How fast do fibroids shrink after menopause?

Uterine fibroids are non-cancerous growths which can develop in or around the uterus. They can cause symptoms such as heavy bleeding, pain, or pressure. Many women wonder what happens to fibroids after menopause. Let's break it down in simple terms.

What are fibroids?

Fibroids are lumps of muscle and tissue that grow in the uterus. They can be different sizes—some are tiny, while others can be quite large. They often develop due to hormones, particularly oestrogen and progesterone. This means that when hormone levels change, fibroids change too.

How do fibroids change after menopause?

Menopause is when a woman's periods stop permanently, usually around the age of 45-55. During menopause, the body stops producing as much oestrogen and progesterone, which causes fibroids to shrink. This is because fibroids need those hormones to grow.

How fast do they shrink?

The process of fibroids shrinking is not instant. Here’s what usually happens:

• First six months: Fibroids may start to get smaller, but the change is usually slow.
• Six to 12 months: Many women start to notice a bigger difference in size and fewer symptoms.
• 1 to 3 years: The fibroids keep shrinking, and symptoms like heavy bleeding or pain often improve or even go away.

Overall, fibroids can shrink by 30-50 per cent in size after menopause. For some women, they might shrink even more, while for others, the change is less noticeable.

Why do fibroids shrink?

When oestrogen levels drop during menopause, fibroids lose their main fuel for growth. Without these hormones, fibroid cells break down, and blood flow to the fibroids decreases. This makes them shrink over time.

Factors that affect shrinkage

The speed at which fibroids shrink depends on several things:

• Fibroid size: Bigger fibroids take longer to shrink compared to smaller ones.
• Hormone levels: If someone still has higher hormone levels after menopause, their fibroids might shrink more slowly.
• Hormone replacement therapy (HRT): Some women take hormones during menopause to help with symptoms like hot flashes. If they use HRT, especially with oestrogen, fibroids may not shrink as much and could even grow.

Symptoms after menopause

As fibroids shrink, many symptoms improve. For example:

• Heavy bleeding: After menopause, periods stop, which means heavy bleeding caused by fibroids usually stops too.
• Pelvic pain and pressure: As the fibroids get smaller, they press less on surrounding organs, which often reduces pain and discomfort.

When fibroids don’t shrink

In some cases, fibroids might not shrink after menopause. This can happen if:

• oestrogen levels remain: The body still produces small amounts of oestrogen even after menopause, which can keep the fibroids from shrinking;
• hormone therapy: Women using HRT with oestrogen might find that their fibroids stay the same size or even grow.

If fibroids don’t shrink and continue to cause problems, doctors may suggest treatments to help manage symptoms. This could include medications or, in some cases, surgery.

Should you be concerned about fibroids after menopause?

In most cases, fibroids become less of a problem after menopause. However, if you have symptoms like vaginal bleeding after menopause or new pelvic pain, it’s important to see a doctor. This is because these symptoms could be a sign of other health issues.

Conclusion

Fibroids usually shrink after menopause because the body stops making the hormones they need to grow. The process takes time, often several months to a few years, but for many women, this means symptoms get much better. If fibroids continue to cause problems, there are treatments that can help.

If you are dealing with fibroids or worried about their effects during menopause, it’s a good idea to talk to your doctor. They can help you figure out the best way to manage your symptoms and improve your quality of life.
