Fibroids can shrink for any number of reasons.  Herbal and other supplements, like enzymes, are touted as shrinking fibroids because one woman's fibroids shrank while she took the supplement.  Some women have shrunk their fibroids with prayer.  Many women find relief from using various supplements.  One study showed that about 20% of the women incidentally in the study had fibroid shrinkage with no apparent cause for the shrinkage.

The aim of this study was to assess the feasibility and efficacy of laparoscopic myomectomy (LM) for large myomas. A subpopulation of 51 patients with myomas 8 cm or larger in diameter was selected from 155 patients who underwent LM at Kangbuk Samsung Hospital from July 2003 to November 2006. The mean age of the patients was 34.9±5.6 yr, mean parity was 0.6±0.9, and 8 patients had a previous operative history.

Women with uterine fibroids should be aware of the very serious implications of anemia and need to watch out for signs of this potential killer.  Anemia for women with fibroids begins with heavy cycles.  The earliest sign of anemia is often fatigue.  Feeling cold and nauseated are signs that anemia is progressing to a level that requires some form of treatment or at least regular monitoring.
