What is the true definition of a Chronic Illness?
Further to that, does the most basic definition really capture the widespread severity of long-lasting illnesses.
Click here for a link to an article that discusses the various definitions of chronic illness and the implications of having so many different meanings and understandings of this term. This link also discusses the differing definitions explained on various websites, including MedicineNet and Oxford Dictionaries.
Excerpts from the first link:
'Another academic study on chronic disease, authored by a geriatrician, classifies chronic illness as “conditions that last a year or more and require ongoing medical attention and/or limit activities of daily living”'
'The World Health Organization states that chronic diseases,
are not passed from person to person. They are of long duration and generally slow progression. The four main types … are cardiovascular diseases (like heart attacks and stroke), cancers, chronic respiratory diseases (such as chronic obstructed pulmonary disease and asthma) and diabetes'
And criteria listed from another site:
'complex causality, with multiple factors leading to their onset
a long development period, for which there may be no symptoms
a prolonged course of illness, perhaps leading to other health complications
associated functional impairment or disability'
Other definitions describe chronic illness as anything lasting 3 months or longer, in direct opposition to an acute illness.
So would you call a 6 month long stint with mono 'chronic mono'? Or a broken leg taking longer than 3 months to heal 'chronic bone fractures'? There are times when utilizing the term 'chronic disease' is done too liberally.
So what is my understanding of a chronic illness?
What are definitions on various medical sites of chronic illness?
And is putting the word 'chronic' in front of an already understood lifelong disorder - like 'chronic asthma' redundant?
So how do we know what is truly considered a chronic illness.
With so many definitions, the meaning can be lost.
My understanding of a chronic illness is a disease that requires constant medical care, is incurable as we know now, and is a lifelong disease that has fluctuations in severity but will never go away, and affects an individual's ability to function normally in daily life. This includes both physical and mental illnesses.
Some definitions contradict what I have learned. Some definitions point out that the only real chronic illnesses include cancer, respiratory diseases (like asthma and COPD), diabetes, and arthritis.
Other definitions include *everything* - medical or otherwise - that lasts longer than three months. Various links even suggest the use of the term with behaviours - like chronic nail biting, chronic exercising, or a classroom being chronically overcrowded. With medical terms it has even gone so far as having a chronic sprain, chronic acne, or a chronic sunburn.
In my opinion, the overuse of this term, and the lack of consensus on what the true definition of chronic illness is, results in trivializing those who do suffer with chronically painful diseases.
This type of overly used terminology can lead to discrediting those who truly suffer - very much in the same way that over-diagnosing illnesses like Lyme Disease or Fibromyalgia (when the cause of the patient's suffering just cannot be narrowed down immediately) leads to a general disbelief in the diagnosis itself - even though the diseases are very real.
So how do we decide the true definition of chronic illness?
If we look at particular diseases/disorders, like Chronic Migraines, there is a specific set of criteria that must be met. According to neurosurgeons and various societies dedicated to migraines and severe headaches, a patient must suffer at least 15 migraines a month for a period of at least three consecutive months in order to be considered a chronic migraine sufferer.
With a disease like Chronic Pouchitis (which sounds made up, I know), the constant inflammation of a J-Pouch (created with the small intestine after the removal of the large intestine) has to last for more than 6 months. In addition, Chronic Pouchitis is diagnosed when medications have been ultimately unsuccessfully in driving out the inflammation.
What about Inflammatory Bowel Diseases? What about lifelong Hereditary diseases - like Huntington's Disease? Does a disease need to be severe or potentially terminal to be considered chronic? Does an illness have to be considered incurable or a lifelong disease to be termed chronic? Or does a chronic illness simply refer to any symptom lasting more than 3 months?
In my opinion, we need to be very careful in regards to what illnesses we call chronic.
Just like using umbrella syndrome definitions results in the minimalizing of those who truly suffer, using the term 'chronic' for anything that causes discomfort for a few weeks will result in more patients having to fight to be believed.
