Understanding Bipolar Disorder

There are three main types of bipolar disorder. A mental health professional can help you understand which type you have based on the pattern and severity of your symptoms. Bipolar I is defined by manic episodes that last at least one week or are severe enough to require hospital care. During mania, you may feel intensely energized or euphoric, and your behavior can become risky or impulsive. Some people also experience psychosis, losing touch with reality. Depressive episodes often follow, but they are not required for the diagnosis. Bipolar II involves a pattern of hypomanic episodes — a milder form of mania that lasts at least four days — along with major depressive episodes that last at least two weeks. Hypomania does not cause the same level of impairment as full mania and does not involve psychosis, but the depressive episodes can be severe and long-lasting. Bipolar II is not a milder version of bipolar I; the depressive episodes can be more frequent and harder to manage. Cyclothymia is a milder but more chronic form of bipolar disorder. People with cyclothymia experience periods of hypomanic symptoms and periods of depressive symptoms that do not meet the full criteria for hypomanic or major depressive episodes. These symptoms must be present for at least two years in adults, with symptom-free periods lasting no longer than two months at a time.

Bipolar disorder causes extreme shifts in mood, energy, and activity levels. These shifts are called mood episodes and can last for days or weeks at a time. Between episodes, many people have periods of stable mood. Manic episode symptoms:

• Feeling extremely happy, excited, or euphoric
• Feeling unusually irritable or agitated
• Having racing thoughts and talking very fast
• Needing very little sleep without feeling tired
• Feeling overly confident or powerful (grandiose beliefs)
• Acting impulsively — spending sprees, risky decisions, or reckless behavior
• Increased sex drive
• Feeling jumpy or restless
• In severe cases, losing touch with reality (psychosis)

Hypomanic episode symptoms are similar but less intense. You may feel very productive, creative, or energetic, and others may notice a change in your behavior. Hypomania does not cause major problems at work or in relationships and does not involve psychosis. Depressive episode symptoms:

• Deep sadness, hopelessness, or emptiness
• Loss of interest in activities you once enjoyed
• Low energy and constant fatigue
• Trouble concentrating, remembering, or making decisions
• Changes in appetite or weight
• Sleeping too little or too much
• Feeling worthless or guilty
• Thoughts of death or suicide

Mixed episodes: Some people experience symptoms of mania and depression at the same time — for example, feeling full of energy while also feeling deeply sad and hopeless. This combination can be especially distressing and requires prompt attention. If you or someone you know is having thoughts of suicide, call or text 988 to reach the Suicide and Crisis Lifeline. It is free, confidential, and available 24/7.

The exact cause of bipolar disorder is not fully understood, but research suggests it results from a combination of genetic, biological, and environmental factors. Genetics plays a significant role. Bipolar disorder tends to run in families. If you have a parent or sibling with bipolar disorder, your risk of developing it is higher. However, most people with a family history of the condition do not develop it, and many people with bipolar disorder have no known family history. Brain chemistry and structure also matter. The levels of neurotransmitters — chemicals that carry signals in the brain — can be different in people with bipolar disorder. Certain areas of the brain may also function differently, particularly those involved in regulating mood, energy, and impulse control. Environmental factors can trigger the first episode or contribute to future episodes. These include:

• High levels of stress, such as the loss of a loved one, financial problems, or relationship difficulties
• Traumatic experiences, including emotional, physical, or sexual abuse during childhood
• Major life changes, such as starting a new job, moving, or giving birth
• Disrupted sleep patterns
• Substance use, including alcohol, cannabis, and cocaine
• Certain medications that can trigger mood changes

It is important to understand that bipolar disorder is not caused by anything you did or did not do. It is a medical condition with strong biological roots, just like diabetes or heart disease.

