Health worries and bodily symptoms can have many possible explanations. A guide cannot determine whether symptoms are anxiety related, replace medical assessment or prescribe a self help plan. New, severe, persistent or concerning symptoms need appropriate medical assessment rather than being assumed to be caused by anxiety. Health anxiety can involve heightened attention to bodily sensations, repeated searching, reassurance seeking, checking, avoidance or difficulty tolerating uncertainty. These patterns do not establish a diagnosis and may also be influenced by physical health, medication, past illness, family experiences, bereavement, trauma, current stress or an understandable need for clarity. Assessment can consider both the health concern and its impact on daily life. CBT based support may be considered after individual assessment alongside appropriate medical advice. Any work on checking, reassurance, attention or uncertainty should not involve delaying or avoiding necessary medical care, and should not be copied from a guide. The pace, focus and relevance of therapy depend on the person’s medical context, safety, access to healthcare, responsibilities and capacity. It may help to prepare for an assessment by noting what prompted the concern, what medical advice has already been received, the situations that increase worry and the impact on sleep, work, relationships or routines. This is not a request to monitor every symptom or decide that a concern is psychological. Urgent appropriate help is needed if you feel unable to stay safe, have thoughts of suicide or self harm, experience psychosis, a sudden marked change in mental state or acute physical symptoms.
