Fibroids are very common and affect 40–50% of women over 35. They usually shrink after menopause and new fibroids rarely appear, but fibroids that persist may still be found after menopause.

Grows deep inside the muscle wall of the uterus. It enlarges the uterus and the area of the uterine lining, which makes periods heavier.
Grows just under the outer layer covering the uterus. It can hang down and form a stalk.
Causes many complications. Even a small one can cause bleeding. It has a higher risk of sarcomatous change, is prone to infection, pus formation and tissue death, and does not respond well to radiation.

If someone in your family has fibroids, your risk may be higher.
Persistently high levels of the female hormone estrogen are involved in fibroid growth and can lead to fibroids.
A Western-style diet high in fat can raise estrogen levels in the body and may lead to fibroids.
A lot of stress can make periods irregular and harm the health of the uterus.

Many women with fibroids have no symptoms. But about 30–35% of women with fibroids have symptoms, which can vary. Depending on the size, number and location of the fibroids, there may be one symptom or several.
How bloated you feel depends largely on the size and location of the fibroid.
It may also cause back pain. As the fibroid grows it presses on organs around the pelvis, causing bloating, difficulty urinating and constipation.
Heavier periods are common in women with fibroids.
Heavier bleeding and longer, more painful periods are known to be period problems caused by fibroids. Abnormal bleeding is also a common symptom, and any type of fibroid can cause bleeding.
Submucosal fibroids in particular bleed more easily because of surface infection and ulceration, so it is best to have a specialist check-up.
A fibroid in the uterine muscle can disrupt its normal contraction and relaxation, causing period pain you didn't have before or making period pain worse.
