Understanding Fibromyalgia Flare Ups

Fibromyalgia flare ups are periods where symptoms worsen in intensity or frequency. During these episodes, daily routines and overall comfort can be disrupted by various physical and emotional challenges.
What Are Fibromyalgia Flare Ups
A fibromyalgia flare up is a temporary increase in the severity of symptoms. These episodes can last from a few days to several weeks. Triggers for flare ups often include physical or emotional stress, changes in weather, hormonal shifts, and poor sleep.
People report that symptoms may come and go unpredictably, making it challenging to plan ahead or maintain consistency. According to medical experts, managing triggers is an important part of reducing the frequency and intensity of flare ups.
Flare ups may feel different for each individual, but what all have in common is a sudden spike in discomfort or pain.
Common Symptoms During Flare Ups
Symptoms during a fibromyalgia flare up often include widespread muscle pain, chronic fatigue, and sleep disturbances. Many individuals also experience heightened sensitivity to touch, headaches, and difficulty concentrating.
For some, digestive issues like stomach pain and bloating are also present during a flare up. According to guides on fibromyalgia flare ups, both emotional and physical symptoms can worsen, such as anxiety, mood swings, and irritability.
These symptoms make it hard to function normally and may fluctuate in severity throughout the flare.
How Flare Ups Affect Daily Life
A flare up can significantly interfere with daily activities. Simple tasks like getting out of bed, cooking, or running errands may feel overwhelming for someone experiencing a flare.
Work, family responsibilities, and social plans might be disrupted or postponed frequently. During flares, some individuals may need to adjust their schedules, ask for support, or take time off work to manage their health.
The unpredictable nature of flares can also impact mental health, leading to increased stress and emotional strain. For more information, see the Cleveland Clinic’s overview of fibromyalgia flare ups.
The Link Between Fibromyalgia and Stomach Issues
The relationship between fibromyalgia and stomach issues is complex and often leads to uncomfortable symptoms during flare ups. Many individuals report a pattern of digestive distress, with symptoms ranging from mild discomfort to more severe abdominal pain and irregular bowel movements.
Gastrointestinal Symptoms in Flare Ups
People with fibromyalgia frequently experience a mix of gastrointestinal complaints. These often include stomach cramps, bloating, gas, diarrhea, constipation, and nausea. During fibromyalgia flare ups, these symptoms can intensify, affecting daily life and comfort.
The pain can feel similar to symptoms of irritable bowel syndrome (IBS). Reports indicate that up to two-thirds of people living with fibromyalgia experience abdominal pain or IBS-like symptoms, especially during periods of heightened fibromyalgia activity. Common triggers include stress, changes in routine, or new medications.
Bloating and discomfort are often present in the upper and lower abdomen. Many also find that their appetite can decrease or fluctuate, leading to additional nutritional concerns. These symptoms are not just inconvenient; they can lead to fatigue and interfere with sleep quality.
Possible Causes of Stomach Problems
Researchers have not pinpointed a single cause for stomach problems in fibromyalgia, but several factors appear to contribute. Altered pain perception in the nervous system may make the gut more sensitive, magnifying minor digestive issues.
Another aspect is the overlap between fibromyalgia and conditions like IBS. Some experts believe that the same imbalances in neurotransmitters that contribute to fibromyalgia pain may also affect gut motility and function. There’s also a noted connection to gut health, such as changes in the types of bacteria living in the digestive tract.
Other possible contributors include stress, which can worsen both pain and digestive symptoms, and the side effects of medications used to manage fibromyalgia. Poor sleep, which is common in fibromyalgia, can further disrupt digestive processes.
Prevalence of Digestive Distress
Digestive issues are strikingly common among people with fibromyalgia. Studies have shown that a substantial number of patients struggle with symptoms like abdominal pain, constipation, and bloating. It’s estimated that most individuals with fibromyalgia will experience some form of gastrointestinal problem during their lifetime.
