Accelerated pulse after childbirth

Accelerated pulse after childbirth: Heart adaptation

In the first days and weeks after delivery you may notice that your pulse remains accelerated, as it was during pregnancy. This is a normal stage of adaptation of your cardiovascular system to the new conditions. However, sometimes tachycardia can signal conditions that require attention.

Physiological reasons for accelerated pulse

• Changes in blood volume. After delivery your body begins to shed excess fluid. This redistribution creates a temporary load on the heart.
• Blood loss. With blood loss during delivery the heart starts beating faster to compensate for the reduced volume and supply tissues with oxygen.
• Pain and stress. Pain, emotional strain and sleep deprivation activate the sympathetic nervous system, leading to an increased heart rate.
• Dehydration. Insufficient fluid intake can also cause tachycardia.

When should you see a doctor?

Mild acceleration of pulse (up to 100 beats per minute) is usually normal. However, if you notice the following symptoms, be sure to inform your doctor:

• Resting pulse consistently above 100-110 beats per minute.
• Accelerated heartbeat accompanied by chest pain, shortness of breath or severe dizziness.
• High pulse combined with fever or signs of infection.
• High pulse accompanied by pale skin and weakness (could be a sign of anemia).

These symptoms may indicate complications such as excessive blood loss, infection or even thromboembolism. For general aspects of physical recovery read our guide.
