Strategies for Managing Chronic Conditions During Pregnancy

Managing chronic conditions during pregnancy requires personalized strategies to protect the well-being of the mother and the baby. The spectrum of possible health conditions is complex; the most common chronic conditions encountered in pregnancy include diabetes, hypertension, thyroid disorders, seizure disorders, and autoimmune disorders. 

Focusing on optimal lifestyle modifications and understanding the role of pharmacotherapy helps equip women with the knowledge they need to help manage their own health during pregnancy, promoting optimal health outcomes.

Understanding the Impact of Pregnancy on Chronic Conditions

Pregnancy can impact chronic conditions in various ways.

Physiological Changes: 

The body undergoes a number of physiological changes during pregnancy to accommodate the growing fetus. Blood volume increases by 50%, cardiac output increases by at least 60%, insulin resistance develops, and the hormonal shifts are substantial. 

Although these changes are physiologically expected, they can worsen pre-existing chronic conditions like hypertension or diabetes mellitus. 

Risks to Mother and Baby: 

Managing maternal chronic conditions during pregnancy requires more attentive monitoring and treatment plan adjustments to ensure the health of the mother and the unborn child. 

• Uncontrolled hypertension increases the risk of maternal preeclampsia.
• Poorly controlled diabetes mellitus can lead to macrosomia and problems during delivery.
• Untreated hypothyroidism can cause spontaneous abortion and birth defects.
• Seizure disorders during pregnancy can impair oxygen delivery to the fetus if it is not controlled.

Effective medical treatment can minimize maternal and fetal risks, promoting better outcomes for the mother and baby.

Common Chronic Conditions and Their Management During Pregnancy

The following conditions should be managed by a healthcare provider during pregnancy:

Diabetes: 

Managing gestational diabetes and pre-existing type 2 diabetes mellitus requires careful monitoring and lifestyle modifications. Keeping blood sugar levels stable and within goal ranges is important to promote optimal fetal development. 

Managing blood sugar requires regular glucose monitoring, making substantial dietary changes, and prioritizing regular physical activity. Focusing on a balanced intake of complex carbohydrates, while reducing simple carbohydrates and added sugars, will help control blood sugar while providing sustained energy. In some cases, treatment with medications like metformin or insulin may be necessary to sufficiently control blood glucose levels. 

A multidisciplinary comprised of an obstetrician, a nutrition professional, and a maternal-fetal medicine specialist can help provide personalized treatment plans to promote the best outcomes and reduce the risk of complications.

Hypertension: 

Routine blood pressure monitoring is essential. High blood pressure during pregnancy, whether it is preexisting hypertension or gestational hypertension, can increase the risk of a number of pregnancy-related complications:

• Preeclampsia
• Prematurity
• Low birth weight
• Neonatal intensive care unit admission
• Maternal perinatal death
• Maternal cardiovascular and kidney complications
• Cardiovascular disease later in the offspring

Certain lifestyle modifications may be recommended to help manage hypertension in pregnancy:

• Avoiding processed foods
• Following an anti-inflammatory diet
• Moderating sodium intake
• Stopping smoking
• Getting regular physical exercise
• Managing stress

In some cases, it may be necessary to treat hypertension during pregnancy with medications.  Not all medicines are safe to use during pregnancy. To promote optimal outcomes in the mother and fetus, it is vital to ensure the safety and efficacy of antihypertensive medications. 

Thyroid Disorders: 

For hypothyroidism and hyperthyroidism, it is imperative to adjust medication dosages accurately and perform frequent thyroid function testing to ensure thyroid hormone levels remain within the optimal range throughout the pregnancy. 

Too little thyroid hormone can lead to congenital hypothyroidism, which causes profound intellectual disability in the newborn. On the other hand, uncontrolled hyperthyroidism can cause tachycardia, nausea, vomiting, weight loss, and malnutrition in the mother and fetus.

