What are the common symptoms of celiac disease?

Celiac disease can present a wide range of symptoms. The symptoms can vary from person to person. One might not even notice the disease, while someone else will experience a lot of discomfort.

The common symptoms of celiac disease include:

  • abdominal pain,
  • gases,
  • bloating,
  • chronic constipation or diarrhea,
  • weight loss,
  • fatigue,
  • foul-smelling stool [4, 5].

However, celiac disease can also have other influences on the body. It can lead to iron deficiency, joint pain, and weak bones.

Also, celiac disease can have a dermal presentation, called dermatitis herpetiformis. This dermatological condition affects roughly 25% of celiac-ill people. It causes itchy skin rushes that consist of blisters filled with clean fluid. Specific locations of the rush are the elbows, keens, and buttocks [4].

Is blood in stool in celiac disease dangerous?

Blood in the stool in celiac disease can occur. However, it is uncommon.

Blood in stool in celiac disease is normally not a dangerous condition. The amount of blood being possibly lost that way is typically not dangerous [1].

However, even tiny regular bleeding combined with celiac disease can contribute to the development of iron-deficiency anemia [3].

Additionally, in rare cases, celiac disease can lead to coagulopathy. In this condition, the clot formation ability is impaired. The coagulopathy can present in blood in the stool and can be life-threatening [6].

Should I see a doctor when I have blood in my stool with celiac disease?

Blood in stool is not common in celiac disease. However, blood in the stool can be a sign of developing a coagulopathy. This condition can be dangerous for you, and you should see your doctor as soon as possible.

Furthermore, you should check with your doctor if you have not developed iron-deficiency anemia. This can be possible, especially when you have noticed a recent growing fatigue.

Also, you may have another condition that causes bleeding in the gastrointestinal tract. Many dangerous conditions can lead to blood in stool [7]. Especially when you find a lot of blood in the stool, you should see your doctor to identify and treat the cause.
