Why Does My Lower Abdomen Hurt When I Cough?

When you cough, it's not uncommon to feel pain in your lower abdomen. This discomfort is often caused by the strain placed on the rectus abdominis muscles due to excessive coughing. During a cough, multiple respiratory muscles—including the intercostal muscles, diaphragm, and accessory muscles like the rectus abdominis—contract forcefully.

Intense or prolonged coughing can lead to muscle strain, especially in the abdominal region. The more forceful the cough, the greater the contraction of these muscles. Over time, repeated strain can result in soreness or sharp pain in the lower abdomen, similar to the muscle aches experienced after intense physical activity.

In some cases, chronic or violent coughing can lead to more serious complications such as rib fractures, pneumothorax (collapsed lung), or persistent abdominal muscle pain. This type of pain should not be ignored, especially if it worsens with movement or continues even when you're not coughing.

If you experience abdominal pain while coughing, it may be beneficial to take steps to reduce the intensity of your coughing fits. Instead of forcing a cough, try controlled expectoration techniques to clear mucus more gently. Resting the abdominal muscles and staying hydrated can also help reduce discomfort.

In summary, lower abdominal pain during coughing is typically related to muscle strain from forceful or frequent contractions. Managing your cough properly can help prevent further injury and relieve existing discomfort. If the pain persists or becomes severe, consulting a healthcare professional is highly recommended.
