How can you tell if you are dehydrated?
Thirst can be the first sign of dehydration; but it’s not a reliable symptom. For instance, adults can become dehydrated without feeling thirsty.
This is why you should drink sufficient amount of water throughout the day. Other indications of fluid loss include a decrease in urine production and unusually dark urine.
It’s especially important to look for symptoms during an emergency where drinking water isn’t readily available – like during an earthquake, hurricane, or tornado.

A change in urine color is one of the best dehydration signs. Clear urine indicates that you’re well hydrated.
But, dehydration signs and symptoms vary depending on age as seen below.

Signs of severe dehydration
How does dehydration affect the body? Severe dehydration can be defined as the loss of approximately 15% of the body’s water. The symptoms of dehydration include:
- Sunken eyes
- Lack of sweating
- Dark shriveled skin
- An increase in the heart rate or rapid heartbeat
- Low blood pressure
At what point should you call your doctor?
Contact your general practitioner or call 911 in a medical emergency if you or your loved one experiences the following symptoms dehydration:
- Diarrhea for 24 or more hours
- Is unable to keep any fluids down
- Is irritable, overly sleepy, disoriented, and unusually inactive
- Has black or blood-stained stool
What are the stages of dehydration?
Doctors classify dehydration in three stages. These are:
- Moderate and
Balancing or reversing mild or moderate dehydration can be done by drinking fluids containing electrolytes, also known as salts. Prolonged dehydration adversely affects your health and can cause death.
Skin turgor definition
Skin turgor is the elasticity of skin. For instance, when you pinch the skin on your arm, it should return in place within one or two seconds. Decreased skin turgor means that your skin takes longer to return to its normal position. The skin turgor test is often used to determine the level of dehydration. Poor skin turgor can occur in severe or moderate fluid loss.
What causes dehydration?
The primary cause of dehydration is the failure to take sufficient water or other beverages and losing excess amounts of fluids. Various factors in today’s fast-paced world make it challenging to keep up with the 8 -glass rule. These include:
- Being in an area that lacks clean drinking water
- Being too occupied to drink much water
- Lacking the strength or even the facilities to take much water
- Being in hot weather
It can also be caused by:
Diarrhea is an example of one of the most common causes of dehydration and, in severe cases, death. Usually, the large intestine absorbs water from food and diarrhea can inhibit this process. When you suffer from diarrhea your body causes you to lose water in excess amounts which causes increased dehydration.
Vomiting excessively leads to loss of fluids in the body and to continue replacing them can be a tough.
High levels of blood sugar trigger frequent urination which leads to excess loss of body fluids. Recurrent urination can also be caused by alcohol and medications such as antihistamines, diuretics, antipsychotics, and blood pressure medicine.
Sweating is the body’s cooling technique where it discharges some amount of water. Engaging in intense physical activity can trigger excessive sweating which increases the amount of fluids your body loses. Suffering from fever can also increase sweat which can make you become dehydrated. This can be worse if you are vomiting and experiencing diarrhea at the same time.
Burns can cause damage to the blood vessels resulting in fluid leaks in the surrounding tissues.
Who’s more at risk of dehydration?
It can happen to anybody, but it’s important to note that some people are at a higher risk. They include:
- People living in areas with high altitudes
- People with chronic illnesses such as kidney disease, cystic fibrosis, adrenal gland disorders, and diabetes
- Athletes who participate in endurance events such as cycling, triathlon, and marathon tournaments
- Infants and children due to vomiting and diarrhea
- Dehydration in older adults and the elderly is common and can be caused by failure to drink enough water in a bid to avoid frequent visits to the toilet at home.
Uncontrolled dehydration can cause severe complications such as:
- Low blood volume
Insufficient blood in the body lowers blood pressure and reduces the amount of oxygen penetrating through tissues. This can be risky and should be controlled immediately to prevent a medical emergency.
Seizures can occur due to electrolyte imbalance.
- Heat injury
Prolonged exposure to extremely high temperatures can trigger various types of heat injury such as heat stroke, heat exhaustion, and mild cramps.
How to diagnose dehydration
To establish whether or not a patient is dehydrated, the doctor may need to perform a mental and physical examination. If they present the symptoms indicated above, the doctor may treat them for dehydration. Often, blood tests are conducted to check for kidney function, potassium, sodium, and levels of other electrolytes.
Electrolytes are chemicals that control hydration in the human body. They are critical for muscle and nerve function. Doctors usually rely on urinalysis to determine dehydration. As we have seen above, dehydrated people will have overly concentrated and darker urine and high levels of ketones.
Diagnosing dehydration in infants is done through checking for a sunken soft spot on the skull. Doctors can also check for specific muscle tone.
What is the fastest way to cure dehydration? It can be treated by drinking water or any beverage that’s within room temperature.
What is the best thing to drink when you are dehydrated? Drink lots of clear fluids such as broths, water, sports drinks, and ice pops. Keep away from caffeinated beverages such as coffee, soda, or tea because they increase bladder activity which can dehydrate you.
Any underlying conditions that could be triggering dehydration, like with older adults, should also be treated using the correct medication depending on the doctor’s advice, diagnosis, or treatment. Some of these medications are available online and over the counter. They include anti-fever medications, anti-emetics that help control vomiting or diarrhea.
What should you do in the case of heat exposure?
Here are some tips to help you or your loved one cool down from heat exposure.
- Loosen or remove excess clothing
- Move to an air-conditioned area to regulate body temperature
- In case air conditioning is unavailable, place the affected person outside under the shade or near a fan. You can also wrap a wet towel around the patient’s forehead.
- Don’t expose the patient to extremely cold conditions such as ice water or ice packs. This can cause constriction and a decrease in blood vessels to worsen the symptoms of dehydration
- Spray lukewarm water on the patient using a spray bottle
How to prevent diarrhea
Prevention is key when it comes to treating dehydration and eating foods and fruits with high water content and drinking lots of fluids will help prevent dehydration. You should also avoid engaging in strenuous activities during the hottest part of the day.
If you work out regularly or are an athlete, you should replenish fluids regularly. Remember, young children and older adults / elderly are at a higher risk of suffering from dehydration. You want to monitor them and ensure they get enough fluids.
How to take care of dehydrated patients
If you or your loved one is recovering from this, make sure they:
- Take prescription medication as directed by the doctor
- Attend hospital appointments as directed
- Take lots of fluids to remain well hydrated and replenish lost fluids
- Be on the lookout for signs of dehydration
How do dehydrated patients recover?
Once it is treated and any underlying causes determined, many people recover normally. Managing mild to moderate dehydration resulting from extreme exercise, heat exposure, or low water intake is easy. Still, the recovery process can slow down in severe cases, or when any underlying causes aren’t well managed.

