Fibroid Symptoms
What’s Normal & What’s Not?
Uterine fibroid symptoms can consist of heavy bleeding, pelvic pain, weight gain, sciatic nerve pain, leg pain, back pain, and pregnancy challenges. Our Fibroid Specialists go in-depth on uterine fibroids’ common and not-so-common symptoms.

For women that are affected by uterine fibroids, it’s no secret that heavy bleeding and pelvic pain are its most common fibroid symptoms, but your fibroids can affect your body and your health in other ways that you might not have realized. We’re talking about weight gain, period pain, and pregnancy challenges. We’re also talking about bloating, back pain, pelvic pain, sciatica, and bathroom difficulties.
Uterine fibroid symptoms can vary widely depending on number, location, and size of fibroids in the affected individual. Check out this fibroid symptom review to learn more. Generally speaking, severity of symptoms correlates with fibroid size, with larger fibroids causing more intolerable symptoms. This is why treatments that shrink fibroids are effective at alleviating heavy bleeding, fibroid pain, and other symptoms. Ask your doctor the right questions about fibroids.

Fibroid Symptom Reliefin Los Angeles

“I recently had the uterine fibroid embolization (UFE) procedure,have received this procedure because I had EXTREMELY heavy menstrual bleeding and as a result was very anemic. I was weak, felt tired all of the time, and was also experiencing hair loss. Soon after my UFE procedure was completed, my bleeding slowed down significantly. I no longer have to schedule activities around my menstrual cycle or carry extra clothing (or wear diapers) with me when I am going places. I am so happy to have my life back. I was so shocked to see relief from the menstrual bleeding this quickly. I am extremely grateful to the Dr. Lalezarian’s expertise in performing this procedure. Dr. Lalezarian is an excellent doctor and you can tell he really cares about his patients. During my recovery after the UFE procedure, he provided me with his pager so that I can reach out to him if I had any questions, which I really appreciated.”

Can Fibroids Cause Heavy Bleeding?
Yes, heavy menstrual bleeding is the most common symptom reported by women with uterine fibroids [1]. Bleeding abnormalities are not exclusive to uterine fibroids and may indicate another condition, but women with a diagnosis of uterine fibroids report bleeding problems 2-3 times more frequently than women without a diagnosis of uterine fibroids [2].
Bleeding abnormalities caused by uterine fibroids include [2]:
• Heavy menstrual bleeding with fibroids
• Prolonged duration of menstrual bleeding – longer than 6 days [3]
• Fibroids bleeding between periods
• Frequent periods – more often than every 24 days [3]
• Irregular / unpredictable periods
Many women with excessive menstrual bleeding mistakenly assume that their heavy periods are normal and do not seek care [4]. In some women, excessive bleeding can be severe enough to cause iron-deficiency anemia; leading to fatigue, weakness, headaches, dizziness, and other more severe complications. Other women experience day-to-day discomfort, social isolation, and loss of productivity as a consequence of managing heavy periods [1,2].
If your periods are abnormally heavy, last longer than a week, or you’re experiencing bleeding between periods, you may be living with uterine fibroids.

