I need help. I am losing weight.

Women, 33 years, 42 kg and 163 cm.

I suffer from unexplained and debilitating fatigue. My blood tests show iron and vitamin B9 deficiency. I am losing weight.

So far, ruled out:

· No celiac disease.

· Fecal calprotectin and fecal elastase are normal.

· No parasites in stool.

· Negative for Helicobacter pylori.

· No fat in stool.

Positive diagnoses:

· Gastritis with reactive lymphoid aggregates in the lamina propria.

· Low pepsinogen I and low pepsinogen I/II ratio, normal gastrin.

· Undigested food in stool.

Antacids worsen my symptoms.
