09 September, 2020 Manisha Ailneni

Health is the main asset of human life. Taking care of physical and mental health is important before anything else. In modern, busy work schedules, extreme stress and anxiety are causing more damage to health. People are running after financial security and having a good career etc., and often forgetting about maintaining good health. We are often taking health for granted and as a result, we are affected by several health diseases.

What is Dehydration?

Dehydration means not having to consume water in the body. The human body requires a lot of water to keep the body healthy. When we do not replace the lost fluids this condition becomes severe. Mild dehydration may not harmful, but you may face problems with blood pressure, heart rate, and body temperature.

Severe dehydration occurs when the body uses more fluid than you intake on a regular basis. This will force your body to function without enough water. This condition requires medical attention. When left untreated, it will lead to high blood pressure, kidney stones or failure, brain damage sometimes even death.

If you are dealing with any kind of health condition and on regular medication, you can buy medicine online for safe and genuine medicine at affordable prices.

We lose body water daily through sweat, tears, breathing, urine, and stool. We can replace it by drinking water and eating foods that contain water. Loss of water leads to an imbalance in the electrolytes of the body. Electrolytes such as sodium, potassium, magnesium and calcium, other minerals, and salts are important in the proper functioning of the human body.

  • There can be many other reasons for losing water like sweating, fever, vomiting, diarrhea, or exercising in hot weather, etc.
  • Some medication which causes excessive urination is also a reason for dehydration.
  • If you experience stress regularly, it will weaken the adrenal glands and results in dehydration.
  • Smoking tobacco will dehydrate your skin and lips.
  • Overconsumption of alcohol can remove water from the blood very quickly and makes you dehydrated.

Severe Dehydration symptoms: 

Symptoms of dehydration may be different in each person. Some of the chronic dehydration symptoms are,

  • Thirst
  • Dry mouth
  • Dry skin and lips
  • Dizziness
  • Tiredness
  • Lightheadedness
  • Headache
  • Muscle cramps
  • Fatigue

  • Less urine or urine that is in yellow or light brown color
  • Confusion and fainting

Complications of Severe Dehydration:

Heat injury: When you are doing excessive workouts, the body loses more fluids. If you don’t drink enough fluids, you may end up having heat injuries, cramps, and heat exhaustion. If it becomes severe, you may experience life-threatening heatstroke.

Kidney failure: Kidney requires a sufficient amount of fluids, as they filter and remove impurities from the body. Due to the lack of fluids, kidneys will no longer be able to remove excess fluids and waste materials. This condition will allow bacteria to accumulate and results in kidney stones, urinary tract problems, etc.

Seizures: Electrolytes such as potassium and calcium helps in carrying the electrical signals from cell to cell. Dehydration causes an imbalance in electrolytes and the electrical messages in the body will be mixed up. This condition leads to involuntary muscle contractions and loss of consciousness.

Low blood volume shock: This is a life-threatening and serious condition of dehydration. Low blood volume causes low blood pressure and drops the amount of oxygen in the body. As oxygen plays a vital role, a drop in its levels causes damage to the body. As the number of blood decreases, it causes strain in the heart.

Swelling of the brain: After a severe dehydration condition, when you drink water, the body tries to pull water back into the cells. This causes swells to rupture and damage. Often brain cells are affected, which can lead to coma and death.
