Nature of Diseases

Nature of Diseases: Infectious, Deficiency, Functional and Degenerative

Diseases are an integral part of human life. But what is a disease? By definition, it is a deviation from a normal state of health that results in disruption of normal body function. Diseases can have different natures and causes of their occurrence. Let's look at four types of diseases that can be distinguished by their nature.

Infectious diseases

Infectious diseases are caused by a pathogenic agent such as a virus or bacteria. Examples of such diseases are typhoid, hepatitis, influenza and diphtheria. Infectious, or infectious diseases, are caused by our immune systems, which fight the pathogen. They can be transmitted through direct and indirect contact, air, water, food, contaminated objects or insects. The presence of a source of infection and transmission routes are two main conditions for the emergence of infectious diseases.

Diseases associated with deficiency of any substances

Another type of disease is disease associated with a deficiency of any substance. They are caused by a deficiency or absence of any substances necessary for the body, such as vitamins. Examples of such diseases are beriberi, scurvy, and rickets.

Functional diseases

Functional diseases are caused by poor functioning of an organ or regulatory gland. This can be caused by various reasons such as genetic abnormalities, poor lifestyle or stress. Examples of such diseases are diabetes and acromegaly.

Diseases associated with degeneration

The fourth type of disease is diseases associated with degeneration. They are caused by aging or destruction of an organ. Examples of such diseases are liver cirrhosis and cancer.

Flu is one of the most common infectious diseases. Its name comes from the German word "gruppen", which means "to cower" or "to shiver from the cold." Although influenza is easily treatable, it is still dangerous and influenza epidemics still occur.

In conclusion, understanding the nature of diseases can help us improve our health and prevent the development of many diseases. Please remember that it is important to take precautions to avoid infection and take care of your health, including eating a healthy diet, regular physical activity, getting enough rest and maintaining good hygiene. In addition, it is necessary to take seriously the treatment and prevention of diseases, including contagious diseases, in order to maintain one’s health and well-being.
