Can perimenopause worsen hypothyroidism symptoms?

Question

Hello doctor,

I am a 42-year-old woman and have been managing hypothyroidism for the past five years. Recently, I have noticed weight gain, hair loss, and feelings of depression. My menstrual cycles have also become heavier and more irregular.

Could these symptoms be a combination of perimenopause and thyroid dysfunction? How are thyroid issues typically managed in women during midlife, and do they have any impact on bone health or fertility? Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Based on your presentation, it appears you may be experiencing a combination of hypothyroidism (an underactive thyroid gland leading to slowed metabolism) and perimenopausal changes (the transitional phase before menopause marked by hormonal fluctuations). Both conditions can impact fertility and contribute to bone health deterioration as menopause approaches.

Clinical assessment:

According to the International Federation of Gynecology and Obstetrics (FIGO) classification of abnormal uterine bleeding:

Frequency: A normal menstrual cycle occurs every 24 to 38 days. A cycle longer than 38 days is considered infrequent.
Duration: Menstrual bleeding should last no more than eight days.
Regularity: A variation of less than nine days between your shortest and longest cycles is considered regular. Flow volume: The menstrual flow should be within a normal range and not excessively heavy.
Your reported symptoms, irregular, heavy periods, and mood changes, are consistent with hormonal imbalances due to thyroid dysfunction and perimenopause.

Diagnostic workup:

To confirm the diagnosis and identify the exact cause, the following investigations are recommended:

Serum thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) (to assess thyroid function).
Serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH) (to evaluate ovarian reserve and menopausal status).
Pelvic ultrasound (to detect any abnormalities in the uterus or ovaries, such as fibroids or cysts).

Management plan

You are advised to consult a consultant endocrinologist for expert guidance on hormonal and thyroid management. Meanwhile, the following medications may be started under medical supervision:

Tablet Thyroxine 50 micrograms (mcg) – Take once daily in the morning on an empty stomach (for thyroid hormone replacement).
Tablet Norethisterone 5 milligrams (mg) – Take three times daily for three months (to control irregular and heavy menstrual bleeding).
Tablet Cholecalciferol (vitamin D3) – To support bone health and reduce the risk of osteoporosis (a condition causing brittle bones).
