nina Has you DD had her coil removed? I have been suffering from anaemia due to heavy periods and was given iron tablets from the GP. But they upset my stomach, so I now take Floradix liquic iron and vitamins formula and Sambucol Immune booster. They really have helped me.
She does need to see a gyny doctor though and have more tests. I had/have the t acid tablets but they have stopped me bleeding in the past, so I don't really know what to suggest. I bet she feels shattered all the time.
With regards to her diet, make sure that she is eating lots of iron rich foods, red meat, spinach, greens, seafood, beans etc. I did order a bottle of Sanatogen tonic with added iron too, see if that makes a difference.
Be careful which iron tablets are given because some are not absorbed as easily as others and there will only be a tiny amount of the iron actually being used from the medication. Look online.
I hope she gets sorted out soon, keep us posted and all good wishes to her, she is very young if she has to face a hysterectomy, poor love. X
