Bipolar disorder and sex drive: How different mood phases affect desire and intimacy
Published Mar 30, 2026 • By Candice Salomé
Bipolar disorder is often associated with major shifts in mood, alternating between depressive episodes and manic or hypomanic phases. But these emotional changes do not affect only mood or energy levels; they can also have a deep impact on intimate and sexual life.
Some people living with bipolar disorder describe an increase in libido during manic phases, while others experience a significant drop in desire during depressive episodes. On top of this, treatment side effects and the impact on the relationship itself can also play a role.
These changes can sometimes be hard to understand, both for the person living with the condition and for their partner. Yet a better understanding of the links between bipolar disorder, desire, and sexuality can help support open communication and protect the balance of the relationship.
In this article, we’ll explore how bipolar disorder can affect intimacy, the mechanisms involved, and why communication matters so much within the relationship.
Understanding bipolar disorder and emotional fluctuations
Bipolar disorder is a mood disorder characterized by significant shifts between depressive episodes and periods of elevated mood known as manic or hypomanic episodes. These changes can affect many areas of daily life, including intimate and sexual life.
The emotional and energy fluctuations associated with bipolar disorder can lead to noticeable changes in sexual desire. Some people may experience a marked increase in libido during manic phases, while desire can drop significantly during depressive episodes.
Understanding these variations is key to better recognizing how bipolar disorder affects sexuality and to maintaining balance within a relationship.
Manic phases: When sexual desire increases
Hypersexuality and Impulsivity
During a manic or hypomanic episode, some people living with bipolar disorder may experience a significant increase in sexual desire. This phenomenon is sometimes referred to as hypersexuality.
Higher energy levels, a reduced need for sleep, and increased impulsivity can lead to more frequent or unusual sexual behaviors. Some people may also be more likely to take risks or engage in impulsive sexual activity.
These experiences are not the same for everyone, but they can sometimes lead to personal or relationship difficulties.
Possible consequences
Hypersexuality can have different consequences, particularly within relationships. Partners may feel unsettled by sudden changes in behavior or by an intensity that feels unfamiliar.
In some cases, impulsive behaviors may also lead to regret or relationship difficulties once the manic episode has passed.
Depressive phases: A drop in desire and energy
Reduced libido
In contrast to manic phases, depressive episodes are often associated with a marked decrease in sexual desire. Fatigue, persistent low mood, and loss of interest in previously enjoyable activities can all affect intimate life.
Some people may find it difficult to feel pleasure or emotional closeness with their partner during these periods.
Impact on the relationship
A reduced libido can sometimes be misunderstood by a partner. Without context, it may be interpreted as a loss of interest in the relationship itself.
Recognizing that these changes are linked to the condition can help couples navigate these periods with more understanding.
The impact of treatment on sexuality
Treatments used to manage bipolar disorder can also influence sexual health.
Some mood stabilizers and other psychotropic medications may cause sexual side effects, such as reduced desire or difficulties with arousal.
These effects do not affect everyone and can vary depending on the medication and the individual. If they become bothersome, it is important to discuss them with a healthcare professional, who may be able to adjust the treatment if needed.
The importance of communication in the relationship
Understanding fluctuations
Communication plays a key role in managing intimacy when one partner is living with bipolar disorder.
Openly discussing mood changes and their impact on desire can help both partners better understand what is happening and avoid misunderstandings.
Finding balance
Each couple gradually develops their own ways of maintaining balance despite the changes linked to the condition.
This may involve recognizing early signs of an episode, adjusting expectations, or seeking therapeutic support when needed.
Towards a more holistic approach to sexual health
Sexuality is an important part of overall well-being and quality of life. In the context of bipolar disorder, it can be influenced by emotional fluctuations, treatments, and relationship dynamics.
A holistic approach to managing bipolar disorder, one that takes into account mental health, relationships, and intimate life, can help both individuals and their partners live better with the condition.
Acknowledging that these challenges can exist is often the first step toward opening up conversations and finding solutions that feel right for each situation.
