SLC40A1 and obesity due to melanocortin 4 receptor deficiency: Obesity and iron deficiency are intertwined.2 Obesity induced inflammation increases hepcidin (iron metabolism regulating protein) concentrations, resulting in reduced iron absorption in intestine or inhibits iron uptake by ferroportin, a cellular iron exporter, from hepatocytes, macrophages and intestinal cells.17 It was supported by higher frequency of microcytic hypochromic and normocytic normochromic anaemia among overweight/obese FMS.
