Chest Pain During Pregnancy: Understanding Causes and Effective Treatments
Chest pain is a frequent experience during pregnancy and is often harmless. Discover the common causes, symptoms, and safe treatment options to ease your discomfort while ensuring your health and your baby’s safety.

Adjusting to pregnancy means coping with sleepless nights, increased hunger, and frequent bathroom visits. If you start experiencing chest pain, it’s natural to feel concerned. Is this a typical pregnancy symptom or something that requires medical attention?
Chest pain during pregnancy is relatively common and usually not linked to heart problems. Various factors can cause it, and most are harmless. However, occasionally, chest pain may indicate a more serious issue that needs prompt evaluation.
Here’s an in-depth look at what causes chest pain during pregnancy, how to recognize accompanying symptoms, and when it’s crucial to consult your healthcare provider.
Common Symptoms Accompanying Chest Pain in Pregnancy
As pregnancy advances, your body undergoes numerous changes that can increase your heart rate and exert pressure on your lungs and stomach due to your growing baby.
Alongside chest pain, you might notice:
- Shortness of breath
- Difficulty breathing when lying flat or sleeping (consider pregnancy pillows for better comfort)
- Heart palpitations
- Elevated heart rate
- Low blood pressure
- Fatigue
Early Pregnancy Causes of Chest Pain
Anxiety and Stress
The joy of pregnancy can sometimes be accompanied by anxiety, especially if it’s your first pregnancy or following a previous loss. Stress and panic attacks can manifest physically, including chest pain.
Early pregnancy anxiety may bring symptoms such as:
- Chest tightness
- Dizziness
- Restlessness
- Rapid breathing
- Difficulty focusing
Morning Sickness
Nausea and vomiting, commonly known as morning sickness, can occur anytime throughout the day and are caused by hormonal fluctuations. Severe vomiting may irritate your throat and strain chest muscles, leading to chest discomfort.
Lung-Related Issues
Pregnancy can worsen asthma symptoms, leading to chest tightness and pain. Respiratory infections like colds, pneumonia, or severe allergies may also cause chest pain during pregnancy.
Important: Contact your healthcare provider immediately if you develop fever or flu-like symptoms during pregnancy.
Heartburn and Acid Reflux
Heartburn is a frequent cause of chest pain in pregnancy, often mistaken for heart-related pain. Increased progesterone relaxes stomach muscles, allowing acid to reflux into the esophagus, causing a burning sensation in the chest and throat.
Heartburn can occur at any stage but is more common in the later trimesters.
Gas and Indigestion
Digestive changes during pregnancy can lead to gas buildup, causing bloating and chest pain that may mimic heart pain. This discomfort is more prevalent as the baby grows and exerts pressure on the stomach.
Causes of Chest Pain in Later Pregnancy
Breast Changes
Hormonal shifts cause breast enlargement and increased weight, which can strain chest muscles and lead to pain, especially in the third trimester.
Rib and Cartilage Pain
The expanding rib cage stretches cartilage connecting ribs to the breastbone, potentially causing sharp chest pain and tenderness, known as costochondritis.
Blood Clots in the Lungs (Pulmonary Embolism)
Though rare, pulmonary embolism is a serious condition where blood clots block lung arteries. Risk factors include obesity, previous clots, or genetic predispositions. Symptoms include chest pain with deep breaths, coughing pain, rapid heartbeat, and leg swelling.
Seek immediate medical care if you suspect a clot.
Serious Cardiac Conditions
Conditions such as peripartum cardiomyopathy or heart attack are uncommon but possible causes of chest pain in pregnancy and require urgent medical evaluation.
Safe Home Remedies to Alleviate Chest Pain During Pregnancy
Most chest pain during pregnancy can be managed at home with these strategies:
- Practice relaxation techniques like meditation and calming music to reduce anxiety.
- Consult a therapist if anxiety persists.
- Eat small, frequent meals to ease nausea.
- Avoid spicy and heartburn-triggering foods such as tomatoes, chocolate, mint, and citrus.
- Limit gas-inducing foods like processed and sugary items.
- Drink ginger tea to soothe nausea.
- Apply cold compresses for muscle soreness and swelling.
- Use warm compresses or heating pads for rib and muscle pain relief.
- Wear supportive, non-restrictive bras without underwires.
- Sleep on your side and use body pillows to reduce chest pressure.
When to Seek Medical Attention
Contact your healthcare provider promptly if chest pain is severe, persistent, or accompanied by symptoms such as:
- Severe or sudden shortness of breath
- Chest pain worsening with coughing
- Excessive nausea and vomiting
- Heart palpitations or rapid heartbeat
- Headache, blurred vision, or dizziness
- Fainting spells
- Reduced urine output or dark urine
- Swelling in legs, ankles, or face
- One-sided leg swelling or calf pain
Inform your doctor about any personal or family history of blood clots, varicose veins, heart disease, or stroke to assess your risk factors.
Medical Treatments for Chest Pain in Pregnancy
While most cases do not require medical intervention, your doctor may recommend treatments based on the underlying cause, including:
- Adjusting asthma medications to prevent respiratory symptoms
- Prescribing anti-nausea medications and IV fluids for severe morning sickness
- Using compression stockings and encouraging movement to prevent blood clots
- Administering blood thinners postpartum if necessary
- Managing blood pressure with appropriate medications
Summary
Chest pain during pregnancy is commonly benign and unrelated to heart problems. It often results from hormonal changes, physical shifts, stress, or minor illnesses. Nevertheless, persistent or severe chest pain warrants prompt medical evaluation to rule out serious conditions. Always communicate openly with your healthcare provider about any chest discomfort or concerning symptoms during your pregnancy.
