Unlike many digestive disorders, autoimmune gastritis does not always begin with obvious stomach pain or severe indigestion. In fact, many people experience symptoms that seem unrelated to the stomach. Persistent fatigue, unexplained weakness, brain fog, dizziness, pale skin, hair loss, tingling or numbness in the hands and feet, and recurring iron deficiency may be among the earliest warning signs. These symptoms are often caused by nutrient deficiencies rather than the stomach inflammation itself.
