Hypomania: Signs, Causes and When to Get Help
Hypomania is a milder form of mania with elevated mood, energy and less need for sleep for at least 4 days. Learn the signs, causes, link to bipolar II and treatment.
Hypomania is a period of at least four consecutive days of abnormally elevated, expansive or irritable mood with increased energy, plus symptoms such as decreased need for sleep, talkativeness, racing thoughts, distractibility, increased activity and risky decisions. Unlike mania, it does not cause severe impairment or psychosis. Hypomania is the defining feature of bipolar II disorder and cyclothymia.
Key takeaways
- Hypomania lasts at least 4 days and is noticeable to others.
- It does not cause psychosis or require hospitalization.
- It often feels good, so people rarely seek help during it.
- Hypomania plus depression suggests bipolar II disorder.
- Antidepressants alone can trigger hypomania in people with bipolar disorder.
For a few days you feel amazing: brimming with energy, ideas and confidence, sleeping four hours and still feeling fresh, talking faster and taking on new projects. Friends notice you are “different.” Then it fades, sometimes into a crash of depression. That pattern may be hypomania.
This guide explains what hypomania is, the signs, how it differs from mania and happiness, what causes it and how it is treated. See also mania and bipolar disorder treatment.
What is hypomania?
Hypomania is a distinct period of elevated or irritable mood and increased energy lasting at least four days, present most of the day, nearly every day. It must be a clear change from your usual self and noticeable to others, but not severe enough to cause marked impairment, require hospitalization or include psychosis. If any of these occur, it is considered mania.

Why hypomania matters
Hypomania itself may feel productive, but it often precedes depression, can lead to costly decisions, and signals bipolar disorder. Recognizing it is critical because treating bipolar depression with antidepressants alone can worsen mood cycling. See signs of bipolar disorder in women.
Treatment
Treatment focuses on mood stabilization with medications such as lithium, lamotrigine or certain atypical antipsychotics, along with psychoeducation, regular sleep and social rhythm therapy. Tracking mood and sleep helps catch early signs.
