I experience massive fatigue with bipolar disorder. True, there are likely other components to my fatigue, but I know bipolar disorder is a driving factor. The fatigue is so bad that I think it’s one of the worst parts of bipolar disorder or any chronic illness. Fatigue affects my life on a daily basis like no other symptom of bipolar disorder and worse yet, there are pretty much no cognitive tools I can use to cope with it. Read on to learn about bipolar disorder and fatigue, why it’s so hard to best and the treatments for fatigue in bipolar.

What Is Fatigue?

Fatigue feels like extreme weariness. Fatigue feels like every cell has no energy, every cell is exhausted. Fatigue feels like a ball and chain is attached to your body every six inches and you’re being forced to drag that iron around every day and you don’t have the strength or stamina to do it.

According to one study (referenced at the end):

Patients describe fatigue as diminishing vitality, work and activities because of muscular weakness, and/or impairment in their cognitive functioning.

But fatigue is not the same as tiredness. I didn’t truly understand the difference for years, but now I do. Watch this video for more on how fatigue and tiredness aren’t the same thing.

What Is Fatigue in Bipolar Disorder?

Fatigue (or loss of energy) is a core diagnostic symptom of depression so it makes sense that people in a major depressive episode as part of bipolar disorder would be experiencing it. However, I have found that fatigue is considerably stickier than that. Fatigue seems to happen in bipolar disorder even when the depression is not as prominent. Research does bear this out. People with major depression experience fatigue even when successfully treated with antidepressants, even to what is considered remission.

There doesn’t seem to be the same kind of data on fatigue in bipolar disorder; however, I suspect we can generalize that if people with major depression experience fatigue even in remission, then those with bipolar disorder likely experience fatigue even when not in a depression.

The Problem with Fatigue in Bipolar Disorder

To someone who has not experienced fatigue, it might sound like just drinking extra coffee or sleeping more would fix the issue. After all, if you’re tired (not the same thing [see video above], but more widely understood), that can work. But fatigue just isn’t like that. Fatigue doesn’t respond to the same things that being tired does. Fatigue is constant. For those who experience it, fatigue is something we have to battle every second of every day. I wake up fatigued and I go to bed fatigued (although the mornings are better for me). For me, with bipolar disorder and fatigue, it feels like I’m exhausted all the time but I’m able to fight it — until I can’t. I fight, and fight, and fight and then I just seem to crumple into a ball, unable to move an inch. It’s then that I have to lie down, and lie down, and lie down. It feels like half of my days are spent desperately fighting the fatigue and the other half are spent lying down, giving into it. In other words, 100 percent of my days are spent being controlled by fatigue.

And I’m not the only one. Not only might people with bipolar experience fatigue but so might people with major depression, anemia, thyroid dysfunction, or cancer, among many other illnesses.

Treating Fatigue in Bipolar Disorder

Believe it or not, there may be things you can do to help fatigue in bipolar disorder or another disorder. While there isn’t a lot of empirical support for it, these antidepressants are thought to help with fatigue because of their specific mechanisms:

  • Venlafaxine (Effexor)
  • Bupropion (Welburtin)
  • Fluoxetine (Prozac)
  • Sertraline (Zoloft)

Of course, if you have bipolar disorder, antidepressants may not be an option for you as antidepressants can destabilize a person with bipolar disorder. That said, some people are able to take an antidepressant if it is prescribed alongside one or more mood-stabilizing drugs. Your doctor can tell you more about this risk.

Another option to fight fatigue is modafinil (Provigil). Modafinil is what is known as a “wakefulness-promoting agent” that is typically prescribed for those with narcolepsy (typically, excessive sleepiness during the day). Modafinil is also known to help with depressive symptoms — possibly because it improves fatigue and this helps with other depression symptoms. (I don’t know of any information about modafinil destabilizing a person with bipolar disorder, but your doctor should be able to evaluate your risk.)

Amphetamines (Adzenys, Adderall) and methylphenidate (Ritalin) (these drugs are often prescribed for attention-deficit/hyperactivity disorder [ADHD]), can also reduce fatigue although these drugs tend to work on fatigue more slowly and less frequently. (Again, your doctor should be able to evaluate the risk of adding this type of medication to your existing medication(s).)

Finally, new research suggests that ketamine can also reduce fatigue in bipolar disorder. One study using ketamine infusions in those with treatment-resistant bipolar disorder found that:

. . . ketamine significantly lowered fatigue scores compared to placebo from 40 minutes post-treatment to Day 14 with the exception of Day 7. The largest difference in anti-fatigue effects between placebo and ketamine was at day 2 . . . The effect remained significant after controlling for changes in non-fatigue depressive symptoms.

In other words, ketamine reduced fatigue in bipolar disorder even when other depression symptoms were not similarly improved, indicating that ketamine (which alters glutamate) may specifically target the symptom of fatigue for improvement. Unfortunately, ketamine can be difficult to obtain and is out-of-reach for many. (Note that this study was on ketamine IV infusions and not the more available intranasal form of ketamine.)

Finally, while I haven’t seen it mentioned specifically, I suspect that exercise can help with fatigue as well. Of course, some people will be so fatigued that this simply isn’t an option for them. If this is you, I understand completely.

Bipolar Disorder and Fatigue

So that’s the story of fatigue and bipolar disorder. Unfortunately, I haven’t found anything that truly helps my fatigue dramatically (although I haven’t tried ketamine). That said, maybe one of the above will be more useful for you.

If you’ve found something that helps with fatigue, please let us know in the comments.
