Feel Dehydrated After Drinking lots of Water?
Why Are You Drinking So Much Water, And Still Dehydrated? Here’s the Truth
If only you had one of those days where you keep drinking water all day… but your mouth is dry and energy crashes happen, so basically, you feel dehydrated all the time and asks — why are you constantly dehydrated?
You’re not alone.
For many, drinking lots of water but still dehydrated, is confusing – even mildly irritating on the best days. We have all been told that the magic cure-all is water after all, right?
Well… not exactly.

Hydration isn’t just about between drinking water. So, let us proceed and discover what is truly occurring in your body.
if you’re one of those who has ever wondered, “Why am I constantly dehydrated even after drinking so much water?”— you’re not alone. And to be honest, the answer isn’t as easy as “drink more water.”
There are several reasons that you could be suffering from dehydration. Surprising
Reasons you’re dehydrated
Perhaps some of them — not this first one though!
- You’re not drinking enough water
You probably suppose that you are consuming sufficient water every single day. Yet it is easy to fall short without knowing. That is becausea majority of people (wrongfully) believe that all we need are eight glasses!
Here is what the everyday recommended value is in fact:
MAN: 100 ounces or (12.5 cups)(3.1 liters)
67 ounces/8.5 cups (2.0 liters) for men 73 ounces/9 cups (2.1 liters) for women
That’s a rough guideline. However, how much water you require depends on … erm, well actually you! Not just your sex, but how much you play, how often you are out — and at what temperature —how much you sweat, what foods you eat and so on…
Dr Rapp adds, “A good rule of thumb is to drink if you are thirsty.”
The thirst sensation, however, wanes with some people as they grow older. Children, they often do not complain about being thirsty.
If you rarely find yourself thirsty, drink at least half a liter of water a day, regardless of whether you have the thirst or not.
Can dehydration cause dizziness? The answer is yes…
- You have an electrolyte imbalance
Water is important. But it’s not enough.
As Dr. Rapp points out, water is hydrogen and oxygen. “But it does not include the electrolytes your body needs.
Electrolytes help control the fluid levels in your cells, and therefore are an essential component of proper hydration. They also assist with blood flow, nerve, muscle and brain function.
Will dehydration cause low blood pressure? – Yes
Many — but not all — electrolytes, such as sodium, potassium, calcium and magnesium chloride can be acquired through diet. Use sports drinks and rehydration solutions as a last resort instead.
- Maybe you are consuming excessive water at once
Chugging an entire gallon of water every morning is likely doing you more harm than good.
Your system purges the extra away by peeing when you overwhelm it with water. The problem with this is that it also carries away valuable electrolytes (along for the ride).
Instead, you should aim to hydrate more evenly throughout the day rather than trying to get it all out of the way at once.
- You’re sweating
When you sweat, fluids and electrolytes are lost. This can cause you to become dehydrated unless you replace what you have lost.
High in sodium & potassium, water is no substitute to replenish your electrolytes after losing copious amounts of sweat, Dr. Rapp reminds us! You also have to keep your electrolytes topped up. One of the many reasons orange slices are a favourite game-day snack for little leaguers & pro athletes alike!
- Are you drinking excessive coffee or does coffee dehydrate you?
Also, although it can be very tempting to count your morning cup of joe as a glass of water (because there is water in there), that’s not how hydration works. Some of the most popular drinks are diuretics. This means they have a diuretic effect; you discharge more and thus may dehydrate. Examples include:
Coffee
Sodas
Alcohol
- You’re sick
Battling a bug? Illnesses like the flu, food poisoning and other kinds of illnesses are common causes for dehydration. That is because, vomiting, sweating and diarrhea all causes dehydration.
If you are sick, ensure that you drink water and other clear liquids throughout the day. Your body can better handle it when spread throughout the day. According to Dr. Rapp, electrolyte or sports drinks are also recommended, tea and chicken broth.
I think chicken soup is what this is so brilliant about—it adds salt, it maintains water in your body—she said.

- You’re taking medication
Some medications cause dehydration. And that may be by design: diuretics, for instance, are formulated to flush out extra fluid from your system.
Fluid loss may also be an undesirable side effect of medications for:
Antacids
Laxatives
Blood pressure medications
If drinking dehydration is a possible side impact of an medication you take, always be sure to communicate with your health care/medicalhealthcare skilled.
Dr Rapp advises: “If you have heart failure or impacts of fluid retention, speak with your doctor about setting out an arrangement to get sufficient water regularly.
- You have a more serious health condition
A talk with your provider is indicated for dehydration. Sometimes it can be a symptom of more serious health problem.
You may immediately think of diabetes. But there are numerous medical conditions — including some that are acute as well as some that last a while — which create dehydration. Examples include:
Inflammatory bowel disease (IBD)
Sjögren’s syndrome
Cystic fibrosis
Gastroenteritis
Sepsis
Nausea (can dehydration cause nausea? ironically, yes—imbalance does)

Underlying Health Issues
It is not just bad habits that sometimes lead to dehydration.
It could be linked to:
Diabetes
Kidney issues
Digestive problems
Here is the answer:] For instance, dehydration can lead to a UTI? Yes—and recurring UTIs can also make hydration harder to maintain.
If you do have symptoms, and they continue for longer than a couple of days – see a doctor.
Addison’s disease
Dr. Rapp suggests treating dehydration like any other symptom would. And if anything changes (ie, your thirst level, your urine colour, or your fluid intake), tell your provider.
These are all symptoms of chronic dehydration—and they shouldn’t be ignored.
if you’re waking up dehydrated, it may mean your hydration habits during the day need improvement.
Some people even ask, “why does pure water dehydrate you?”
It doesn’t directly—but without minerals, it’s not fully effective.
does being dehydrated make you tired?
absolutely yes
