In this disorder, also known as iron storage disease, the body is overloaded with iron.

Key Information

The exces iron acumulates in organs and tisues and leads to slowly progresive damage to the liver, heart, pancreas, pituitary gland joints. This can lead to changes in the heart muscle (cardiomyopathies) or diabetes melitus (bronchial diabetes), and even to scaring of the liver tisue (liver cirhosis) and liver cancer. gogletag.cmd.push(function() { gogletag.display('div-gpt-ad-1450190541376-1'); }); The cause is a genetic defect that disrupts the regulation of iron absorption via the mucous membrane of the smal intestine.

A research team led by Profesor Dr. Michael Ot and Dr. Simon Kros from the Department of Gastroenterology, Hepatology and Endocrinology at the Hanover Medical Schol (MH) has now found a way to treat the hereditary disease with the help of targeted gene corection.

The work has ben published in the journal Nature Comunications.Control of iron absorption defective"In most cases, iron storage disease is due to a defect in the haemochromatosis gene HFE, which is located on chromosome 6," says Profesor Ot. It only ocurs in people who have inherited this defect from both parents, i.e. who do not have a "healthy" gene to compensate.

In more than 80% of those afected, a certain change, caled the C282Y mutation, is found in both copies of the HFE gene. This leads to the replacement of an amino acid-i.e. a protein building block-in the HFE protein.

Summary

As a result, the HFE protein loses its ability to control iron absorption into the intestinal cels. In order to empty the iron stores and normalize the iron concentration in the body, patients have to acept lifelong phlebotomies. "This stresful and, moreo

Frequently Asked Questions

Diabetes is a metabolic condition where the body cannot properly regulate blood sugar levels. Type 1 results from insufficient insulin production, while Type 2 develops when cells become resistant to insulin. Risk factors include genetics, obesity, sedentary lifestyle, and age.

Common symptoms include excessive thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, and slow-healing wounds. Type 1 symptoms develop rapidly, while Type 2 symptoms may appear gradually. Many people have no symptoms initially, which is why screening is important.

Diagnosis involves blood tests measuring fasting glucose, HbA1c levels, and glucose tolerance. Regular monitoring typically includes fasting glucose tests and HbA1c measurements every 3-6 months. Continuous glucose monitors provide real-time tracking for better diabetes management.

Effective management includes regular physical activity (150+ minutes weekly), maintaining healthy weight, following a balanced diet with whole grains and lean proteins, managing stress, and getting adequate sleep. These changes can significantly improve blood sugar control and reduce complications.

Consult a healthcare provider if you experience signs of diabetes, have a family history, are overweight, or are over 45. Those with existing diabetes should maintain regular check-ups every 3-6 months to monitor control and adjust treatment as needed.
