Whats the evidence for thinning the womb lining before surgery to remove it?
There’s good evidence that thinning the lining of the womb before surgery to remove it helps women with heavy periods.[1] The research comes from good quality studies (called randomised controlled trials).References Sowter MC, Lethaby A, Singla AA. Pre-operative endometrial thinning agents before endometrial destruction for heavy menstrual bleeding (Cochrane review). In: The Cochrane Library. Wiley, Chichester, UK. Glossary randomised controlled trials Randomised controlled trials are medical studies designed to test whether a treatment works. Patients are split into groups. One group is given the treatment being tested (for example, an antidepressant drug) while another group (called the comparison or control group) is given an alternative treatment. This could be a different type of drug or a dummy treatment (a placebo). Researchers then compare the effects of the different treatments.
