Frequently Asked Questions

Dehydration

» What is Dehydration?

The body requires the correct balance of fluid and electrolytes (salts and minerals) to maintain everyday functions and preserve health. Internally, the body has special mechanisms which help to keep this balance in check. However, the loss of fluid and electrolytes through urine, sweat, vomit, diarrhea and other bodily fluids can upset this balance, and in some cases, a person may experience dehydration. The signs and symptoms of mild to moderate dehydration will occur when as little as 2% of the body weight is lost through fluid.

» What are the signs and symptoms of dehydration?

There are many different signs and symptoms of moderate dehydration. These include:

  • Increased thirst
  • Fatigue / Lethargy
  • Dizziness
  • Headaches
  • Dark or decreased urine output
  • Sticky or dry mouth
  • Loss of skin elasticity
  • Irritability

Try to recognize the common signs and symptoms of dehydration. If and when they occur, start using an oral rehydration solution, Hydralyte, as soon as possible.

Remember that dehydration can be of particular concern for the elderly and for young children.

» How does dehydration occur?

Dehydration occurs when there is the loss of fluid and electrolytes from the body at a faster rate than they are being replaced. Fluid and electrolyte loss can occur through urine, sweat, vomit and diarrhea.

» Does excessive sweating cause dehydration?

The loss of fluid and electrolytes through sweat can lead to dehydration in some circumstances.
When excessive sweating is caused by vigorous or prolonged physical activity (i.e. during endurance sport or exercise), dehydration may occur. This can happen if adequate fluid consumption (with an appropriate hydration fluid) does not occur.

In cases where excessive sweating is due to a fever, there is also a chance of dehydration if adequate hydration is not achieved.

» Is it possible to be dehydrated and not realize? If so how (aside from thirst) would you know?

Sometimes we just forget to eat or drink enough, and dehydration can happen without realizing. Often thirst is one of the later symptoms of dehydration to appear. By the time we get thirsty, we can already be moderately dehydrated. Some earlier signs of dehydration are sticky or dryness of the mouth, decreased urine output, and dark yellow colored urine.

» Can dehydration cause diarrhea?

Diarrhea is a common cause of moderate dehydration. Dehydration does not itself cause diarrhea.

» Why does your head hurt when you are dehydrated?

One of the common symptoms of moderate dehydration is a headache. If you are experiencing a headache, consider whether dehydration could be the cause. If you are experiencing dehydration use a clinical rehydration formula (such as Hydralyte) which will restore the body’s fluid and electrolyte levels and relieve any dehydration present.

Rehydration

» How long after exercising should I rehydrate?

When you are planning to exercise, you should ensure that you start in a well hydrated state. To ensure you are well hydrated, aim to drink 8 glasses of water a day. Then, during exercise your fluid intake should match your fluid outlay. A good tip is to take 2 to 3 sips of an oral rehydration solution (such as Hydralyte) while performing sustained moderate to vigorous physical activity – this will help to prevent potential dehydration.

» What are some tips to rehydrate efficiently once you become dehydrated?

If you are experiencing dehydration, you need to act fast and drink an effective rehydration solution. The best option is a scientifically formulated oral rehydration solution (like Hydralyte) as this contains the correct balance of sugar and salt, to ensure that you rapidly restore what the body has lost. Oral rehydration solutions are formulated based on the World Health Organization guidelines for rapid and effective rehydration. It is important to start drinking these products as soon as you notice any signs of dehydration (such as dry mouth, dizziness, fatigue), and sip small amounts at regular intervals to enhance absorption (better than drinking a large bottle all at the one time. You should also monitor yourself for the signs and symptoms of more severe dehydration (such as fainting or very low blood pressure) – if these happen you should seek medical advice as soon as possible.

» What is the fastest way to rehydrate our body?

To rapidly rehydrate the body, you need to consume a hydration beverage that contains the correct balance of glucose and electrolytes for fast and effective absorption. The World Health Organization suggests an oral rehydration solution (such as Hydralyte), which provides fast and effective restoration of both fluid and electrolytes. In situations where you are fluid and electrolyte depleted (such as in cases of stomach flu, heavy sweating or other illnesses) an oral rehydration solution may provide fast and effective rehydration.

Hydration

» How do you know if you are hydrated?

One way to tell if you are well hydrated is to monitor your body for any signs and symptoms of dehydration, such as:

  • Increased thirst
  • Fatigue / Lethargy
  • Dizziness
  • Headaches
  • Dark or decreased urine output
  • Sticky or dry mouth
  • Loss of skin elasticity
  • Irritability

» Are hydration tablets the same as hydration drinks?

In the Hydralyte range, there are ready to drink solutions, powder packets and effervescent tablets. When these are consumed according to the directions for use on packaging, they are all equally effective to prevent and relieve dehydration.

» Is Hydralyte more effective than rehydrating with water?

Firstly, water is the best hydration fluid to consume on a daily basis, as part of a healthy, well-balanced diet. However, if you experience dehydration there are many rehydration drinks available. Oral rehydration solutions (such as Hydralyte) are clinically formulated to contain the correct balance of fluid and electrolytes. This allows for faster and more effective absorption of fluid and electrolytes by the body, and as a result, dehydration can be corrected very quickly.

» Does Hydralyte contain added sugars?
