Bipolar disorder can run in families, but having a relative with the condition does not mean you will definitely develop it yourself. 

Is bipolar disorder hereditary? 

Some research suggests that bipolar disorder and other mental health conditions can be more common in families. If you have a family member with bipolar disorder, your risk may be higher than average. However, most people with a family history do not go on to develop the condition themselves. 

Why does bipolar disorder run in families? 

The reasons are not fully understood. It is likely to be a mix of genetic and environmental factors. This means that while genes may play a part, your experiences and environment matter too. 

What if bipolar disorder is in my family? 

Having a relative with bipolar disorder is just one possible risk factor. There are many things you can do to look after your mental health, even if there is a family history. Looking after your wellbeing, seeking support early, and staying informed can all make a difference.
