Dehydration symptoms in Adults

What is Dehydration?

Dehydration happens when your body uses or loses more fluid than it takes in, and your body cannot carry out its usual tasks due to a lack of water and other liquids. You will get dehydrated if you do not restore lost fluids.

Dehydration Symptoms

The dehydration symptoms may arise before complete dehydration has occurred. Thirst-coloured urine and reduced urine output are the initial signs of dehydration. Urine colour is one of the most significant predictors of hydration status, with clear pee indicating adequate hydration and darker urine indicating dehydration.

The following signs of dehydration appear when the illness worsens to mild dehydration:

  • Headache
  • Muscular Weakness
  • Dizziness
  • The Mouth Seems To Be Dry
  • Lack Of Energy


Severe dehydration (loss of 10-15% of body water) is marked by extreme versions of the symptoms listed above, as well as:

  • Sunken Eyes
  • Drowsiness
  • A Faster Heartbeat
  • Fever
  • Blood Pressure Is Getting Too Low
  • Lack Of Sweat


Symptoms in children

  • Sunken Cheeks And/Or Eyes
  • No Tears When Crying
  • Irritable
  • In Babies – A Sunken Fontanel
  • No Wet Diaper For 3 Or More Hours
  • Dry Tongue And Mouth


Causes of Dehydration

Dehydration may happen for various reasons, including not drinking enough because you’re unwell or busy or not having access to safe drinking water when traveling, trekking, or camping. Other causes of dehydration include:

  • Vomiting causes a loss of fluids and renders drinking water tough to balance.
  • Diarrhea is the most prevalent cause of dehydration and mortality due to dehydration. The large intestine absorbs water from meal particles, but diarrhea hinders absorption. Dehydration occurs when the body excretes too much water.
  • Diabetes causes excessive urine and fluid loss due to elevated blood sugar levels. For people with diabetes, here are some tips on how to deal with the summer heat.
  • Burns can cause blood vessels to rupture, allowing fluid to flow into the surrounding tissues.
  • Sweating is the body’s natural cooling process, and it releases a lot of water. Sweating can be exacerbated by hot and humid conditions and intensive physical exertion. Similarly, a fever can produce excessive perspiration and dehydration, especially when simultaneously experiencing diarrhea and vomiting.
  • Frequent urination is most commonly caused by uncontrolled diabetes, although it can also be caused by alcohol or drugs. 


Risk factors

  • Dehydration related complications
  • Heat-related injuries can range from minor cramping to heat exhaustion or heat stroke.
  • Low blood volume causes a drop in blood pressure and a reduction in the quantity of oxygen reaching tissues, which can be fatal.
  • If dehydration is not treated, it can lead to significant consequences, such as:
  • Kidney disorders, such as renal stones, urinary tract infections, and kidney failure, are possible.
  • An electrolyte imbalance causes seizures.



  • Dehydration will be diagnosed by a doctor using both physical and psychological examinations. Dehydration is commonly diagnosed when a patient exhibits symptoms such as disorientation, low blood pressure, fast heartbeat, fever, lack of perspiration, and inelastic skin.
  • Blood tests are commonly used to examine salt, potassium, and other electrolyte levels as well as kidney function. A urine analysis will provide you with a lot of information to assist you in figuring out if you’re dehydrated or not. The urine of a dehydrated individual will be darker in color and much more concentrated, having a specific degree of ketones.
  • Doctors look for a depressed soft area on the infant’s head to detect dehydration. They could also search for things like a lack of perspiration and specific muscle tone features.



  • Dehydration must always be addressed by restoring the body’s fluid balance. Clear liquids, which include water, clear broths, frozen water or ice pops, or sports drinks, can help with this (such as Gatorade).
  • Meanwhile, some dehydrated individuals will require intravenous fluids to rehydrate. Caffeine-containing beverages, such as espresso, tea, and sodas, must be avoided by dehydrated people.
  • Dehydration can be caused by underlying diseases that should be addressed with the proper medicine.



  • Drink plenty of water and consume meals high in water, such as fruits and vegetables, to avoid dehydration. For most healthy people, letting thirst be your guide is an acceptable daily guideline. Essential therapy for dehydration is prevention.
  • Most people should be able to avoid dehydration by drinking enough water and eating high-water-content meals (such as fruits and vegetables).
  • People should avoid exercising in high heat or during the warmest portion of the day, and anyone exercising should make rehydration fluids a priority. Because the symptoms of dehydration in adults are the people who are most likely to get dehydrated, additional care should be paid to ensure that they get adequate fluids.
