The uterus is typically around three inches long and resembles the shape of a pear. However, when fibroids develop, they can cause noticeable changes in size and weight. While small fibroids may remain undetected, larger fibroids can significantly enlarge the uterus, sometimes to the extent that it mimics a pregnancy.
How Large Can Fibroids Grow?
Fibroids can vary significantly in size. They may develop as a single mass or in clusters and range from as small as a pea to as large as a watermelon. In extreme cases, fibroids have been known to grow large enough to expand the uterus to the size of a third-trimester pregnancy.
Fibroid Size Comparisons
Here’s a simple guide to understanding the different fibroid sizes:
● Small Fibroids (1cm – 5cm): Comparable to a pea or lime size.
● Medium Fibroids (5cm – 10cm): About a peach or large lemon size.
● Large Fibroids (10cm+): Can grow to the size of a mango or watermelon.
Effects of Larger Fibroids
When fibroids increase in size, they can start affecting the body in various ways. Some of the most common symptoms include:
● Swelling of the abdomen
● Unexplained weight gain
● Pelvic discomfort or pain
● Increased frequency of urination
● A feeling of fullness or bloating
As fibroids grow, they take up space within the abdomen, sometimes pushing against other organs and leading to further complications.
Do Fibroids Cause Weight Gain?
Fibroids do not directly cause weight gain in the way that metabolic changes would. However, a fibroid’s physical bulk contributes to abdominal weight gain when it reaches bigger sizes. Sizeable fibroids have been identified that weigh multiple pounds. Women who have several fibroids develop more visible weight and body changes.
The Link Between Fibroids and Abdominal Bulge
Larger fibroids can stretch the uterus and lead to a visible abdominal bulge. This may cause women to appear as if they are in the early stages of pregnancy. The increased girth is usually due to the mass of the fibroids rather than actual weight gain from fat accumulation.
Extreme Cases of Fibroid Growth
Although most fibroids remain small, there have been extreme cases where fibroids grow to astonishing sizes. In one instance, a woman in Singapore had a 61-pound fibroid removed. While such cases are rare, they highlight the importance of monitoring fibroid growth and seeking medical advice if symptoms become severe.
How Much Weight Can You Gain from Fibroids?
Most fibroids do not contribute significantly to overall body weight. Small fibroids measure just a few grams, while larger ones weigh around four to five pounds. Fibroids that grow too large affect your weight because of their increased bulk.
Managing Fibroids and Their Effects
While fibroids are benign, their impact on a woman’s health and comfort varies. Treatment options include:
● Medications – To regulate hormones and reduce symptoms.
● Non-invasive procedures include uterine fibroid embolization (UFE) to shrink fibroids.
● Surgical options – Including myomectomy (removal of fibroids) or hysterectomy (removal of the uterus in severe cases).
When to See a Doctor
If you notice a persistent abdominal bulge, unexplained weight gain, or discomfort in your pelvic region, it is crucial to consult a doctor. Fibroids that exceed four inches in diameter should be evaluated, as they can begin to impact surrounding organs such as the bladder and intestines. Large fibroids can also increase the risk of complications like blood clots or ruptures.
Final Thoughts
When fibroids develop in the uterus, they change size and weight and become visible throughout the woman’s body. Small fibroids often show no symptoms, but larger fibroids create pain and belly bulging. Visit a healthcare provider when you notice symptoms to receive proper fibroid treatment.
