Illness Anxiety Disorder: Symptoms, Causes & Treatments

Listen to this article

Have you ever found yourself excessively worried about your partner’s health, interpreting every minor symptom as a potential sign of a serious illness? Or perhaps you’ve experienced your significant other expressing unrelenting concerns about their own health, despite reassurances from medical professionals. 

These scenarios may not just be instances of overprotectiveness or typical worry. They could be indicative of Illness Anxiety Disorder (IAD), a condition that often goes unrecognized yet can profoundly affect relationships. 

What is illness anxiety disorder in a relationship?

Illness anxiety disorder is a condition where a person worries excessively that they might be or become seriously ill. Even when they have little or no physical symptoms, they are deeply concerned about having a serious disease. 

This worry is so strong that it can interfere with their daily life. They might frequently check their body for signs of illness or visit doctors often, but still not be reassured. 

It’s not just normal concern about health; it’s a constant fear about being sick that doesn’t go away even when medical tests show they are healthy. This disorder can cause a lot of distress and anxiety.

Characterized by a preoccupation with having or acquiring a serious illness, IAD can lead to significant distress and impairment in daily life, including one’s romantic relationships. Understanding the symptoms, causes, and available treatments for IAD is crucial for those navigating these turbulent emotional waters. 

While it’s natural to care for a loved one’s well-being, distinguishing between normal concern and potential signs of Illness Anxiety Disorder is essential in maintaining a healthy, supportive relationship.

What is the difference between illness anxiety disorder and somatic symptom disorder?

Illness Anxiety Disorder (IAD) and Somatic Symptom Disorder (SSD) are distinct psychological conditions. 

IAD, previously known as hypochondriasis, is marked by intense fear of having or developing a serious illness, despite minimal or no physical symptoms. This preoccupation often starts in early adulthood and affects genders equally. 

The primary concern in IAD is the anxiety over the possibility of being sick, not the physical symptoms themselves. 

In contrast, SSD involves actual physical symptoms, such as pain or fatigue, that cause significant distress and are not fully explained by a medical condition. People with SSD are overly anxious about their physical symptoms, believing them to be signs of severe illnesses. 

While the exact cause of IAD is unknown, risk factors include a preoccupation with health and a history of severe illness or health anxiety in the family. SSD is believed to be influenced by a mix of biological, environmental, and psychological factors, including childhood abuse and chronic illness. 

IAD can be chronic, with symptoms lasting for years, but treatment like cognitive-behavioral therapy can improve outcomes.

What are the symptoms of illness anxiety disorder: 9 major signs

Despite having minimal or no physical symptoms, individuals with IAD experience a high level of anxiety about their health. 

This condition can significantly impact a person’s daily life, leading to constant worry and stress over health concerns. Understanding the symptoms of illness anxiety disorder is crucial for recognizing and addressing this condition. Here are nine major signs:

1. Excessive worry about having a serious illness

One of the primary symptoms of illness anxiety disorder is an overwhelming fear of having a serious, often life-threatening illness. This worry persists despite medical reassurance and a lack of symptoms indicative of such illnesses.

2. Regularly seeking medical reassurance

Individuals with IAD frequently visit healthcare providers seeking reassurance about their health. Despite repeated medical evaluations that show no cause for concern, their anxiety remains.

3. Misinterpreting normal bodily functions

People with IAD often misinterpret normal bodily functions or minor physical anomalies as signs of serious illness. For example, a minor headache might be perceived as a sign of a brain tumor.

4. Avoidance of medical information or healthcare settings

Some individuals with IAD may avoid medical information, healthcare settings, or activities perceived as health risks due to their fear of discovering a serious illness. This avoidance can hinder their ability to receive appropriate medical care.

5. Excessive researching of symptoms

Those suffering from IAD may spend significant amounts of time researching health information, particularly about serious diseases, leading to increased anxiety and worry.

6. Impact on daily functioning

The constant preoccupation with health can interfere with daily activities and responsibilities, affecting work, social interactions, and overall quality of life.

7. Seeking frequent tests or procedures

A person with IAD may insist on frequent medical tests or procedures, even when previous results have been normal, in an effort to ensure they are not ill.

8. High levels of stress and anxiety

High levels of stress and anxiety about health are common in IAD. This constant state of worry can lead to other mental health issues, such as depression or generalized anxiety disorder.

9. Strain on personal relationships

IAD can strain relationships as individuals may frequently seek reassurance from loved ones or have their activities and interactions limited by their health concerns.

What causes illness anxiety disorder?

The causes of Illness Anxiety Disorder (IAD) are complex and multifaceted. One significant factor is the misinterpretation of nonpathological physical symptoms or normal bodily functions, such as a racing heartbeat or abdominal bloating, as indications of serious illness. 