How long can symptoms of dehydration last?
Often, you can reverse the signs of mild and moderate dehydration by increasing your fluid intake. In case of severe dehydration, however, seek immediate medical attention.
Can severe dehydration cause kidney failure?
Water helps flush out waste from your system in the form of urine. It also facilitates open blood vessels to enable nutrient-dense blood to penetrate to your kidneys with ease. So, you need to drink water. When dehydration occurs, the execution of this process becomes difficult. Mild dehydration not only inhibits normal body operations, but it can also cause excess fatigue. Severe dehydration can lead to kidney failure.
This is why you should be drinking fluids after strenuous exercises or if you live in overly humid or warm weather areas. Some studies suggest that prolonged exposure to dehydration may cause permanent kidney damage.
Dehydration causes the accumulation of acids and waste in the body. As a result, your kidneys get blocked by muscle proteins, also known as myoglobin. It’s worth mentioning that dehydration can cause urinary tract infections and trigger the formation of kidney stones.
If action is not taken to control the condition early enough, it can eventually cause kidney damage. When you’re well-hydrated, you’re unlikely to suffer kidney stones.
Can severe dehydration cause seizures?
Yes. Electrolytes such as sodium and potassium enhance transportation of electrical signals between cells. When electrolytes are imbalanced as a result of dehydration, normal electrical messages are likely to get mixed up. This can cause unintended muscle contractions and unconsciousness in severe cases.
Can severe dehydration cause stroke?
People who are well hydrated before suffering stroke have a high chance of recovering as opposed to dehydrated people. Research conducted on 168 ischemic stroke patients found that:
- Approximately half of them were dehydrated by the time of their admission to the hospital.
- The condition of the dehydrated patients was highly likely to get worse compared to the hydrated patients
- The stroke condition was constant in approximately 42% of the dehydrated patients compared to 17% of hydrated patients.
