Shortness of Breath During Pregnancy: Causes, Risks & When to Seek Help

Pregnancy is a transformative journey that brings about numerous physical changes in a woman’s body. Among the common symptoms experienced, shortness of breath, medically known as dyspnea, it can be particularly concerning for expectant mothers. While it is often a normal part of pregnancy, in some cases, it may signal an underlying respiratory or cardiac condition that needs medical attention.

Prof. Dr. Syed Arshad Husain, a renowned pulmonologist in Dubai, specializes in diagnosing and treating respiratory conditions in pregnant women and offers expert guidance on managing shortness of breath safely and effectively.

Why Does Shortness of Breath Happen During Pregnancy?

Shortness of breath affects nearly 60-70% of pregnant women at some point during their pregnancy. The causes vary depending on the trimester:

First Trimester: Hormonal Changes

In early pregnancy, increased levels of progesterone play a crucial role in stimulating the respiratory center in the brain. This hormone signals the lungs to take in more oxygen, which can cause the feeling of breathlessness even without any physical exertion.

Second Trimester: Diaphragm Elevation

As the uterus grows, it begins to push against the diaphragm—the muscle that helps control breathing. This elevation reduces lung expansion capacity, making it harder to take deep breaths.

Third Trimester: Pressure from the Baby

By the third trimester, the uterus has expanded significantly, placing pressure on the lungs and diaphragm. This mechanical restriction makes it more challenging to breathe comfortably, especially when lying down or after meals.

When is Shortness of Breath Considered Normal?

Mild shortness of breath that gradually progresses during the pregnancy is usually considered normal. It tends to be more noticeable during physical activities like walking upstairs, bending over, or standing for long periods.

However, it's crucial to distinguish between physiological changes and pathological symptoms. According to Dr. Syed Arshad Husain, any sudden, severe, or worsening shortness of breath should not be ignored and requires prompt medical evaluation.

Warning Signs That Require Immediate Attention

While mild breathlessness can be typical during pregnancy, you should consult a specialist if you experience any of the following:

• Sudden onset of breathlessness

• Chest pain or tightness

• Rapid or irregular heartbeat

• Bluish lips or fingertips

• Persistent coughing or wheezing

• High fever or chills

• Swelling in legs or ankles (possible sign of blood clots or heart strain)

• Difficulty lying flat due to breathing discomfort

These symptoms could indicate serious conditions like pulmonary embolism, asthma exacerbation, pneumonia, or pregnancy-induced heart failure.

Common Medical Causes of Severe Dyspnea in Pregnancy

As a leading lung specialist in Dubai, Prof. Dr. Syed Arshad Husain often evaluates and manages the following medical causes of breathlessness during pregnancy:

1. Asthma

Asthma can worsen during pregnancy and needs to be carefully managed to avoid complications for both the mother and the baby.

2. Anemia

Iron deficiency is common in pregnancy and may lead to reduced oxygen-carrying capacity in the blood, making breathing more difficult.

3. Pulmonary Embolism

A life-threatening condition caused by blood clots in the lungs. Pregnant women are at higher risk due to increased clotting factors.

4. Heart Conditions

Pregnancy increases cardiac output. Undiagnosed heart problems may present with dyspnea, fatigue, or palpitations.

5. Pneumonia or Respiratory Infections

Respiratory infections can be more severe in pregnancy due to a slightly suppressed immune system.

Diagnosis & Treatment at Dr. Syed Arshad Husain’s Clinic

When you consult Dr. Syed Arshad Husain, you can expect a detailed assessment involving:

• Complete medical history and symptom analysis

• Chest X-rays (if needed, with abdominal shielding)

• Pulmonary function tests

• Blood oxygen levels

• ECG or echocardiography (if cardiac cause suspected)

Treatment is customized based on the diagnosis. Dr. Husain ensures all medications and procedures are safe for both the mother and the baby.

Tips to Manage Breathlessness During Pregnancy

• Maintain good posture, especially while sitting and sleeping

• Use pillows to prop yourself up while lying down

• Avoid heavy meals that cause bloating

• Stay active with doctor-approved exercises

• Practice breathing techniques like deep belly breathing

• Ensure good iron intake to prevent anemia
