We all lose fluids on a daily basis - through urination, breathing and sweating. However, when the human body loses more fluids than the amounts of fluids that are drunk throughout the day, dehydration occurs. Dehydration occurs due to the facts that the human body has little to no fluids which are vital for the normal functions to be achieved on a daily basis. The most apparent reason for dehydration merely is not drinking enough water - an action that most people forget about when they are too busy or when they have no access to safe drinking water. But dehydration can occur when you are suffering from a fever, diarrhea, and vomiting, or use certain medications that increase the risk of dehydration.
Exercising vigorously without drinking appropriate amounts of water is another cause of dehydration. Infections of the lungs and bladder have been reported to cause dehydration as well. Dehydration must be treated right away because of the many risks that it pose such as hypovolemic shock, seizures, kidney problems, etc. The most effective treatment involves fluids and electrolytes replacement.
Dehydration Symptom #1: Dark Colored Urine
The first sign of dehydration is dark yellow, concentrated urine. Due to the lack of water and oxygen in the body, the blood pressure and blood flow reduce as a result of what the kidneys store more water than usual instead of trying to expel it from the body. This on the other hand results in dark colored, concentrated urine. The urine can get dark yellow and even brownish color in some cases.
