Dehydration occurs when the fluid intake of the body is far less than the amount of fluid lost by the body. In most of the cases, signs of dehydration might be a symptom of a serious underlying condition like hyperhidrosis and diarrhea and polyuria. Also if you suffer from a chronic illness like kidney or heart disorders, you are at high risk of developing this condition. Also, infants and children can develop this medical condition as a symptom of diarrhea.
The signs of mild dehydration depend on the intensity of the condition and you might experience symptoms of frequent dry mouth, headache, dizziness and a significant reduction in urine output. In the case of severe dehydration, it is possible to encounter the symptoms of fever, no urination, low blood pressure, rapid breathing and heartbeat along with excessive thirst and excessive dryness of the skin and mouth. In some cases, the initial signs of dehydration can increase to significant levels and produce immense discomfort.
If not diagnosed at the earliest, dehydration can lead to further complications. The possible effects of severe dehydration include heat injury, failure of kidneys and in extreme cases, falling into a coma and subsequent death. You must check up with your doctor as soon as possible in order to avoid complications. Consult a general physician in such episodes.
