Understanding OCD and Health Anxiety

OCD, or Obsessive Compulsive Disorder, is a mental health condition that affects many around the world. People who suffer from OCD have persistent and uncontrollable thoughts or obsessions, and as a result, they engage in compulsive behaviours in order to alleviate these obsessive thoughts.

Health anxiety, on the other hand, is a form of anxiety whereby an individual experiences persistent and intense worry about their health. They may frequently check their body for signs of illness, or constantly seek reassurance from healthcare providers. While health anxiety is not necessarily associated with OCD, it can be a component of it. In this article, we’ll further explore the relationship between OCD and health anxiety, and how it can be treated.

Symptoms of OCD

OCD is characterised by the presence of unwanted and intrusive thoughts, images, or impulses, known as obsessions. These obsessions can take on many different forms, such as fear of contamination, doubts over one’s own morality, or even a need for things to be arranged in a specific way. The individual then feels compelled to carry out certain behaviours or mental acts, known as compulsions, that could relieve the anxiety caused by the obsessions. For instance, an individual with a contamination obsession may excessively wash their hands or clean their home, even if they’re already clean.

These compulsions, however, often do not provide long-lasting relief, and may even cause further anxiety, leading to a vicious cycle of obsessive thoughts and compulsive behaviours, which can significantly affect an individual’s quality of life.

Symptoms of Health Anxiety

Health anxiety, also known as hypochondriasis or illness anxiety disorder, is characterised by excessive worry and fear about one’s health, even when there is little or no evidence of a serious illness. Those who suffer from health anxiety may frequently check their body for signs of illness, such as lumps or rashes, and may also consult health professionals frequently for reassurance.

Individuals with health anxiety may also engage in behaviours such as avoiding certain foods, limiting social contact or travel, and using excessive hygiene measures, for instance, by wearing a mask even when they are not at risk for infection.

How OCD and Health Anxiety are Related

While OCD and health anxiety are two distinct conditions, they share some common features. Both are characterised by persistent and intrusive thoughts, leading to compulsions or behaviours that can provide temporary relief. In the case of health anxiety, for instance, an individual may feel compelled to check their body for symptoms, leading to a temporary reduction in anxiety.

Furthermore, both conditions can significantly impact an individual’s quality of life. For those with OCD, the intrusive thoughts and compulsive behaviours can prove difficult to control, affecting their ability to work, socialise, or maintain relationships. For those with health anxiety, the constant worry and fear can lead to significant stress and anxiety, and may result in avoidance behaviours that can further isolate them from social interactions.

Treatment for OCD and Health Anxiety

Fortunately, effective treatments are available for both OCD and health anxiety. The most common treatments for OCD are therapy and medication. With therapy, individuals with OCD can learn to identify and manage the thoughts and behaviours that trigger their compulsions. Cognitive Behavioural Therapy (CBT) and Exposure Response Prevention (ERP) are often used as effective forms of psychotherapy for OCD. Both approaches involve gradual exposure to the feared situations, and gradually reducing the need for a compulsive behaviour.

Medications, such as selective serotonin reuptake inhibitors (SSRIs), can also be effective in treating OCD. These medications work by changing the balance of neurotransmitters in the brain, leading to a reduction in the symptoms of OCD.

For health anxiety, CBT is often the first line of treatment. During CBT, individuals can learn to recognise the thought patterns that are contributing to their anxiety, and develop coping strategies to manage these thoughts. They may also engage in relaxation techniques, such as meditation or mindfulness, to help alleviate their anxiety.

Ultimately, both OCD and health anxiety can be effectively treated with a combination of therapy and medication, allowing individuals to regain control over their thoughts and behaviours and lead a more fulfilling life.


OCD and health anxiety are two mental health conditions that can significantly affect an individual’s quality of life. While they are distinct conditions, they share some common features, such as persistent and intrusive thoughts, leading to compulsions or behaviours that can provide temporary relief.

The good news is that effective treatments are available for both conditions. By combining therapy and medication, individuals with OCD and health anxiety can learn to manage their symptoms and regain control over their lives. If you or someone you know is struggling with OCD or health anxiety, know that help is available, and reaching out for support can be the first step in the path towards recovery.


FAQs about OCD and Health Anxiety

What is OCD?

Obsessive-Compulsive Disorder (OCD) is a mental health condition characterized by unwanted, intrusive thoughts and repetitive behaviors or mental rituals to alleviate anxiety. These rituals can occupy significant amounts of time and interfere with daily routines, causing significant distress.

What is Health Anxiety?

Health Anxiety, also known as Illness Anxiety Disorder, is a condition where an individual experiences persistent and excessive fears about their health, despite reassurance from doctors and medical tests showing no serious medical condition. This anxiety can lead to avoidance of medical appointments and procedures, which can have adverse effects on physical health.

How are OCD and Health Anxiety related?

Many people with OCD also experience health anxiety, as they may obsess over bodily sensations or symptoms, leading them to believe they have a serious illness. This can trigger compulsive behaviors, such as seeking reassurance from doctors or constantly checking their bodies for signs of illness. Treatment for OCD and health anxiety often overlap, with cognitive-behavioral therapy and medications being effective options for both.