Autoimmune Disorders: 

In autoimmune conditions like systemic lupus erythematosus and rheumatoid arthritis, the pregnancy course can be highly variable. Some women find that their autoimmune conditions improve, others are unchanged, and yet some have worsened disease manifestations.

It is important to balance the risks and benefits of autoimmune medications to reduce the risk of flare-ups and maintain safety for the mother and the fetus. This often requires collaboration between obstetric and rheumatology specialists. 

Seizure Disorders: 

Seizure disorders present significant risks to the mother and the unborn child by reducing oxygen supply to vital organs. Many anti-seizure medications carry notable side effects, yet they are necessary to reduce the risk of seizures. 

Using a risk vs. benefit approach to treating seizures helps select the best medication options, and working with the patient’s neurologist to ensure adequate treatment promotes the best possible outcomes.

Lifestyle Modifications for Managing Chronic Conditions

The following lifestyle modifications may be recommended by a healthcare professional for the management of chronic conditions during pregnancy:

Diet and Nutrition: 

A balanced diet is vital to manage chronic medical conditions during pregnancy. For hypertension, the Dietary Approaches to Stop Hypertension (DASH) diet is known to improve blood pressure control. This DASH diet controls sodium intake to 2300 mg per day, and it also promotes fruits, vegetables, whole grains, and it limits saturated fats. 

High-fiber diets have also been shown to improve blood pressure control in pregnancy. It is important to understand that low-salt diets in pregnancy (less than 3000 mg of sodium per day) are not universally recommended to prevent hypertension, based on the lack of evidence.

Optimal nutrition is essential for controlling diabetes in pregnancy. Prioritizing a diet high in fiber, low glycemic, and moderate carbohydrates has been shown to improve blood glucose control. 

Weight gain strategies during pregnancy, focusing on nutrient-dense foods in appropriate portion sizes, will help control blood sugar and blood pressure and help prevent metabolic complications during pregnancy. 

Adopting personalized nutrition recommendations has been shown to improve nutrition status of the mother and the offspring, both during pregnancy and later in life. Integrative nutrition emphasizes a holistic approach that considers the whole person and promotes vitality.

Physical Activity: 

Regular physical activity during pregnancy provides many benefits to maternal and fetal health, such as reduced risk of preterm birth, lower rates of preeclampsia, fewer cases of gestational diabetes mellitus, controlled weight gain, better mental health outcomes, and improved overall health. 

It can also help manage chronic conditions like preexisting hypertension and diabetes. While not all activities are safe during pregnancy, low-impact exercises like walking, swimming, biking, yoga, light weight training, and bodyweight movements are generally safe.  

Some specific exercises necessitate caution, such as those with a risk of falling or abdominal trauma and supine exercises after the first trimester. Consult with a healthcare professional before starting any new exercise regimen.

Stress Reduction: 

Stress reduction techniques like yoga, meditation, mindfulness, relaxation, relationships, and spirituality have been shown to help manage chronic conditions, improve mental health, and promote overall well-being during pregnancy. 

Chronic stress promotes increased cortisol levels and proinflammatory cytokine release, which can decrease immune function and increase the risk of preterm birth, preeclampsia, and neonatal morbidity. Prioritizing stress reduction helps optimize maternal health and the health of the offspring.

Medication Management During Pregnancy

When medications are necessary during pregnancy, it is important to evaluate their safety and to adjust or change medications that cause fetal toxicity. This requires good communication between patients and healthcare providers to understand the risks and benefits of pharmacological treatment. Continued monitoring and adjustments to meet the changing demands during pregnancy promote optimal health outcomes.

Non-Pharmaceutical Options: 

Alternative therapies and supplements to treat chronic conditions may be safer options during pregnancy. However, given the ethical concerns of randomized controlled trials during pregnancy, there is less evidence and testing of supplements during pregnancy. Therefore, it is important to discuss the risks and benefits of the use of supplements and alternative therapies with a healthcare provider during pregnancy.
