Types of Disease

Types of Disease: A disease is a specific aberrant condition that adversely affects an organism’s overall structure or function and is not immediately brought on by any external injury.

It is common knowledge that diseases are medical illnesses characterized by distinct indications and symptoms. Pathogens or internal dysfunctions may be the external causes of disease.

Internal immune system abnormalities, for instance, can result in various illnesses, such as different types of immunodeficiency, hypersensitivity, allergies, and autoimmune disorders.

Diseases Classification

  • Diseases can be categorized according to their pathogenesis, the method they are caused, or their symptoms (s).
  • Alternately, diseases can be categorized according to the organ system that is affected, albeit this is frequently more difficult because many diseases affect many organ systems.
  • The inability to accurately describe and categorize diseases, mainly when the source or pathophysiology is unknown, is a significant challenge in nosology.
  • As a result, diagnostic labels frequently represent one or more symptoms (syndrome).
  • The observational relationship between clinical symptoms and pathological examination is the basis for the traditional classification of human diseases. If the reason is known, it is preferable to group them by it.
  • The ICD, developed by the World Health Organization, is the most popular and widely used classification of diseases. It is updated regularly. The ICD-11 is currently the most recent publication.

Different Types of disease

The emotions or changes that an organism goes through when it is ill are known as symptoms. These can be brought on by a virus, the environment, one’s way of life, or a combination.

Diseases can be grouped into two types:

Measles, food poisoning, and malaria are infectious diseases that affect people and can spread from one being to another or from one organism to another.

Non-communicable conditions, which cannot be spread from one person or animal to another

Non-communicable diseases include:

  • cancer
  • diabetes
  • genetic disorders and diseases
  • cardiovascular disease is another name for heart disease.
  • neurological conditions

Additional elements that may significantly impact both physical and mental health include:

  • diet
  • Lifestyle elements like drinking and drug usage are
  • situations that could cause stress in a person’s life

Different Diseases

  • There are two categories of diseases.
  • infectious conditions
  • non-contagious illnesses

Infectious Diseases

  • Infectious diseases are conditions that transfer from one person to another. They are typically brought on by pathogens, which are microbes (fungi, rickettsia, bacteria, viruses, protozoans, and worms).
  • Pathogens may leave the host when an infected person releases body fluids and infect a new person (sneezing, coughing, etc.). Examples include malaria, chicken pox, and cholera.

Non-infectious Diseases

  • Pathogens bring on these illnesses, but age, dietary deficiencies, gender, and lifestyle choices can also have an impact.
  • Examples include cancer, diabetes, and hypertension.
  • They contain the individual who has contracted them and does not spread to others. Other non-infectious disorders include heart disease, cataracts, Alzheimer’s, asthma, and asthma.
    Degenerative Diseases
  • The body’s essential organs malfunction primarily brings them on due to the aging process of cells.
  • Increased bone brittleness is a sign of degenerative illness in conditions like osteoporosis. Bone fractures are more likely as a result.
  • Neurodegenerative disorders are characterized by the degeneration of central nervous system cells, such as neurons.
  • A notable example of this disorder is Alzheimer’s. Aging and bodily wear are the two leading causes of degenerative disorders. Lifestyle decisions cause others, and some are inherited.
