Fibroids And Pregnancy – 8 Things You Need To Know

Fibroids And Pregnancy – 8 Things You Need To Know

Many women of childbearing age are diagnosed with gynecological concerns such as fibroids, PCOS and endometriosis.

These frustrating issues take on a whole new level when you discover you’re pregnant.

If you’ve been told you have fibroids, you may wonder how they may impact your pregnancy.

Will you experience a high risk pregnancy?

Will fibroids put you and your baby at risk for serious complications?

For some women, fibroids have little to no impact on their daily life, fertility or pregnancy.

But for others, fibroids can have a major impact.

Fibroids and Pregnancy

Here are 8 things you need to know about fibroids and pregnancy:

#1: Fibroids Are Common

Fibroids are non-cancerous masses of compacted muscle and fibrous tissue, found inside or outside the uterine wall.

A fibroid tumor may also be referred to as a leiomyoma or myoma.

With as many as 50-80% of women having fibroids, the condition is actually quite common.

#2: Fibroids Can Vary In Size

Some fibroids are as small as a pea, while others can be as large or larger than a grapefruit.

While most fibroids wont grow in size, around one third may grow in the first trimester of pregnancy. Fibroids which grow during pregnancy are the most problematic, as they can result in miscarriage.

Given the varying sizes and number of fibroids, symptoms can vary greatly from woman to woman. The location of the fibroid(s) can have an impact too.

#3: Fibroids Can Be Asymptomatic Or Be Problematic

Women with fibroids may have no noticeable symptoms, before, during or after pregnancy.

For other women, their fibroids come with such symptoms such as:

  • Abdominal Pain
  • Frequent urination, or urge to urinate
  • Heavy vaginal bleeding
  • Pelvic pressure and pain
  • Constipation

It’s important to contact your healthcare provider any time you have vaginal bleeding or pain, as they can also be symptoms of other concerns.

Reproductive and women’s health specialist, Doctor Andrew Orr, recommends women have fibroids removed prior to pregnancy if possible, in order to reduce the chances of miscarriage. Fibroids can result in ectopic pregnancy, and if a fibroid grows, it can harm a foetus, even causing a miscarriage.

#4: You May Not Need Treatment – But You Do Need To Consult A Specialist

For most women, fibroids don’t require any treatment. For some women, fibroids are surgically removed, either prior to or after pregnancy. This is especially the case for women with large fibroids which cause pain, heavy bleeding or if the fibroids are impacting fertility (e.g. the fibroid is blocking fallopian tubes).

You aren’t able to have uterine surgery to remove fibroids during pregnancy, so if you’re experiencing pain due to the fibroids, your healthcare provider will likely recommend a treatment plan and pain medication which is safe during pregnancy.

Doctor Orr says that during pregnancy, it’s more a case of treat, monitor and see. “It really depends where the fibroids are located — intrauterine [inside the uterus] fibroids are the biggest concern. Therefore, it’s important for pregnant women with fibroids to consult a specialist to assess their unique situation, and not try to self treat.”

#5: Complications Are Possible, But Not A Guarantee

For women with smaller fibroids that don’t grow, there’s little — if any — expected risk during pregnancy. Even for women with large fibroids, they can be low risk, but the size and location of the fibroids is the issue.

Depending on the size and location of the fibroids, there is an increased risk of miscarriage, in-uterine growth restriction, preterm birth, breech position, c-section, heavy postpartum bleeding or even hysterectomy.

#6: Fibroids Can Change During Pregnancy

Doctors aren’t certain why, but pregnancy hormones may cause your fibroids to grow or shrink. Your maternity care provider may monitor your fibroids to see if their changes increase your risk of complications.

If a fibroid is located near the bottom of the uterus, close to the cervix, growth could block the baby’s passage into the birth canal. If your midwife or doctor has any concerns, they will monitor you and make birth recommendations accordingly.

#7: Uterine Fibroids Don’t Automatically Mean A C-Section

While there is an increased risk of needing a c-section, many women with fibroids are able to have uncomplicated vaginal births. Unless the size and location of your fibroids is blocking the cervix, or the size and location impact baby’s ability to move into the optimal position, an uncomplicated vaginal birth is likely.

As fibroids change in size and as the uterus grows, even if a fibroid appeared to be a concern in early pregnancy, monitoring might show as the pregnancy continues, it becomes less of a concern.

If your healthcare provider recommends a c-section during early pregnancy, it’s a good idea to ask for monitoring towards the end of your pregnancy, so you can make an informed decision before scheduling it. Your situation may change and surgery may longer be needed.

#8: There Are No Miracle Cures

The internet is full of miracle cures for everything; however when it comes to fibroids, you should never self treat or consult doctor Google, because there are no miracle cures.

All you can do is leave the medical needs to your healthcare provider, and continue to be vigilant about your diet.

“Diet can be a factor with fibroids, because high insulin levels cause high estrogen levels, and that’s what the fibroids grow from – a high estrogen environment. So adopt a low GI diet all the way, as soon as possible in your conception journey. There are other things you can do to help during pregnancy, but this would require a professional consultation,” says Doctor Orr.

