Diet and Vulvar Lichen Sclerosus
VLS can profoundly affect sexual life. In consultations, I discuss this with all my patients — because silence on this topic helps no one.
What We Really Know About Diet and VLS
Currently, there is no specific diet for vulvar lichen sclerosus supported by solid clinical evidence. International guidelines —ISSVD, BAD, EADV— do not make specific dietary recommendations for VLS because there is insufficient data to support them.
What does exist is evidence on the role of diet in autoimmune diseases in general. VLS is an autoimmune disease — and diet can influence the systemic inflammatory response, although not specifically for VLS.
That said, there is a tendency online to attribute effects to certain foods on VLS that are not proven. In my practice, I try to be honest: I will not recommend an “anti-lichen diet” that has no scientific basis. But I can offer guidance on eating habits that make sense in the context of an autoimmune disease with an inflammatory component.
What Makes Clinical Sense
General anti-inflammatory eating pattern. A diet rich in vegetables, fruits, legumes, whole grains, olive oil, and oily fish — known as the Mediterranean pattern — has documented systemic anti-inflammatory effects. There is no evidence that it specifically improves VLS, but there is also no reason not to recommend it as part of a healthy lifestyle.
Avoid being overweight. Obesity is associated with increased systemic inflammatory activity. In the context of VLS — a chronic inflammatory disease — maintaining a healthy weight makes sense as a general health measure.
Adequate hydration. Systemic hydration contributes to overall skin health. There is no specific data on its effect on VLS, but it is a general health recommendation with no adverse effects.
Unsubstantiated Claims About Diet and VLS
Many claims circulate online about foods that “worsen” or “improve” VLS: gluten, dairy, oxalates, sugar. None of these have solid clinical evidence in the specific context of VLS.
This does not mean that they cannot have some effect in individual cases — medicine is complex, and each patient is different. But it does mean that I cannot recommend them as the basis of a nutritional approach to VLS without supporting data.
If you wish to explore specific dietary changes, do so with the guidance of a dietitian-nutritionist who understands the context of your condition — not by following unsupervised internet protocols.
