Mood swings are often described as sudden, significant changes in someone’s mood or general state of mind. For example, when experiencing a mood swing, a person may quickly switch from feeling joyful and content to mournful and irritated – or visa versa.

People often ask me what the common causes of mood swings are. I tell them that Mood swings can be indicative of an underlying mental health condition or they could simply be triggered stressful events, certain medications, a dearth of sleep, or a lack of food or nutrition. If someone is experiencing multiple and extreme mood changes, however, they might have a mental health condition such as Cyclothymia (or cyclothymic disorder) which is when a person goes through highs and lows in mood. They might also have bipolar disorder which can cause more frequent and serious mood swings.
Therefore, if people experience serious or sustained mood swings. they should consult a doctor or other medical professional.

If someone is experiencing serious or frequent mood swings, then there are a number of different treatment options available, including medication and psychotherapy. A less stressful lifestyle might also help. As with most mental health conditions, finding the treatment that’s right for you might take a little time.
