What is mood swings?
It's normal for your mood to change through the day. Mood swings stand out because the shifts are bigger, faster, or harder to explain. They can strain relationships. They can also make you feel unpredictable, even to yourself, which is its own kind of tiring.
Key things to know
Common causes include stress, poor sleep, hunger, alcohol, and hormone changes like PMDD. Mood swings are also part of conditions like depression, ADHD, bipolar disorder, and borderline personality disorder. In bipolar disorder, episodes last days or weeks, not hours. The DSM-5 sets at least 4 days for hypomania and 7 for mania.
- Some mood change is normal. Big, sudden swings are worth noticing.
- Sleep, stress, hunger, alcohol, and hormones are common triggers.
- Bipolar episodes last days or weeks, not minutes.
- A mood log over a few weeks helps you and a doctor see patterns.
- Severe swings or risky behaviour need a professional assessment.
What helps
It helps to track your mood, sleep, and triggers for a few weeks. Patterns are easier to see once they're written down. Regular sleep, regular meals, and less alcohol help a lot of people. If the swings are severe, hurt your work or relationships, or come with risky behaviour, don't wait. See a psychiatrist.