This misinterpretation leads to persistent anxiety or fear of having or acquiring a serious illness, which adversely affects daily life. Let’s say, in an illness anxiety disorder example, a person might interpret normal digestive sounds (borborygmi) as a sign of a gastrointestinal disorder.

Another factor contributing to IAD is certain psychological tendencies, such as the expectation of disastrous outcomes (catastrophizing) and a tendency to jump to conclusions despite limited evidence. 

Cognitive-behavioral therapy (CBT) has been shown to help individuals with IAD by teaching them to question these beliefs, examine the evidence, and challenge automatic negative thoughts.

The onset of Illness Anxiety Disorder most commonly occurs during early adulthood and appears to affect men and women equally. Its course can be chronic, fluctuating in some individuals, while others may recover.

How is illness anxiety disorder diagnosed: 5 reliable ways

Diagnosing Illness Anxiety Disorder (IAD) requires careful consideration, as it often involves symptoms that are not easily distinguishable from those of physical illnesses. 

IAD, characterized by an excessive preoccupation with having or acquiring a serious illness, poses unique challenges for healthcare providers. The diagnosis hinges on differentiating between normal health concerns and the pathological worry seen in IAD. Here are five reliable ways in which IAD is diagnosed:

1. Detailed patient history

A thorough patient history is crucial. This includes exploring the patient’s medical background, previous diagnoses, and treatments. The focus is on identifying patterns of health-related concerns and behaviors. For instance, a history of frequently changing doctors or repeatedly seeking medical tests for the same symptoms can indicate IAD.

2. Psychological evaluation

Psychological evaluation helps assess the patient’s mental state, focusing on their thoughts, feelings, and behavior patterns related to health. This evaluation can reveal if their concern about illness is excessive or disproportionate to the likelihood of having a serious health condition.

3. Rule out physical health conditions

It’s essential to rule out any actual physical health conditions that could explain the symptoms. This involves comprehensive medical tests and examinations. If results consistently show no underlying medical cause for the patient’s health concerns, it might suggest IAD.

4. DSM-5 criteria for IAD

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), provides specific criteria for IAD diagnosis. These criteria include a preoccupation with having or acquiring a serious illness, high levels of anxiety about health, and excessive health-related behaviors or maladaptive avoidance.

5. Observation of symptom duration

For a diagnosis of IAD, symptoms must persist for at least six months. This duration helps differentiate IAD from transient health anxieties that might occur in response to actual medical conditions or life stresses. 

The persistent nature of the anxiety, despite reassurance and negative medical findings, is a key indicator of IAD.

What are the treatments for illness anxiety disorder: 7 options we have

Treating Illness Anxiety Disorder (IAD) involves a combination of psychological and sometimes pharmacological interventions aimed at reducing the distress and preoccupation associated with health-related anxieties.

The treatment of illness anxiety disorder focuses on helping patients manage their fears and improve their quality of life. Here are seven options available for addressing IAD:

1. Cognitive-Behavioral Therapy (CBT)

CBT is a cornerstone in the treatment of illness anxiety disorder and probably the best answer to how to overcome illness anxiety disorder. 

It helps patients identify and challenge irrational beliefs and catastrophic thoughts about their health. Through CBT, individuals learn to replace these thoughts with more realistic and balanced ones, reducing anxiety and improving coping skills.

2. Regular medical follow-up

Establishing a consistent and trusting relationship with a primary healthcare provider can be beneficial. Regular follow-ups allow for health concerns to be addressed promptly and reduce the patient’s need to seek multiple opinions, thus minimizing unnecessary medical investigations.

3. Medication

While there’s no specific medication for IAD, certain medications like antidepressants (particularly SSRIs) can be effective, especially when symptoms of anxiety or depression are present. These medications help to alleviate underlying mood or anxiety symptoms that may contribute to IAD.

4. Mindfulness and stress reduction techniques

Practicing mindfulness and stress reduction techniques can help patients manage anxiety more effectively. Techniques like meditation, deep breathing, and progressive muscle relaxation can provide immediate relief from acute anxiety symptoms.

5. Psychoeducation

Educating patients about their condition is vital. Understanding what IAD is, how it affects them, and the role of anxiety in perpetuating their symptoms can empower patients and motivate them to engage in treatment.

6. Group therapy

Participating in group therapy can provide social support and validation from others experiencing similar challenges. It can also be a platform for sharing coping strategies and gaining insight into how to overcome illness anxiety disorder.

7. Lifestyle modifications

Encouraging patients to adopt a healthy lifestyle, including regular exercise, a balanced diet, and adequate sleep, can improve overall well-being and help mitigate anxiety symptoms. These modifications can enhance the patient’s ability to cope with stress and reduce the intensity of IAD symptoms.

Each of these treatment options can be tailored to the individual’s needs, and often a combination of these methods yields the best results in managing IAD.
