What Is A Dehydration Headache?

Ever wondered why your migraine keeps getting more intense because of dehydration?

Perhaps you have not been drinking enough water, and you notice that each time you feel dehydrated, the feeling gets accompanied by a series of migraines and headaches.

Then what you’re feeling is a condition called dehydration headache.

About 60% of the average human body is made up of water, and without water and the right amount of electrolytes, body functions become impaired.

Regular activities like the excretion of liquid wastes such as sweat and urine include fluid loss in the body, and this lost fluid has to be replaced constantly.

Dehydration occurs when you do not take enough water into your body system, causing the body to lack the number of fluids needed to carry out its regular functions.

When this dehydration occurs, the brain also gets temporarily affected by fluid loss, and that’s what causes your dehydration headache.

Dehydration headaches might not feel the same for different people, as they can occur with a broad series of symptoms.

However, the most common sign in individuals with the condition is a pulsating ache on both sides of their head, which is often aggravated or elevated by their engagement in physical activities.

It can occur to each of us from time to time when the body experiences fluid loss, without fluid intake, to replace the loss.

In most cases, dehydration headache goes away when the individual takes in water, causing fluid and electrolyte balance to return to normal.

What Are The Symptoms Of A Dehydration Headache?

Our body relies on water to perform most of its daily functions, and a whole lot can be affected in the body when there is constant fluid loss without replacements.

Headache is usually known to be a symptom too the disease conditions, but in the case of a dehydration headache, it’s the primary symptom.

How Long Does Dehydration Headache Last?

Generally, dehydration headache is not expected to last for an extended period, as drinking enough water should make it go away.

As long as you take in enough water, your dehydration headache should go away within 3 hours.

Dehydration headaches that do not go away after this time frame are regarded as extreme and could be another complication entirely.

If your dehydration headache does not go away after you might have gotten well hydrated, then you should consult your physician.

In such a situation, there is a possibility that another condition aside from dehydration causes the headache.

That is, it is linked to other disease conditions other than dehydration.

Why Your Dehydration Headache Won’t Go Away?

Daily, the body requires a balance of fluid and electrolyte for several functions, including brain functions.

As the body loses water daily, electrolytes also get lost. Often, when this loss occurs, it can only get balanced by taking in enough water.

So when your dehydration headache cannot go away, that could only mean that you are not taking in enough water.

When you forget to get yourself hydrated enough, your dehydration headache might fail to go away.

Another reason your dehydration headache might not go away is associated with some other disease conditions.

Such a situation would warrant that you get yourself treated alongside getting hydrated. Some of these causes include:


Diarrhea is a disease condition characterized by the frequent passing of loose, watery stool and constant dehydration.

When you’re sick or down with diarrhea that causes severe dehydration and loss of electrolytes, your headache might not go away soon.

The best way to go about it is to treat your diarrhea to prevent the condition of abnormal fluid loss.


When you’re also sick and vomiting, you will experience fluid loss and dehydration.

Getting yourself hydrated might not be the only way to stop your headache; hence, the reason your dehydration headache isn’t going away.

Frequent Urination

Some certain medical conditions like diabetes, urinary tract infections, bladder stones e.t.c.

It can cause frequent urination in persons, which causes dehydration and loss of electrolytes.

Additionally, certain medications can also cause increased urination in persons.

Conditions like these might have to be treated and taken care of to reduce dehydration before your headache can go away.
