Fibroids
Uterine fibroids are benign growths that form in or on the wall of your uterus (womb). They can cause heavy bleeding during periods, pain, and other symptoms.
What are fibroids?
Fibroids are non-cancerous (benign) tumours that form in or around the uterus (womb). These growths are made up of muscle and fibrous tissue, can vary in size, and develop in different areas of the womb. They’re usually rounded and look like smooth bumps, although sometimes they can be attached with a thin stem.
Fibroids are very common – up to 40% of women in the UK are thought to have one or more of these growths – but not all fibroids cause symptoms, which means many women don’t know they have them.
Our women’s health specialists see patients with fibroids in our purpose-built Women’s Health centre, where they offer the most advanced care in both diagnostics and treatment.
More information
Fibroids come in all different shapes and sizes. Most small fibroids don’t cause any symptoms and won’t need treatment.
But larger fibroids can bring on many uncomfortable symptoms, such as:
very heavy or painful bleeding during your period
bleeding between your periods
bloating, or a feeling of fullness in your lower tummy
needing to pee more often
pain during sex
lower back pain
constipation, or a feeling of pressure on your rectum
long-term vaginal discharge
feeling like you can’t fully empty your bladder
Fibroids can be split into 4 main categories, depending on where they’re found. These include:
submucosal fibroids – fibroids that grow under the lining of your uterus. They often cause heavy periods, and may lead to miscarriage or difficulty getting pregnant
intramural fibroids – the most common type of fibroid that are deep in the muscular wall of the womb and tend to cause heavy bleeding or pressure symptoms
subserosal and serosal fibroids – fibroids that grow under the lining of the outer surface of your uterus. They can grow quite large, and are most likely to cause pressure symptoms
pedunculated fibroids – fibroids that are attached to the surface of the womb by a stalk and can cause pain (if they twist on their stalk) and/or pressure symptoms. These are less common
Why fibroids develop in some women but not others isn’t fully understood, but it’s thought that the hormones oestrogen and progesterone may play a role.
Most fibroids happen in people of reproductive age and tend to grow when hormone levels are higher (like during pregnancy) and shrink when hormone levels are low, like during the transition to menopause.
Any woman of reproductive age can develop fibroids, but you may be more at risk if you:
are obese or have a high body mass index (BMI)
have a family history of fibroids
drink a lot of alcohol – especially beer
eat a lot of red meat and not enough green vegetables
have African-Caribbean heritage – black women are more likely to have fibroids than people of other racial groups. They may also have larger fibroids and worse symptoms
haven’t had children
started your period at a young age – before the age of 10
went through menopause at a late age
Fibroids can be diagnosed by a specialist during an ultrasound scan. In some cases, an MRI scan will be needed to give more information about the number, location, and size of the fibroids, to help work out the best treatment.
It’s not possible to completely avoid fibroids, but you may be able to reduce your risk by:
maintaining a healthy weight
getting regular pelvic exams
eating a balanced diet
Most fibroids won’t cause any serious problems. But sometimes they can lead to complications, such as:
pain that stops you from going about life as normal
swelling of your tummy or pelvic area
very heavy bleeding
anaemia, due to heavy blood loss
infertility, but this is rare
Treatment options can vary depending on the size, number, and location of the fibroids, as well as your symptoms.
Small fibroids can often be monitored occasionally by ultrasound or pelvic exam.
If your fibroids are causing heavy periods or other symptoms, treatment options may include:
the contraceptive pill – it can help with heavy bleeding between and during your period
tranexamic acid – a medicine to reduce heavy bleeding
iron supplements – if heavy blood loss has caused anaemia
gonadotropin-releasing hormone (GnRH) agonists – medicines used to shrink fibroids temporarily. They’re often used before surgery
surgery – performed if your fibroids are very large, other treatments haven’t helped, or they’re causing severe symptoms.

Frequently asked questions
Fibroids can cause different types of pain, depending on where they’re found and how big they are. Small fibroids may not cause any symptoms at all, while larger fibroids can lead to back pain, stabbing pains in your tummy, and even pain during sex.
Most women are able to get pregnant with fibroids. But during pregnancy, the body releases higher levels of hormones, which can cause fibroids to get bigger. If they become larger during this time, it may increase your risk of needing a C-section and/or having a premature birth.
Fibroids range in size from smaller than a pea to as large as a watermelon. Most fibroids are quite small and don’t cause any symptoms, but larger ones can lead to heavy bleeding, pelvic pain, and other uncomfortable symptoms.
Fibroids tend to shrink in some people after they’ve gone through menopause because of a drop in hormone levels. If this happens, symptoms may settle on their own.
