While the key differences between somatic symptom disorder vs illness anxiety disorder may not be very obvious, it's important to know them for diagnosis and treatment. From time to time, all of us are concerned and worried about our health.

However, what if this worry becomes too overwhelming and hinders our everyday lives? Somatic symptom disorder and illness anxiety disorder are the two common disorders that involve excessive health worries and can be extremely challenging to live with.

It's important to note that both conditions are distinct in their focus. While SSD is associated with physical symptoms that cannot be explained, IAD revolves around the persistent worry of having an acute illness.

They pay a lot of attention to these physical signs, resulting in distress and suffering.

  • Individuals suffering from SSD have very real physical signs.
  • There isn't a known medical condition that fits these symptoms.
  • The focus on these signs leads to feelings of intense distress and worry.

A major point of difference between somatic symptom disorder and illness anxiety disorder is what individuals pay attention on. In the case of SSD, the attention is on real physical signs, even in the absence of a clear medical explanation.

In the case of IAD, the attention is primarily on the fear of having a deadly disease or illness, typically because of minor symptoms which most individuals aren't concerned about.

While both lie on the continuum of health anxiety, they affect individuals differently. Perhaps the most common differentiating factor is their behavior.