Diagnosing bipolar disorder can take time because its symptoms overlap with other mental health conditions such as depression, anxiety disorders, and ADHD. There is no single blood test or brain scan that can confirm the diagnosis. The diagnostic process typically involves:

• A physical exam and lab tests to rule out other medical conditions that could be causing your symptoms
• A detailed discussion of your symptoms, personal medical history, and family mental health history
• A psychiatric evaluation by a mental health professional, such as a psychiatrist
• Keeping a mood diary to track your emotions, energy levels, sleep patterns, and triggers over time
• Sometimes, conversations with family members who can provide additional insight into your mood changes

Your doctor will use the criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to determine whether your symptoms match one of the bipolar disorder types. They will consider how severe your symptoms are, how long they last, and how often they occur. Getting an accurate diagnosis can take weeks or months, especially if your symptoms are mild or if you have only experienced depressive episodes (which can look like regular depression). This is why it is important to work with a specialist who has experience diagnosing and treating bipolar disorder.

While there is no guaranteed way to prevent bipolar disorder itself, there are effective strategies for reducing the frequency and severity of mood episodes once you have been diagnosed. Stick with your treatment plan. Taking your medications as prescribed — even when you feel well — is the single most important step in preventing relapse. Do not stop or change your medication without talking to your doctor first. Keep a regular routine. Going to bed, waking up, eating meals, and exercising at roughly the same time each day helps stabilize your body’s internal clock, which can reduce the risk of mood episodes. Even small disruptions to your sleep schedule can trigger symptoms for some people. Learn to recognize early warning signs. Pay attention to changes in your sleep, energy, mood, or behavior that may signal an episode is coming. Catching these signs early allows you to reach out to your doctor and adjust your treatment before symptoms become severe. Avoid drugs and alcohol. Substance use can trigger mood episodes, interfere with medications, and make symptoms worse. If you need help cutting down or quitting, talk to your doctor or a support group. Manage stress. Chronic stress is a known trigger for mood episodes. Finding healthy ways to cope — such as exercise, meditation, mindfulness, or talking to a therapist — can make a meaningful difference. Build a support system. Having people around you who understand your condition can help you stay on track with treatment and provide support when you need it. This might include family, friends, a therapist, or a support group for people with bipolar disorder. Get regular exercise and eat a balanced diet. Physical activity can help stabilize mood and improve sleep. A nutritious diet supports overall brain health and helps you maintain a stable routine.

Bipolar disorder is a lifelong condition, but with proper treatment and self-management, most people can achieve long periods of stable mood and lead full, productive lives. The key is consistent treatment and attention to your mental health. Medication is the foundation of treatment for most people, and finding the right combination of medications can take time. Once you find a regimen that works, staying on it is essential — even during periods when you feel well. Sudden discontinuation of medications is one of the most common causes of relapse. Therapy is also important. Cognitive behavioral therapy, interpersonal and social rhythm therapy, and psychoeducation can help you understand your condition, recognize early warning signs, and develop effective coping strategies. Several factors influence your long-term outlook:

• Early diagnosis and treatment lead to better outcomes
• Consistent use of medication reduces the risk of relapse
• A strong support network helps you stay on track
• Healthy lifestyle habits — regular sleep, exercise, and stress management — can significantly reduce symptom severity
• Avoiding alcohol and recreational drugs protects your stability

Without treatment, bipolar disorder can have serious consequences. Mood episodes can become more frequent and severe over time, which is sometimes called kindling. Untreated bipolar disorder can lead to relationship problems, financial difficulties, job loss, substance abuse, and an increased risk of suicide. With the right care and support, however, the vast majority of people with bipolar disorder can manage their symptoms effectively, maintain meaningful relationships, work productively, and enjoy a good quality of life.

Treatment for bipolar disorder typically involves a combination of medication and psychotherapy. A psychiatrist will work with you to find the right treatment plan based on your specific symptoms and needs. Medications are usually the first line of treatment:

• Mood stabilizers such as lithium help prevent both manic and depressive episodes. Lithium is one of the most studied and effective treatments for bipolar disorder.
• Anticonvulsant medications, such as valproate and lamotrigine, can also help stabilize mood and are sometimes used when lithium is not effective or well tolerated.
• Antipsychotic medications such as olanzapine, quetiapine, and aripiprazole are often used during manic episodes or for maintenance treatment.
• Antidepressants may be prescribed for depressive episodes but are almost always combined with a mood stabilizer to avoid triggering a switch into mania.

