Celiac Disease Symptoms: Anemia

What is Anemia?

Anemia, also called iron deficiency anemia, is a decrease in red blood cells due to a lack of iron. Anemia is extremely common, especially in women. Anemia is also common in those with undiagnosed celiac disease. It can have many causes, including iron, folate, or Vitamin B12 deficiencies. These deficiencies can be related to the malabsorption caused by celiac disease. People who have anemia may feel tired, fatigued, or weak. They may also have shortness of breath or be unable to exercise normally. Do not add iron supplements without consulting your healthcare provider first. Anemia should be addressed by a medical professional to identify and treat the root cause and to monitor iron levels during treatment.

What is the Connection between Celiac Disease and Anemia?

  • Anemia is widespread in those with undiagnosed celiac disease. Some people feel symptoms of anemia, while others may not.
  • The part of the small intestine where iron is absorbed is the same area that is damaged when gluten is ingested when people have undiagnosed celiac disease.
  • Those with unexplained anemia should be screened for celiac disease.
  • Anemia dramatically improves on a strict gluten-free diet. However, it may take time to correct the deficiency completely.
  • Learn more about the connection between celiac disease and anemia from Peter Green, M.D., from the Celiac Disease Center at Columbia University in this podcast:

Other Nutritional Deficiencies in People with Celiac Disease:

Untreated celiac disease can cause different degrees of malabsorption in each individual. This typically leads to lower-than-normal levels of essential nutrients, such as:

  • Calcium
  • Vitamin D
  • Iron
  • Folate
  • Vitamin B12
  • Copper
  • Magnesium
  • Zinc

Vitamin deficiencies may continue on a gluten-free diet, so taking a gluten-free multivitamin may be a good idea. Specific vitamins and minerals may also be necessary to correct more severe deficiencies. Discuss any vitamin and mineral supplements with your doctor or dietitian before taking them.

What is the Connection between Non-Celiac Gluten Sensitivity and Anemia?

A few reported cases of anemia as a symptom of non-celiac gluten sensitivity exist. It’s currently unclear if NCGS directly causes it. There is ongoing research to investigate this potential connection.


How Do People with Celiac Disease Experience Anemia?

A venous hum drove me crazy while I was in high school; I struggled to concentrate in class. After a year or two of trying to figure out what was causing the constant humming sound, I was told I had a venous hum as a result of severe anemia. This was my first clinical indication of celiac disease.
