How fast do ferritin levels fall after iron infusions for anemia? Ferritin went up to 222 after iron, but 7 weeks later was at 99. Is this typical?

In brief: Probably

Iron is being utilized in the manufacture of hemoglobin and redistribution of iron in the body may explain the fall.
Your ferritin is still in the normal range. You may consult this site for info: https://medlineplus.gov/ency/article/003490.htm For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
