disease definition

what is a disease definition?

From the first glance, we find the answer to the question "What is a disease?" Very direct and clear.

We feel like we have an intuitive grasp of the idea, as we bring our minds to old and other images or memories of colds, cancer, or tuberculosis.

But one look through any medical dictionary shows that crafting a definition of disease is surprisingly difficult.

It is not useful to define disease as the opposite of health, given that definitions of health are in turn equally complex and perhaps even more.

Hence, the World Health Organization defines health as a state of complete physical, mental and social well-being that affects a person, and not merely the absence of disease or infirmity.

disease definition

Disease definition, any harmful deviation from the normal structural or functional state of the organism, is generally associated with certain signs and symptoms and is different in nature from a physical injury.

The affected organism usually shows signs or symptoms of its abnormal condition.

Thus, the normal state of the organism must be understood in order to recognize the characteristic features of the disease.

However, the sharp difference between illness and health is not always clear.

The study of disease is called pathology. It involves determining the cause (etiology) of the disease, understanding the mechanisms of its development (pathogenesis), structural changes associated with the disease process (morphological changes), and the functional consequences of these changes.

It is necessary to correctly determine the cause of the disease in order to determine the correct course of treatment.

Both humans, animals, and plants are susceptible to diseases of some kind.

However, what disrupts the normal functioning of one species of the organism may not have an effect on other species.

disease meaning

A disease is a dysfunctional or improperly functioning organ, part, structure, or system of the body resulting from the influence of genetic or developmental errors, infection, toxins, nutritional deficiency, imbalance, toxicity, or unfavorable environmental factors.

disease meaning is any abnormal condition in a plant that interferes with its vital physiological processes, caused by pathogenic microorganisms, parasites, or unfavorable environmental, genetic or nutritional factors ...

That is, it is a harmful, corrupt, or pathological state of mind or society.

Information about disease meaning

Death from sickness is referred to as death from natural causes. Infectious illnesses, deficient diseases, hereditary diseases (covering both genetic and non-genetic hereditary disorders), and physiological diseases are the four basic categories of disease.

Diseases can also be classed in several ways, such as communicable vs non-communicable.

Coronary artery disease (blood flow blockage) is the most lethal illness in humans, followed by cerebrovascular disease and lower respiratory infections.

Neuropsychiatric illnesses, such as depression and anxiety, are the leading causes of illness in developed nations.

Disease definition summary

Here we summarize the most important things to know about the definition of diseases:

• A disease is an abnormal state that has a negative impact on the structure or function of all or part of an organism and is not caused by immediate external harm. Diseases are commonly described as medical illnesses with unique indications and symptoms.
• Infectious illnesses are clinically obvious disorders caused by the presence of harmful microbiological agents such as viruses, bacteria, fungus, protozoa, multicellular organisms, and prions, which are abnormal proteins.
• An acquired disease is one that developed at some point throughout one's life, as opposed to a congenital condition, which was there at birth.
• A primary disease is one produced by an underlying cause of sickness, as opposed to a secondary disease, which is a sequela or complication induced by the original disease.
• A bacterial infection can be primary, in which a healthy individual is exposed to germs and gets sick, or secondary, in which the body is predisposed to infection due to the main cause.
• Except for mental conditions, some health insurance policies define a medical condition as any ailment, injury, or disease. Because it is more value-neutral than terms like illness, persons with health conditions that they do not deem harmful may prefer the phrase medical condition.
