Overview

Hypomania: Please look at these three things first

  • Hypomania is a state where, unlike usual, your mood and activity levels become elated or irritable, and you continue to feel energetic even with reduced sleep.
  • Unlike the temporary vitality felt after a good day or a restless night, check whether your speech, thoughts, spending, appointments, and judgment are distinctly different from usual.
  • Depression If these changes occur during treatment, do not stop your medication on your own and promptly notify your psychiatry treatment team.

Meaning and Distinctions

What is hypomania?

In hypomania, you may feel more elated or irritable than usual, your activities, speech, and thoughts may speed up, and you may feel less fatigue even if you sleep less. While you may feel that your productivity has improved, those around you may notice changes in your spending, appointments, judgment, and daily rhythm. Hypomania is a state where mood and activity become elated or irritable, and changes such as not feeling tired despite reduced sleep persist for a certain period.

Easily confused terms
Unlike the temporary vitality felt after a good day or a restless night, check whether your speech, spending, judgment, and activities are distinctly different from usual.
Why this is checked during medical evaluation
First, confirm the possibility of bipolar disorder and the influence of medication at a psychiatry clinic, then continue current treatment. When considering Korean herbal medicine treatment together, the fact that sleep has decreased is not viewed simply as insomnia; instead, the treatment scope is determined by examining how the increase in activity, speech, spending, and impulsivity changed during the same period as throbbing, digestion, body heat, and tension.
What to write down for your visit
Record by date how many hours of sleep were reduced compared to usual, for how long, and how your speech, activity, spending, appointments, and impulsivity changed. Please also provide information on changes in prescribed medications such as antidepressants, steroids, or stimulants, as well as caffeine and alcohol intake. If you remain elated despite almost no sleep, or if you experience dangerous behavior, delusions, hallucinations, or thoughts of self-harm or harming others, seek a psychiatry evaluation or emergency evaluation before Korean herbal medicine treatment.

Connecting hypomania to my symptoms

Check both your own sense of vitality and the changes noticed by those around you

Even if you feel that things are going well and your confidence has increased, family or colleagues may notice that your speech has become faster and that your appointments, spending, driving, or interpersonal conflicts have changed. Record your sleep duration, activity level, spending, and important decisions for a few days and compare them with your usual self.

Do not only mention depressive periods; you must also report elated periods

When receiving medical evaluation, you must mention not only the periods of depression and lethargy but also the periods when you were not tired despite little sleep and when your activity increased significantly. Since thyroid diseases and medication effects can cause similar changes, overall medication history and test results are reviewed. If your judgment of reality becomes blurred or you have thoughts of dangerous behavior or self-harm, seek immediate psychiatric emergency help.

Frequently Asked Questions

Common questions when looking into hypomania

Is it hypomania if I feel good and things are going well?

Judgment is not made based on that fact alone. We evaluate whether the need for sleep has decreased, speech, thoughts, and activities have sped up, spending, judgment, and relationships have distinctly changed from usual, and whether this has persisted for a certain period.

If I sleep less and feel elated after taking antidepressants, should I stop the medication?

Do not discontinue the medication arbitrarily; immediately notify your prescribing medical team of the date the changes began and the changes in sleep, activity, and impulsivity. The medication must be adjusted safely after evaluating your current state.

Key Points

  • Meaning of hypomania: In hypomania, mood may become more elevated or irritable than usual, and activity, speech, and thoughts may accelerate, with less fatigue felt despite reduced sleep. While the individual may feel their productivity has improved, those around them may notice changes in spending, appointments, judgment, and daily rhythms.
  • Difference from similar states: Unlike a simply good day or temporary energy after a poor night's sleep, we look for distinct changes from the usual patterns in speech, spending, judgment, and activity.
  • Reason for confirmation during evaluation: The possibility of bipolar disorder and the effects of medication are first confirmed by a psychiatry department before continuing current treatment. When reviewing Korean herbal medicine treatment, the fact that sleep has decreased is not viewed simply as insomnia; instead, we determine the scope of treatment by examining how increases in activity, speech, spending, and impulsivity coincided with changes in pulsating sensations, digestion, body heat, and tension.
