A recent systemic review looked at the effect of dietary changes on pain perception in endometriosis. While the researchers went through 2185 studies, only six studies fulfilled their inclusion criteria (reproductive age; laparoscopically confirmed endometriosis; and intervention including any type of dietary change) (Sverrisdóttir, Hansen, & Rudnicki, 2022). Those six studies showed that dietary changes, such as “high intake of polyunsaturated fatty acids, a gluten-free diet and a low nickel diet,” may improve painful endometriosis (Sverrisdóttir, Hansen, & Rudnicki, 2022).
Another study created a short algorithm for dietary suggestions for those with endometriosis. They recommended overall the Mediterranean diet or an antioxidant diet- rich in vitamins, minerals, and polyunsaturated fats (Nirgianakis et al., 2021). For those who have gastrointestinal symptoms, they further recommend a gluten free, low FODMAP, or for a short time low nickel diet (Nirgianakis et al., 2021).
As far as dietary supplements go, a review by Bahat et al. (2022) reports that “magnesium, curcumin, resveratrol, and ECGC were beneficial in animal studies due to their antiangiogenic effects. ” Bahat et al. (2022) also states that “omega 3 and alpha-lipoic acid improved endometriosis-associated pain in human studies” as well as “curcumin, omega 3, NAC, vitamin C, and ECGC supplementation decreased endometriotic lesion size in animal and human studies.” The authors do caution that “low sample size and experimental study design” limits the quality of the evidence and urge that “one should keep in mind that food resources and pharmacological formulas of supplements may have different mechanisms of actions” (Bahat et al., 2022).
