Patient was educated on long-term complications of untreated Celiac disease as follows:

1. Loss of fluid volume in stool resulting in dehydration and poor skin turgor over time, secondary to poor absorption of water due to damage to the villi.
2. Malnutrition with extreme weight loss due to poor absorption of nutrients in the small intestine, due to damage to the villi.
3. Pale skin and mucus membranes, increasing shortness of breath, increased heart rate, and markedly limited endurance, secondary to iron deficiency anemia, due to poor absorption of iron in the small intestine.
4. Muscle cramps with weakened bones and osteoporosis over time, resulting in pathological fractures, due to poor absorption of calcium in the small intestine.
5. Irritability, fatigue, and in extreme cases, even seizures can occur due to the low calcium absorption in small intestine.
6. Tingling and numbness, secondary to hypocalcemia and vitamin B-complex deficiency and symptoms of depression and behavior changes with extreme shortness of breath and heart palpitations, due to poor absorption of vitamin B12 in the small intestine.
7. Prolonged course of celiac disease stands the risk of leading to small intestinal cancers with symptoms of bleeding into the intestines and acute intestinal obstructions.
