Fibroids

Fibroids are non-cancerous growths that develop in or around the womb (uterus).

The growths are made up of muscle and fibrous tissue and vary in size. They’re sometimes known as uterine myomas or leiomyomas.

Many women are unaware they have fibroids because they don’t have any symptoms. Women who do have symptoms (around one in three) may experience:

Heavy periods or painful periods
Tummy (abdominal) pain
Lower Back Pain
A frequent need to urinate
Constipation
Pain or discomfort during sex

In rare cases, further Complications Caused By Fibroids can affect pregnancy or cause Infertility.

Seeing Your Doctor

As fibroids don’t often cause symptoms, they’re sometimes diagnosed by chance during a routine gynaecological examination, test or scan.

However, see your doctor if you have persistent symptoms of fibroids so they can investigate possible causes.

If your doctor thinks you may have fibroids, they’ll usually refer you for an ultrasound scan to confirm the diagnosis. Read More About: Diagnosing Fibroids.

Why Fibroids Develop

The exact cause of fibroids is unknown. However, they’re linked to the hormone oestrogen. Oestrogen is the female reproductive hormone produced by the ovaries (the female reproductive organs).

Fibroids usually develop during a woman’s reproductive years (from around 16 to 50 years of age) when oestrogen levels are at their highest. They tend to shrink when oestrogen levels are low, such as after the Menopause (when a woman’s monthly periods stop).

Who Gets Fibroids?

Fibroids are common, with around 1 in 3 women developing them at some point in their life. They most often occur in women aged 30-50.

Fibroids are thought to develop more frequently in women of African- Caribbean origin. It’s also thought they occur more often in overweight or obese women because being overweight increases the level of oestrogen in the body.

Women who’ve had children have a lower risk of developing fibroids, and the risk decreases further the more children you have.

Types of Fibroids

Fibroids can grow anywhere in the womb and vary in size considerably. Some can be the size of a pea, whereas others can be the size of a melon.

The main types of fibroids are:

Intramural fibroids – the most common type of fibroid, which develop in the muscle wall of the womb
Subserosal fibroids – fibroids that develop outside the wall of the womb into the pelvis and can become very large
Submucosal fibroids – fibroids that develop in the muscle layer beneath the womb’s inner lining and grow into the cavity of the womb

In some cases, subserosal or submucosal fibroids are attached to the womb with a narrow stalk of tissue. These are known as pedunculated fibroids.

Treating Fibroids

Treatment for fibroids isn’t needed if they aren’t causing symptoms. Over time, fibroids will often shrink and disappear without treatment, particularly after the menopause.

If you do have symptoms caused by fibroids, medication to help relieve the symptoms will usually be recommended first.

There are also medications available to help shrink fibroids. If these prove ineffective, surgery or other less invasive procedures may be recommended. Read More About: Treating Fibroids.
