Hypochondria is a human condition that manifests itself in excessive concern for one’s health and the perception of one’s usual sensations as abnormal. People suffering from hypochondria constantly worry about their health, fear its deterioration, and worry that new diseases may appear or develop. A person is sure that he is sick, despite the absence of objective symptoms or signs of the disease. Personality characteristics such as depression, anxiety, and suspiciousness most often predispose to the development of hypochondria. Its occurrence can also be influenced by environmental circumstances, for example, loved ones who suffer from serious illnesses or excessive care of relatives. One of the effective methods of treating hypochondria is cognitive behavioral therapy. REBT, as a branch of cognitive behavioral therapy, considers irrational attitudes as one of the most important reasons for the development of hypochondria. These may include the following irrational beliefs: Catastrophizing: the belief that even a slight feeling of discomfort may indicate a fatal illness. Tendency to overestimate the likelihood of getting sick. Selective attention: focusing only on physical symptoms while ignoring other information that may refute or contradict the belief. Objectification of symptoms: interpreting various sensations in the body as signs of serious illness, although these sensations may be normal physiological responses to stress or fatigue. Reinforcement of negative beliefs: maintaining negative thoughts by communicating with people who share the anxiety. This approach reinforces the belief that there is indeed a serious illness and that it is impossible to get help from medical professionals. In order to work with hypochondria, it is important to target such attitudes in order to help the person adjust beliefs and reduce anxiety. When working with hypochondria, REBT usually uses a multimodal technique :Changing unrealistic beliefs.Developing strategies to cope with stress, as hypochondria can occur or worsen under conditions of increased stress and anxiety.Identifying the significance of symptoms and helping you understand when to ignore symptoms and when to seek medical help.Setting goals and action planning. An important aspect of this process is planning actions in case symptoms are detected that would cause worry and anxiety. Emotional regulation, to create techniques for solving emotional problems and improving the overall well-being of a person.
