Study identifies a potential 25% increase in hearing loss risk associated with hormone replacement therapy, as revealed in research involving 200,000 women.

In a recent study, academics at Shandong University in China have provided evidence that hormonal imbalance could contribute to age-related hearing loss in women during menopause. The findings, published in the medical journal Maturitas, suggest that the use of menopausal hormone therapy (HRT) in women who underwent natural menopause at typical ages (46 to 55) was associated with an increased risk of hearing loss.

The study with perimenopausal mice adds to the growing body of evidence linking hormone replacement therapy to an increased risk of hearing loss in menopausal women. Previous research has also shown that oestrogen plus progestin could potentially accelerate age-related hearing loss in perimenopausal mice.

HRT replenishes the female sex hormones oestrogen and progesterone lost during menopause, helping to counter symptoms such as hot flushes, night sweats, anxiety, mood swings, and osteoporosis. However, the exact mechanism by which hormone replacement therapy contributes to hearing loss in menopausal women remains unclear.

Scientists are still researching the relationship between hormone therapy and hearing loss in menopausal women. One theory suggests that hormone levels might affect bone density, which could impair middle ear transmission. Another theory points to the presence of oestrogen receptors in the ear's auditory system, but little is known about how they function.

A study based on over 200,000 women in the UK found that menopausal women using HRT had a 25% higher risk of losing their hearing compared to non-users. However, no significant association was observed in women with premature or late menopause. It is important to note that the risk of hearing damage from HRT increases with the length of usage.

The study's findings are in line with high-profile campaigns by celebrities like Davina McCall and Mariella Frostrup, which have led to a significant rise in the use of hormone therapy over the past five years. Despite this, more research is needed to understand the underlying mechanisms linking hormone replacement therapy and hearing loss in menopausal women.

As the research continues, women considering hormone replacement therapy should discuss the potential risks and benefits with their healthcare provider. The authors of the study investigating the relationship between hormone replacement therapy and increased risk of hearing loss in menopausal women and the journal in which the results were published are not provided in the available search results.
