I have a female patient whose age is 30 yrs. Her hb % is around 7.5 g/dl since last 6 months. Her recent blood report is as follow- hb - 7.7 g/ dl iron studies serum (tptz) - 21.50 micro gram/dl total iron binding capacity - 340.50 micro gram /dl transferrin saturation -. 6.31%. Her treatment for iron deficiency has been done by prescribing iron tablets (cap autrin) and diet which is rich in iron. Since last 6 months. But her hb% and iron studies not improved at all. Patient complain is general weakness and a little breathlessness on mild to moderate walking. Please advice where and which short of treatment she needed. Thanks
