What causes light periods and hair loss in a woman aged 29?

Hello,

Welcome to icliniq.com.

I can understand your concern.

Hypomenorrhea (light periods) and hair loss. Your day two hormonal results show a slightly elevated follicle-stimulating hormone (FSH) level of 13 IU/L, which may suggest diminished ovarian reserve. Luteinizing hormone (LH), prolactin, and thyroid-stimulating hormone (TSH) are within normal ranges, though TSH is on the higher side, which could point to subclinical hypothyroidism.

Your estrogen level is slightly elevated, possibly due to the timing of the test or lab variation. Given your low body weight, these findings suggest the possibility of functional hypothalamic amenorrhea or early ovarian insufficiency, which may be influenced by undernutrition, chronic stress, subclinical thyroid issues, or early signs of reduced ovarian reserve.

To investigate further, recommended tests include Anti-Müllerian Hormone (AMH) to assess ovarian reserve, Free T3 and Free T4 for detailed thyroid evaluation, ferritin, vitamin D, and B12 for nutritional assessment, and androgen levels to rule out polycystic ovary syndrome (PCOS).

A pelvic ultrasound to evaluate the antral follicle count and uterine lining would also be helpful. In the meantime, it is important to track your menstrual cycles and symptoms monthly, ensure a balanced and calorie-sufficient diet, avoid over-exercising or prolonged fasting, and consider nutritional support like biotin, zinc, and iron-rich foods to help with hair health.

You should see a doctor if your periods become lighter or stop, if hair loss worsens or becomes patchy, or if test results suggest reduced ovarian reserve.

I hope this helps.

Thank you.
