8 Most Detrimental Health Effects of Dehydration

Updated: Apr 4, 2019



Up to 60 percent of the human adult body is made up of water — water we tend to take for granted until we lose enough of it to experience symptoms of dehydration.

Dehydration is a condition in which the body has lost more fluid and electrolytes such as -sodium, potassium, and chloride- than it took in. This condition impairs body's ability to regulate temperature and function normally.

Common causes of dehydration include but are not limited to:

  • FEVER - is a body temperature that’s higher than normal. A short-term increase in body temperature can help the body fight off illness. However, a severe fever can be a symptom of a serious condition that requires immediate medical attention.



  • DIARRHEA - is characterized by loose, watery stools or a frequent need to have a bowel movement. Diarrhea can be a result of a viral or bacterial infection or food poisoning.


  • EXCESSIVE SWEATING - We lose water when we sweat. If we do vigorous activity and don't replace fluids as we go along, we can become dehydrated


  • VOMITING - can be a one-time event linked to something that doesn’t agree with our stomach or recurrent - caused by underlying medical conditions. Frequent vomiting may lead to dehydration, which can be deadly if left untreated.


  • PRESCRIPTION MEDICATIONS - due to the fact that many prescription medications are also diuretics, meaning they make us urinate more often. The increased passing of urine depletes our water supply and leads to dehydration.. Blood pressure medications are commonly associated with this problem.



  • STRESS - can cause dehydration, and dehydration can cause stress - sounds like a vicious cycle. The key solution is to get enough fluids!


  • ALCOHOL CONSUMPTION - due to the fact that alcohol is a diuretic, just like some of those prescription medications.


  • DIABETES - High blood sugar can lead to dehydration by causing frequent urination which is the body's way of getting rid of extra sugar. A large amount of water goes out with that urine, causing our body to dry out.
