Is Your Weight Loss Jab Triggering Autoimmune Disease? What to Know About GLP‑1 Side Effects
by Lucia Stansbie
Ozempic and similar medications—often called weight loss jabs—are gaining popularity for rapid results. These drugs, part of a class called GLP‑1 receptor agonists, were originally designed for type 2 diabetes. But as they became known for helping people shed significant weight, they’ve sparked a new wave of interest from non-diabetics eager to slim down.
However, new research suggests that the benefits may come with hidden costs—especially for those prone to autoimmune diseases.
What Are GLP‑1 Medications Like Ozempic?
GLP‑1 (glucagon-like peptide-1) is a hormone that helps regulate blood sugar and appetite. Medications like Ozempic (semaglutide), Wegovy, and Mounjaro mimic this hormone to:
Enhance insulin secretion
Reduce appetite
Slow stomach emptying
Promote weight loss
They’ve been hailed as game-changers for obesity—but GLP‑1 side effects may go beyond the usual nausea or fatigue.
New Concerns: Could Ozempic Trigger Autoimmunity?
A recent study analyzing over 580,000 adults found that those on GLP‑1 receptor agonists had a higher risk of developing autoimmune conditions compared to those taking other diabetes drugs. The most commonly observed autoimmune issues included:
Ulcerative colitis
Autoimmune thyroiditis
Rheumatoid arthritis
Psoriasis
Ankylosing spondylitis
The risks were modest but consistent—raising questions about whether weight loss jabs could trigger autoimmune disease in people who are genetically or environmentally susceptible.
What Is Autoimmune Disease?
Autoimmune diseases occur when the immune system mistakenly attacks healthy tissue. Common types include Hashimoto’s thyroiditis, lupus, Crohn’s disease, and multiple sclerosis.
Symptoms may include:
Fatigue
Joint or muscle pain
Digestive issues
Rashes or skin problems
While GLP‑1 medications aren’t proven to cause autoimmunity, they appear to modulate immune activity—sometimes dampening inflammation, other times triggering unwanted immune responses.
Should You Be Worried?
If you’re considering Ozempic purely for weight loss, especially without medical supervision, it’s important to weigh the long-term consequences. Ask yourself:
Do I have a family history of autoimmune disease?
Have I ever had unexplained inflammation, gut issues, or fatigue?
Am I using this drug as a quick fix rather than addressing root causes?
These medications may be safe for many, but GLP‑1 side effects may not be immediately obvious—and autoimmune disorders can develop subtly over time.
Nutritionist’s Advice: Support Your Body Holistically
Before turning to Ozempic for weight loss, consider:
Anti-inflammatory nutrition (e.g., leafy greens, omega‑3s, fermented foods)
Addressing gut health and hormonal balance naturally
Speaking with your healthcare provider if you have immune system concerns
Weight loss is not just about numbers—it’s about long-term wellness. Don’t trade one health issue for another.
