Agoraphobia and the hyperventilation syndrome

One of the causes of agoraphobic complaints is the fear of having an attack of physical complaints in public places. The Hyperventilation Syndrome (HVS) with its diverse symptoms seems to fit well in this model. Hyperventilation symptoms are threatening, because for most subjects they occur unexpectedly and without a clear reason. An investigation was made into how often the HVS and the agoraphobic syndrome appeared together and into the causal relationship between both syndromes. About 60% of the agoraphobic patients suffered from hyperventilation complaints and about 60% of the HVS patients were agoraphobic. Most patients mentioned the fear of having an attack as an important reason for their agoraphobic complaints, and this applied especially in the case of the HVS.
