Why do pregnant women experience palpitations and increased heart rate?

Heart palpitations usually refer to heart rate. Generally, heart palpitations and increased heart rate in pregnant women may be caused by physiological changes, hormonal influences, anemia, hyperthyroidism, arrhythmia, and other factors. These conditions can be improved through appropriate exercise, medication, and other methods. If discomfort occurs, timely medical consultation is recommended. Detailed explanations are as follows:

1. Physiological Changes

During pregnancy, the body increases cardiac output to meet the needs of both the mother and the fetus, which may cause an increased heart rate. This is a normal physiological phenomenon and generally does not require special treatment. It is recommended to maintain adequate rest and avoid excessive fatigue.

2. Hormonal Influences

Due to hormonal changes during pregnancy, such as increased estrogen and progesterone levels, heart function may be affected. Engaging in relaxation exercises, appropriate physical activities like walking or yoga, and maintaining good sleep habits can help alleviate these symptoms.

3. Anemia

Anemia during pregnancy may lead to insufficient oxygen supply, causing the heart to beat faster to compensate. Symptoms such as fatigue and dizziness may also occur. Under a doctor's guidance, medications like vitamin B12 tablets and folic acid tablets can be used to improve anemia symptoms.

4. Arrhythmia

Arrhythmia is generally caused by unhealthy lifestyle habits, heart diseases, or genetic factors. It may lead to irregular heartbeats or rapid heart rate, accompanied by symptoms like palpitations. After consulting a physician, medications such as sotalol hydrochloride tablets or digoxin tablets may be used for regulation.

5. Hyperthyroidism

Thyroid function may increase during pregnancy, potentially accelerating metabolism and causing a faster heart rate, often accompanied by symptoms such as excessive sweating and palpitations. Follow medical advice to use antithyroid medications like propylthiouracil tablets or methimazole tablets, and regularly monitor thyroid function.

During treatment, maintain a light diet and increase the intake of vitamin-rich vegetables and fruits, such as tomatoes, carrots, grapefruits, and apples, which can boost immune function and promote overall health.
