Symptoms like lightheadedness, muscle cramps, and general weakness are indications that the body is failing to compensate for dehydration. Nausea and vomiting are particularly bad because they can cause the situation to get worse.
feeling unusually tired (lethargic) or confused, and you think you may be dehydrated. dizziness when you stand up that doesn't go away after a few seconds. not passing urine for eight hours.
peeing less often than usual. feeling dizzy or lightheaded. feeling tired. a dry mouth, lips and tongue.
Dehydration can lead to severe complications, such as seizures, swelling of the brain, kidney failure, shock, coma and even death.
Signs of dehydration include: Headache, delirium, confusion. Tiredness (fatigue). Dizziness, weakness, light-headedness.
According to a recent study from the Journal of Strength and Conditioning Research, your body can alleviate mild dehydration in 45 minutes with 20.3 oz (600ml) of water.
Mild, moderate, and severe dehydration have similar treatments and warning signs but at varying levels. For more mild or moderate cases of dehydration, expect your body to feel better after just a few hours, but full rehydration won't happen until about three days later.
In general, however, it usually takes about two hours for your body to rehydrate fully after drinking a significant amount of water. As for how you should rehydrate, water is the best choice. Sports drinks, such as Gatorade, can be helpful for athletes who need to replenish electrolytes.

You might have an electrolyte imbalance: Electrolyte imbalances are one of the most common reasons you might feel dehydrated even after drinking tons of water: “Sometimes if we drink a lot of water but we don't take in enough fruits and vegetables, our electrolytes—sodium, potassium, magnesium, chloride, etc.
The researchers found that while water — both still and sparkling — does a pretty good job of quickly hydrating the body, beverages with a little bit of sugar, fat or protein do an even better job of keeping us hydrated for longer.
You can quickly check for dehydration at home. Pinch the skin over the back of the hand, on the abdomen, or over the front of the chest under the collarbone. This will show skin turgor. Mild dehydration will cause the skin to be slightly slow in its return to normal.
The person loses consciousness at any time. There is any other change in the person's alertness (for example, confusion or seizures). The person has a fever over 102°F (38.8°C). You notice symptoms of heatstroke (such as rapid pulse or rapid breathing).
If dehydration is not treated through increased consumption of water, or in some cases, the consumption of electrolytes, the dehydration can last indefinitely.
About a half hour to an hour after drinking Hydralyte I did notice that I felt a little more energy and felt overall good!
Best Overall: Gatorade
The levels of electrolytes (sodium and potassium) are moderate and sensible with 160 mg of sodium and 45mg of potassium per 12 fluid ounce serving. You can also find Gatorade varieties with higher sodium, zero sugar or no calories depending on your needs.
Dehydration can also affect your colon, which is the last segment of your digestive tract. Your colon absorbs more than a liter of fluid each day and this fluid helps stool move through your colon. Without this fluid, stool hardens to cause constipation.
Dehydration causes the spinal discs to lose water, resulting in back pain. When those discs aren't hydrated as they should be, your spine ends up suffering the consequences by taking on the full shock of your movements, which leads to pain. Here is what you need to know.
Going to Sleep Dehydrated Can Cause Cramping
If you haven't had enough water during the day or before bed, you may experience cramping like this while you sleep, especially in your legs. This can be very painful, waking you up and keeping you from getting a good night's sleep.
Stinking Breath and Body Odor
If your body is dehydrated, you are unable to release these toxins (bacteria), which when accumulated leads to an unpleasant body odor, especially in the armpits, feet, and groin area.
Fruits and vegetables can help with hydration [a banana is 74% water!] and provide healthful nutrients such as vitamins, minerals, fiber and protein. So for elite athletes – or those just trying to stay fit – a diet with plenty of fruits and vegetables, including bananas, is important for performing at your best!
Intravenous (IV) fluids and IV medication -- including some that contain electrolytes or medications that help normalize electrolyte levels -- are often used. Other IV medications may need to be used to treat underlying causes of dehydration (for example, IV antibiotics for dehydration caused by infection).
