If you don't drink water for 3 days, you can become dehydrated, which means your body loses more fluids than you take in. Dehydration can happen more easily if you have diabetes, have been sick or have diarrhea, have been in the sun too long, have drunk too much alcohol, sweat a lot after exercising, have a high temperature, or take medicines that make you pee more. Symptoms of dehydration in adults and children include feeling thirsty, dark yellow, strong-smelling pee, peeing less often than usual, feeling dizzy or lightheaded, and feeling tired. You can also have a dry mouth, lips, and tongue, and sunken eyes. If dehydration is not treated, it can get worse and become a serious problem. You should drink fluids if you have symptoms of dehydration. If you're being sick or have been sick, you may find it hard to drink, so start with small sips and then gradually drink more. Urgent advice is needed if you're feeling unusually tired, confused and disorientated, or have dark yellow pee or are peeing less than normal.

What Happens If You Don’t Drink Enough Water
Whatever you do, make sure you get in those six to eight glasses, otherwise dehydration could cause a whole host of problems.
Persistent headaches.
One of the first things you might notice when you’re dehydrated is a throbbing headache.
The good news is if dehydration is the cause, it should go away shortly after you drink a large glass of water.
Sluggish bowel function.
There are water receptors in the colon, and they pull water from the body to make the stools softer, says Dr. Moghaddam.
If you don’t get enough water, hard stools and constipation could be common side effects, along with abdominal pain and cramps.
Dull skin.
Dehydration shows up on your face in the form of dry, ashy skin that seems less radiant, plump and elastic.
Fatigue.
If you’re not replenishing your fluid intake, your energy levels could plummet and you could experience fatigue and brain fog.
Weight gain.
Sometimes people mistake thirst for hunger and they eat more, but really they just need to drink more, says Dr. Moghaddam.
Sometimes if you have a glass of water, the hunger cues will go away.
Dry mouth.
If you’re not getting enough water, you can have dry mucous membranes—i.e., a lack of saliva.
This can make it difficult to talk, swallow, and even breathe.
Luckily, this can easily be solved by drinking water.

You won’t live long without consuming a healthy amount of water. It’s only possible to survive without water for a matter of days. Depending on certain factors, you may be susceptible to dehydration even sooner. Scientists believe the number, in most cases, is closer to about 3 days. Without enough water, systems in your body will change. All the cells in your body require water. Without enough water, they shrink and begin to lose their function. Your brain will signal your body to urinate less. This will occur through your kidneys. They rely on an adequate water intake to function properly. Without enough water, the kidneys use more energy and wear on tissue. Your kidneys need to function adequately to flush out waste from your blood. Eventually, your kidneys will cease to function without adequate water intake. Other organs and systems in your body will cease to function without water.

You might be thirsty, and your mouth might feel dry or sticky. You won’t pee very often -- under 4 times a day. When you do go, there may not be much pee, and it’ll be dark or have a strong smell. You may feel dizzy or lightheaded, especially when you stand up, and you may pass out. As it gets worse, your thirst cranks up. Your breathing and heart rate may be faster than normal. You can overheat, and you might feel confused or cranky. When dehydration is mild or even moderate, you can often kick it with plenty of water. But if you have severe diarrhea or are throwing up, an oral rehydration solution might help. When your water levels get too low, you can’t tackle dehydration on your own. You’ll need to be treated at a hospital.
