Published: Last Updated on

The Definition of functional disease encompasses all physical disorders with signs and symptoms typical of an organic disorder or disease in the medical literature. Still, if a deep examination is made, no trace of the existence of any structural or physical abnormality is discovered. They are maybe causing it.

But beyond technicality, if you want to learn more about functional diseases and the difference between these and organic diseases, some of the most frequent functional disorders, in this FastlyHealarticle, we will explain them to you.

Organic disease

In the introduction, we said that functional diseases present the symptoms of organic disorders without appreciating changes in the changes or abnormalities in the body, but what is an organic illness?

Currently, any medical pathology is classified as organic when the symptoms that the patient notices and suffers are accompanied by an organic lesion or an identifiable physiological alteration. From any medical specialty, a great variety of examples of diseases of this type can be given; at the digestive level, peptic ulcer, esophagitis, or appendicitis are conditions with lesions in any of the parts of the digestive tract that can be located and noticed, to At the cardiac level, anatomical abnormalities that produce a myocardial infarction or valve defects can be seen.

We can also find diseases such as lactase deficiency malabsorption syndrome or other digestive intolerances within this classification. There is no type of anatomical lesion that can be observed. Still, there are physiological alterations at the biochemical or metabolic level.

Functional disease

Unlike organic diseases, in which they have a functional origin, we cannot observe any alteration, either anatomical or biochemical, that can serve as a justification for the symptoms suffered by the patient.

It is widespread that when a physical reason is not found to justify the disease, the emergence of these symptoms is associated with a psychological origin. This type of so-called functional disease has manifested itself the most in gastrointestinal disorders and digestive tract problems.

Symptoms such as chest pain of non-cardiac origin, irritable bowel syndrome, or dyspepsia are widespread examples of diseases in which no injuries or alterations can serve as justification for their head.

But not only in what refers to the digestive system, but we also find examples of this type of affection; in the case of primary arterial hypertension, no apparent cause is observed that could give it an origin; the same happens with many headaches or headaches.

These so-called functional disorders are usually associated with psychosomatic or psychological symptoms. But not all available diseases have to be currently; many diseases are included in this category, perhaps in excess, associating them with emotional factors such as stress or anxiety, when indeed, with a deeper exploration, the natural causes could be identified that affection or simply a cause is not found because we still do not know it.

Type X factors

We speak of type X factors when the determining factors that can cause disease are not yet known, so it may be that a condition is classified as functional when what is happening is that there is a type X factor behind it.

Years ago, for example, it used to be diagnosed as functional diarrhea, which was lactase malabsorption, something that we can now analyze.
