What Does Dehydration do to Your Body?

Dehydration Facts – 15 Ways

Dehydration can make you sick in several ways. It is the loss of fluid from the body without having it replaced. The body cannot perform optimally when deprived of sufficient water need resulting in problems related to kidneys, heart, cholesterol, skin, muscles, and mood.

Kidney Problems

The body needs enough water to get rid of the toxins. Dehydration makes it difficult to flush out waste which shunts away blood from the kidneys. This does not allow proper nutrition to reach the kidneys which affects their function causing problems.

Muscle Cramps

Dehydration can be severe in terms of health performance ability. It can affect an individual’s aerobic fitness. Increased pressure on the heart can put stress on muscles. The result can be muscle soreness which may cause cramps.

Skin Damage

This is what you may think of dehydration comes to your mind. Although skin health is not the only effect of dehydration, it does cause damage. Slow blood flow to the skin can cut off the essential oxygen supply towards skin. This may stop nutrition to reach your skin affecting the outlook too.

Hydration is the most effective way of protecting your skin. Having more fluid based foods can help in coping up with the body’s fluid requirement.

High Pulse Rate

Low Blood pressure and high pulse rate is the common side effect of dehydration. The heart pumps out blood for the body which makes pulse rate. The pressure it exerts to push is the blood pressure.

When dehydration occurs, there is less fluid in the system causing less blood volume in the heart to be filled. This makes the heart work harder to push blood out to the body causing high pulse rate whereas the pressure is low.

Increased Appetite

It is always recommended to take water before your meal. The reason behind is that you do not feel thirst during the meal. This also makes sure that your body does not masquerade thirst as hunger as this will make you eat more.

Drinking water before a meal also makes you fuller and does not allow you to overeat. It rather avoids confusion for the body if fluid and food come separately. Sweat rate should also be taken into account as it may be different for changing weathers. It is important to fullfil what your body needs to avoid malfunction.

Bad Mood

The manifestation of fatigue has several reasons depending on the activities of an individual. Fatigue usually makes your mood low and it may become worse if the resulting factor is not worked upon.

Dehydration can affect the body’s energy levels and the ability to concentrate. This results making your feel tired. Women are more likely to suffer from dehydration.


Athletes commonly suffer from severe headaches because of dehydration. The condition can even become life threatening if overlooked. Headache occurs when the brain tissue loses water and makes a gap between the skull.

Also, less oxygen reaches to the brain when dehydration occurs because of low blood volume. It is therefore recommended to drink water when you feel pain.

Swollen Feet and Arms

The swelling of feet and arms is another effect of dehydration on your body. It is way of telling you are falling short of water supply. The kidney dysfunction affects the body’s ability to flush out toxins which may cause salt retention.

Excess fluid that is trapped within the body tissues is the reason why swelling occurs. Increasing your water intake can help you overcome swelling and many related problems.


Hydration is essential for the body parts to function properly. The parts slow down when tht do not get enough blood supply as a result of dehydration. Thirst is the indicator that you are dehydrated but it is still safe to have drink at this point.

Dehydration can make your urine dark in color. This means you should increase your water intake to stay well hydrated.

High Cholesterol

Lack of fluid in the body has an effect on cholesterol levels. The blood gets thicker ans it is then harder for the heart to push it through vessels. This also causes cholesterol to build up in the arteries to cause more damage.


Essential nutrients and water help in the digestion process. The stomach is inable to produce the acid if there is not enough water in the body. This may also result in acid reflux causing heartburn and other painful symptoms.


Water pushes the food down and encourages bowel movements. Dehydration does the opposite as it soaks up all fluid from food. This causes hard stools and makes you constipated.

Although it is important to increase your fluid intake, you may also follow some effective home remedies for constipation to cure the condition sooner.

Premature Aging

Dehydration weakens your body on the whole as all functions get affected. The largest organ of the body also struggles with premature aging as dehydration does not allow oxygen and nutrition to reach through it. There is less moisture retained in the skin which does not give a healthy look.

Bad Breath

Saliva has an important role for your overall health. It is anti bacterial in nature and can heal wounds. Lack of fluids in the body will also not allow for saliva production.

Bacteria can be produced in the body when dehydration occurs making your breath smell bad. This may also indicate that your body is dehydrated.

Airway Restriction

The body plays its role to preserve water when there is shortage. This is the self defense mechanism to have less effects of dehydration on the body. Although the body still loses fluid as sweat, it restricts the airways so as to save some percent of the loss.