Healthy eating is very important during conception and pregnancy – science has discovered what we eat impacts the health of our unborn children, and not just ourselves.

By eating a healthy diet, eliminating sugar and processed grains (bread, cereals, pasta, processed foods), you can not only help to prevent and minimise problems associated with fibroids, but other pregnancy complications like gestational diabetes.

Pregnancy is a time of excitement, but also a time where common concerns can become worrisome. Fortunately, for most women, fibroid tumors are unlikely to cause complications during their pregnancy and birth.

  1. Hie, i am 25 years old and i am carrying now 4 concern is the 8 by 10 cm fibroid (myoma) i have.i have been experiencing lots of pain in the first three months but atleast now am first i was afraid of having a miscarriage but now am comfortable upon reading your article. the only question i have are,since my fibroid still grows ( examined by a gynaecologist),is there any danger to my baby? Am i going not to lose the pregnancy? What about the growth of my unborn baby and lastly,do i have to expect more pains throughout the pregnancy? Will be glad if i get these questions answered through my email.

    1. Hi there, I was wondering how your pregnancy went? Did your fibroid grow any larger? I have a fibroid thats’s 10 by 8cm on the outside of my uterous and was contemplating having a baby.

  2. hi am 27 am supposed to be 9 weeks last week but my u/s is showing 7weeks with only gestational and yolk sac, and I have fibroid measuring 3.25 cm, then on Tues I started seeing blood with no pain through yesterday night, though not much of the blood, but is making me to worry. pls any advice will help

    1. Hi pls see a doc as sometimes fibroids cause mild bleeding or spotting… Also u may have to another USG to see if baby is fine and heart beat is there… Sometimes this bleed or spotting can be due to subchorionic hemorrhage also known as SCH… Best u see ur doc ASAp

  3. I am a fibroid patient aging 45 years whether there is possibility of getting pregnant and also if it is advisable to give birth to a baby at the age of 45

  4. hi

  5. I am 32 year old this my first pregnancy..Now 15 weeks of pregnancy l have 3 fibroids in uterurs ..I have serious pain in my abdomen last three days and i consult with doctor but no response only at the time pain normal again after one day pain is starting… Now what i will do?? Any solution for pain??

  6. Go to the hospital ASAP if the pain is severe. You could be experiencing degeneration of the fibroid, which is very painful but can’t really be detected but rather only diagnosed at the exclusion of other things. They will give you meds for the pain that are the least harmful for the baby. I was 16 weeks pregnant when it happened to me during my first pregnancy last year. I went to the emergency room and could barely walk due to a severe burning pain in my belly. They thought it might have been my appendix. Long story short, I walked out of there without an appendix (which was perfectly healthy) or a baby (also healthy). I am currently 5 wks pregnant and terrified because my large fibroid is still there but at least this time I will know that if I am in pain, it is NOT because of my appendix…

    1. omg! I had the same experience as your’s! I have 4 fibroids, the largest one is almost 11cm! And now I’m 21weeks, everything seems ok, just hope my baby will have enough rooms to growth

  11. i am 41 years old and 18 weeks pregnant. during my last visit to the gyno, i was found to be having 6×7 cm fibroid and i have alot of abdominal pain. my fear is wont this fibroid affect the growth and well being of my child and will this pain continue throughout the pregnancy?

  12. I’m 13 weeks pregnant and I have a 10cm by 10cm fibroid to the right blocking the baby from the cervix. I have been bleeding for a week. The bleeding is getting worse. I went to the hospital yesterday and they did an ultrasound and baby was fine with perfect heartbeat. I’m scared I’m going to miscarriage. I’m 40 and this pregnancy is a miracle. I only have one tube due to an ectopic 12 years ago and I was trying for 6 years and gave up for 4 when I found out that I was pregnant. Is bleeding normal and any other advice would be much appreciated. I also have a urinary tract infection to E. coli that I had for 4 months before I was pregnant and have been on so many courses of antibiotics. I’m back on them now.

    1. Hello, I can tell you what worked for me after being diagnosed with a UTI from E. coli, which entered my blood stream. I was given antibiotics ( on two different occasions while in my first trimester). I refused to take any more antibiotics because they made me feel weird. I researched Garlic pills, 1000mg (per pill), 2 a day after a meal. Took it for three days straight and my UTI was gone! I have not had one since and I am almost 22 weeks pregnant.

  13. Hello
    I am 9weeks gone with 4.3cm fibroid and I am experiencing bleeding. This morning I felt something heavy in my virgina, I rushed to the bathroom and it was a heavy blood cloth. I am not experiencing any stomach pain but I am worried.

  14. I am having lower abdominal pain upon standing and changing position. Low back pain, as well as general ache and pain in the location of my 6cm by 5 cm fibroid (attached at upper left uterus). My baby was in breech position (24 weeks) at my last sonogram last week. Is this normal or is something else going on. This pain just started yesterday.

    1. Good day, am having same pains as yours and am equally 24weeks gone honestly mine is really sevear I can’t even sleep properly.
