Iron status affects coeliac disease risk
We conducted a study exploring whether iron deficiency might influence the development of coeliac disease through a method called Mendelian randomization. By analyzing genetic data from nearly 337,000 individuals, we discovered a link between lower iron levels and a higher risk of coeliac disease.

The findings suggest that maintaining good iron status could be vital in preventing this condition. However, while our results are promising, they do not establish a definitive cause-and-effect relationship.

Iron supplementation not significantly beneficial
We examined the effectiveness of iron supplementation in children with newly diagnosed celiac disease who have iron deficiency. Our study reviewed the ferritin levels of these kids on a gluten-free diet over a year.

Interestingly, we found that both those taking iron and those not taking it showed significant increases in ferritin levels. However, there was no marked difference in the outcomes between the two groups. Most importantly, children who adhered to a gluten-free diet tended to normalize their ferritin levels without needing iron supplements.

We explored how iron deficiency and anemia affect individuals diagnosed with celiac disease (CeD) and the role of a gluten-free diet (GFD) in treating these issues. In a study of 572 patients, about 25% had anemia at the time of diagnosis, with iron deficiency being a major cause.

Interestingly, nearly 90% of those with anemia saw their hemoglobin levels return to normal after two years on a GFD. This suggests a positive response to dietary changes, helping many restore their health through improved nutrition.

Effective celiac solution
12 people found this helpful
Iron in bisglycinate form has excellent absorption. It is the only remedy that effectively treats iron deficiency in celiac patients. It raised my ferritin levels remarkably, from 9 to 34, when taken with vitamin C. I highly recommend it for those experiencing similar issues.

Significant ferritin rise
5 people found this helpful
An excellent variant of chelated iron, my 9-year-old child, who has celiac disease, takes one capsule regularly, twice a year for four months, with breaks in between. This product is gluten and lactose-free, which is important. Ferritin levels rose from 11 to 20 in four months. If hemoglobin is normal, it doesn't mean iron levels are sufficient. The body requires iron constantly, but with conditions like celiac disease, dietary iron is often insufficient.

Gentle and effective

I have been using Solgar Gentle Iron and have found it extremely beneficial in managing my anaemia. Unlike other iron supplements I've tried, it is gentle on my stomach and intestines, which is crucial for someone with celiac disease. It doesn't cause the nausea or stomach pains that are often associated with iron supplements. Incorporating it into my daily routine has been seamless. Ordering through the iHerb app is incredibly convenient—the app is user-friendly, and delivery is always fast. I highly recommend Solgar Gentle Iron and the iHerb service!

Atypical celiac disease presented effectively
We reported a case of a 30-year-old woman who experienced unexplained weight loss, menstrual irregularities, and severe fatigue, leading to a diagnosis of celiac disease (CD). Interestingly, her symptoms were atypical and lacked the usual gastrointestinal signs.

Through a strict gluten-free diet and supplementation of essential vitamins and minerals like iron and folate, she exhibited remarkable improvement within three months, regaining hemoglobin levels and restoring her menstrual cycle.

This case emphasizes the importance of recognizing atypical presentations of CD, as they can often lead to under-diagnosis of this complex condition.

We conducted an international study involving 137 patients with ultra-short coeliac disease (USCD) to understand its characteristics compared to conventional coeliac disease.

Our findings revealed that USCD patients were younger and had overall similar symptoms, but experienced less iron deficiency. Despite these differences, both groups showed similar improvements in health after starting a gluten-free diet.

This research highlights the importance of careful diagnostic sampling in the duodenal bulb for better identification of this unique condition.

We examined the prevalence of anemia in patients with Celiac Disease (CD) before and after they started a gluten-free diet (GFD). Through our cross-sectional study, we gathered blood data from 311 participants over the years, revealing that 17.8% of adults and 4.4% of children still struggled with anemia even after several years on the GFD.

While adults showed some improvement over time, with anemia rates dropping from 24% to 17.8%, the underlying issues, such as diagnostic delays and severe gut damage, could explain why anemia persists for some patients.
