Back pain is a common complaint during pregnancy, often caused by the growing baby putting extra strain on the spine and pelvic joints. While it might seem like an inevitable part of pregnancy, there are many things you can do to manage and alleviate this discomfort. One simple yet effective method is to focus on maintaining proper standing posture.  

As your baby grows, your center of gravity shifts forward, which can lead to an exaggerated curve in your lower back. To counteract this, try to stand with your feet shoulder-width apart, knees slightly bent. Engage your core muscles, as if you're trying to draw your belly button towards your spine. Keep your shoulders relaxed and down, and avoid locking your knees. This posture helps to distribute your weight more evenly and can significantly reduce strain on your back.  

When standing for extended periods, it can be helpful to shift your weight from one foot to the other periodically. You can also try placing one foot on a small stool to relieve pressure on your lower back. Additionally, using a pregnancy support belt can provide extra support and stability.  

Remember, it's important to listen to your body and take breaks when needed. If you experience severe or persistent back pain, consult with your healthcare provider. By incorporating proper standing posture into your daily routine, you can help alleviate back pain and enjoy a more comfortable pregnancy.