In fact, one review described how the overlap between fibromyalgia and IBS symptoms is significant, making it difficult to separate the two conditions in many cases. A detailed discussion can be found at News-Medical’s article on fibromyalgia and gut health.
Other digestive disorders, such as GERD, are also seen more often in people with fibromyalgia, further increasing the overall burden of symptoms, according to Continental Hospitals’ overview of digestive disorders in fibromyalgia. Recognizing how common these problems are may help patients and providers seek more targeted relief.
Recognizing Stomach Symptoms During Flare Ups
Stomach symptoms are common in people experiencing fibromyalgia flare ups. These issues can range from pain and discomfort to changes in digestion and appetite, making daily life more challenging.
Abdominal Pain and Discomfort
Many individuals with fibromyalgia report frequent abdominal pain. This discomfort can vary from mild cramping to sharp, persistent aches. Some describe a deep, aching pain in the lower abdomen that is difficult to ignore.
Muscle tenderness and nerve sensitivity are thought to play a role in this pain. Pain may coincide with other symptoms, such as fatigue or headache. Often, these stomach pains appear suddenly and can linger for hours or even days during a flare up.
Some research suggests a link between fibromyalgia and conditions like irritable bowel syndrome (IBS), which may worsen abdominal discomfort. For further detail, fibromyalgia frequently co-occurs with IBS, causing pain and bloating.
Digestive Changes: Bloating, Gas, and Nausea
Digestive problems are frequently reported during flares. Bloating is a common concern; people often feel swollen or full, even after eating small amounts. The feeling of pressure or tightness in the stomach can cause additional discomfort.
Gas and excessive burping may also develop. These symptoms typically result from slowed or irregular gut movement, which is sometimes linked to fibromyalgia. Nausea can be mild or severe, sometimes interfering with meals and causing people to skip food entirely.
Symptoms Checklist:
- Persistent bloating
- Excessive gas or burping
- Nausea, especially after eating
These digestive symptoms can appear together or independently. For more on the connection between fibromyalgia and digestive issues, see this overview of common gastrointestinal symptoms in fibromyalgia.
Appetite Fluctuations
Flare ups often affect appetite in various ways. Some individuals notice decreased appetite, making it difficult to consume regular meals. This is often due to pain, nausea, or feelings of fullness and discomfort.
Others may experience intermittent increases in hunger, possibly as a response to fluctuating stomach activity or changes in digestive hormones. Appetite changes are unpredictable, often shifting throughout the day or from one flare to the next.
These irregular eating patterns may impact nutrition and energy levels. Monitoring these changes and keeping a food diary can help identify triggers. Individuals with fibromyalgia frequently report changes in bowel habits and appetite, which can add to the daily challenges of managing symptoms.
Triggers and Risk Factors for Stomach Flare Ups

Various factors can make stomach symptoms more likely or severe for people with fibromyalgia. Flare ups often come from a combination of daily habits, stress, and physical conditions.
Dietary Triggers
Certain foods and drinks can set off or worsen stomach pain and digestive symptoms in fibromyalgia. High-fat meals, artificial sweeteners, and processed foods are common culprits. Some individuals also react to gluten, dairy, or certain additives, leading to increased bloating or abdominal discomfort.
Excessive caffeine or alcohol can disrupt digestion and trigger symptoms. Spicy foods, carbonated drinks, and large meals sometimes create more stomach pain or indigestion, too. Keeping a food diary helps people track which items consistently cause trouble.
Eating smaller, balanced meals and choosing fresh, whole foods may improve digestive health. Hydration and mindful eating also play a key role for many managing fibromyalgia’s digestive challenges. For more details on food-related effects, visit this article on fibromyalgia stomach pain.
Stress and Emotional Factors
Mental stress is a significant trigger for stomach flare ups in fibromyalgia. Emotional distress can change how the gut functions, sometimes leading to nausea, cramping, or changes in bowel habits.
Stress can increase the body’s sensitivity to pain, making digestive discomfort feel worse during flares. Anxiety and depression are also linked to more frequent or severe gastrointestinal symptoms in some people with fibromyalgia.
