Treatment may not be necessary in cases where there are no symptoms of fibroids, or where symptoms are minor and your everyday activities are not significantly affected.
After the menopause, fibroids often shrink, and it is likely your symptoms will either ease slightly or disappear completely.
For example, if you have heavy periods already, you may choose not to have treatment because your day-to-day life is not significantly affected.
If you have fibroids that need treatment, your GP may recommend medication to help relieve your symptoms. However, you may need to see a gynaecologist (specialist in the female reproductive system) for further medication or surgery if these are ineffective.
You should visit your GP to discuss the best treatment plan for you.
Medication for symptoms
There are medicines available that can be used to reduce heavy periods, but they can be less effective the larger your fibroids are. These medications are described below.
Levonorgestrel intrauterine system (LNG-IUS)
LNG-IUS is a small, plastic device placed in your womb and slowly releases the progestogen hormone called levonorgestrel. LNG-IUS stops the lining of your womb from growing quickly, so that it is thinner and your bleeding becomes lighter.
Side effects associated with LNG-IUS include:
- irregular bleeding that may last for more than six months
- acne (inflamed skin on the face)
- breast tenderness
- in rare cases, LNG-IUS may also stop you having periods at all (absent periods)
LNG-IUS also acts as a contraceptive, but does not affect your chances of getting pregnant after you stop using it.
If LNG-IUS is unsuitable (for example, if contraception is not desired), tranexamic acid tablets may be considered. These tablets work by helping the blood in your womb to clot.
Tranexamic acid tablets are taken three times a day throughout your period for up to four days. Treatment should be stopped if your symptoms have not improved within three months.
Tranexamic acid tablets are not a form of contraception and will not affect your chances of becoming pregnant once you stop taking them.
Possible side effects include indigestion and diarrhoea.
Non-steroidal anti-inflammatory medicines (NSAIDs), such as ibuprofen and mefenamic acid, can be taken three or four times a day from the first day of your period until bleeding stops or reduces to satisfactory levels.
They work by reducing your body’s production of a hormone-like substance called prostaglandin, which is linked to heavy periods.
Anti-inflammatory medicines are also painkillers, but are not a form of contraception.
Indigestion and diarrhoea are common side effects.
The contraceptive pill
The contraceptive pill is a popular form of contraception that stops an egg from being released from the ovaries to prevent pregnancy.
As well as making bleeding lighter, some contraceptive pills can help to reduce period pain.
Your GP can provide you with further advice about contraception and the contraceptive pill.
Norethisterone is a type of man-made progestogen (one of the female sex hormones) that can help reduce heavy periods. It is usually taken as a daily tablet from days 5 to 26 of your menstrual cycle, counting the first day of your period as day one.
Oral norethisterone works by preventing your womb lining growing quickly. It is not a form of contraception, although it can reduce your chances of conceiving while you are taking it.
The side effects of oral norethisterone can be unpleasant, and include weight gain, breast tenderness and short-term acne.
Progestogen is also available as an injection to treat heavy periods. This medication works by preventing the lining of your womb growing quickly.
This form of progestogen can be injected once every 12 weeks for as long as treatment is required.
Common side effects of injected progestogen include:
- weight gain
- irregular bleeding
- absent periods
- premenstrual symptoms, such as bloating, fluid retention and breast tenderness
Injected progesterone also acts as a contraceptive. It does not prevent you becoming pregnant after you stop using it, although there may be a delay after you stop taking it before you are able to get pregnant.
Medication to shrink fibroids
Gonadotropin releasing hormone analogues (GnRHas)
If you are still experiencing symptoms related to fibroids despite treatment with the medications outlined above, your GP can refer you to a gynaecologist. They may prescribe medication called gonadotropin releasing hormone analogues (GnRHas) to help shrink your fibroids.
GnRHas such as goserelin acetate, are hormones given by injection and work by making your body release a small amount of the hormone oestrogen, which causes your fibroids to shrink.
GnRHas stop your menstrual cycle (period), but they are not a form of contraception. They do not affect your chances of becoming pregnant after you stop using them.
If you are prescribed GnRHas, they can help to ease heavy periods and any pressure that is felt on your stomach. They can also help to improve symptoms of frequent urination and constipation.
Sometimes GnRHas are used to shrink fibroids prior to having surgery to remove them.
GnRHas can cause a number of menopause-like side effects including:
- hot flushes
- increased sweating
- muscle stiffness
- vaginal dryness
Sometimes a combination of GnRHas and low doses of hormone replacement therapy (HRT) may be recommended to shrink your fibroids, while preventing the side effects of the menopause.
Osteoporosis (thinning of the bones) is an occasional side effect of taking GnRHas. Your GP will be able to give you more information about this, and may prescribe additional medication to minimise thinning of your bones.
GnRHas are only prescribed on a short-term basis (a maximum of six months at a time). Your fibroids may grow back to their original size after treatment is stopped.
