Hereditary telegnastia is linked to which deficiency?

Hereditary telangiectasia, also known as hereditary hemorrhagic telangiectasia (HHT), is a genetic disorder that affects blood vessel formation, leading to the development of abnormal blood vessels. The hallmark of this condition is the presence of telangiectasias which are small, dilated blood vessels that can form on the skin and mucous membranes.

Iron deficiency is significant in the context of hereditary telangiectasia because individuals with this condition may experience frequent bleeding from these abnormal blood vessels, particularly in the gastrointestinal tract and other areas. This bleeding can lead to chronic blood loss and, consequently, iron deficiency anemia. Therefore, individuals with hereditary telangiectasia may exhibit signs of iron deficiency due to the repeated blood loss associated with their condition.

The other deficiencies listed do not have the same direct relationship with hereditary telangiectasia. Vitamin B12 deficiency is more associated with neurological issues and certain types of anemia, iodine deficiency typically affects thyroid function and metabolism, and calcium deficiency relates to bone health and does not connect to the vascular abnormalities seen in hereditary telangiectasia. Thus, iron deficiency is the most relevant deficiency linked to the complications of hereditary telangiectasia.
