If you’ve been living with an autoimmune condition, chances are you’ve heard the phrase “everything starts in the gut.” But what does that really mean, and can gut health really impact how your immune system behaves?

The short answer is yes. The longer answer is more complex, and it’s changing fast as science learns more about the powerful role the gut plays in chronic illness.

Your gut is more than just digestion

Inside your digestive tract lives a thriving community of trillions of microbes. This ecosystem, called the gut microbiome, helps you digest food, absorb nutrients, and most importantly, interact with your immune system.

In fact, most of your immune cells live in or around your gut. This means the balance of good and bad bacteria in your microbiome can help keep inflammation under control, or trigger an immune response if things get out of balance.

When gut health breaks down

For people with autoimmune diseases like lupus, rheumatoid arthritis, or Sjögren’s syndrome, gut dysfunction may play a role in symptom flares. Researchers have found that people with autoimmune conditions often show signs of dysbiosis, an imbalance of the gut microbiome.

This may not cause autoimmune disease on its own, but it can worsen inflammation or affect how well you respond to treatment. Signs your gut may be struggling include:

• Frequent bloating or gas
• Irregular bowel habits
• Unexplained fatigue or brain fog
• New food sensitivities

Small changes, big impact

The good news? You don’t need a complete overhaul to support your gut health. Even small, consistent changes can help.

• Add more plants to your plate: Fiber feeds good bacteria
• Include fermented foods like yogurt, kefir, sauerkraut, or miso
• Drink plenty of water to keep digestion moving
• Talk with your doctor before starting probiotics
• Reduce stress, which can disrupt the gut-immune connection

Listening to your body matters

You may already be more in tune with your body than most people. Living with an autoimmune disease often means you notice subtle changes sooner. If you suspect your gut health is affecting how you feel, bring it up with your provider. There may be ways to adjust your plan that support both your digestion and your immune system.

Sometimes healing starts from the inside out, and the gut is a great place to begin.
