This guide walks through what hypomania is, including its symptoms, causes, diagnosis, and treatment, so you can better understand what you're experiencing and what kind of support might help.

Hypomania happens when your mood, energy, and activity levels rise well above your normal baseline. You may feel elevated, irritable, unusually confident, or like you can't slow down.
It is a significant shift and usually lasts for several days straight. It can sometimes be hard to find awareness or want to change initially because it feels good or productive when it’s happening.
It does not include psychosis (delusions, or hearing or seeing things that aren’t really there). It is less intense than a full manic episode, which is often associated with Bipolar I disorder.
Hypomania is often part of Bipolar II disorder or cyclothymia, though people with Bipolar I can experience hypomanic episodes, too. While it's less intense than mania and usually doesn't require hospitalization, it can still meaningfully affect your daily life.
According to the key book that defines mental health disorders (the DSM-5-TR), a hypomanic episode lasts for at least 4 consecutive days. The increase in energy, activity levels, and mood are present for almost all of the time during those days. You may also notice that you need much less sleep than usual but still feel fully rested.
Everyone has changes in energy and mood, but hypomania is different. It's a noticeable, sustained shift that often gets pointed out by people around you.
If you’re only experiencing mood changes for a few hours in a day, or the levels of intensity don’t seem very high, what you are experiencing may not be a hypomanic episode. But if you’re questioning whether you’re experiencing hypomanic episodes, it’s always best to be assessed by a mental health professional.
The underlying causes of hypomania aren't fully understood, but genetics and environment both likely play a role. Hypomania and bipolar spectrum conditions tend to run in families — having a parent or sibling with bipolar disorder raises your likelihood of experiencing it yourself.
Other risk factors include emotional trauma, family conflict, or brain injury, which has been linked to a higher risk of manic and hypomanic episodes. All of these contribute to vulnerability rather than determining whether you'll experience hypomania.
If you have hypomania, triggers are experiences that can push you closer to an episode, though they won't cause hypomania in someone who doesn't already have it.
Triggers can include:
Medication reactions (e.g., antidepressants or steroids): Sometimes experiencing hypomanic episodes along with depression can be misdiagnosed as depression alone, followed by a prescription for an antidepressant (usually an SSRI). Research shows antidepressants and the supplement St. John's wort can sometimes trigger hypomanic episodes in people prone to them.
If you’re wondering if either interaction may impact you, consult with the professional who oversees your psychiatric medications. It is never recommended to make abrupt changes in your medication without speaking to your doctor or licensed prescriber first.
Ongoing stress or trauma exposure: Repeated stress or trauma, including around major life events like getting married, changing jobs, or moving can increase your likelihood of a hypomanic episode.
Disruptions in sleep patterns or circadian rhythm: Getting less sleep or having major shifts in your sleep schedule can come before an episode. Hypomania has also been linked to occurring in spring and summer, possibly because increased daylight disrupts circadian rhythms.
Menstruation and hormone events: Hormonal shifts during the menstrual cycle, particularly around the premenstrual or mid-cycle phases, may trigger mood episodes in some menstruating people.
Substance use or substance use disorder: Recreational stimulant use and cannabis use are the most commonly named substances that can trigger hypomania. High amounts of caffeine have also been associated with triggering episodes, though the evidence is not fully conclusive.
There are some key changes during a hypomanic episode. These can be related to your thoughts, emotions, or behaviors. The most common symptoms include:
A formal diagnosis comes from a clinical evaluation with a trained healthcare professional. It’s a collaborative process where they'll ask about your experiences, assess you fully, and apply their clinical judgment, with honest input from you. The diagnosis process usually includes:
When you speak with a mental health professional, they'll likely ask about your history, your family's mental health history, and details from your day-to-day experiences. They may use screening tools such as the Mood Disorder Questionnaire (MDQ), although diagnosis is based on a comprehensive clinical evaluation.
As you're assessed, they'll be looking at whether your experience matches the criteria for hypomania and related diagnoses like bipolar disorder, as laid out in the DSM-5-TR.
A professional will often ask about your medical and substance use history. If necessary, they may refer you to a medical professional to rule out any other conditions that could appear like hypomania (e.g. hyperthyroidism or Cushing’s disease).
There are different approaches that can help treat hypomania. These approaches often focus on stabilizing mood, reducing triggers, and preventing more episodes from happening. Some of the most helpful treatments include:
If symptoms intensify, begin to significantly impair your functioning, or lead to increasingly risky or unsafe behavior, it may be time to seek urgent support. Hypomania can sometimes escalate into a full manic episode, which is considered a psychiatric emergency. If you start experiencing suicidal thoughts, thoughts of hurting others, or feeling concerned about your safety, you can reach out to an emergency line such as 988.
If you or someone you know is in crisis, support is available. Call or text 988 (Suicide & Crisis Lifeline), text HOME to 741741 (Crisis Text Line), or call 911 for a mental health emergency.
Identifying and managing hypomania can feel challenging at first, and you may question whether what you're experiencing fits. An outside perspective from a therapist can help. They can assess your experience, offer feedback, and build a treatment plan suited to you.
