Causes & Symptoms Of Water Deficiency In Human Body

Did you know water can do all that for your body? Amazing!! More info water uses: Water (H2O) is one of the most important chemical substances required for the survival of all the living creatures on earth. It is a part of all the body tissues and body fluids including blood, urine, saliva, sweat, cerebrospinal fluid, gastric juices, pancreatic juices etc. 70% of the human body is comprised of water, 82% of blood is water; 70% of the brain and 90% of the lungs are nothing but water. In fact, it is believed that the origin of life on earth started from water. Water is necessary for almost all the body functions and activities. 

Functions : 

  • Blood in animals and sap in plants is composed mainly of water
  • Our bodies require about 1.5-2 litres of water daily, the requirement increases in summer
  • Helps in regulating body temperature
  • Moistens the body tissues (e.g. mouth, eyes, nose etc.)
  • Detoxification of waste products by flushing them out through the kidneys and liver
  • Important source of transport in the form of blood for various nutrients and oxygen
  • Dissolves various soluble nutrients and minerals to aid their absorption and digestion
  • Aids in preventing constipation  

Dietary Requirements: 

  • The daily intake/requirement of water is based on various factors like: weight, physical activity, illness, if any, and environmental conditions
  • In cases where intake of water is less than the daily requirement, the body starts conserving water and urine output decreases
  • Adult human body normally requires 2- 2.5 litres of water out of which 1 litre is directly gained from food and the remaining 1.5 litre has to be drunk 
Causes Of Water Deficiency In Human Body:
  • Excessive blood loss

  • Shock
  • Burns
  • Prolonged dry air exposure
  • Malnutrition
  • Certain diseases like cholera, yellow fever, etc.
  • Electrolytic imbalance

  • Excess intake of water beyond your requirement can increase the blood volume, and thereby, burden the cardiovascular system to pump and circulate this excess volume of blood

  • Electrolytic imbalance leads to seepage of water from the diluted blood into the cells, which can cause swelling and oedema of cells in any organ like brain, lungs, etc. 

Some Interesting Facts:

  • The body can store water but only in a limited quantity. For the optimal functioning of the body, water losses from urine, stool, sweat etc. needs to be replenished on daily basis