Building daily stress management routines, such as deep breathing or light exercise, may help keep both pain and stomach issues in check. Support groups, therapy, or mindfulness meditation can be helpful for managing emotional triggers. This relationship between stress and flares is explained in more detail in this Medical News Today article.
Sleep Disturbances
Poor sleep or disrupted sleep patterns are common with fibromyalgia and can make stomach flare ups worse. Insufficient sleep can alter how the digestive system works, resulting in constipation, diarrhea, or increased abdominal pain.
Restless nights often coincide with more sensitivity in the gut, likely because the body’s ability to manage inflammation and pain is reduced when sleep is lacking. Even one night of poor rest may lead to more noticeable gastrointestinal complaints the next day.
Creating a regular sleep schedule, limiting screen time before bed, and making the bedroom comfortable for rest may reduce both pain and digestive symptoms. Strategies for better sleep can have a positive impact on how often stomach flares occur.
Medication Side Effects
Several medications used to manage fibromyalgia, such as pain relievers and antidepressants, may have digestive side effects. Nonsteroidal anti-inflammatory drugs (NSAIDs), for instance, sometimes cause stomach upset, ulcers, or diarrhea.
Some antidepressants and muscle relaxants can slow digestion or disrupt normal bowel patterns. Side effects like nausea, bloating, and constipation are not unusual and might be confused with fibromyalgia symptoms.
If medications are suspected of causing or worsening stomach flares, it’s important to discuss these issues with a doctor. Adjusting doses or switching prescriptions can often lessen digestive side effects while still providing symptom relief. A full list of possible medication effects is available in this WebMD overview on fibromyalgia.
Managing Stomach Symptoms During Fibromyalgia Flare Ups
Fibromyalgia commonly affects the digestive system, leading to issues such as bloating, diarrhea, and abdominal pain. Simple daily habits often play a critical role in reducing discomfort and improving overall gastrointestinal well-being.
Dietary Adjustments
Many people with fibromyalgia experience digestive problems like IBS, GERD, or frequent bloating. Paying close attention to what is eaten and how meals are timed may reduce these symptoms. It helps to create a food diary to identify which foods worsen stomach pain or discomfort.
Some individuals find that avoiding processed foods, excess sugar, caffeine, and high-fat meals makes a noticeable difference. Small, frequent meals instead of large ones can minimize bloating and cramping. Fiber-rich foods such as oats, brown rice, and certain fruits and vegetables support digestive health, but sudden increases in fiber should be avoided as they may trigger symptoms.
Hydration is especially important. Drinking plenty of water aids digestion and may ease constipation. For more information, see how stomach issues are linked to fibromyalgia at The Link Between Digestive Disorders and Fibromyalgia.
Gentle Physical Activity
Staying physically active is recommended to help manage fibromyalgia, but high-intensity activities should be avoided during flare-ups. Gentle exercises, such as stretching, yoga, or short walks, can help stimulate digestion and reduce the risk of constipation.
It’s best for people to listen to their bodies and choose activities that do not cause overexertion. Sessions can be broken up into shorter intervals throughout the day. Using a soft mat for stretching or practicing guided gentle yoga may provide both digestive and pain relief.
A short, gentle walk after meals helps improve gut motility without exhausting energy reserves. Regular movement—even in small doses—can make a noticeable difference in how the stomach feels during a flare.

Stress Management Techniques
Stress is known to worsen both fibromyalgia pain and digestive symptoms. Mindfulness practices such as deep breathing, meditation, or progressive muscle relaxation reduce tension and can ease stomach discomfort.
Cognitive behavioral therapy (CBT) has proven helpful for managing stress and fibromyalgia-related gut problems. Techniques from CBT can help individuals cope with flare-ups, reframe negative thoughts, and lessen anxiety linked to digestive issues.
Setting aside time for relaxation each day, whether through listening to calming music, taking a warm bath, or spending time in nature, can lower stress and support a healthier digestive response.
