Cystic Fibrosis (CF) and Pregnancy – What You Need to Know

Many times, prenatal diagnosis can lead to early detection of Cystic Fibrosis. Though during the pregnancy period, the condition may get worse and cause respiratory or other symptoms. However, it is possible to get pregnant and carry the baby to its term. Read this article to know the pregnancy outcomes for a mother with Cystic Fibrosis and how to manage pregnancy health with a disciplined lifestyle and routine.

What Is Cystic Fibrosis? 

Cystic Fibrosis is a genetic illness that can affect multiple or all organs of the body. It often causes digestion issues, lung infections leading to respiratory failure. The inherited disease makes the body produce an abnormal quantity of thick and sticky mucus built up in the lungs and pancreas, affecting the respiratory system, pancreas, digestive system, liver, and intestines. The accumulation of mucus causes harmful bacteria to grow in the body.

There is no permanent cure for this disease, however with the improved advancement in treatment, the life expectancy of such patients continues to increase, including women who are getting into the world of motherhood.

What Causes Cystic Fibrosis 

Cystic Fibrosis is inherited genetically. Thus it gets passed on from parents to children through genes. It is caused by the mutation in a gene known as Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). The CFTR gene makes a protein responsible for controlling water and salt movement in and out of your body’s cells. This helps in the production of thin and freely flowing mucus.

When the CFTR gene does not work properly in the body, a thick and sticky mucus builds up. This leads to infection and salty sweat. The mucus clogs the air passage and other ducts and causes Cystic Fibrosis.  

A child inherits a copy of the gene from each parent. When someone inherits a mutated CFTR gene from one parent and a normal CFTR from the other, the person becomes Cystic Fibrosis Carrier. They are usually healthy. However, they are prone to pass the mutated CFTR gene on to their children. Performing carrier testing is a good idea before getting pregnant.

Symptoms of Cystic Fibrosis

Cystic Fibrosis symptoms differ from one person to person and depend on the severity of the disease. The symptoms may continue to improve or worsen with time. People with CF have the following symptoms:

  • Higher levels of salt in the sweat than the normal levels.
  • Frequently occurring sinusitis
  • Persistently coughing, producing thick mucus
  • Recurring lung infections
  • Stuffy nose or inflamed nasal passage
  • Infertility in men
  • Lack of weight gain and growth
  • Blockage in the intestines of the newborn
  • Severe constipation causing rectal prolapse
  • Troubled bowel movements with foul-smelling and greasy stools

Cystic Fibrosis Effects on Pregnancy 

Pregnancy complications who have CF may differ from one person to another. The growing baby could put pressure on the lungs and make it difficult for the mother to breathe. Women often have constipation.  Below listed are some effects during pregnancy:

1. Hypertension (High Blood Pressure) 

During pregnancy, high blood pressure results in increased resistance because of harder blood vessels. This can reduce blood flow to the baby, slow down the baby’s growth, and lead to premature delivery.

2. Premature Delivery 

Major respiratory issues, weight gain, and even poor nutrition increase the chance of premature delivery. Babies born before the 37th week of pregnancy may experience infections and can have breathing issues.

3. Gestational Diabetes 

This happens during pregnancy when a mother has high blood sugar. It can cause issues and difficulties in the developing baby. Diabetes can damage a patient’s eyes and kidneys.

4. Respiratory Issues 

With Cystic Fibrosis, breathing issues escalate quickly in people. It is crucial to get this symptom treated aggressively to receive the required oxygen for the mother’s body and the baby.

5. Nutritional Deficiency 

This can prevent the baby from growing in the womb properly. It could lead to problems in gaining weight by the mother and prevent in maintaining acceptable nutritional requirements.

How Is CF Treated During Pregnancy?
