Are you Dehydrated? Common Diseases and Symptoms caused by Chronic Dehydration

  |   Health, Health Awareness, Healthy Life Style, Water   |   No comment

Water is a vital component of life, second only to oxygen.

The human body is made up mainly of water. Calculations show that it should contain 65% of water at a minimum. This goes up to 85% in the case of certain organs like the brain.

While everybody knows that man needs water to live, the exact reasons why it is so vital to health are rarely explained. This absence of information results in water being neglected as an important health factor.

Most people believe that dehydration is what happens when one runs out of water while walking through the desert. They also think that they take in enough liquids during the day. Indeed they drink coffee, tea, soft drinks or other beverages. However, most of these increases the water losses because they are diuretic and cause perspiration. Alcohol and tobacco consumption further increase losses.

During summertime and in hot countries where one is either exposed to high temperatures or lives in air-conditioned spaces, dehydration can occur very quickly and without one being aware of it.

According to studies, two out of three people are partially dehydrated. Even slight dehydration of no more than 2% of total body weight disturbs physiological functions and decreases the organism’s efficiency. Metabolism and energy levels are directly affected, and this extends even further to mood and mental alertness.

Fatigue and lack of energy

Dehydration is the most common reason for chronic fatigue. It is the primary reason why metabolism fails. Tissue dehydration causes a reduction in enzyme activity (enzymes increase the speed at which chemical reactions within the organism take place) and can slow down the energy production processes by a factor of up to 40% within one hour from the time it sets in.

On the psychological side, dehydration manifests itself by a severe lack of interest in daily activities.


Water distribution within the organism is prioritized. Where dehydration is chronic, the intestine absorbs as many liquids as possible, resulting in concentrated, hard faeces. This makes the excretion of faecal matter difficult and what is a natural process can turn into a serious annoyance.

Excess weight and Obesity

Dehydration is a key factor in obesity. Excess weight comes from eating more than the body can use or burn. But where does the tendency to eat more than necessary comes from? There are many answers to this question. A lesser-known one is thirst.

There are two ways to satisfy thirst:

  • one is to drink liquids
  • the other is to eat foods with a high water content

The second option provides the organism with the liquids it needs but unfortunately, it also contains unnecessary calories that contribute to weight gain. More often than we realize, we try to quench thirst by eating instead of drinking water.


Cholesterol is one of the most vital compounds used by the organism. However, its presence in the blood in high quantities can be an indicator (not the cause) of inflammation and increased cardiovascular risk in some cases.

A third of the cholesterol comes from food while the remaining two-thirds are produced by the organism itself. Hypercholesterolemia (the medical term for high cholesterol levels) can be traced to either external causes (food) or internal ones (overproduction).

One of the functions of cholesterol lies in the building of cell membranes. Dehydration is responsible for the draining of liquids from inside the cells. The organism responds by increasing cholesterol production to stop the loss. When this happens, increased cholesterol levels show that the cells are functioning under nonoptimum conditions, and it is thus possible to lower the amount of cholesterol in the blood through the intake of liquids with no other change in the diet whatsoever.


Dehydration can increase the repercussions of cancer through a variety of mechanisms:

– Dehydration increases oxidation (how fast damage to cells accumulates) and acidosis (increased acidity in the organism),

– lowers the amount of available oxygen,

– decreases the ability of the body to detoxify itself from chemical toxins and radiation,

– has an adverse effect on the function of the intestine and its flora,

– can cause damage to the DNA.

A mere five glasses of water a day decrease the incidence of colon cancer and bladder cancer by 45% and 50% respectively.

Premature Ageing

The aging process involves the gradual reduction of intracellular and extracellular liquids, i.e. liquids found inside and outside cells. A newborn baby’s body consists of 85% water. This percentage gradually decreases to about 70% in an adult and continues to decline as we get older.

This loss of water contributes to the reduction in tissue volume and is characteristic of the aging process. Dehydration intensifies and accelerates it. Chronic dehydration makes one grow old faster.

Additional symptoms

Other symptoms that may be caused by chronic dehydration:

  • Urinary tract infection: evidence shows that the urine of people who are dehydrated is more concentrated than the one of the those that are well hydrated. The increased amount of toxins the concentrated urine contains damage to the urinary system’s epithelium (inside lining), which increases thus the probability of microbial development.
  • Dental health: dehydration decreases the production of saliva and thus reduces the protection it offers to the teeth. People who exercise a lot and sweat profusely should be especially careful.
  • Cardiac disease: studies show that dehydration increases the risk of heart attack and stroke due to increased blood viscosity.
  • Dyspepsia: the secretion of peptic fluids in the stomach is lessened.
  • Low or high blood pressure: when dehydrated, blood volume isn’t enough to fill all of the body’s arteries and blood vessels. This renders the organism’s pressure regulating tasks problematic. The result is either high or low blood pressure.

Why are we dehydrated?

Chronic Dehydration affects anyone who either doesn’t take in enough liquids or can’t retain them.

Most of the water in the body is found inside the cells. But if the body is to keep the intracellular water certain conditions must be met.

  1. Sufficient amounts of minerals and salts must be present.
  2. The cell must be able to produce enough energy to run the pumps that regulate the amount of intracellular water.
  3. Adequate amounts of amino acids and proteins for the organism to build and maintain the mechanisms that control hydration.
  4. The organism must have at its disposal all of the micronutrients (vitamins, enzymes, fatty acids) necessary to the maintenance of the cells’ biochemical balance (homeostasis).

Drinking water while the above requirements aren’t met may worsen the dehydrated condition instead of improving it. Diuresis (the increase of urine production) causes the loss of vital minerals and micronutrients and makes water retention more difficult.

The intake of natural unrefined sea salt, containing over 80 minerals and other nutrients, helps substantially. Vegetable juices are an excellent source of high-value nutrients that can be absorbed immediately.

The intake of clean, good quality water in sufficient quantities, along with enough micronutrients to cover the organism’s needs, are the cornerstone of good health.

To Your Health!
