How do doctors diagnose fibroids?

When you first see your doctor
If your doctor thinks you might have fibroids, he or she will probably ask you about your symptoms and how they affect you. You may be asked about your periods and your sex life.

Your doctor may also want to feel your womb by putting a finger in your vagina and a hand on your lower belly. If you have fibroids, your womb may feel large and lumpy.

You may also need tests to check whether you have fibroids.

Blood test
If you've been having heavy periods, your doctor may want to do a blood test to make sure you're not
 
 
 
 
 
anemia
Anemia is when you have too few red blood cells. Anemia can make you get tired and breathless easily. It can also make you look pale. Anemia can be caused by a number of different things, including problems with your diet, blood loss and some diseases.
 
 
 
 
 
anemic. If you're anemic, you have too few
 
 
 
 
 
red blood cells
Red blood cells are the part of your blood that makes it red. Their main job is to carry oxygen from your heart and lungs out to the tissues of your body. Once these cells unload oxygen, they pick up carbon dioxide. They take carbon dioxide back to your lungs so you can breathe it out of your body.
 
 
 
 
 
red blood cells. You may look pale and get tired easily.

MRI scan
An
 
 
 
 
 
MRI scan
The magnetic resonance imaging (MRI) machine uses a magnetic field to create detailed pictures of the inside of the body. These pictures allow doctors to look at parts of the body in three-dimensional images.
 
 
 
 
 
MRI scan gives pictures of the inside of your body. In this case, it shows all the organs in your
 
 
 
 
 
pelvis
Your pelvis is the area between your hips.
 
 
 
 
 
pelvis, including your womb and any fibroids in it.

Ultrasound scan
An ultrasound scan uses sound waves to make a picture of the inside of your womb. There are two kinds of ultrasound scan:

  • A scan through your vagina (transvaginal ultrasound)
  • A scan through your abdomen.
The scan through your vagina is better for telling if you have fibroids.

Your doctor puts a
 
 
 
 
 
ultrasound probe
Ultrasound is a tool doctors use to create images of the inside of your body. An ultrasound machine sends out high-frequency sound waves, which are directed at an area of your body. The waves reflect off parts of your body to create a picture. Ultrasound is often used to see a developing baby inside a woman's womb.
 
 
 
 
 
probe into your vagina. It's shaped like a tiny flashlight with a round end. It sends out sound waves that bounce off the organs in your
 
 
 
 
 
pelvis

pelvis to give a picture.

Many women find out they have fibroids when they have routine ultrasound scans because they're pregnant. Doctors are less worried than they used to be about the effects of fibroids in pregnancy.

Other tests
You might find out you have fibroids when you have a test for another reason. For example, you may have a test called a laparoscopy to try to find out why you can't get pregnant. During this test, your doctor looks inside your pelvis with a tiny camera and a light. You'll be given a
 
 
 
 
 
general anesthetic
You may have a type of medication called a general anesthetic when you have surgery. It's given to make you unconscious so you don't feel pain.
 
 
 
 
 
general anesthetic, so you'll sleep through it. Your doctor puts the instruments through small cuts in your lower belly. He or she can see your womb and the other organs around it.

Another test is called a hysteroscopy. In this test, your doctor puts the camera and light into your womb through your vagina. You can have a general anesthetic or a
 
 
 
 
 
local anesthetic
Local anesthetic is a painkiller for one area of your body. You usually get it as a shot. It makes that area numb. An example is the novocaine you get when your dentist fills a cavity.
 
 
 
 
 
local anesthetic (shots to make you numb) so that this test won't hurt.
