To help mild dehydration, increase your fluid intake by drinking water or electrolyte-rich beverages like sports drinks or coconut water. Consuming foods with high water content, such as fruits and vegetables, can also be beneficial. Additionally, avoid excessive caffeine and alcohol, as they can contribute to dehydration. If symptoms persist, consider consulting a healthcare professional.
Mild dehydration is common and usually caused by not drinking enough fluids throughout the day. In children, diarrhoea is a common cause. There are many causes of dehydration, the most common are diarrhoea, vomiting, sweating, excessive urination and fever or burns.
Mild to moderate dehydration without vomiting can be managed with oral hydration. If the dehydration is severe or if there is frequent vomiting there is no other option but to administer fluids intravenously.

The first symptom of dehydration should be thirst but as we have noted above this response is often blunted. Symptoms generally progress to more dire manifestations as the need for water becomes more extreme. Someone who is chronically dehydrated at a point somewhere between normal and the mild dehydration we discuss below may even be able to develop a tolerance for that state so that it becomes the "new normal" for them. Suffice to say that any level of dehydration will lead to long term consequences if left unaddressed.There are some symptoms for dehydration:ThirstReduced Appetite,Skin FlushingDark colored UrineDry MouthFatigueMild headacheChillsDizziness

Moderate dehydration can begin to have deleterious effects after 48 hrs, moderate to moderately severe can be fatal in 7-10 days. Severe dehydration can cause multi-system failure in 24 -72 hrs, depending on your hydration level and general health at the time immediatetly preceding a catastrophic event.

The time it takes to feel better after dehydration can vary depending on the severity of the condition and how promptly treatment is initiated. Mild dehydration can often be resolved within a few hours to a day with proper fluid intake, while more severe cases may take several days to fully recover. It's important to rehydrate gradually and monitor symptoms, as severe dehydration may require medical intervention. Always consult a healthcare provider if symptoms persist or worsen.
