IgG4-RD and fatigue

IgG4-related disease (IgG4-RD) can cause a range of symptoms, including fatigue.

Because IgG4-RD affects everyone differently, fatigue can vary widely from person to person. For some, it might come and go; for others, it may feel more constant. No matter how it appears, fatigue can make everyday life harder to navigate.

Understanding what might be behind this fatigue and finding ways to work with your body’s changing energy levels can help you feel more supported in your daily routines.

Causes of IgG4-RD fatigue

The exact causes of IgG4-RD fatigue are not fully understood, but several factors may contribute to its development, including:

• Inflammation: IgG4-RD is characterized by inflammation, which is known to contribute to fatigue in the general population and in people with other inflammatory diseases.
• IgG4-RD manifestations: IgG4-RD-related dysfunction of certain organs and glands, such as the pancreas, thyroid, and kidneys, may contribute to fatigue.
• Stress: Living with a chronic condition can be stressful, and the resulting mental strain can fuel fatigue.
• Medication side effects: Some IgG4-RD treatments, such as glucocorticoids, may cause side effects that can lead to or worsen fatigue.

How IgG4-RD fatigue can affect you

Fatigue associated with IgG4-RD can affect many aspects of daily life, including work, household tasks, and relationships. At times, even simple activities may feel more difficult than usual, and focusing or staying on top of responsibilities may take extra effort.

For example, tasks at work may take longer, and meeting deadlines or concentrating on projects might feel more challenging. At home, everyday chores such as cooking, cleaning, or helping family members can leave you feeling drained.

You may also find yourself avoiding social gatherings because of low energy. Over time, this can leave you feeling more isolated or lonely.

How to manage IgG4-RD fatigue

Because the effects of IgG4-RD fatigue can be wide-ranging, it may take more than one strategy to manage it.

Working with your care team, adjusting your routine, and asking for support may help reduce fatigue’s impact on your well-being.

Communicate with your care team

The most important factor in managing IgG4-RD fatigue is having the underlying disease treated as effectively as possible. This requires regular and honest communication with your care team.

If you feel that your fatigue is not being adequately controlled, tell your doctor. They may be able to adjust your treatment plan or make other recommendations.

To prepare for appointments, consider writing down your IgG4-RD symptoms, including fatigue, and noting when they typically occur. Sharing your notes with your doctor can provide helpful information when making care decisions.

Adjust your daily routine

Making small adjustments to your daily routine can also make a meaningful difference in managing IgG4-RD fatigue.

Some ideas include:

• building regular breaks into your day and trying not to skip them
• scheduling the most demanding tasks for when you have the most energy
• pacing yourself and avoiding overexertion, especially during IgG4-RD flares, which are sudden periods of new or worsening symptoms
• being prepared to modify your plans, as IgG4-RD flares can happen unexpectedly
• going to sleep and waking up around the same time each day to support sleep quality
• trying mindfulness meditation or deep breathing to manage stress

Modify your work and home environment

Along with lifestyle changes and support from your care team, there are practical steps you can take at work and at home to help manage fatigue.

At work, ask about accommodations such as remote work, flexible schedules, or extra breaks. Prioritize tasks based on your energy levels and communicate openly with supervisors if fatigue affects your performance.

At home, accept help from family, friends, or caregivers with chores like cooking, cleaning, and errands. Set realistic expectations and pace yourself. Sharing responsibilities or rotating tasks can also reduce strain.

Support your emotional well-being

Some days are more challenging than others. If you are too tired to attend a social gathering with colleagues, friends, or family, try not to blame yourself. You may be able to join remotely or reconnect another day.

Keep in mind that maintaining social connections doesn’t always require being there in person. Picking up the phone or sending an email can help you stay in touch when leaving home feels too difficult.

You can also join an IgG4-RD support group, such as the IgG4-RD News Facebook group, for company and camaraderie. IgG4-RD peers may be able to offer additional tips for dealing with fatigue and other symptoms.

Overall, fatigue is a symptom of IgG4-RD that deserves attention and care. Through open communication with your doctor, lifestyle adjustments, and strategies to manage work and personal commitments, you can try to lessen its effects on your well-being.
