Comorbidity: Types, Prevalence, Treatment


Comorbidity is the presence of two or more conditions that occur in one person simultaneously or sequentially (a condition that occurs immediately after the other). Conditions described as comorbidities are often long-term (chronic) conditions.

When two or more diseases or conditions occur simultaneously or sequentially, it is also called comorbidity. Other names for comorbid conditions include comorbid conditions, coexisting conditions, and, less frequently, multiple chronic conditions, as well as multimorbidity.

According to a study published in the journal Annals of Family Medicine. “Comorbidity is associated with poorer health outcomes, more complex clinical treatments, and higher health care costs.”

There are many different possibilities for comorbidities, from coexisting mental illness and drug abuse to comorbidities such as diabetes and high blood pressure. Comorbidity may include physical illness and mental illness (e.g., cancer and major depressive disorder).

There are many diseases that tend to combine with others for a variety of reasons. Perhaps the risk factors are the same for two specific diseases, so a person is more likely to get each.

In addition, symptoms of a disease can predispose one person to another. For example, anxiety often makes a person more likely to self-medicate with drugs or alcohol.

Common Companions Disease

These conditions have common comorbidities.


Obesity is known to predispose people to many comorbidities. In fact, according to the obesity medicine association, there are about 236 medical problems (including 13 types of cancer) related to obesity. Common comorbidities for those who are obese include:

  • Insulin resistance: a condition that is considered a precursor of type 2 diabetes
  • Type 2 diabetes
  • Hypertension: High blood pressure
  • Dyslipidaemia: High levels of lipids in the blood, such as high cholesterol
  • Cardiovascular diseases
  • Cerebral haemorrhage
  • Arthritis
  • Apnea in sleep: a sleep disorder in which breathing stops repeatedly for short periods of time.
  • Gallbladder disorders: such as gallstones or cancer
  • Hyperuricaemia: High level of uric acid and gout
  • Osteoarthritis: Degenerative joint disease
  • Some types of cancer: such as breast and colorectal cancer, as well as gallbladder cancer
  • Slump

Examples of factors involved in the development of comorbidities in obese individuals include:

  • Physical / metabolic stress that can cause negative effects on many organs in the body (such as the heart and kidneys)
  •  Biomechanical stress caused by exposure to excess weight can lead to comorbidities such as osteoarthritis 
  • Biomechanical forces that can cause weight gain pressure the rib cage and diaphragm, this can cause destruction of the soft tissues of the neck (leading to sleep apnea)
  • Increased hormones and other substances released by adipose (adipose) tissue, which affects the endocrine system, can lead to diabetes and other metabolic conditions


Common conditions (comorbidities) associated with diabetes include:

Psychiatric Escorts Disease

According to the 2018 Administration of Mental health and Substance abuse services (SAMHSA) national drug use and health survey, nearly 9.2 million adults in the United States have a comorbidity that includes substance abuse and mental illness or two types of mental illness such as anxiety and depression.

Comorbid Disorders

Substance use disorder may include alcohol or drug dependence (or both). Substance use-related comorbid disorders and mental illness are common (also called comorbid disorders, dual diagnosis and less commonly called MICD (mental illness / chemical dependence).

When it comes to substance use-related comorbid disorders and mental illness, the National Institute on drug abuse reports that nearly half of those who have one condition, whether mental illness or substance abuse, also have another.

In the 1980s, a double diagnosis was initially established, but over time, BOJSHA decided to use the term comorbid disorders (COD) for comorbidities in the field of mental health. People with a comorbid disorder have one or more substance-related disorders along with one or more psychiatric disorders.

People with substance use disorders are more likely to have mental illness, and people with mental illness are more likely to have substance use disorders. This is not necessarily due to the fact that the symptoms of each disorder cause a comorbidity in a person.

Chances are that the risk factors are the same for substance abuse and mental health disorders, which predisposes a person with either disease to have both. In addition, some symptoms of a substance use disorder can cause people to self-medicate (use drugs or alcohol).

A third factor that explains why comorbid disorders are so common when it comes to mental illness is that chronic (long-term) use of drugs or alcohol can negatively affect the brain, increasing a person’s chance of developing a mental illness.

Depression and anxiety

One of the most common examples of comorbidity in the field of mental health is depression and anxiety disorder. According to the national alliance on mental illness (Nami), some sources estimate that nearly 60% of people with anxiety also have symptoms of depression and vice versa.

Some of the most common mental health disorders in people with substance use disorders include mood disorders and anxiety, such as:

Mood disorders:

  • Deep depression
  • Dysthymia
  • Bipolar disorder

Anxiety disorders:

  • Post-traumatic stress disorder
  • Panic disorder
  • Social anxiety
  • Generalized anxiety disorder
  • Obsessive-compulsive disorder

People with conditions considered severe and persistent mental illness (PMI) have the highest risk of mental health disorders and concomitant substance use. Diagnoses of PMI, sometimes called thought disorders, include:

  • Schizophrenia
  • Schizoaffective disorder (a chronic disorder that includes hallucinations, delusions, and symptoms of a mood disorder.)


The most important thing to remember about treatment when it comes to comorbidities is that it often requires advice and planning between different health professionals and organizations. This applies to people with multiple mental disorders, as well as people with concomitant physical illnesses.

After hospitalization, people with numerous health problems often need the help and support of organizations such as home health institutions and social services to meet needs such as inability to work due to a severe disability, the need for housing, physical care and more.

When it comes to comorbid disorders in people with severe and persistent mental illness (SPMI), it is often a revolving door between treatment facilities, behavioral health-related hospitalizations, home discharge, and then return to treatment or readmission.

A Few Words From Get Meds Info

Comorbidity involves more than one diagnosis at a time or two or more diseases that occur back to back. There are many different causes of comorbidity. There may be a possibility that a person has a comorbidity.

Risk factors for certain types of diseases overlap, and these independent risk factors often affect each condition when a person has a comorbidity. These are called ” superimposed risk factors”. Another possibility is that one disorder actually causes another.

It’s important to note that while you may have a condition that is usually associated with other specific conditions or symptoms (such as high blood pressure), this does not necessarily mean you are diagnosed with a comorbidity.

Frequently asked questions

  • Comorbidity is the presence of two or more diseases that exist simultaneously and independently of each other. An example is diabetes e ischemic disease heart.

  • In comorbidity, two or more comorbidities develop independently, even if there may be common risk factors. A complication is an adverse event that occurs as a direct consequence of a disease such as diabetic kidney disease in people with diabetes 2 type o AIDS-dementia of HIV-infect.

  • The Charlson comorbidities index is a system used to predict mortality in people with comorbidities to determine how aggressively a particular disease should be treated. Each comorbidity is classified on a scale of 1 (e.g., in diabetes) to 6 (e.g., in metastatic cancer) and then summarized to get a final estimate.

  • In psychiatry, comorbidity is the presence of one or more diagnoses (such as obsessive-compulsive disorder and eating disorder). However, because the diagnosis of mental disorders is based on criteria rather than medical tests, comorbidity does not always mean that there are several diseases, but that a single diagnosis cannot explain all the symptoms.
