Adipsia, also known as hypodipsia, is a symptom of inappropriately decreased or absent feelings of thirst. It involves an increased osmolality or concentration of solute in the urine, which stimulates secretion of antidiuretic hormone (ADH) from the hypothalamus to the kidneys.
Not being thirsty at times during the day is normal, if the body does not need more fluid. But if you have a sudden change in the need for fluids, you should see your health care provider right away.
For example, diabetes, physical exhaustion, and mental disorders may all prevent you from feeling thirsty when your body needs water. If you are diagnosed with any of these chronic conditions or another disease, your doctor or physician should inform you about the potential for dehydration without feeling thirst.
Thirst is one way your body alerts you to drink more fluid. However, sometimes you can become dehydrated without feeling thirsty. Other possible dehydration symptoms include: A dry or sticky mouth or a swollen tongue.
Thirst is normally just the brain's way of warning that you're dehydrated because you're not drinking enough fluid. But excessive and persistent thirst (known as polydipsia) could be a sign of an underlying problem such as diabetes.
It's also likely that you'll feel thirsty all the time and have a "dry" feeling that's always present, no matter how much water you drink. If you need to pee regularly and always feel thirsty, your sleeping patterns and daily activities may be disrupted.

The causes of a body not absorbing water include diabetes insipidus, chronic kidney disease, adrenal insufficiency, excessive sweating, diarrhea or vomiting, and medications such as diuretics or laxatives.
The symptoms of dehydrated kidneys can include dark urine, decreased urine output, dizziness or lightheadedness, fatigue, headache, dry mouth and throat, thirst, muscle cramps, and nausea and vomiting.
Anxiety has a tendency to make people feel full when they're not, or to cause a loss in appetite. Many people with anxiety do not drink enough water, and that "excessive thirst" is really just an indication of dehydration.
People with ADHD often struggle to focus, but when engaged in something we're interested in, we can easily veer to the opposite end of the spectrum: hyperfocus. We tend to get so wrapped up in what we're doing that we forget literally everything else—including our basic needs, like drinking enough water!
Water makes up 60% of a person's body weight. The maximum time an individual can go without water is about a week.
Some of the most common presenting symptoms of dehydration include but are not limited to fatigue, thirst, dry skin and lips, dark urine or decreased urine output, headaches, muscle cramps, lightheadedness, dizziness, syncope, orthostatic hypotension, and palpitations.
Chugging large quantities of water isn't hydrating you any more than if you sip it slowly. It can seem like you're being proactive by gulping down a large amount of water before beginning some extraneous exercise.
Changes in the brain that are indicative of adipsia include those of hyperpnea, muscle weakness, insomnia, lethargy, and convulsions (although uncommon except in extreme cases of incredibly rapid rehydration).
As dehydration progresses, the body redirects blood to the working muscles and away from the skin, impairing your body's ability to diffuse heat. The increase in internal heat then results in muscle cramps, light-headedness, and fatigue. If you have chronic fatigue syndrome, you will identify with this symptom.
Transparent and lacking in color
Transparent, colorless urine could also be a sign of some other health disorders, including diabetes and kidney disease, or from taking diuretic medication.
Dehydration can lead to severe complications, such as seizures, swelling of the brain, kidney failure, shock, coma and even death. Signs and symptoms of dehydration include: Headache. Dizziness or lightheadedness.
