Pneumonia is usually triggered by cold climate. It usually occurs during the rains and winters and starts with a common cold or flu. Pneumonia during pregnancy is referred to as maternal pneumonia and could cause some problems for you and the baby. However, the infection is preventable, and with proper care you can avoid the risks.
In this post, MomJunction tells you about pneumonia during pregnancy, its causes, complications, treatment, and prevention.
What Is Pneumonia?
Pneumonia is a bacterial, viral or fungal (rare) infection of one or both the lungs. The lungs are inflamed and become less elastic, thus creating breathing difficulties. The air sacs (alveoli) are inflated with pus or fluid (1).
Pneumonia cases are usually reported during the winter with the damp climatic condition acting as a catalyst for microbes to survive.
Causes Of Maternal Pneumonia
You could get pneumonia during pregnancy as you might have a weak immune system and also because of the reduced lung capacity due to the pressure put by the expanding uterus. These make you susceptible to pneumonia that could be of following types (2) (3).
- Bacterial pneumonia: It is the leading cause of pneumonia that develops either on its own or following viral flu or cold. It mostly affects one lobe or a part of the lung. Some of the common bacteria that cause this infection are Streptococcus pneumonia, mycoplasma pneumonia, and haemophilus influenza.
- Viral pneumonia: Viruses enter the lungs and multiply but show no signs of fluid-filled lungs. Influenza virus, acute respiratory syndrome, and varicella are common viral infections that lead to pneumonia.
- Fungal pneumonia: This is a rare form of pneumonia during pregnancy, and mostly caused by the fungus Coccidioidomycosis, in the third trimester. It could affect immunity and have a stimulating effect on progesterone.
Pregnant women are not likely to get pneumonia more often than non-pregnant women (3). Therefore, the risk factors of pneumonia are the same in pregnant and non-pregnant women.
Factors That Increase The Risk Of Maternal Pneumonia
- Have anemia or asthma
- Are using antepartum corticosteroids (given to improve fetal lung maturity) or tocolytic agents (to help induce labor)
- Smoke, drink regularly
- Have poor nutrition
- Work with young children (who could be the carriers of the infection)
- Frequently visit or spend time at hospitals and nursing homes

Symptoms Of Pneumonia
Just like the risk factors, the symptoms of maternal pneumonia are also the same as those of pneumonia. Common symptoms include (6):
- Cold and/or flu associated with a sore throat, headache and body pains
- Fever and chills
- Cough that gets severe
- Chest pain
- Breathing difficulties or rapid breathing
- Excessive fatigue
- Loss of appetite
If you have these symptoms, visit a doctor. It is good to address them at the beginning because unaddressed pneumonia might lead to some complications in pregnancy.
Complications Of Maternal Pneumonia
Research studies have associated pneumonia during pregnancy with increased maternal morbidity and mortality (7). Severe or neglected pneumonia might lead to complications in the mother and the baby.
For the mother:
- Oxygen levels fall as the lungs cannot produce enough oxygen. This could lead to congestion where fluids accumulate around the lungs, and the infection spreads to other parts of the body, including the bloodstream. This condition is referred to as empyema (4).
- Respiratory failure (2)
For the baby:
- Low birth weight
- Premature birth
The seriousness of the complications necessitates an early diagnosis of pneumonia during pregnancy.
Diagnosis Of Pneumonia During Pregnancy
Before coming up with treatment options, your doctor might (8):
- Assess your symptoms and health history
- Examine your lungs using a stethoscope
- Take chest x-ray
- Collect the sputum sample (phlegm or spit)
If the pneumonia is mild, the doctor might prescribe some antibiotics and suggest you to take rest at home. But if the infection is severe, they might recommend hospital treatment.
Treatment Of Pneumonia During Pregnancy
Your healthcare provider will advise a course of medication that could steadily alleviate your symptoms. Antibiotics are given for bacterial pneumonia and antiviral medications for early-stage viral pneumonia (9).
- Mild pneumonia can be treated at home with enough sleep, fluids, and prescribed medications.
- If you have severe symptoms, you might be given intravenous fluids and antibiotics through a drip, and also oxygen for breathing normally.
- In the case of severe pneumonia, you may be kept in the intensive care unit (ICU) and might require breathing assistance.
Irrespective of the type of infection, you may be advised to have:
- Respiratory therapy to ease breathing difficulties
- Oxygen therapy if the oxygen levels drop
- Nebulization and inhalers to reduce signs of wheezing and shortness of breath
- Over-the-counter pain relievers such as Tylenol (acetaminophen) for fever and pain
Is It Possible To Prevent Pneumonia During Pregnancy?
Though you cannot prevent all types of pneumonia, you can take steps to lower the chances of contracting the infection by taking the below measures:
- Avoid physical contact with those having cold, flu or other infections
- Exercise regularly (that helps build immunity)
- Practice good hygiene
- Eat healthily and have adequate sleep
- Quit smoking
- Avoid places susceptible to bacteria, viral, and fungal pathogens
Flu vaccines may also reduce the risk of contracting the infection, and you can take a flu shot in any trimester. However, you should talk to your doctor about this.
If you receive treatment for pneumonia on time, you will not experience any complications. You should know when to see a doctor so that the treatment is given on time. However, the best way to deal with pneumonia will be to take all possible preventive measures to avoid contracting the infection.
