What Happens When You Don't Drink Enough Water? 10 Hidden Effects on Your Body

  1. What happens to your blood when you become dehydrated? Blood contains: Red blood cells. White blood cells. Platelets. Plasma, which is mostly water. Proteins, electrolytes, nutrients and other substances. When the body loses too much water, plasma volume can decrease. This can cause hemoconcentration, meaning some substances in the blood appear more concentrated. Possible effects include: Increased blood viscosity under some circumstances. Reduced circulating blood volume. Increased strain on the cardiovascular system. Reduced blood flow to organs in severe dehydration. This is different from having excessive cholesterol or fatty deposits in arteries. NCBI+2 2. Does dehydration increase cholesterol readings? This is where our article can become particularly interesting. A small human study involving 15 healthy participants found that fasting without fluid replacement produced higher measured total cholesterol, LDL cholesterol and HDL cholesterol than fasting with water and sal...

Could What You Eat Be Affecting Your Long-Term Health?

 

We often think we are making our own food choices.

But are we?

Walk into a supermarket, convenience store or fast-food restaurant and you will find attractive packaging, familiar brands, sweetened drinks, snacks and ready-to-eat meals everywhere.

The problem isn't that we occasionally eat these foods.

The problem is that we can consume them regularly without really knowing what we are putting into our bodies.

And one of the simplest things we often overlook is the food label.

The Mistake We Make Without Realising It

Most of us don't consciously decide:

“Today I'm going to eat more sodium, saturated fat or sugar.”

Instead, we choose what is convenient, familiar and appealing.

Highly processed foods can contain significant amounts of sodium, free sugars and unhealthy fats. WHO recommends limiting these nutrients as part of a healthy diet.

So perhaps we should develop a simple habit:

Turn the package around and read the label.

Look at the sodium, saturated fat, sugars, serving size and ingredient list.

A famous brand doesn't automatically mean a healthy choice.

When Food Becomes a Culture

Fast food and branded drinks have become part of modern social life, particularly among younger generations.

Meeting friends may mean fast food.

Taking a break may mean a sweetened coffee.

Watching a movie may mean snacks and a soft drink.

None of these things is necessarily a problem by itself.

The question is what happens when an occasional treat becomes an everyday habit.

The Malaysian Adolescent Health Survey 2022 found that about 30.5% of adolescents reported drinking carbonated soft drinks at least once a day during the previous 30 days.

That doesn't mean every young person has an unhealthy diet. But it shows how sweetened drinks can become part of daily habits.

What About Plain Water?

This is something I learned personally.

When I was younger—even before I married at 35—I hardly drank one litre of plain water a day.

Most of my drinks came from coffee.

And I could drink up to eight cups of coffee a day.

Looking back, I realise how little attention I paid to plain water.

I simply didn't think about it.

Interestingly, Malaysian data don't support the idea that everyone drinks too little water. The National Health and Morbidity Survey 2019 found that around three-quarters of Malaysian adults drank enough plain water according to the survey's definition.

But among adolescents, the 2022 survey found that 42.4% drank fewer than six glasses of plain water a day.

So perhaps the bigger lesson isn't about hitting one magic number of litres.

It is about being conscious of what we drink every day.

Then Came the Blood Test

When I was around 38, I went for a blood test.

The results showed that my triglycerides were quite high, and my cholesterol was also high.

At the time, I didn't fully appreciate what those numbers meant.

I was relatively young, and I didn't necessarily feel that anything was wrong.

That experience taught me something important:

Our bodies can sometimes tell us something long before we feel it.

High cholesterol often has no obvious symptoms, which is why a blood test can reveal something we would otherwise never know.

My Family History Added Another Lesson

Several years later, my mother was diagnosed with diabetes.

She came from a rural environment where people in her generation simply didn't go for regular blood tests.

If you didn't feel sick, you generally didn't think you needed a test.

Today we know that having a close family member with type 2 diabetes is one of the factors associated with increased risk.

That doesn't mean that family history determines our future.

But it does give us another reason to pay attention to our health, our lifestyle and appropriate health screening.

We Don't Have to Change Everything Overnight

Healthy eating doesn't mean we can never enjoy fast food, coffee, desserts or our favourite drinks.

It means becoming more aware of our patterns.

Maybe start with something simple:

  • Read the nutrition label before buying packaged food.

  • Pay attention to sodium, sugar and saturated fat.

  • Choose plain water more often.

  • Don't let sweetened drinks become an automatic daily habit.

  • Eat highly processed foods less frequently.

  • Pay attention to portion sizes.

  • Take routine health checks seriously, especially when family history gives you additional risk factors.

Small changes are usually easier to maintain than trying to change everything at once.

The Lesson I Learned

When I look back at my younger years, I can see how little attention I paid to my daily habits.

Eight cups of coffee could disappear in a day while plain water hardly entered my routine.

I didn't consciously choose to have a diet high in anything.

I simply wasn't looking closely enough.

Then a blood test showed me that my triglycerides and cholesterol were already high.

Years later, my mother's diabetes gave me another reason to think about family history and long-term health.

These experiences changed the way I look at food.

Final Thought

Healthy eating isn't about being afraid of food.

It is about awareness.

Before we eat something, perhaps we should occasionally ask:

What am I actually putting into my body?

Before we make a drink, ask:

Do I really need this, or has it simply become a habit?

And when we have the opportunity to check our health, don't wait until we feel something is wrong.

Because our health is rarely shaped by one meal.

It is shaped by the habits we repeat—often without even thinking about them.
