Dehydration: Signs, Symptoms, and How to Stay Hydrated

Ever had that annoying headache, sudden wave of tiredness, or felt like you could drink a whole ocean? Yep, you might be dehydrated basically, your body is losing more fluids than it's getting. Dehydration is super common, but knowing the deets is key to staying healthy. (1) This blog post will break down what dehydration is, how serious it can get, the first symptoms you might notice, why it happens, and what can make you more likely to get mild to moderately dehydrated. Plus, we'll cover the possible complications and, most importantly, how to tackle and prevent it. Oh, and we'll chat about how products like Liquid I.V. can help keep you hydrated.

What is Dehydration?

Dehydration happens when your body loses more water than it takes in. This imbalance messes with all the important stuff your body does. Maintaining fluid balance is important for normal functioning of our body. Water is our life - it helps distribute nutrients to cells and gets rid of waste. Plus, it keeps your body temperature in check. (2)

When you lose more water than you take in, your total body water volume drops. This can also throw off the balance of electrolytes like sodium and potassium, which are super important for your nerves and muscles. (2)

Levels of Dehydration

Dehydration isn't just a one-time thing; it can range from mild to severe based on how much body weight you've lost due to not having enough fluids. Generally, dehydration is split into three levels: mild, moderate, and severe. (3)

Mild dehydration, characterized by a fluid loss making you experience a slightly dry mouth, increased thirst, and reduced peeing. 

As dehydration progresses to the moderate level, the signs become more noticeable. Your mouth will feel drier, there may be an increased heart rate, further reduced peeing, tiredness and headaches. 

Severe dehydration, representing a very high fluid loss and, is a serious condition requiring immediate medical attention.

Symptoms of Dehydration

The symptoms of dehydration can vary depending on age and extent of fluid loss. Recognizing these signs is the first step to tackling dehydration. In adults, early signs of mild to moderate dehydration can include feeling super thirsty, peeing less often, and having darker pee. Other common symptoms are feeling tired, dizzy, and having a dry mouth. Some people might also get headaches or muscle soreness. If you feel really bad, see a doctor. (4)

Causes of Dehydration

Dehydration can happen for a bunch of reasons; it is basically an imbalance between fluid in and fluid out. Sometimes, it's as simple as not drinking enough water, because you're busy, traveling, or it's hot and humid.

Excessive fluid loss is another biggie. Sweating, a natural cooling process, leads to significant water loss, especially in hot weather, during workouts. Some medical conditions like diarrhoea, and vomiting can also disturb this balance. (3)

What are the Risk Factors for Dehydration?

Our climate affects us the most. Hot or humid weather makes you sweat more, and high altitudes can cause faster fluid loss through breathing. Active folks like athletes and those spending a lot of time outdoors are at higher risk because they sweat more. (5)

Complications of Dehydration

When your body doesn't get enough water, it can cause a lot of problems. For example, if your mouth gets dry, it can make your breath smell bad. Not having enough water can also make you feel really tired and give you headaches. Your stomach might hurt because your muscles cramp up and your intestines try to take water from the food you eat. It's important to drink enough water to keep your body working well and avoid these issues. (6)

How to Treat Dehydration

The main goal in treating dehydration is to get the fluid balance back. Drinking water is a good start! Sip fluids slowly and frequently. Adding electrolyte rich drinks can help in balancing the fluids more effectively, especially when you've been sweating a lot. Drinking skim milk, coconut water or fruit juices can add some natural sugars and electrolytes along with water. Severe dehydration needs immediate medical help. (1,3)
