Breathing Problem in Pregnancy - What to Expect, Solutions

Experiencing a breathing problem in early pregnancy or the latter part of pregnancy can be a cause of concern. Below we discuss in detail the various reasons for breathing problems during the three trimesters.

First Trimester

Breathing problems are not commonly reported during the first trimester of pregnancy, but they can occur in some women. Some possible causes of a breathing problem in pregnancy - first trimester include:

1. Hormonal changes: During the first trimester of pregnancy, the body produces higher levels of progesterone, which can cause muscles in the diaphragm and lungs to relax. This can make it hard during pregnancy to take deep breaths.
2. Anxiety or stress: The early stages of pregnancy can be a time of high anxiety and stress, which can cause rapid breathing or shortness of breath.
3. Pre-existing medical conditions: Women with pre-existing medical conditions, such as chronic obstructive pulmonary disease or asthma, may experience breathing problems during the first trimester of pregnancy.
4. Infections: In rare cases, respiratory infections such as bronchitis or pneumonia can cause breathing problems during the first trimester of pregnancy.

Second Trimester

Breathing problems in pregnancy can occur in some women during the second trimester. Some possible causes of breathing problems in the second trimester include:

1. Uterine growth: The uterus grows and expands during the second trimester. It can push up against the diaphragm and lungs, making it more difficult to take deep breaths and causing a feeling of breathlessness.
2. Hormonal changes: During the second trimester of pregnancy, the body continues to produce higher levels of progesterone, which can cause muscles in the diaphragm and lungs to relax.
   1. This can make it more difficult to take deep breaths and can cause a feeling of shortness of breath.
3. Anaemia: Some pregnant women may develop anaemia during the second trimester, a condition in which the body has lesser red blood cells to carry oxygen to the tissues. This can cause fatigue and shortness of breath.
4. Asthma: Women with asthma may experience worsening symptoms during the second trimester due to hormonal changes or other factors.
5. Pre-eclampsia: It is a pregnancy-related condition characterised by high blood pressure and damage to organs such as the liver and kidneys.
   1. It typically occurs after the 20th week of pregnancy and can be life-threatening if left untreated. It can also cause shortness of breath due to fluid buildup in the lungs.

Third Trimester

Breathing problems are common in the third trimester of pregnancy and can be caused by various factors. Some possible causes of difficulty breathing in the third trimester include: 

1. Further uterine growth: As the uterus further continues to grow and expand in the third trimester, the pressure against the diaphragm and lungs increases. This makes the breathing problem in pregnancy acute.
2. Hormonal changes: During the third trimester of pregnancy, the body produces higher levels of oestrogen and progesterone. These hormones help support the pregnancy and prepare the body for delivery.
   1. These hormonal changes can also impact a woman's breathing, making it more difficult for muscles in the diaphragm and lungs to relax. 
3. Baby's position: As the baby grows and gets into the position for delivery, it can put pressure on the diaphragm and lungs, making it more difficult to take deep breaths.
4. Untreated Anaemia: Anaemia can also cause breathing problems in the third trimester. If left untreated in the second trimester, then pregnant women with severe anaemia have fewer red blood cells that carry less oxygen to their body tissues.
   1. This causes fatigue and shortness of breath.
5. Heart or lung conditions: Women with pre-existing heart or lung conditions may experience worsening symptoms during the third trimester due to the added stress on the body.
6. Peripartum cardiomyopathy: Also known as PPCM, it is a rare form of heart failure that occurs in women during the last month of pregnancy or up to five months after giving birth.
   1. It is characterised by weakened heart muscles, which can lead to symptoms such as shortness of breath, swelling in the legs, ankles, or feet, rapid or irregular heartbeat, and chest pain or discomfort.
7. Pulmonary embolism in pregnancy: A serious and potentially life-threatening condition, pulmonary embolism (PE) can occur when a blood clot travels to the lungs during pregnancy or shortly after delivery.
   1. Pregnant women are at an increased risk of developing blood clots due to changes in blood flow and increased clotting factors.

Breathing problems during pregnancy are a common issue that affects many women. The increased demand for oxygen by the developing fetus, changes in hormone levels, and changes in the woman's body due to pregnancy can all contribute to breathing difficulties.

Other possible causes of breathing problems during pregnancy include pre-existing respiratory conditions, such as asthma or allergies, and pregnancy-related conditions, such as preeclampsia, gestational diabetes, and obesity.

You should call your doctor immediately if you experience any of the following symptoms:

1. Sudden onset of shortness of breath
2. Chest pain or discomfort
3. Rapid or irregular heartbeat
4. Persistent cough, which may produce blood-streaked mucus
5. Fainting or dizziness
6. Bluish tint to your skin, lips or nail beds

These symptoms could be signs of a serious medical condition such as pulmonary embolism or preeclampsia. It is important to get prompt medical attention to determine the cause of your symptoms and to receive appropriate treatment.

Breathing problems in pregnancy can frequently occur in various stages and trimesters. It is important to discuss any breathing difficulties you may be experiencing with your healthcare provider. They can help determine the cause of your symptoms and recommend the appropriate treatment. 

In some cases, breathing difficulties during pregnancy may signify a more serious condition, such as pre-eclampsia. So, it is important to seek medical attention.
