What is a chronic illness?

Chronic Illness Definition

A chronic illness (sometimes known as a chronic disease, or chronic condition) is a long-term medical condition. These illnesses cannot normally be prevented by vaccinations, or cured completely with medical treatment. The NHS refers to chronic illnesses as long term physical health conditions.

Chronic illnesses are often non-communicable diseases, but this isn’t necessarily the case. For instance, HIV falls under the umbrella of chronic illness due to its long-lasting effects, but it can also be passed from person to person.

Chronic conditions become more common with age, with approximately 80% of adults over 65 having at least one chronic illness, and 77% having two or more conditions.


Acute Illness Vs Chronic Illness - What's the difference? 

Acute illnesses and chronic illnesses are both terms used to describe medical conditions. Both sound serious, but these terms actually refer to the length of the onset and overall duration of an illness.

Chronic conditions are long-term in every sense of the word. They develop slowly and symptoms often get worse over time. They can't normally be fully cured.

Acute conditions come on much more suddenly, but only last a few days or weeks – for instance, infections, broken bones and other injuries.

Types of Chronic Illness

Chronic illness is a huge spectrum, covering a wide range of symptoms and conditions. Here are just a few chronic conditions you’ve probably heard of:

  • Hypertension
  • Arthritis
  • Coronary heart disease
  • Diabetes
  • Chronic kidney disease
  • Depression
  • Alzheimer's disease and dementia
  • Asthma
  • Epilepsy
  • Stroke
  • Cancer​​​​
  • Crohn's disease
  • Parkinson's disease​​​​
  • Cystic fibrosis
  • Chronic fatigue
  • Multiple sclerosis
  • High cholesterol

All in all, chronic illnesses account for 71% of deaths worldwide, with cancers, heart disease, stroke and diabetes the leading causes of death.

Is Chronic Illness a Disability? 

There’s often an overlap between chronic conditions and disability. A disability is classified as any physical or mental impairment that has a substantial or long term negative effect on a person’s ability to do normal daily activities.

 Many chronic illnesses easily fall under this umbrella and this is something that’s taken into account by law. For instance, people who are diagnosed with the chronic conditions HIV , cancer or multiple sclerosis automatically meet the UK’s disability definition on the day of diagnosis. Moreover, many other chronic conditions have a detrimental and disabling effect on daily activities. For example, a painful arthritis flare-up might make it hard to get out and about, or mean that it's difficult to do things like cook for yourself.

That said, it’s worth mentioning that not everyone with a chronic condition will identify as having a disability, and not all people with disabilities have a chronic illness.

Coping With Chronic Illness

Stages of Coping with A Diagnosis 

If you’ve just been diagnosed with a chronic condition, it’s normal to feel scared, sad and overwhelmed. It can be distressing to think about the long-term effects of a chronic illness, or to consider the changes and adjustments you might have to make to your lifestyle to manage the condition properly.  Depending on the illness, you might even feel guilty or ashamed. This tends to be more common with “preventable” conditions such as Type 2 diabetes.

The Five Stages of Grief can be a useful framework to help you to understand the emotions you might experience if you've just received an unwanted diagnosis. Remember that you won't necessarily experience all these stages, or experience them in the order listed here.

  • Denial: At first, you might not believe the diagnosis due to the shock. This may help you to handle the news, but it's important that you confront the diagnosis eventually so that you can take action and manage your condition properly.  
  • Anger: It's perfectly normal to feel very angry and frustrated when you're diagnosed with something scary. You might be angry at yourself, medical professionals or even your friends and family. You might just be angry at the world generally and at the way things have turned out. Talking through your anger and negative feelings with loved ones can help you to cope with this. 
  • Bargaining: With medical conditions, this often takes the form of "if only" statements. "If only I'd done this, I wouldn't have got...." . You might also plan ways to prevent a chronic condition progressing further, or make internal bargains like changing your lifestyle and behaviours "in exchange" for recovery. Thoughts like these can feel like a way to regain control over your situation. However, it's also very easy to get stuck in a negative spiral of self-blame and anxiety when you think like this. 
  • Depression: We'll discuss this in greater depth later in the article, but this stage is just what you'd expect. You might experience feelings of hopelessness, sadness and despair at the lot you've been given. You might feel like isolating yourself, or just feel numb. 
  • Acceptance: Eventually, you will come to terms with your illness. You'll learn to cope with it as a new normal and get on with your life. This might also be the point you start realising the best ways to manage your illness and begin to feel more positive overall. 

All these emotions, and the physical toll of the condition itself, can make coping with chronic illness very challenging.

Coping Strategies for Chronic Illness

Having a solid support network, knowing the best ways to manage your health and practising self-compassion will all help you during more difficult times.

Building your support network

When you're ill, it can be tempting to isolate yourself from friends and family. We've put together these tips to help you keep your support network in place, and even grow it.

