decreased concentration of solutes in the blood
The hormone that stimulates thirst is called antidiuretic hormone (ADH), also known as vasopressin. It is released by the pituitary gland in response to dehydration or high concentrations of solutes in the blood, signaling the body to conserve water and increase fluid intake.
The body normally loses less than 1% of its water at any one time. An increase in the osmotic pressure of ECF (extracellular fluid) due to water loss stimulates osmoreceptors in the thirst center (in hypothalamus) and the hypothalamic activity triggers thirst and the person seeks water.
Your body maintains fluid balance through various mechanisms such as hormone regulation (like antidiuretic hormone), electrolyte balance, and kidney function. The kidneys play a key role in regulating fluid balance by adjusting the amount of water and electrolytes excreted in urine. Additionally, the body's thirst mechanism helps signal when more fluids are needed to maintain proper hydration.
Thirst is part of a negative feedback mechanism. When the proper levels of water are not present in the body, a sensor detects the imbalance. The brain sent sends a signal to tell the body to obtain water/fluids to remain to a homestatic level of water. Once fluids are obtaind, the body can retain the water and levels will increase. Homeostatis is then reached as the response decreases.
Diabetes, both type 1 and type 2, can cause excessive thirst and urination. This is due to the body's inability to properly regulate blood sugar levels, which results in increased urination to remove excess glucose from the body, leading to dehydration and increased thirst.

The major stimulus for the thirst mechanism is dehydration, which is when there is a decrease in fluid volume within the body. When the body detects dehydration, it signals the brain to activate the thirst mechanism, prompting the individual to drink fluids to restore proper hydration levels.
electrolyte balance
Yes, ADH (antidiuretic hormone) stimulates the sensation of thirst. When ADH levels increase in response to dehydration or high blood osmolarity, it triggers the sensation of thirst to encourage drinking and help restore fluid balance in the body.
The body's thirst mechanism is primarily located in the hypothalamus, a region of the brain that regulates various bodily functions including thirst and hydration. When the body's fluid levels drop, sensors in the hypothalamus detect this change and signal the body to feel thirsty to encourage fluid intake.
When a person is dehydrated, their thirst mechanism shuts off. This makes them feel like they are not even thirsty.
The major stimulus for the thirst mechanism is an increase in the concentration of salts and other solutes in the blood, detected by osmoreceptors in the brain. When blood osmolality rises above a certain threshold, signals are sent to the brain to trigger the sensation of thirst, prompting us to drink water and restore fluid balance in the body.

no it does not. it is a survival mechanism, you can drink your pee twice before it is toxic if you are dying of thirst.
