People with fibromyalgia already face daily challenges such as chronic pain, fatigue, and brain fog. However, many also notice that they catch colds and flu more frequently, and when they do, recovery takes longer than usual.
This increased susceptibility to infections can make living with fibromyalgia even more difficult. But why does this happen, and what can be done to support immune function?
This article explores the connection between fibromyalgia and a weakened immune system, possible causes of frequent illness, and natural ways to strengthen immunity.
1. Why Are People with Fibromyalgia More Likely to Get Colds and Flu?
While fibromyalgia is not classified as an autoimmune disease, many patients report immune system dysfunction that makes them more prone to infections.
There are several reasons why fibromyalgia patients tend to catch colds and flu more often:
1. Chronic Immune System Dysfunction
✔ The immune system is responsible for defending the body against viruses and bacteria.
✔ In fibromyalgia, the immune response may be underactive or overactive, leading to poor protection against infections.
✔ Studies suggest that natural killer (NK) cell activity is reduced in fibromyalgia patients, which may contribute to a weakened immune response.
2. Persistent Stress and Elevated Cortisol Levels
✔ Chronic stress weakens the immune system over time.
✔ Many fibromyalgia patients experience constant physical and emotional stress, which can suppress white blood cell production, making it harder to fight off viruses.
✔ Cortisol imbalance due to stress can lead to higher inflammation and increased susceptibility to infections.
3. Poor Sleep Quality and Reduced Healing Ability
✔ Deep sleep is essential for immune function, but fibromyalgia patients often suffer from insomnia, restless sleep, or sleep apnea.
✔ Without enough restorative sleep, the body produces fewer infection–fighting antibodies, making colds and flu more frequent and severe.
4. Nutrient Deficiencies Affecting Immunity
✔ Many fibromyalgia patients have low levels of essential immune-supporting nutrients, including:
- Vitamin D (critical for immune response)
- Zinc (helps fight infections)
- Magnesium (supports immune function and reduces inflammation)
- B vitamins (important for energy and immune health)
✔ A lack of these nutrients can weaken the body’s defense against infections, making colds and flu more frequent.
5. Increased Inflammation and Overactive Pain Responses
✔ Chronic inflammation in fibromyalgia can overburden the immune system, making it less effective at fighting infections.
✔ Many fibromyalgia patients report that when they get sick, their pain worsens, suggesting that the body’s inflammatory response is heightened.
6. Gut Health Issues and Poor Microbiome Balance
✔ The gut microbiome plays a crucial role in immune function.
✔ Fibromyalgia patients often suffer from irritable bowel syndrome (IBS), leaky gut, or bacterial imbalances, all of which can weaken the immune system.
2. How Colds and Flu Affect People with Fibromyalgia Differently
Not only do fibromyalgia patients catch colds and flu more frequently, but they also experience more severe symptoms and longer recovery times.
Here’s how viral infections affect fibromyalgia patients:
1. Increased Pain and Muscle Aches
✔ Flu-like muscle aches can be even worse for fibromyalgia patients, as their nervous system is already sensitive to pain.
✔ Body-wide soreness can trigger fibromyalgia flares, making it difficult to recover.
2. Extreme Fatigue and Weakness
✔ Colds and flu already cause fatigue, but in fibromyalgia, this exhaustion can last for weeks.
✔ Even after other symptoms subside, fibromyalgia patients may feel drained and weak for much longer than usual.
3. Prolonged Recovery Time
✔ While most people recover from colds or flu within a week or two, fibromyalgia patients may take much longer to feel normal again.
✔ This slow recovery is due to immune dysfunction, poor sleep, and heightened pain sensitivity.
4. Increased Sensitivity to Fevers and Chills
✔ Many fibromyalgia patients have difficulty regulating body temperature, leading to worsened chills, night sweats, and fever discomfort.
3. How to Strengthen Your Immune System and Reduce Illness Frequency
Although fibromyalgia can make the immune system more vulnerable, there are several natural ways to support immunity and reduce the frequency of colds and flu.
1. Prioritize Quality Sleep
✔ Aim for 7-9 hours of deep, restorative sleep each night.
✔ Try magnesium, melatonin, or herbal teas to support relaxation.
✔ Establish a consistent sleep schedule to help the immune system function properly.
2. Reduce Stress and Support Adrenal Health
✔ Practice deep breathing, yoga, or meditation to lower stress.
✔ Engage in gentle movement exercises to reduce stress hormones.
✔ Limit caffeine and sugar, which can stress the adrenal glands and weaken immunity.
3. Optimize Nutrition for Immune Health
✔ Eat an anti-inflammatory diet rich in:
- Leafy greens, citrus fruits, garlic, and ginger (immune-boosting foods)
- Bone broth and collagen (support gut and immune function)
- Lean proteins and healthy fats to maintain strength
✔ Consider supplements like: - Vitamin D (crucial for immunity)
- Zinc (boosts white blood cell function)
- Probiotics (supports gut health and immune defense)
4. Stay Hydrated and Support Detoxification
✔ Drink plenty of water to flush out toxins and keep the body hydrated.
✔ Try warm herbal teas like echinacea or elderberry to strengthen the immune response.
5. Gentle Exercise to Boost Circulation
✔ Engage in low-impact activities like walking, stretching, or tai chi to improve circulation and immune function.
✔ Avoid overexertion, as excessive exercise can increase fatigue and suppress immunity.
6. Support Gut Health
✔ Take probiotics and eat fermented foods like yogurt, kimchi, or sauerkraut.
✔ Reduce processed foods, gluten, and dairy if they cause inflammation.
4. When to Seek Medical Attention
If you experience frequent infections or have difficulty recovering from colds and flu, it’s important to speak with a doctor.
Signs that require medical attention include:
✔ Frequent fevers, swollen lymph nodes, or persistent infections
✔ Extreme fatigue lasting weeks after an illness
✔ Unusual immune reactions or slow healing wounds
✔ Difficulty breathing or severe flu complications
A doctor can check for immune deficiencies, underlying infections, or nutritional imbalances that may be contributing to frequent illnesses.
5. Conclusion: Managing Susceptibility to Colds and Flu in Fibromyalgia
People with fibromyalgia are more vulnerable to colds and flu due to immune dysfunction, poor sleep, high stress levels, and nutritional deficiencies.
By supporting immune function through proper sleep, stress reduction, nutrient optimization, and gut health, fibromyalgia patients can reduce the frequency and severity of infections.
If you often get sick or take longer to recover, consider working with a doctor to identify potential immune imbalances and develop a personalized wellness plan.