  • Stay connected – having a solid support network that you can rely on will make coping with a chronic illness far easier. Don't be afraid to ask your loved ones for help when you need it.
  • Join a support group for people with your illness. It can help to speak to people who are experiencing the same things as you and know that you’re not on your own.
  • ​​Understand your limitations and don't be afraid to say 'no'. Depending on your illness, some activities may become more difficult than they were before. If you're not up for something suggested by a friend or family member, trust your instincts. They'll understand!

Managing Your Health

Naturally, a new diagnosis will bring with it lifestyle changes. You might have to put more effort into managing your health in order to keep your condition under control. Here are some ways to make that easier:

  • Find a doctor that you trust, who will answer questions about your condition honestly and openly.
  • Get informed. If you’ve recently been diagnosed, learning as much as you can about your condition, its progression, and possible treatments will empower you and help you to make informed decisions.
  • Live as healthily as possible. Treating chronic conditions normally involves a lifestyle change, whether that’s giving up smoking, eating more healthily or losing weight. If you can make these changes, you’ll find your condition much easier to manage and feel better overall.
  • Get organised: There's a chance that you'll be taking a lot of medication to manage your condition. Find ways to organise yourself so that you don't forget to take it. For instance, a pill dispenser box can help you to remember to take the right pills each day. Also remember to talk to your doctor about what time of day and the right way to take your medicine.

Self-Care and Compassion

  • Try to keep doing the things you enjoy. If your hobbies have become more difficult as a result of your illness, consider ways that you can modify them to make them more manageable, rather than giving them up all together.
  • Be kind to yourself: It's easy to hate your body and think of it as an enemy when you're unwell. Try to treat yourself with the same compassion you'd give to a friend or family, rather than blaming yourself or your body for your health problems.
  • Remember it's fine to have bad days. Be prepared for days where you don't even feel like getting out of bed. Chronic illness is mentally and physically draining, so don't punish yourself for days where you're finding it more difficult to cope.

Chronic Illness & Mental Health

It’s clear that chronic illness can have a profound emotional toll, as well as a physical one. Being diagnosed with a life-changing (or even life-threatening) illness is a lot to take on board and understandably affects many people psychologically. In some cases, this distress can bring on mental health conditions such as depression, anxiety and PTSD.

Depression and Chronic Illness

There’s a big link between depression and chronic illness. In fact, depression is considered a common complication for people with long-term medical conditions, with up to a third of people with chronic illnesses experiencing symptoms. This may also come hand in hand with anxiety.

 It’s easy to see why this is – chronic illness can affect your ability to do things you enjoy, which can lead to feelings of despair and a loss of self-confidence. Painful symptoms, loss of mobility and even medication used to manage a condition can also exacerbate feelings of depression.

The following chart shows the chance of experiencing depression for different chronic conditions:

Depression is itself a chronic condition, and living with both this and another illness can be incredibly exhausting.

Remember that you don’t have to go it alone though; if you’re experiencing symptoms of depression, we urge you to seek help. It’s easy to just see feeling sad as part of your condition, but that doesn’t have to be the case, and depressive symptoms shouldn’t be overlooked simply because you’re ill anyway.

Mental and physical health are dependent on each other, and improved wellbeing will do wonders for your health overall.

How to cope with depression

  • Consider seeing your doctor. Medication and psychotherapy are both effective ways to treat and manage depression.
  • Spend time with friends and family. It’s easy to feel alone if you have a chronic illness, but isolating yourself can make feelings of hopelessness worse.
  • Consider a change of medication. Certain medicines used to treat chronic illnesses can destabilise your mood. If mood changes are a known side effect of what you're taking and you feel depressed, ask your doctor if there are alternative treatments that you can try. 
  • Make sure you’re receiving the right level of pain management. If your condition causes painful symptoms, make sure your doctor is addressing that pain properly. It probably won't surprise you, but pain can seriously lower your mood. 

Post Traumatic Stress Disorder (PTSD) 

PTSD is a psychiatric disorder that can affect people who’ve experienced or witnessed a life-threatening event. Symptoms include:

  • Reliving traumatic events via flashbacks, nightmares and negative thoughts.
  • Trying to avoid being reminded of a traumatic event.
  • Emotional numbing
  • Anxiety and hyperarousal
  • Phobias
  • Physical sensations such as pain, sweating and nausea

Post traumatic stress disorder is commonly associated with military service, but in reality any type of trauma can trigger this condition. This includes trauma as a result of chronic illness – for instance, from being diagnosed with a life-threatening condition like cancer, or having to endure repeated surgeries. Other symptoms, such as chronic pain, can also give rise to PTSD due to the way they impact quality of life.

If you think you’re experiencing post traumatic stress disorder, contact your doctor to discuss treatment options. The main treatments are likely to be psychotherapy, such as cognitive behavioral therapy (CBT), and medication.

For PTSD, trauma-focused CBT is normally used. This will help you to gain control of your fear and trauma by thinking about your experiences in detail and talking them through with your therapist.
