Pregnancy Muscle Aches: What's The Deal?

does pregnancy cause muscle aches

Pregnancy is a time of great change for the body, and aches and pains are a common part of the process. From back pain to varicose veins, there are many types of discomfort that can arise. The cause of these pains is twofold: the body's changing shape and the surge of hormones. As the body changes, the center of gravity shifts, and the muscles and joints become strained. This can lead to musculoskeletal pain, particularly in the third trimester when weight gain and posture changes increase force on joints and soft tissues. Additionally, hormonal changes relax the ligaments and joints, which can also result in body aches and pains. While these aches are a normal part of pregnancy, it is important to consult a doctor or midwife for advice and treatment options.

Hormonal changes

Pregnancy leads to changes in almost every part of a woman's body. One of the most common complaints during pregnancy is muscle pain and body aches. These aches and pains are caused by hormonal changes and mechanical changes in the muscle and ligament structures.

Hormones relax the ligaments and joints to prepare the body for birth, which may result in body aches and pains. As the pregnancy progresses, particularly from the second trimester onwards, weight gain puts extra pressure on the joints. The growing belly pulls the centre of gravity forward and stretches and weakens the abdominal muscles, which support the spine and back. This shift in the centre of gravity can also cause muscle and joint pain.

The uterus expands during pregnancy, and the ligaments that hold it in place stretch, causing a sharp, short burst of pain that feels like a muscle spasm in the lower abdominal area. This pain is known as "round ligament pain" and is more common during the first and second trimesters.

In addition to these hormonal changes, weight gain during pregnancy can also contribute to muscle aches and pains. The extra weight puts more pressure on the joints and nerves, which can lead to pain and discomfort. Staying active and managing weight gain can help prevent and manage muscle aches during pregnancy.

Weight gain

Additionally, weight gain during pregnancy can put extra pressure on your joints, leading to musculoskeletal pain. This can be managed and prevented by staying active throughout the trimesters. Mild to moderate exercises, such as walking, aquafit, and stretching, can help maintain joint mobility and muscle flexibility and strength. Early medical attention is recommended for musculoskeletal pain to avoid unnecessary discomfort.

The weight gain can also compress nerves, causing further pain. This nerve compression is due to the weight gain and water retention, which cause the nerve pathways to swell. To prevent and relieve this type of pain, you can move slowly, avoid sudden movements, and try to take some weight off your uterus by floating in a pool or taking a warm bath. Maternity belts or abdominal support garments can also help.

Furthermore, weight gain during pregnancy can contribute to constipation, which is already common due to hormonal changes slowing digestion and relaxing muscles in the bowels. The added pressure of the expanding uterus on the bowels can lead to constipation and associated stomach pains. To alleviate this, it is recommended to drink eight to ten glasses of water daily, avoid caffeine, and eat fiber-rich foods.

While weight gain during pregnancy can cause muscle aches, it's important to note that staying active and managing weight gain can help prevent and alleviate these issues. Moderate exercise, such as walking, can reduce back pain and improve overall muscle health.

Digestive problems

Hormonal changes during pregnancy can also cause digestive problems. High levels of progesterone relax your intestinal muscles, which can lead to gas and bloating. Constipation is also common during pregnancy, with 75% of pregnant women experiencing it at some point. This can be caused by iron supplements, a diet low in fibre, a lack of fluids, and fluctuating hormones.

If you are experiencing digestive problems during pregnancy, it is important to stay hydrated by drinking lots of water. You should also add more fibre to your diet and try to eat smaller meals more frequently. If constipation is becoming a frequent or serious problem, your doctor can prescribe a stool softener.

In some cases, digestive problems during pregnancy can be a sign of a more serious condition, such as appendicitis, gallstones, or preeclampsia. If you are experiencing severe abdominal pain, especially if it is persistent and accompanied by other symptoms such as vaginal bleeding or a fever, you should seek medical attention.

Muscle cramps

Pregnancy hormones relax the ligaments and joints to prepare the body for childbirth, which may result in muscle aches and pains. As the pregnancy progresses, weight gain puts extra pressure on the joints, and the growing belly pulls the centre of gravity forward, stretching and weakening the abdominal muscles. This can lead to increased strain on the back muscles, resulting in back pain, which is a frequent complaint during pregnancy.

To prevent and manage muscle cramps during pregnancy, it is recommended to stay active throughout the trimesters. Mild to moderate-intensity exercises such as walking, stretching, and aqua fitness help maintain joint mobility, muscle flexibility, and strength. A duration of 20-60 minutes, three to four days a week, is a reasonable goal. Additionally, identifying practitioners in your area with expertise in pregnancy, such as physical therapists, can help provide early medical attention to alleviate unnecessary pain and suffering.

Some self-care measures to alleviate muscle cramps include stretching the muscles by flexing the foot upward and then downward, taking a warm bath or shower, and massaging the affected areas. Maintaining physical activity and staying hydrated throughout the day can also help prevent leg cramping.

Back pain

The lumbar spine undergoes compensatory lordosis, which causes excess strain on the lumbar joints, muscles, ligaments, and discs. The psoas muscle in the hip, which stabilizes the spine and helps in hip and leg movements, is shortened due to the compensatory lordosis, exacerbating the lower back pain symptoms.

Pregnancy also causes hormonal changes, extra weight, and a shift in the centre of gravity, which can lead to back pain. As the uterus grows, the centre of gravity changes, and the weight of the baby pulls the lower spine forward, adding strain to the back muscles. This can also lead to problems with balance and the potential for falls.

Pelvic changes are normal during pregnancy and help accommodate the growing uterus and facilitate birth. However, pregnant women who experience pelvic pain have different amounts of laxity in their right and left sacroiliac joints, which connect the spine to the pelvis. This difference in joint laxity occurs due to a high concentration of the hormone relaxin, which softens the connective tissues and joints. Significant laxity of the sacroiliac joints may cause displacement of the ilium, which is part of the pelvis that attaches to the sacroiliac joint. Pain occurs when the shifted ilium is displaced in an unstable position, causing stress on the adjacent tissues. As the body tries to restore the pelvis back into a normal position, the muscles become tense and pull within or around the pelvis, leading to severe pain.

Frequently asked questions

Yes, muscle aches are common during pregnancy. Hormones relax the ligaments and joints to prepare the body for birth, which may result in body aches and pains.

There are several causes of muscle aches during pregnancy. One cause is the stretching and lengthening of abdominal muscles and connective tissues as the uterus and baby grow. This can cause what is known as diastasis rectus abdominis or ab separation. Another cause is fluid retention, which can put pressure on joints and nerves. Weight gain can also cause muscle aches, as it puts extra pressure on the joints.

Muscle aches can occur at any point during pregnancy, but they are often most bothersome during the third trimester when the baby is bigger.

There are several ways to treat muscle aches during pregnancy. Staying active throughout each trimester can help prevent and manage pain. Moderate exercise, such as walking, aquafit, and stretching, can help maintain joint mobility, muscle flexibility, and strength. Applying heat and/or cold to affected areas may also help.