Can Fibroids Cause Pelvic & Back Pain?
Yes, persistent pelvic pain and back pain are common complaints amongst women with fibroids, and one of the leading reasons that women seek treatment for their fibroids. Although uterine fibroids aren’t life threatening, the symptoms of fibroids can be a major drag on quality of life. Fibroids may also press on the sciatic nerve, causing sciatic nerve pain that can radiate down the leg.
Variations in the number of fibroids, fibroid size, and fibroid location can cause a variety of pain patterns that differ from person to person [2,4,5]. These include:
• Chronic pelvic pain
• Acute pelvic pain
• Back pain
• Sciatic nerve pain / leg pain
• Pain during intercourse
• Pain when using the bathroom
Uterine fibroids can cause a persistent pain or pressure in the pelvis that lasts indefinitely called ‘chronic pain’. Posterior fibroids (on the back side of the uterus) may cause lower back pain or rectal pain as they impinge on the nearby anatomy, while anterior fibroids (on the front side of the uterus) can contribute to anterior pelvic pain, pressure sensations, and urinary complications.
‘Acute pain,’ on the other hand, typically refers to significant pain that has a rapid onset and is resolved with treatment. In the case of uterine fibroids, there are a few known sources of acute pain that are directly caused by fibroids:
• Pedunculated fibroids (fibroids that grow on stalks) can get twisted, which can be very painful [4].
• Submucosal fibroids that grow underneath the uterine lining can cause the cervix to stretch, causing pain [5].
• Fibroids can undergo ‘red degeneration’ (death of the fibroid cells), usually during pregnancy [5].
• Pain during intercourse is commonly reported by women with fibroids [2].
Can Fibroids Cause Sciatica?
In less common cases, fibroids may cause sciatica. Sciatica refers to pain that is associated with your sciatic nerve, which runs from your lower back to your legs. Sciatica can occur if the uterine fibroids are pressing against the sciatic nerve, causing sciatic nerve pain that can radiate down the leg [5].
If you’re experiencing persistent pelvic pain, pain during intercourse, sciatic nerve pain, leg pain, back pain, or pain when using the bathroom, you may be living with fibroids.
Do Fibroids Cause Weight Gain?
Yes, uterine fibroids can cause weight gain. Uterine fibroids can vary in size from small ‘seedlings’ to large masses that fill the entire abdomen. As fibroids grow, the uterus expands to accommodate them similar to how it expands throughout a pregnancy [4].
As fibroids grow, women may experience:
• An enlarged uterus
• Unexplained weight gain
• Weight gain around the abdomen and pelvis
• Bloating
Growth rates of fibroids vary significantly depending on age and race [6]. In many cases, fibroids remain small and inconsequential, which is part of the reason why so many women have asymptomatic fibroids. In other cases, fibroids undergo phases of rapid growth, causing visible distention of the abdominal region and pelvic pressure, among other symptoms [7,8].
A physical exam is usually sufficient to estimate the size of your uterus. A normal sized uterus is roughly the size of a small pear and is deep inside the pelvis. As it grows due to fibroids, its size is described as compared to a gravid, or pregnant, uterus. A benchmark that many physicians use is that a 12 week pregnant uterus is felt at the pelvic bone and is the size of a grapefruit, while at 20 weeks the uterus is felt at the umbilicus (around the belly button) [9]. They can use this to estimate the size of the uterus depending on where they feel it in the abdomen. The bigger it is, the more likelihood that the symptoms a woman experiences are worse.
If you’ve experienced unexplained weight gain, abdominal bloating, or if you’ve noticed your tummy expanding, you may be living with uterine fibroids.

Fibroids and Period Pain
Painful cramping just before or during your period is normal, but recurrent pain throughout the rest of your menstrual cycle (what we call ‘cyclic pain’) may be caused by uterine fibroids. It is 2 to 3 times more common for women with uterine fibroids to experience abnormal pain after their period ends or mid-cycle pain when ovulating than it is for women without uterine fibroids. In addition to more frequent cycle pain, women with uterine fibroids report more pelvic pain throughout all phases of their menstrual cycle than women without uterine fibroids [2].
Women should be particularly suspicious of uterine fibroids if they experience:
• Pain after their period ends
• Pain occurring mid-cycle (around 10 days after the end of your last period)
• Excessively painful periods
• Abnormal pain during their menstrual cycle
The exact relationship between fibroid size, location, and pain at various points throughout the menstrual cycle is not well understood. Uterine fibroids can grow to significant sizes very quickly [5], possibly causing menstrual cycle abnormalities. Women concerned about the possibility of having uterine fibroids should take extra care to monitor their entire menstrual cycle for recurring pain patterns and bleeding irregularities.
If you experience pain after your period, excessive pain during periods, or abnormal pain throughout your menstrual cycle, you may be living with uterine fibroids.

Surgical vs. Non-Surgical Fibroid Treatments: Which Is Best?
When it comes to fibroid treatment, we believe that less is more. A less invasive procedure means less trauma, less risk, and shorter recovery time. Learn more about why we opt for UFE, the least invasive treatment for uterine fibroids.
