We often associate gut health with obvious things like bloating, gas, or heartburn. But according to Dr. Angelina Alejandro, your gut—a complex ecosystem of trillions of bacteria known as the microbiome—is the control center for far more than digestion. When your gut is out of balance (a state often called dysbiosis), it sends out subtle, "sneaky" signals across your entire body.

Autoimmune diseases—like Rheumatoid Arthritis, Lupus, Hashimoto’s Thyroiditis, and Multiple Sclerosis—are notoriously difficult to diagnose in their early stages because their symptoms are so nonspecific. They look like everything and nothing all at once. If you are chronically searching for answers, pay close attention to these common, yet often overlooked, signs of systemic immune dysfunction.
