What is Bipolar II Disorder?

Bipolar II Disorder is a mental health condition characterized by periods of depression and hypomania, which is a less severe form of mania. Unlike Bipolar I Disorder, which involves full-blown manic episodes, Bipolar II Disorder features hypomanic episodes that are less intense but can still significantly impact an individual’s life. Understanding Bipolar II Disorder, including its causes, symptoms, and treatments, is crucial for effective management and improving the quality of life for those affected.

What is Bipolar II Disorder?

Bipolar II Disorder is one of the two main types of bipolar disorder. It is defined by a pattern of depressive episodes and hypomanic episodes, but not the full-blown manic episodes typical of Bipolar I Disorder. Hypomania is characterized by elevated or irritable mood, increased activity or energy levels, and changes in behavior that are noticeable by others but not severe enough to cause significant impairment in social or occupational functioning or to necessitate hospitalization [1].

Causes and Risk Factors

The exact cause of Bipolar II Disorder is not fully understood, but it is believed to result from a combination of genetic, biological, and environmental factors.

Genetic Factors

Genetics play a significant role in the development of type II bipolar disease. Studies have shown that individuals with a family history of bipolar disorder are at a higher risk of developing the condition. Researchers believe that multiple genes may contribute to the susceptibility to bipolar disorder, although no single gene has been identified as the definitive cause [2].

Biological Factors

Biological factors, including chemical imbalances in the brain, are also thought to play a key role in Bipolar II Disorder. Neurotransmitters such as serotonin, dopamine, and norepinephrine, which are involved in regulating mood, may be imbalanced in individuals with bipolar disorder. This imbalance can lead to the mood swings characteristic of the disorder [3].

Environmental Factors

Environmental factors, including significant life changes, stress, and traumatic experiences, can trigger or exacerbate symptoms of type 2 bipolar disease. Stressful life events such as the loss of a loved one, job loss, or relationship issues can act as triggers for mood episodes in individuals predisposed to the condition [4].

Physical Factors

Certain physical health conditions, such as thyroid imbalances and neurological disorders, can also contribute to the onset and progression of Bipolar II Disorder. These conditions can affect brain function and lead to mood dysregulation [5].

Bipolar II Signs & Symptoms

The symptoms of Bipolar II Disorder include both depressive and hypomanic episodes, each with distinct characteristics.

Depressive Episodes

  • Persistent feelings of sadness or emptiness
  • Loss of interest or pleasure in most activities
  • Significant weight loss or gain
  • Insomnia or excessive sleeping
  • Fatigue or loss of energy
  • Feelings of worthlessness or excessive guilt
  • Difficulty concentrating or making decisions
  • Recurrent thoughts of death or suicide [1]

Hypomanic Episodes

  • Elevated or irritable mood
  • Increased activity or energy levels
  • Decreased need for sleep
  • Unusual talkativeness
  • Racing thoughts or ideas
  • Increased distractibility
  • Engagement in risky behaviors (e.g., excessive spending, reckless driving)
  • Inflated self-esteem or grandiosity [3]


Diagnosing Bipolar II Disorder involves a thorough clinical evaluation, including a detailed medical and psychiatric history, physical examination, and standardized assessment tools. Mental health professionals use the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria to diagnose Bipolar II Disorder. Key diagnostic criteria include the presence of at least one hypomanic episode and one major depressive episode, without any history of full-blown manic episodes [2].

Bipolar II Treatment

While medication is a common component of treatment for Bipolar II Disorder, this article will focus on non-pharmacological interventions and the importance of professional help.The best therapy for bipolar 2 disorder can only be prescribed by a qualified doctor.


Psychotherapy, also known as talk therapy, is an essential part of treatment for type 2 bipolar disorder. Cognitive-behavioral therapy (CBT) is particularly effective in helping individuals recognize and change negative thought patterns and behaviors. Interpersonal and social rhythm therapy (IPSRT) can help stabilize daily rhythms and improve interpersonal relationships, which are often disrupted in bipolar disorder [3].

Lifestyle Modifications

Adopting a healthy lifestyle can significantly impact the management of Bipolar II Disorder. Regular exercise, a balanced diet, adequate sleep, and stress management techniques such as mindfulness and relaxation exercises can help stabilize mood and reduce the frequency and severity of episodes [4].

Support Systems

Building a strong support system is crucial for individuals with Bipolar II Disorder. This can include family, friends, support groups, and mental health professionals. Support systems provide emotional support, help individuals adhere to treatment plans, and offer practical assistance during challenging times [3].

Professional Help

It is essential to seek professional help for the diagnosis and treatment of Bipolar II Disorder. Mental health professionals can provide comprehensive care, including psychotherapy, lifestyle guidance, and medication management when necessary. Regular follow-up appointments are important to monitor progress and make adjustments to the treatment plan as needed [2]. At URP Behavioral Health, you will receive the best professional care.
