Pregnancy is a beautiful journey filled with anticipation and joy. However, it can also bring various physical discomforts, one of which is pain in the pubic bone. Understanding the causes of this pain is essential for expectant mothers. This article delves into the factors contributing to pubic bone pain during pregnancy, providing insight into this common condition.
Understanding the Pubic Bone
Anatomy of the Pubic Bone
The pubic bone is part of the pelvis, located at the front of the body. It forms the pubic symphysis, a joint that connects the left and right pubic bones. This area plays a crucial role in supporting the body during pregnancy and childbirth. The pubic bone consists of two main components: the body of the pubis, which provides structural support, and the pubic symphysis, which allows for slight movement during various activities. This joint is essential for accommodating the changes that occur as the fetus grows and during the birthing process.
Role During Pregnancy
During pregnancy, the pubic bone supports the growing uterus and accommodates changes in the body. As the pregnancy progresses, the body undergoes several adaptations, which can lead to discomfort in the pubic region. The increase in weight from the developing baby and the stretching of ligaments can create additional pressure on the pubic bone, often resulting in discomfort or pain. This support is crucial not only for the physical changes but also for maintaining balance as the center of gravity shifts.
Causes of Pubic Bone Pain During Pregnancy
Hormonal Changes
Relaxin Hormone
One significant factor contributing to pubic bone pain is the hormone relaxin. Produced during pregnancy, relaxin helps the body prepare for childbirth by loosening ligaments and joints. This increased laxity can result in instability around the pubic area, leading to pain. As relaxin levels rise, they can affect not just the pubic bone but other joints in the pelvis, leading to a feeling of looseness or instability that can contribute to discomfort.
Increased Blood Flow
Pregnancy hormones also cause increased blood flow to the pelvic region. This added circulation can create swelling and discomfort in the pubic bone area. As the blood vessels expand to accommodate this increased flow, it can lead to a feeling of heaviness or pressure in the lower abdomen and pubic region, further complicating the experience of pain.
Physical Changes
Weight Gain
As pregnancy progresses, weight gain is inevitable. The added weight places extra pressure on the pelvis, potentially leading to pain in the pubic bone. This pressure can exacerbate discomfort, especially in the later stages of pregnancy when the baby is larger. The combination of weight gain and changes in body composition can lead to increased strain on the pubic region, often making it difficult to perform everyday activities comfortably.
Posture Changes
With the growing belly, a woman’s center of gravity shifts. This change can lead to altered posture and strain on the back and pelvis. Poor posture can exacerbate pubic bone pain. As the body adapts to this new center of gravity, muscles may compensate in ways that lead to tension and discomfort in the pelvic area.
Muscle Strain
Pelvic Floor Muscles
The pelvic floor muscles support the uterus and bladder. During pregnancy, these muscles endure extra strain as they adapt to the growing baby. Weakness or overuse of these muscles can lead to pain in the pubic area. When these muscles are either overly tense or not strong enough, they can contribute to discomfort, making it challenging for expectant mothers to find relief.
Abdominal Muscles
As the belly expands, the abdominal muscles stretch significantly. This stretching can cause discomfort in the lower abdomen and pubic region, leading to pain. Additionally, if the abdominal muscles become too weak to support the growing weight, it can place additional stress on the pelvic area, increasing the likelihood of pain.
Joint Issues
Pubic Symphysis Dysfunction
Pubic symphysis dysfunction occurs when the joint becomes misaligned or overly relaxed. This condition can lead to sharp pain in the pubic bone, especially when moving or changing positions. Symptoms may include pain during walking, standing, or shifting positions, often making daily tasks challenging.
Sacroiliac Joint Dysfunction
The sacroiliac joint connects the pelvis to the spine. As pregnancy hormones affect this joint, it may become inflamed or misaligned, causing referred pain to the pubic bone. This dysfunction can lead to discomfort that radiates to the lower back and hips, making it crucial to address any underlying issues.
Other Factors
Previous Injuries
Women with a history of pelvic or pubic injuries may experience heightened sensitivity and pain during pregnancy. Previous trauma can lead to a lower pain threshold in the affected area. Past injuries can result in lingering instability or sensitivity, which may be exacerbated by the physical changes of pregnancy.
Inactivity
A sedentary lifestyle during pregnancy can weaken pelvic muscles, making them less capable of supporting the added weight and pressure. This weakness can contribute to discomfort in the pubic area. Engaging in regular, appropriate physical activity can help strengthen these muscles, providing better support and potentially reducing pain.

Activity and Movement
Physical Activity
While some physical activity is beneficial during pregnancy, overexertion can lead to pubic bone pain. High-impact exercises or activities that strain the pelvis should be approached with caution. Finding the right balance between staying active and not overdoing it is crucial for managing pain.
Position Changes
Frequent position changes, especially from sitting to standing, can aggravate pubic bone pain. Taking care when transitioning between positions can help minimize discomfort. Utilizing supportive furniture and moving slowly can make a significant difference in how one feels throughout the day.
Symptoms of Pubic Bone Pain
Characteristics of Pain
Pubic bone pain can vary in intensity and duration. Some women may experience a dull ache, while others may feel sharp or shooting pains. Understanding these characteristics can help in identifying the issue. The variability in pain can also influence how women manage their activities and seek treatment.
Location of Pain
The pain is typically localized around the pubic area but may also radiate to the lower abdomen, hips, or inner thighs. This radiating pain can complicate the diagnosis and management of the condition. Identifying the specific areas of discomfort can aid healthcare providers in offering effective treatments.
Associated Symptoms
Pubic bone pain may accompany other symptoms, such as:
Difficulty walking: Many women report a noticeable increase in discomfort when walking, which can affect mobility.
Pain during sexual intercourse: This can significantly impact intimacy during pregnancy, leading to emotional distress.
Discomfort while changing positions: Simple movements can become challenging, leading to frustration and decreased quality of life.
When to Seek Medical Attention
Severity of Pain
While some discomfort is common during pregnancy, severe or worsening pain warrants medical attention. It is essential to differentiate between normal discomfort and signs of a more serious condition. Seeking early intervention can help prevent complications and ensure a healthier pregnancy.
Accompanying Symptoms
Seek medical advice if pubic bone pain is accompanied by symptoms such as:
Severe abdominal pain: This could indicate a more serious issue that requires immediate attention.
Swelling in the legs: This can be a sign of circulatory issues that may need evaluation.
Unusual bleeding: Any bleeding during pregnancy should be assessed by a healthcare professional promptly.
Consulting a Healthcare Provider
Consulting with a healthcare provider can help determine the cause of the pain and the best course of action. They can perform a physical examination and, if necessary, imaging studies to rule out other conditions. A thorough assessment is crucial for appropriate treatment and management of symptoms.
Conclusion
Experiencing pain in the pubic bone during pregnancy is common and can be attributed to various factors, including hormonal changes, physical strain, and joint issues. Understanding these causes and implementing management strategies can help alleviate discomfort and enhance the pregnancy experience. Always consult a healthcare provider for personalized advice and treatment options. By prioritizing health and well-being, expectant mothers can navigate their pregnancy journey with greater ease and confidence.