Psychotherapy plays a vital role in managing bipolar disorder:

• Cognitive behavioral therapy (CBT) helps you identify unhelpful thought patterns and develop practical coping skills.
• Interpersonal and social rhythm therapy focuses on stabilizing your daily routines and improving your relationships.
• Psychoeducation helps you learn about your condition and recognize early signs of mood shifts.
• Family therapy involves your loved ones so they can better understand your condition and support you.

Other treatment options may be considered in specific situations:

• Electroconvulsive therapy (ECT) can be highly effective for severe depression or mania that has not responded to other treatments.
• Repetitive transcranial magnetic stimulation (rTMS) uses magnetic pulses to stimulate areas of the brain involved in mood regulation.
• Day treatment programs or intensive outpatient programs provide structured support without requiring hospitalization.
• Hospitalization may be necessary if you are at risk of harming yourself or others during a severe episode.

Never stop or change your medications without your doctor’s guidance. Abruptly stopping can trigger a severe mood episode. Always work with your healthcare team to adjust your treatment as needed.

What you eat can play a supporting role in managing bipolar disorder. While diet cannot replace medication or therapy, a balanced, nutrient-rich diet supports brain health and can help stabilize mood. Eat regular meals. Skipping meals or going for long periods without food can affect your blood sugar levels and energy, which may influence your mood. Eating at consistent times also supports a healthy daily routine, which is important for mood stability. Focus on whole foods:

• Fruits and vegetables provide vitamins, minerals, and antioxidants that support brain function
• Whole grains such as oats, brown rice, and quinoa provide steady energy and fiber
• Lean proteins from fish, chicken, beans, and legumes help produce the neurotransmitters that regulate mood
• Healthy fats from olive oil, avocados, nuts, seeds, and fatty fish support brain cell structure and communication

Omega-3 fatty acids have been studied for their potential mood-stabilizing effects. Found in salmon, mackerel, sardines, flaxseeds, chia seeds, and walnuts, omega-3s may help reduce inflammation in the brain and support the effectiveness of mood stabilizers. Some studies suggest that omega-3 supplements may offer additional benefits when used alongside medication. What to limit or avoid:

• Caffeine and stimulants can interfere with sleep and trigger manic symptoms in some people
• Alcohol can destabilize mood, interfere with medications, and disrupt sleep
• High-sugar and highly processed foods can cause energy crashes that may worsen depressive symptoms
• Very large meals close to bedtime can disrupt sleep

Stay hydrated. Dehydration can affect concentration, energy levels, and mood. Aim for adequate water intake throughout the day. Talk to your doctor about supplements. Some supplements, such as SAMe and St. John’s wort, can interact with bipolar medications and may trigger mania. Always discuss any supplement with your healthcare provider before taking it. Maintaining a healthy weight through balanced nutrition is also beneficial, as obesity is associated with more severe bipolar symptoms and a poorer response to treatment.

Bipolar disorder is a mental health condition characterized by extreme shifts in mood, energy, and functioning. It affects approximately 2.8 percent of U.S. adults and typically first appears between the ages of 15 and 24. There are three main types: bipolar I, defined by full manic episodes; bipolar II, defined by hypomanic episodes paired with major depression; and cyclothymia, a chronic but milder form. The exact cause involves a combination of genetic, biological, and environmental factors, with family history being a significant risk factor. Diagnosis can take time because symptoms overlap with other conditions and requires a thorough evaluation by a mental health professional. Treatment centers on medication — particularly mood stabilizers like lithium — combined with psychotherapy such as cognitive behavioral therapy and interpersonal and social rhythm therapy. Lifestyle measures including a regular routine, adequate sleep, exercise, stress management, and a balanced diet all support treatment and help prevent mood episodes. With consistent treatment and a strong support system, most people with bipolar disorder can achieve long periods of stability and lead fulfilling lives.
