys , thus helping to dilute bodily fluids. To prevent osmolarity from decreasing below normal, the kidneys also have a regulated mechanism for reabsorbing sodium in the distal nephron.
How does ADH control urine concentration?
ADH increases the permeability to water of the distal convoluted tubule and collecting duct , which are normally impermeable to water. This effect causes increased water reabsorption and retention and decreases the volume of urine produced relative to its ion content.
How do you treat ADH?
The first line of treatment is to limit fluid intake to avoid further buildup . Medications may include those that can reduce fluid retention, such as furosemide (Lasix), and those that can inhibit ADH, like demeclocycline.
