    TLDR Insulin resistance is linked to PCOS and can lead to other health issues, but treatments like metformin can help manage symptoms.
    The document from 2005 explores the connection between insulin resistance and Polycystic Ovary Syndrome (PCOS), a condition affecting 5-10% of women of reproductive age. It discusses how hyperinsulinemia may stimulate excess ovarian androgen production, leading to PCOS symptoms and increasing the risk of type 2 diabetes and cardiovascular disease. Treatments like antiandrogens and insulin sensitizers such as metformin and thiazolidinediones were shown to be effective in reversing metabolic and ovarian abnormalities. The document also notes the importance of early detection and treatment of PCOS, especially in adolescents, and highlights a study by Dunaif et al. involving 21 subjects with PCOS treated with troglitazone, which improved insulin sensitivity and ameliorated hyperandrogenism. However, it emphasizes the need for further research with safe insulin sensitizers to normalize insulin sensitivity and ovarian function in young women and adolescents.

      community Sugar and Hair loss connections

      in Research/Science  41 upvotes 2 weeks ago
      High sugar diets may worsen hair loss by increasing 5α-reductase activity and androgen levels, especially in women with PCOS. A low sugar diet might reduce scalp DHT levels, similar to finasteride, but genetics also significantly influence hair loss.

      A 30-year-old female with PCOS and male pattern baldness is frustrated with her endocrinologist's recommendation of only Spironolactone and minoxidil, feeling that dutasteride, finasteride, and progesterone would be more effective. Other users suggest various online sources for treatments, warn against self-medicating due to potential risks, and recommend seeking a specialized endocrinologist or considering additional treatments like Inositol, Berberine, and dermaneedling.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
