Uterine fibroids are common, almost always non-cancerous growths of the uterine muscle. Many women have them with no symptoms; others get heavy periods, pelvic pressure or fertility concerns. They’re very manageable — with the right diagnosis and a plan matched to your symptoms, size and pregnancy plans, most women feel like themselves again.
What are uterine fibroids?
Uterine fibroids — also called leiomyomas or myomas — are benign growths of muscle and connective tissue in the wall of the uterus, and one of the most common gynaecological conditions. They’re most common between ages 30 and 50, affecting roughly 30–40% of women in that range. They vary widely in size, number and location, from seed-sized to large enough to distort the uterus. They aren’t life-threatening, but they can affect comfort, fertility and wellbeing — so understanding them helps you decide on care with confidence.
Types of fibroids
Fibroids are classified by where they sit, and position often matters more than size in deciding symptoms and treatment:
- Intramural fibroids — develop within the uterine wall; the most common type.
- Subserosal fibroids — grow on the outer wall and can press on nearby organs; often symptomless unless large.
- Submucosal fibroids — form inside the uterine cavity and are the type most likely to cause heavy bleeding and fertility problems.
- Pedunculated fibroids — grow on a stalk, inside or outside the uterus.
What causes fibroids?
The exact cause isn’t fully understood, but several factors contribute:
- Hormones — estrogen (and progesterone) stimulate growth, which is why fibroids often shrink after menopause.
- Genetics — a family history increases your risk, and changes in uterine muscle cells may trigger growth.
- Lifestyle and diet — obesity and higher estrogen are linked to fibroids, and a diet high in red and processed meat may raise the risk.
- Inflammation and environment — chronic inflammation and hormone-disrupting chemicals (certain plastics, pesticides) may play a role.
- Vitamin D deficiency — research links low vitamin D to higher risk; discuss any supplement with your doctor.
Symptoms to look out for
Many women have no symptoms. When they occur, they fall into three groups:
- Menstrual & reproductive — heavy or prolonged periods (menorrhagia), which can cause anaemia (fatigue, dizziness, weakness); severe cramps; bleeding between periods; and sometimes difficulty conceiving or repeated miscarriage.
- Pelvic pain & pressure — lower-abdominal fullness or discomfort, pain during intercourse (dyspareunia), and frequent urination if a fibroid presses on the bladder.
- Digestive & bowel — constipation or bloating if a fibroid presses on the rectum, and lower-back or leg pain if it presses on pelvic nerves. If any of these affect daily life, get checked — early care protects your comfort and fertility.
How fibroids are diagnosed
To confirm the presence, size and location of fibroids, your doctor may use a pelvic examination (to check for an enlarged or irregular uterus), an ultrasound (the most common, non-invasive scan), an MRI (a detailed view, especially before surgery), and a hysteroscopy (a slim camera passed into the uterus to check for submucosal fibroids inside the cavity).
Treatment options
Treatment depends on the size and location of the fibroids and the symptoms they cause — and on whether you wish to conceive.
- Medication (non-surgical). For younger women with small fibroids, birth-control pills, progestins, GnRH-agonist injections or mifepristone can regulate bleeding and shrink fibroids. Hormonal treatments (pills or a hormone-releasing IUD) control heavy bleeding, GnRH agonists shrink fibroids by lowering estrogen, and NSAIDs relieve cramps but don’t shrink fibroids.
- Minimally invasive procedures. Uterine Fibroid Embolisation (UFE) blocks the blood supply so fibroids shrink, and MRI-guided Focused Ultrasound (FUS) uses high-energy sound waves to destroy fibroid tissue.
- Surgery. Myomectomy removes the fibroid while preserving the uterus — the preferred choice for women who wish to conceive — done by laparoscopy (keyhole), hysteroscopy, or open surgery. Hysterectomy (removing the uterus) is an option for severe, recurrent symptoms when childbearing is complete. Uterine artery embolisation cuts off the blood supply but can cause significant pain afterwards and isn’t suitable if you’re planning pregnancy.
Surgery is usually advised when medication fails to control bleeding; a fibroid is larger than about 4 cm and pressing on organs; fibroids cause infertility or recurrent miscarriage; or a fibroid grows after menopause (surgery is then recommended to rule out any rare malignancy). As a laparoscopic and endoscopic surgeon, Dr. Richa Gangwar favours the most conservative, uterus-preserving approach appropriate to each case — see laparoscopic & endoscopic surgeries.
Fibroids, fertility & pregnancy
A diagnosis when you’re planning a family can feel worrying, but many women with fibroids conceive naturally and have healthy pregnancies — the impact depends on size, number and location. Before pregnancy, small fibroids that don’t affect the lining or tubes usually don’t hinder fertility, while larger or submucosal fibroids can interfere with implantation or block the tubes; these can be treated first with medication to shrink them or a laparoscopic/hysteroscopic myomectomy that preserves the uterus. During pregnancy, most fibroids cause no serious problems, but some may cause pain as the uterus expands, a higher risk of miscarriage or preterm labour, placental issues, malpresentation, or occasionally obstructed labour needing a C-section — risks usually well managed with trimester-wise scans, pregnancy-safe pain relief and delivery planning. If you’re already pregnant with fibroids, don’t panic — regular monitoring is usually all that’s needed.
Diet, lifestyle & living with fibroids
Diet won’t cure or shrink fibroids, but a fibre-rich diet, a healthy weight and regular activity support hormone balance and wellbeing — see how diet & lifestyle affect fibroid growth. Many small or symptom-free fibroids simply need periodic monitoring rather than treatment. And if you live with ongoing pelvic pain or heavy periods, you don’t have to accept it as “just part of being a woman” — effective pain management and treatment are available.
When to see a doctor
Seek advice for excessive bleeding that affects daily life, severe pelvic pain or swelling, difficulty getting pregnant, or rapidly growing fibroids causing pressure — and always for any bleeding after menopause. Early diagnosis and a plan tailored to you make fibroids very manageable.

FAQ:-
Are uterine fibroids cancerous?
No — the overwhelming majority are benign. A cancerous tumour of the uterine muscle (leiomyosarcoma) is rare. New growth or bleeding after menopause should always be checked.
Can you get pregnant with fibroids?
Yes. Many women with fibroids conceive naturally. Small fibroids usually don’t affect fertility; larger or submucosal ones may, and can be treated before conception.
What size of fibroid needs surgery?
Often when larger than about 4 cm and pressing on organs, when bleeding can’t be controlled with medication, or when fibroids affect fertility.
Do fibroids go away on their own?
They often shrink after menopause. Before menopause they’re managed; small, symptom-free fibroids may simply be monitored.
What foods should I avoid with fibroids?
There’s no proven “anti-fibroid” diet, but limiting red and processed meat, refined sugar and excess alcohol, and eating more fibre while keeping a healthy weight, supports hormone balance.
