Affecting an estimated 5-15% of lactating individuals, CLI can stem from both extrinsic factors (e.g., infant feeding challenges) and intrinsic ones (e.g., endocrine or metabolic disorders). This qualitative study explored the lived experiences of individuals with CLI and their interactions with healthcare providers (HCPs). <b><i>Methods:</i></b> In-depth, semi-structured interviews were conducted with 30 individuals who self-reported experiencing low milk supply, were 18 or older, and were members of the \"IGT and Low Milk Supply Support Group\" on Facebook, which has approximately 10,700 members. Data were analyzed using phronetic iterative analysis which is a cyclical, reflexive coding approach that emphasizes practical reasoning. <b><i>Results:</i></b> Participants reported significant challenges, including: (1) not being believed or taken seriously; (2) facing discrepancies between providers that led to fragmented care; and (3) experiencing a lack of knowledge from HCPs, including lactation consultants. Many described actively seeking a diagnosis and meaningful support but instead receiving inconsistent advice and little to no diagnostic insight into their condition. <b><i>Conclusions:</i></b> These findings highlight the urgent need for improved education and training among HCPs to address the complex realities of CLI. They also point to the importance of advancing personalized approaches to breastfeeding support and expanding research to determine causes and diagnostics for low milk supply. By centering patient voices, this study identifies critical gaps in care and communication that prevent effective support for those navigating CLI.</p>","PeriodicalId":9142,"journal":{"name":"Breastfeeding Medicine","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143779074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Systematic reviews have suggested the role of breastfeeding in the prevention against asthma, autoimmune diseases, inflammatory bowel disease, and childhood leukemia.

Randomized controlled trials (RCTs) are not possible for ethical reasons. In addition, epidemiological studies have not considered that there is a large interindividual variation in human milk (HM) composition and feeding at the breast versus pumped HM potentially impacting the effect of breastfeeding between mothers. While prevention strategies such as early introduction of highly allergenic food are impactful in preventing peanut and egg allergies, implementation of early introduction guidelines has been slow, and many infants are already sensitized by 4-6 months of age. To be more effective, primary prevention strategies must commence much earlier, during breastfeeding.
