Understanding Chronic Illness and Disability, Their Differences, and How to Get Support

Living with a chronic illness can be a challenging and life-altering experience. Chronic illnesses impact more people than you can imagine, as the CDC reports that nearly 6 in 10 American adults suffer from at least one chronic illness while 4 in 10 have two or more chronic illnesses.

These chronic diseases affect millions of people worldwide, yet there is often confusion surrounding what constitutes a chronic illness versus a disability, as some chronic illnesses can eventually lead to a disability.

So this leads to the main question: How can you tell the difference?

Chronic Illness: A Prolonged Health Condition

A chronic illness is a prolonged health condition that typically lasts for over a year and can lead to difficulty in performing daily activities. These conditions can range from mild to severe and may affect various bodily processes.

Common examples of chronic illnesses include:

  • Diabetes: A metabolic disease characterized by high blood sugar levels.
  • Cancer: A disease in which abnormal cells divide uncontrollably and damage body tissue.
  • Hypertension: Chronic high blood pressure.
  • Asthma: A respiratory condition causing airway inflammation and difficulty breathing.

Chronic illnesses often require ongoing treatment, medication, lifestyle adjustments and regular medical appointments. While these conditions can significantly impact your quality of life, they may not always result in disability.

Disability: Impairments that Limit Functionality

A disability refers to a physical or mental impairment that substantially limits one or more major life activities. Disabilities can be present from birth, acquired due to illness or injury, or develop over time. Disabilities are diverse and can manifest in various ways, including:

  • Mobility Impairments: Difficulty walking or using limbs.
  • Visual Impairments: Partial or total vision loss.
  • Hearing Impairments: Partial or total hearing loss.
  • Intellectual Disabilities: Limitations in cognitive functioning and communication.
  • Mental Health Disabilities: Conditions like depression, anxiety, or post-traumatic stress disorder (PTSD).
  • Neurological Disabilities: Conditions like multiple sclerosis (MS) or cerebral palsy.

A disability can impact someone’s life in various ways, from minor inconveniences to significant barriers in daily activities, employment, social engagement and even receiving health care. Luckily, the Americans with Disabilities Act (ADA) has protections set in place to accommodate people living with disabilities.

Now that you know the meanings of both health conditions, here are some ways to help you better identify the key differences between chronic illness and disabilities:

  • Duration: The primary distinction is the duration of the condition. Chronic illnesses are long-term health issues, while disabilities can be either long-term or permanent.
  • Functional Impact: Chronic illnesses may impact a person’s health and well-being but may not necessarily limit their functionality or independence. Disabilities, on the other hand, often result in significant limitations in one or more life activities, in turn, limiting their independence.
  • Origin: Chronic illnesses often result from underlying health conditions as well as genetics, while disabilities can stem from various factors, including genetics, accidents or injuries.

Sometimes, a disability can even result from a chronic illness, but that is not always the case. With this in mind, chronic illnesses and disabilities should not be synonymous with one another, as they can often stem from different things.

If your chronic illness feels like it is starting to become a disability, your condition might be debilitating your social life, your daily functions, your activity, your mental health, and most importantly, your independence.

Seeking Support for Chronic Illnesses and Disabilities

Both chronic illness and disability can benefit from various forms of support and resources. While people with chronic illnesses may not need the same level of support as someone with a disability, it is still a good way to care for the person in case the illness becomes a disability in the future.

Here are some ways to effectively care for people with chronic illnesses and disabilities:

  • Medical Care: Regularly consult with healthcare professionals for diagnosis, treatment and management of chronic illnesses or disabilities. Follow prescribed treatments and therapies. For people with disabilities, a more hands-on approach may be needed to assist them with activities of daily living.
  • Support Groups: Join support groups, both online and in-person, to connect with others facing similar challenges. These groups offer emotional support, advice, and a sense of community, even for those facing minor chronic illnesses.
  • Rehabilitation Services: For people with disabilities, consider rehabilitation services such as physical therapy, occupational therapy, or speech therapy, depending on their specific needs.
  • Assistive Devices: Utilize assistive devices and technologies designed to enhance independence and accessibility, like mobility aids, hearing aids, or screen readers.
  • Home Care: Being at home provides a familiar and comfortable environment, reducing stress and anxiety for people with disabilities. Consider hiring a home caregiver to help out with daily activities.
  • Understanding Legal Protections: Familiarize yourself with disability rights and legal protections in your region, such as the Americans with Disabilities Act (ADA) in the United States, to ensure equal opportunities and accommodations.

SYNERGY HomeCare believes it is important to understand the differences between chronic illnesses and disabilities, as they can often be used interchangeably when they have clear distinctions.