Surgery may be considered if your fibroid symptoms are particularly severe and all forms of medication have proved ineffective.
There are several different surgical procedures used to treat fibroids. Your GP will refer you to a specialist who will be able to discuss all the options with you, including the benefits and any associated risks.
Some of these surgical procedures are explained below.
A hysterectomy is a surgical procedure to remove the womb. It is the best way of preventing fibroids from coming back.
It may be recommended if you have large fibroids or severe bleeding and you do not wish to have any more children.
There are a number of different ways a hysterectomy can be carried out, including through the vagina or through a number of small incisions in your abdomen (tummy).
Depending on the technique used, the procedure can be carried out under local anaesthetic (where you will be numbed from the waist down) or general anaesthetic (where you are unconscious during the procedure).
You will usually need to stay in hospital for a few days after a hysterectomy. It takes about six to eight weeks to fully recover, during which time you should rest as much as possible.
Side effects of a hysterectomy include the possibility of early menopause and a reduction in libido (sex drive).
A myomectomy is a surgical procedure to remove the fibroids from the wall of your womb. It may be considered as an alternative to a hysterectomy, particularly for women who still wish to have children.
However, a myomectomy is not suitable for every type of fibroid. Your gynaecologist will be able to tell you if the operation is suitable for you based on things such as the size, number and position of your fibroids.
Depending on the size and position of the fibroids, a myomectomy may involve making either a number of small incisions (cuts) in your tummy (keyhole surgery) or a single larger incision (open surgery).
Myomectomies are carried out under general anaesthetic and you usually need to stay in hospital for a few days after the procedure. Like a hysterectomy, you will normally be advised to rest for several weeks while you recover.
Myomectomies are generally an effective treatment for fibroids, although there is a chance the fibroids will grow back and further surgery will be needed.
As well as traditional surgical techniques to treat fibroids, there are also non-surgical treatments available. These are outlined below.
Uterine artery embolisation (UAE)
Uterine artery embolisation (UAE) is an alternative procedure to a hysterectomy or myomectomy for treating fibroids. It may be recommended for women with large fibroids.
UAE is performed by a radiologist (who specialises in interpreting X-rays and scans). It works by blocking the blood vessels that supply blood to the fibroids, causing them to shrink.
During the procedure, a chemical is injected through a small tube (catheter), which is guided by X-ray through a blood vessel in your leg. It is carried out under local anaesthetic, which means you will be awake but the area being treated will be numbed.
Following a UAE, you will need to stay in hospital for 24 to 36 hours. When you leave hospital, you will be advised to rest for one to two weeks.
The effect of having the procedure on any future pregnancies is unknown, so it is not recommended that you try to get pregnant afterwards.
Endometrial ablation is a relatively minor procedure that involves removing the lining of the womb. It is mainly used to reduce heavy bleeding in women with fibroids, but it can also be used to treat small fibroids in the womb lining.
The affected womb lining can be removed in a number of ways, for example by using laser energy, a heated wire loop, microwave heating or hot fluid in a balloon.
The procedure can be carried out under local or general anaesthetic. It is fairly quick to perform, taking around 20 minutes, and you can often go home the same day.
You may experience some vaginal bleeding and tummy cramps for a few days afterwards, although some women have bloody discharge for three or four weeks.
While it may still be possible to get pregnant after having endometrial ablation, the procedure is not recommended for women who wish to have more children. This is because the risk of serious problems, such as miscarriage, is high.
Hysteroscopic resection of fibroids is a procedure that involves using a thin telescope called a hysteroscope and a number of small surgical instruments to remove fibroids. The procedure is carried out through the vagina, so no incisions are needed.
The procedure can be used to remove small fibroids located inside the womb (submucosal fibroids) and is suitable for women who wish to have children in the future.
Hysteroscopic resection of fibroids is often performed under a general anaesthetic, although local anaesthetic may also be used. You can usually go home the same day the procedure is carried out.
You may experience stomach cramps after the procedure, but these should only last a few hours. There may also be a small amount of vaginal bleeding, which should stop within a few weeks.
There are also two newer techniques for treating fibroids, which use magnetic resonance imaging (MRI). They are:
- MRI-guided percutaneous laser ablation
- MRI-guided transcutaneous focused ultrasound
These techniques use MRI to guide small needles into the centre of the fibroid being targeted. Laser energy, or ultrasound energy is then passed through the needles to destroy the fibroid.
These treatment methods cannot be used to treat all types of fibroids, and the long-term benefits and risks are unknown. As these procedures are relatively new, they are not yet widely available in the UK.
Although research is still being done, some evidence suggests that this non-invasive procedure has short- to medium-term benefits when performed by an experienced clinician.
However, the effects on pregnancy and those wishing to have a baby in the future are not fully known, so this should be taken into consideration.
