ADH works to reabsorb water from the lumen of the collecting ducts in the kidneys back into the interstitial space. As a result, high levels of ADH will result in higher concentrations of aquaporin-2 on the luminal membrane, allowing for H2O reabsorption in the otherwise-H2O-impermeable collecting ducts. As a result, the urine will be more highly concentrated due to the loss of water (back into the blood), reaching an osmolarity of around 1400 mOsm maximum.
In dehydration, ADH levels are high (enables the body to retain more water) and in over-hydration, ADH levels are low (no need for the body to retain water, hence increased micturition)

What are effects of over hydration and dehydration?
Over hydration will dilute the body's chemical balance. Dehydration will cause organ damage. Both states are to be avoided if you wish to live!

Why do levels of human growth hormone rise during adolescence?
because cabbages will take over the world :)
Can over hydration cause creatinine levels to be low for a drug test?
Yes, absolutely. That's why they check creatinine levels. The drug tests rely on certain cutoff concentration levels to provide a positive result and therefore overhydrating is an easy way to test negative. Though you may test negative AND dilute, in which case they may make you test again (or not, or fire you, or not).
Why does my muscle mass fluctuate and what factors contribute to these fluctuations?
Muscle mass fluctuates due to a variety of factors such as diet, exercise, hydration levels, and genetics. Changes in these factors can lead to increases or decreases in muscle mass over time.
What is a serious complication of over hydration when using IV fluids?
pulmonary edema
