F33: Recurrent depressive disorder

Recurrent depressive disorder, falling under the ICD-10 code range of F33, is a mental health condition characterized by repeated episodes of depression. Even though individuals may have periods of healthy mood between episodes, they experience at least two episodes of depression that last for a minimum of two weeks. These depressive episodes often involve feelings of extreme sadness, low energy, loss of interest or pleasure in activities once enjoyed, difficulties with concentration, changes in appetite or weight, disturbed sleep, and thoughts of death or suicide. The exact cause is unknown but it is believed to involve a combination of genetic, biological, environmental, and psychological factors. The severity, frequency, and duration of these episodes can vary significantly between individuals, and the condition can progress and become more severe without appropriate management. Recurrent depressive disorder affects predominantly the brain, but its impact can extend to many bodily systems, manifesting in physical symptoms.
