At the present days, we are feel and talk about the dehydration. This is just because of the high temperature.
A significant loss of body fluid that impairs normal bodily functions. Dehydration occurs when you use or lose more fluid than you take in, and your body doesn’t have enough water and other fluids to carry out its normal functions. If you don’t replace lost fluids, you will get dehydrated.
Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults.
Causes for Dehydration
The basic causes of dehydration are not taking in enough water, losing too much water, or a combination of both.
Sometimes, it is not possible to consume enough fluids because we are too busy, lack the facilities or strength to. drink, or are in an area without potable water (while hiking or camping, for example). Additional causes of dehydration includes :-
The most common cause of dehydration and related deaths. The large intestine absorbs water from food matter, and diarrhea prevents this from happening. The body excretes too much water, leading to dehydration.
Leads to a loss of fluids and makes it difficult to replace water by drinking it.
The body’s cooling mechanism releases a significant amount of water. Hot and humid weather and vigorous physical activity can further increase fluid loss from sweating. Similarly, a fever can cause an increase in sweating and may dehydrate the patient, especially if there is also diarrhea and vomiting.
High blood sugar levels cause increased urination and fluid loss. Tips for handling summer heat for people with diabetes.
Usually caused by uncontrolled diabetes, but also can be due to alcohol and medications such as diuretics, antihistamines, blood pressure medications and antipsychotics.
Blood vessels can become damaged, causing fluid to leak into the surrounding tissues.
Effects of Dehydration
It is a serious issue among many people with anywhere from two out of three people being unknowingly dehydrated. However there is surprisingly little awareness of the effects of. dehydration, especially when. considering its effects on the human body.
Our lifestyles are certainly part of. the. problem. Most people do not drink the recommended eight glasses (over 2 litres) of water every day to replace lost fluids. Drinking coffee or tea and spending time in air – conditioned or heated environments exacerbates the problem.
The average adult loses over 2.5 litres of water every day. We can lose approximately 0.5 litres from breathing, 0.5 litres when sweating in a temperate environment (this increases dramatically in hot. weather, heated rooms or when exercising) and anywhere from 1-1.5 litres through urination.
A drop of just 2% of our body water can cause the following. issues:
- Short-term memory loss
- Loss of concentration
- Dry skin
- Cognitive impairment
- Digestive problems (constipation)
If mild dehydration is not treated, the body begins to shut down. Shock, coma and death can occur if the replenishment of fluids does not take place.
Thirst, while being the indicator that dehydration is occurring, is unfortunately a poor early warning system. In fact, if you feel thirsty, you are already suffering from mild dehydration. Other common symptoms and signs of dehydration include:
- Dry mouth
- Decreased urination/dark coloured urine
- Sunken eyes
- Baggy eyes, wrinkled skin
- Low blood pressure
It is without a doubt a serious issue in today’s world. And the only way to counter, it is to ensure that at least 2 litres, or eight glasses, of water is consumed every day. Getting into the habit of drinking this amount of water will help counter the effects of dehydration and lead to a happy and healthy body and mind.
Symptoms of Dehydration
Severe. dehydration is a life – threatening medical condition caused by excessive fluid loss from the body. You can develop dehydration due to illness, prolonged exposure to heat or by. simply not drinking enough fluids. Contact your doctor immediately if you develop any of the symptoms of severe dehydration.
The most common symptom associated with severe dehydration is extreme thirst. When you body does not have an adequate supply of fluid to provide to your organs and tissues, it signals your brain to induce sensations of thirst. Increased thirst can also be accompanied by feelings of dryness or stickiness within your mouth.
People suffering from severe dehydration can begin to act abnormally as a symptom of this condition. If your body does not have enough fluid, you can begin to feel irritable or confused, explain health professionals at The Mayo Clinic. Children with this condition can appear unusually fussy or restless and may become severely fatigued or lethargic.
If your body is not adequately hydrated, it will conserve the fluid within your body by limiting urination. During episodes of severe dehydration, urine appears dark yellow or amber in color.
Poor Skin Elasticity
Your body needs fluid to keep your skin hydrated. Severe dehydration can cause your skin to appear dry, shriveled or flaky. You may also notice that your skin lacks its normal elasticity and does not rebound as usual when pinched.
Decreased Blood Pressure
Poor levels of fluid within the body can cause your blood pressure to decrease, explains the Merck Manual: Home Edition, a medical encyclopedia for patients and caregivers. Low blood pressure due to severe dehydration can cause symptoms that include headache, dizziness, increased heart rate or difficulty breathing. Such symptoms can worsen upon standing up or sitting up quickly and may cause you to feel unstable when you walk.
If you experience severe dehydration, you can develop a fever as a symptom of this condition. Fever symptoms are typically mild and can contribute to headache or dizziness in some patients. You may also notice that you do not produce any sweat, even when your body temperature is elevated due to fever.
Loss of Consciousness
Severe dehydration can cause some patients to faint or lose consciousness due to inadequate levels of body fluids. Loss of consciousness can be preceded by episodes of delirium or severe confusion. If these symptoms develop, seek immediate emergency medical care.
Signs of Dehydration
Don’t wait until your toddler is excessively thirsty. If they’re really thirsty, they may already be dehydrated. Instead, look out for these warning signs:
- dry, cracked lips
- dark-colored urine
- little or no urine for eight hours
- cold or dry skin
- sunken eyes or sunken soft spot on the head (for babies)
- excessive sleepiness
- low energy levels
- no tears when crying
- extreme fussiness
- fast breathing or heart rate
In the most serious cases, your toddler can become delirious or unconscious.
It can also be caused by heat exposure, high fever, vomiting and diarrhea, diuretic and laxative medications and fluid imbalance caused by certain conditions.
Follow these four steps to prevent dehydration:
- Drink plenty of water, as directed by your doctor.
- Eat foods with high amounts of water like fruits and vegetables.
- Avoid or limit drinks with caffeine like coffee, teas and soft drinks.
- Avoid or limit drinks with alcohol.
If you or your loved one has symptoms of severe dehydration, including excessive thirst, fever, rapid heartbeat, fast breathing, little or no urine, concentrated urine with a dark color and strong odor or confusion, contact your doctor immediately.
