What is Obesity

Obesity is a chronic disease defined as the increase in size and amount of fat cells in the body. It can be mainly associated with a higher risk of gaining overweight, developing cardiovascular diseases, reduction in the quality of life, and an increase in mortality.

 

Obesity Definition

People who have severe cases of COVID-19 may require treatment in intensive care units or even mechanical assistance to breathe.
 

Diagnosis Of Obesity

The obesity diagnosis is based on the physical examination and medical history of the patient. If the calculation of the BMI is greater than 30 kg/m2, it’ll give the exact intensity factor in order to determine the severity of the obesity. The below stages can help in the diagnosis of obesity.

  • Physical examination
  • Clinical history
  • Blood analysis and imaging tests
