Obsessive compulsive disorder (OCD)


Obsessive Compulsive Disorder (OCD) is a mental health disorder characterized by intrusive, recurrent, and persistent thoughts, impulses, and images (obsessions) that cause significant distress and anxiety. People with OCD often engage in repetitive behaviors or rituals (compulsions) which they believe will reduce the stress created by their obsessions. Common obsessions and compulsions include fear of contamination, checking and rechecking, need for symmetry/ordering, and intrusive thoughts about harm, religious doubts, and unwanted sexual thoughts. OCD impacts a person’s ability to function in both daily and long-term activities, and treatment usually involves a combination of psychotherapy and medication.


The most common symptoms of Obsessive Compulsive Disorder (OCD) include:

  • Intrusive thoughts or images that are unwanted, distressing and difficult to manage
  • Obsessive rituals, such as compulsive hand-washing, counting, checking, or repeating certain actions
  • Anxiety and distress caused by these thoughts and rituals
  • Difficulty concentrating on other tasks due to the amount of time spent on the rituals
  • Intense fear of making mistakes or being embarrassed by the rituals
  • Difficulty controlling the thoughts and rituals, even when they cause distress and problems in other areas of life.


The exact cause of Obsessive Compulsive Disorder (OCD) is not known, however, it is believed to be a combination of biological, psychological, and environmental factors. Possible biological factors include genetics and changes in the body’s chemistry or brain structure. Psychological factors may involve how an individual interprets, processes, and responds to certain events and experiences. Environmental factors may include stressful life experiences or trauma. Additionally, some research suggests that OCD may be caused by an imbalance in serotonin, a neurotransmitter that helps control mood and behavior.

Risk factors

There are a number of risk factors that can contribute to the development of obsessive compulsive disorder (OCD).

  1. Genetics: A person’s genetic makeup may make them more or less likely to develop OCD. People with a family history of the disorder tend to be more susceptible to developing OCD.
  2. Brain Chemistry: Imbalances in certain brain chemicals, such as serotonin, may contribute to the development of OCD.
  3. Stressful Life Events: Traumatic experiences, such as a death in the family, illness, or a major life change can contribute to the onset of OCD.
  4. Age: OCD is typically diagnosed in adolescence or early adulthood.
  5. Gender: Women tend to be more likely to develop OCD than men.
  6. Personality Type: People who are perfectionists and tend to worry a lot may be more prone to developing OCD.


Obsessive compulsive disorder (OCD) is usually diagnosed by a qualified mental health professional, such as a psychiatrist, psychologist, or clinical social worker, through clinical evaluation and discussion of symptoms. A mental health professional will typically ask the patient questions about their symptoms, how long they have been experiencing them, how severe and frequent they are, and how they are impacting their life. Additionally, a mental health professional may administer tests, such as the Yale-Brown Obsessive Compulsive Scale, to further assess the severity of the disorder.


The most widely recognized type of obsessive-compulsive disorder (OCD) is characterized by a cycle of intrusive, obsessive thoughts and compulsive behaviors. This type of OCD is typically treated with a combination of cognitive behavioral therapy (CBT) and medications.

However, there are several subtypes of OCD that can manifest in different ways, and various combinations of treatments may be more successful for specific subtypes.

One type of OCD is known as Pure Obsessional OCD, or Pure O. Those with this type of OCD experience intrusive thoughts, but do not engage in compulsive behavior. Treatment for Pure O typically involves cognitive and behavioral therapy to address the intrusive thoughts as well as techniques to help manage the anxiety symptoms that accompany this type of OCD.

Another subtype of OCD is known as Scrupulosity, which involves the presence of excessive religious or moral thoughts and the fear of making a mistake or committing a sin. Treatments for Scrupulosity typically include cognitive behavioral therapy (CBT) and mindfulness-based approaches to help manage the anxiety associated with intrusive thoughts.

Hoarding is a type of OCD where a person accumulates and has difficulty discarding objects, leading to an excessive accumulation of possessions that often interfere with daily activities. Treatment for hoarding typically focuses on cognitive and behavioral therapy, as well as education and support groups to help the individual manage the anxiety associated with getting rid of objects.

Finally, Body-Focused Obsessive Compulsive Disorder (BFR-OCD) is a type of OCD where a person is preoccupied with fears related to their body and appearance. Treatment for this type of OCD typically includes cognitive-behavioral therapy, exposure and response prevention (ERP) therapy, and medications.


Treatment options for Obsessive compulsive disorder (OCD) may include medication, psychotherapy, and lifestyle modifications. Medication options may include serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, antipsychotic medications, and other medications. Psychotherapy may include cognitive behavioral therapy (CBT), exposure and response prevention (ERP), and other approaches. Lifestyle modifications may include increasing physical activity, improving sleep hygiene, reducing stress, and setting boundaries. Additionally, there are alternative treatments, such as mindfulness and self-help tips, which may be beneficial to some people with OCD.


The best way to reduce the risk of developing OCD is to practice healthy lifestyle habits such as getting enough sleep, exercising regularly, eating a balanced diet, and avoiding drug and alcohol abuse. Additionally, individuals should reduce their stress levels by engaging in stress-relieving activities such as yoga, meditation, and mindfulness. Cognitive-behavioral therapy (CBT) is also an important treatment approach for OCD and can be helpful in reducing compulsions. Psychotherapy can also help a person learn to recognize, accept, and manage their obsessive and compulsive behaviors. Finally, anti-anxiety and antidepressant medications can be prescribed to help reduce symptoms of OCD.

Gender differences?

Yes, there are gender-specific differences in the presentation and management of Obsessive compulsive disorder (OCD). Generally, women are more likely to suffer from OCD than men and are at greater risk of developing more complex and disabling cases. Studies have shown that women tend to experience more intense obsessions and compulsions, with a higher level of distress, than men. Additionally, women are more likely to report a greater variety of symptoms and longer duration of symptoms than men.

When it comes to management, studies have shown that women tend to benefit more from cognitive-behavioral therapy (CBT) than men. Women also tend to experience greater success with medication, both as monotherapy and as an adjunct to CBT. Therefore, clinicians tend to recommend a more intensive approach to treatment for women with OCD due to their greater distress and treatment responsiveness.


Nutrition plays a major role in the management of OCD, as it can affect the level of neurotransmitters in the brain that are responsible for controlling mood, anxiety, and stress. It is important to ensure that the diet contains foods that are high in omega-3 fatty acids and low in processed sugars and fats. Eating a balanced diet and avoiding foods known to worsen OCD symptoms, such as caffeine, will help to regulate serotonin levels, which in turn may help reduce symptoms of OCD. Additionally, proper hydration is essential to managing the symptoms of OCD, as dehydration can exacerbate the condition.

Physical Activity

Physical activity can be a beneficial tool to help manage symptoms of OCD. Research has shown that exercise can positively influence anxiety, which can be a major symptom of OCD. When engaging in physical activity, the brain releases chemical compounds that can boost mood and help reduce stress which can reduce the frequency and intensity of obsessive thoughts. Regular physical activity also helps increase concentration and improve mental clarity which can reduce symptoms of OCD such as rumination. As a result, physical activity can be a useful tool in helping alleviate some of the symptoms of OCD.
