Can iv iron cause weight gain?

For the past few months, I've been getting IV iron infusions for my severe anemia. While my energy has improved, I've also noticed a slight weight gain. Is it possible for IV iron treatments to cause weight gain?

My mother was worried that taking IV iron would make me put on weight, but my doctor clearly explained that iron itself has zero calories. Actually, once your low iron gets fixed, your energy levels improve, which might slightly increase your appetite. But it is very safe, so please follow your doctor's advice.

Haha, if iron infusions caused weight gain, I would be as heavy as a railway track by now! Don't worry, it is just correcting your blood levels, not adding butter to your diet. Keep calm and get your infusion done.

I completely understand why you are anxious about this, as I also panic over every minor change in my body. I had to get two sessions of IV iron last year and was terrified of gaining weight, but honestly, nothing happened. It actually gave me back the energy to start walking and staying active again.

There is no clinical evidence linking intravenous iron therapy to long-term weight gain. Some patients report mild, transient fluid retention or bloating post-infusion, which resolves quickly. Your physician is the best person to address any concerns regarding your therapy and metabolic health.

Actually, IV iron doesn't cause weight gain, yaar. Some people feel a bit bloated right after the infusion, which might look like weight gain on the scale, but it is just temporary water retention. Don't worry, it goes away in a couple of days.
