“Deficiencies and Disorders: The Hidden Link Between Calcium, Vitamin D, and PCOS”

Review Article: Calcium and Vitamin D Deficiency in PCOS—Understanding the Impact and Potential Therapeutic Benefits

Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder affecting millions of women worldwide, characterized by irregular menstrual cycles, excess androgen levels, and polycystic ovaries. Recent research highlights the prevalence of calcium and vitamin D deficiencies among women with PCOS, which may exacerbate symptoms such as insulin resistance, menstrual irregularities, and metabolic disturbances. This review aims to explore the relationship between calcium and vitamin D deficiencies and PCOS, as well as the potential therapeutic benefits of supplementation.

Introduction to PCOS

PCOS is a multifaceted disorder with hormonal, metabolic, and reproductive implications. It affects approximately 8-13% of women of reproductive age and is linked to insulin resistance, obesity, and an increased risk of cardiovascular diseases. The exact cause of PCOS remains unclear, but lifestyle factors and nutritional deficiencies, including calcium and vitamin D, may play a role in its pathophysiology.

Prevalence of Calcium and Vitamin D Deficiency in PCOS

Vitamin D deficiency is particularly common among women with PCOS, with studies indicating that 67-85% have serum concentrations below 20 ng/mL4. Calcium deficiency, often coexisting with vitamin D deficiency, can further complicate metabolic and reproductive health. A study found that 83% of PCOS patients showed vitamin D deficiency, with 35% being severely deficient1.

Impact of Deficiencies on PCOS Symptoms

Calcium and vitamin D deficiencies can exacerbate PCOS symptoms:

Menstrual Irregularities: Vitamin D deficiency is linked to ovulatory and menstrual irregularities, potentially worsening fertility issues4.
Insulin Resistance: Lower vitamin D levels are associated with increased insulin resistance, a hallmark of PCOS2 3.
Metabolic Complications: Deficiencies may contribute to obesity, hyperandrogenism, and elevated cardiovascular risk factors4.

Therapeutic Benefits of Supplementation

Supplementing calcium and vitamin D may offer several benefits for women with PCOS:

Improved Menstrual Regularity: Studies suggest that supplementation can enhance menstrual cyclicity and ovulation1 2.
Enhanced Insulin Sensitivity: Vitamin D supplementation has been shown to improve insulin sensitivity, reducing the risk of metabolic complications3 6.
Weight Management: Calcium and vitamin D may aid in weight loss and body fat reduction, which are crucial for managing PCOS symptoms1.

Conclusion

Calcium and vitamin D deficiencies are prevalent among women with PCOS and may contribute to the severity of symptoms. While more research is needed to fully understand the therapeutic potential of supplementation, existing evidence suggests that addressing these deficiencies could improve menstrual regularity, insulin sensitivity, and overall metabolic health in women with PCOS.

Table: Summary of Calcium and Vitamin D Supplementation Effects on PCOS

Effect of Supplementation	Findings
Menstrual Regularity	Improved menstrual cyclicity and ovulation.
Insulin Sensitivity	Enhanced insulin sensitivity, reducing metabolic complications.
Weight Management	Aids in weight loss and body fat reduction.
Vitamin D Deficiency Correction	Corrects deficiency in a significant proportion of PCOS patients.
Metabolic Health	Reduces risk factors for cardiovascular diseases and type 2 diabetes.
