Mood swings are a normal part of being human. We all have good days and bad days, but bipolar disorder is something else entirely. It brings episodes of intense mood between (mania or hypomania) and deep depression. It is a condition that can affect the person’s thinking, behaviour, energy, relationships, work, and even self-care.
These aren’t just “bad moods.” These are clinical patterns that can often last days, weeks, or longer. The encouraging part…..with a proper diagnosis and evidence-based care, most people with bipolar disorder reclaim their lives. Often, the first people to notice something is off are friends and family. Especially during hypomanic stages where changes in sleep patterns, speech, or energy levels can become apparent.
The Main Types of Bipolar Disorder
Bipolar disorder breaks down into three main types:
- Bipolar I Disorder: Characterised by at least one full manic episode — a period of elevated, expansive, or irritable mood with high energy that goes on for 7 days or longer (or any duration if hospitalisation is needed). Mania often comes with psychosis, and depressive episodes usually follow.
- Bipolar II Disorder: This type involves hypomanic episodes (milder highs that lasts for at least 4 days) and at least one major depressive episode. However, people with Bipolar II do not experience full mania. This form is frequently seen in clinical settings because people often seek help during the more distressing depressive phases.
- Cyclothymic Disorder: A chronic, milder pattern of fluctuating hypomanic and depressive symptoms that don’t meet full criteria for mania or major depression. Symptoms persist for at least 2 years (1 year in youth) with few normal periods.
Research shows, including the World Mental Health Survey Initiative across multiple countries, estimates lifetime prevalence of the bipolar spectrum around 2.4%, with Bipolar I at ~0.6% and Bipolar II at ~0.4%. The World Health Organisation says somewhere around 37 to 46 million people worldwide are living with some form of bipolar disorder.
Although all forms sit within the same diagnostic spectrum, the way symptoms appear can vary widely from person to person. Some people go long stretches without an episode; others face these shifts more often, even several times a year.
A Closer Look at Bipolar II: More Common Than You Might Think
In my consulting room, Bipolar II is one of the most frequently encountered presentations. They often seek help for depression. They may not realise that their history includes periods of hypomania. While global prevalence figures show Bipolar I and II as relatively similar, Bipolar II often comes to clinical attention because of prominent, prolonged depressive episodes.
Hypomania can feel deceptively positive: boosted energy, sharp creativity,more confidence, less need for sleep, and a feeling of being nearly invincible. That’s the upside. But it can also bring irritability, impulsivity, and later exhaustion.
Depressive episodes tend to dominate, bringing persistent sadness, fatigue, loss of interest, difficulty concentratings, withdrawal, hopelessness, and elevated suicide risk. Studies show depression drives much of the morbidity in Bipolar II.
One of the challenges of Bipolar II is that it can be misdiagnosed. Studies show that 40–70% of people with bipolar disorder are initially diagnosed with unipolar depression, with delays of 5–10 years or more common. With Bipolar II, hypomania is often subtle, dismissed as ‘just being productive’ or “high energy.” Antidepressants alone can sometimes worsen the course by triggering hypomania.
How to Recognise the Signs
During hypomania (Bipolar II): Increased talkativeness, racing thoughts, goal-directed activity, distractibility, impulsivity (e.g., spending, decisions), and reduced sleep need. These periods can appear less disruptive on the surface, but they often lead to exhaustion or emotional crashes afterwards.
During depression: The depressive phases, however, tend to dominate the overall experience, bringing persistent low mood, reduced motivation, withdrawal from social contact, and feelings of worthlessness.
Because hypomania does not always cause obvious impairment, it can be overlooked or mistaken for periods of high functioning. This is one reason Bipolar II is sometimes misdiagnosed as depression in its early stages.
Early recognition by the person, family, or friends can make a big difference. Tracking mood, sleep, and energy patterns is a practical tool I often recommend.
Living Well With Bipolar Disorder
Bipolar disorder is a chronic condition, but it can be managed. Those who do best take an active, empowered role in their care — knowing what triggers a mood shift, recognising early warning signs, and having a plan in place before things start to turn.
Research shows that combined medication and psychotherapy yields better outcomes than medication alone.
Final Thoughts from My Practice
What should everyone know about bipolar disorder? It’s not a character flaw or weakness. It’s a medical condition rooted in brain chemistry, genetics, and environment. With the right treatment and support, people with bipolar live full and meaningful lives. Many highly creative and successful individuals have thrived while managing it.
If you recognise these patterns in yourself or someone you love, reach out for help. Getting the right diagnosis and tailored treatment can change everything. In my work, I’ve witnessed countless clients move from confusion and exhaustion to clarity, stability, and renewed purpose.
You’re not alone — and you don’t have to face this in the dark.
