Causes of Diseases
Causes of Diseases: Most of the diseases will have many causes, rather than one single cause. These causes of diseases are classified into two types:
Poor health due to inadequate diet: It occurs due to deficiency of one or more nutrients, making the person unhealthy or susceptible to diseases, e.g. kwashiorkor, a nutritional deficiency disease occurring due to low protein diet. So, lack of good nourishment becomes second level of cause of disease.
Genetic disorders: These are present since birth; pass down from parents to offsprings, e.g. haemophilia.
Various pollutants present in environment : Pollutants in air, water and soil also contribute in causing diseases, e.g. intensive use of nitrate fertiliser causes methaemoglobinaemia.
Improper functioning of any body organ : Non-communicable diseases (i.e. non-spreadable diseases) like diabetes, blood pressure and heart diseases are due to the malfunctioning of body organs.
Lack of public services or poor economic conditions. It also contributes to the cause of disease. These causes become the third level cause of disease.
Note: The diseases, which are caused when organ and tissues degenerate and do not work well with increasing age are called degenerative diseases. Arthritis, disturbed sight and hearing defects are all degenerative diseases.
Infectious and Non-infectious Causes: Immediate causes of diseases belong to two distinct types.:
Lack of essential nutrients/substances in our diet, e.g. proteins, vitamins, minerals, etc.
Uncontrolled growth of tissues in any part of body.
Damage to any part by accident or by other means.

Students / Parents Reviews [10]
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
