Your iron studies confirm iron deficiency, with a low serum iron and a transferrin saturation under 4%, well below the normal range. This pattern, together with your low body weight and loss of appetite, suggests you're not getting or absorbing enough iron and overall nutrition, not just a standalone iron problem.
Next Steps
Please see a physician or gynaecologist in person so they can prescribe the right iron supplement and dose for you, and check what's behind both the appetite loss and your weight. Your
complete blood count has a few flagged values too, so take the original reports along for a direct interpretation.
Health Tips
Don't start an iron supplement on your own, since too much iron without proper evaluation can cause its own problems. See a doctor soon if the weight loss or poor appetite continues.
