What is Dehydration

Your body needs a certain amount of water every day in order to function properly. When you are dehydrated it means you have not consumed enough fluid for the body to maintain its normal can happen at any age.

Symptoms of Dehydration

There is no one symptom that fits all.

Babies and Toddlers

  • No wet nappies for three hours
  • No saliva in the mouth
  • When crying there are no tears
  • Sunken eyes and cheeks
  • Babies, Sunken soft spot on top of skull (the fontanell)
  • Listlessness or irritability


  • Having a high temperature
  • Dizziness
  • Fatigue, extreme tiredness
  • Feeling Confused
  • Less frequent urination
  • Dark-colored urine
  • Strong smelling pee
  • Feeling Extremely thirsty
  • Cramp
  • Headache

Some Of The Causes

Dehydration is not only caused by not drinking enough water, there are many other things that can cause it :

  • Diarrhea or vomiting. Severe, acute diarrhea which is, diarrhea that comes on very suddenly and violently — can cause a tremendous loss of water and electrolytes in a short period of time. If you have vomiting along with diarrhea, you lose even more fluids and minerals.
  • High Fever. In general, the higher your fever, the more dehydrated you will  become. The problem gets worse if you have a fever over 38 as well as diarrhea and vomiting.
  • Excessive sweating. You can lose a lot of water when you sweat. If you do lots of different activity’s and don’t replace fluids as you go, you can become dehydrated. Hot or humid weather increases the amount you sweat and the amount of fluid you lose. In hot conditions you should consume at least 2 liters of water or 8 glasses.
  • Increased urination. This may be due to undiagnosed or uncontrolled diabetes. Certain medications, such as diuretics and some blood pressure medications, also can lead to dehydration, generally because they cause you to urinate more.
  • Certain medications can also make you dehydrated because they make you pee more, always read the side affects to be more aware.
  • Alcohol, drinking to much alcohol can also make you dehydrated.this happens because you urinate more.
  • Burns, if you burn yourself you can become dehydrated.

Those most At Risk

  • Babies and children. The most at risk people to experience severe diarrhea and vomiting are babies and children. One problem that occurs is not being able to communicate that they are thirsty.
  • Older adults. As you get older, your body’s fluid reserve becomes smaller, this means it’s harder to conserve water and your thirst sense becomes less reliable. These problems are made worse by chronic illnesses such as diabetes and dementia, and by the use of certain medications. Older adults also have difficulty with moving around and  that makes it harder to get water for themselves.
  • People who work or exercise outside.  Are prone to getting sun stroke. When it’s hot and humid, your risk of dehydration and heat illness increases. That’s because when the air is humid, sweat can’t evaporate efficiently and cool you down as quickly as it normally does, this can then lead to an increased body temperature and the need for more water to be consumed more often.
  • People with chronic illnesses. Having uncontrolled or untreated diabetes puts you at a very high risk of dehydration. Kidney disease also increases the risk, as do medications that increase urination. Even having a simple cold or sore throat makes you more liable to dehydration because you’re less likely to feel like eating or drinking when you are feeling unwell.


Major Problems

  • Heat injury. If you don’t drink enough fluids when you’re exercising vigorously and perspiring heavily, you may end up with a heat injury, ranging in severity from mild heat cramps to heat exhaustion or potentially life-threatening heatstroke.
  • Urinary and kidney problems. Prolonged or repeated episodes of dehydration can cause severe urinary infections, kidney stones and even kidney failure.
  • Seizures. Electrolytes — such as potassium and sodium — help carry electrical signals from cell to cell. If your electrolytes are out of balance, the normal electrical messages can become mixed up, which can lead to involuntary muscle contractions and sometimes to a loss of consciousness.
  • Low blood volume shock (hypovolemic shock). This is one of the most serious, and sometimes life-threatening, complications of dehydration. It occurs when low blood volume causes a drop in blood pressure and a drop in the amount of oxygen in your body.

When To See A Doctor

  • If you have had diarrhea for 24 hours or more
  • If you feel very irritable or disoriented and much sleepier or less active than usual
  • Can’t keep anything down
  • If there is blood in your stools
  • If your stools are a black color


How to get Tested and Diagnosed 

  1. Gently pinch the skin on your arm or stomach between your finger and thumb to form a “tent” shape.
  2. Then Let Go of the skin.
  3. Check to see if it goes back to its normal position in one to three seconds.
  4. If the skin is slow to return to normal, you could be dehydrated.
  5. A blood test may also be performed.


The Best Ways To Prevent Dehydration

Eat fruits and vegetables that contain lots of water. Drink plenty of water every day. If you live in a warm climate, do regular physical exercise, work outside, have diarrhea or episodes of vomiting. Ensure you keep up the fluids little and often to prevent becoming dehydrated. The best thing to drink is water, anything decaffeinated, milk or squash. Do not drink anything fizzy or containing caffeine. 

My Final Thoughts

Not drinking enough fluid can have very serious health consequences. The first thing a hospital checks for is dehydration because it’s something an awful lot of people suffer from. Drinking a minimum of 2 liters of fluid a day is recommended and more if you are somewhere very warm.

Take great care of yourself because you are very worth It.

  1. I’ve been quite concerned about sufficient hydration because it affects the skin so much. I notice that on days I don’t drink enough (because of travelling or just forgetting about it) my facial skin shows more fine lines and isn’t so plump. 

    I also have a low blood pressure and think that if I don’t drink enough it might make me more dizzy when changing my body position. So I try to control my drinking routine and be more aware of it. I don’t know if I had experienced real dehydration but I might have, when I think back at the few times I fainted when the weather was too hot.

    Thank you for this article, it’s a great summary of dehydration causes and symptoms.
