Chronic conditions—such as diabetes, high blood pressure, and autoimmune diseases—increase health risks during pregnancy for any woman, but Black women face additional barriers to care and monitoring that can make these risks harder to manage. Research documents that Black women experience higher rates of serious pregnancy complications and maternal death, and unmanaged chronic illness is one of several contributing factors alongside healthcare access, implicit bias in clinical settings, and reduced continuity of care.
If you have a chronic condition and are pregnant or planning pregnancy, the outcome is not predetermined. Pregnancy planning, close medical oversight, clear communication with your care team, and knowing what warning signs require urgent attention can reduce complications significantly. This article covers how specific chronic conditions interact with pregnancy, what to watch for at each stage, and how to build the care you deserve.

How Chronic Illness Changes During Pregnancy
Pregnancy fundamentally shifts how your body handles a chronic condition. Hormones, blood volume, metabolism, and kidney function all change, which means medications may work differently, disease symptoms may improve or worsen, and your baseline health measures will look different than before pregnancy. For example, blood sugar control often shifts in diabetes, and kidney function can be affected in ways that matter for medication safety.
Your organs also work harder during pregnancy. Your heart pumps 40% more blood, your kidneys filter more waste, and your breathing rate increases. If you have a condition affecting the heart, lungs, or kidneys, pregnancy adds real physiological stress. That is not a reason to avoid pregnancy—it is a reason to plan carefully and monitor closely.
Some conditions improve during pregnancy because of immune system shifts; others flare unpredictably. Lupus, for instance, can do either. Rheumatoid arthritis often improves. Others, like diabetes, require tighter management. Your own condition history is a better guide than generalizations. Pre-pregnancy planning matters because it gives you time to assess which medicines are pregnancy-safe, optimize your current health, and establish a clear communication plan with all your doctors.
Starting pregnancy already in the best possible disease control—with stable medications, good blood glucose or blood pressure numbers, and a team of providers on the same page—improves outcomes measurably. Your gynecologist alone cannot manage your chronic disease during pregnancy. You need coordination between your OB-GYN, your primary specialist (endocrinologist for diabetes, cardiologist for heart disease, rheumatologist for autoimmune disease), and sometimes perinatology if high-risk factors emerge.
Before you become pregnant, confirm that these providers communicate with each other or establish a system for shared records. Pregnancy is not a nine-month emergency. It is a predictable time of change that your entire care team can prepare for in advance. That preparation reduces the crisis moments later on.
Which Chronic Conditions Carry the Highest Pregnancy Risk
Not all chronic illnesses affect pregnancy equally. Conditions that impact the heart, lungs, kidneys, or blood vessels—or those requiring medications that cannot be safely used in pregnancy—demand the most careful planning. Conditions affecting immune function may flare unpredictably. Others have minimal effect on pregnancy if well-controlled. Diabetes (type 1, type 2, or gestational diabetes that persists) is one of the most common and most manageable chronic conditions in pregnancy.
High blood glucose harms the baby's development and increases risks of preeclampsia, miscarriage, and very large babies. Tight blood sugar control before and during pregnancy reduces these risks substantially. Many women with diabetes have successful pregnancies, but planning and frequent monitoring are essential. High blood pressure (hypertension) also affects many black women and carries real pregnancy risk.
Untreated or poorly controlled hypertension can lead to preeclampsia—a dangerous spike in blood pressure during pregnancy—which threatens both mother and baby. Some blood pressure medicines are safe in pregnancy; others are not. If you take blood pressure medication, do not stop it without instruction, but do discuss pregnancy safety with your doctor during planning. Heart disease, whether congenital (present from birth) or acquired, requires specialist input before pregnancy.
Some cardiac conditions carry manageable risk; others carry high risk and warrant a detailed pre-pregnancy conversation with a cardiologist. Pregnancy increases the workload on the heart, so if your heart is already compromised, that matters. Autoimmune diseases such as lupus, rheumatoid arthritis, and thyroid disease can all affect pregnancy. Lupus especially carries increased miscarriage risk and requires close monitoring.
Thyroid dysfunction, if untreated, harms fetal brain development. Many autoimmune diseases are manageable in pregnancy with the right medication adjustments. Kidney disease, even mild chronic kidney disease, affects pregnancy because pregnancy stresses the kidneys further. Medications for kidney protection may need adjustment. Blood pressure management becomes even more critical.
Preconception Planning—Before You Conceive
Ideally, plan pregnancy three to six months ahead if you have a chronic condition. This gives time to optimize medicines, establish baseline health numbers, and coordinate with all your providers. If pregnancy is already underway, the same steps still matter—start immediately, even if you are in your first trimester.
Meet with your primary specialist first—your endocrinologist if you have diabetes, your cardiologist if you have heart disease, your rheumatologist if you have lupus. Bring a list of every medicine and supplement you take, because some are pregnancy-unsafe. Ask directly: "Is this medicine safe to take while I am pregnant or trying to become pregnant?" Do not assume your OB-GYN knows the answer for your specific condition.
Specialists know their field. Request a medication review in writing or a summary from each specialist visit. Take it to your OB-GYN so everyone works from the same list. If a medicine needs to change, plan the switch together so your disease does not flare during the transition. Get baseline measurements: blood glucose if you have diabetes, blood pressure readings over several days, blood tests relevant to your condition.
These become the benchmark for pregnancy monitoring. If your disease is not currently controlled—high blood sugars, high blood pressure, active lupus flare—delay pregnancy if possible until better control is achieved. Uncontrolled disease at conception increases complications. Ask your OB-GYN directly about your risk category: will you be considered high-risk and receive more frequent appointments? What facilities will you deliver at? If your OB-GYN's clinic does not have experience with your specific condition, ask for a referral to maternal-fetal medicine (perinatology).
High-risk pregnancies benefit from specialist oversight. Discuss mental health screening. Black women are screened for depression less often than white women, and pregnancy depression is common. If you have a history of depression or anxiety, discuss monitoring and treatment options now.
Managing Chronic Disease in Early Pregnancy
Once you are pregnant, disease management does not stop—it sharpens. Appointments may increase, blood tests will happen more often, and you will need to track symptoms yourself between visits. This is not overkill; it is the tool that prevents crisis. For diabetes, this usually means more frequent blood glucose checks—daily home monitoring rather than occasional lab tests.
Your target glucose numbers may shift. Many women need insulin for the first time during pregnancy, even if they managed with pills before. This is normal and does not mean you failed or that your disease worsened—pregnancy simply raises the bar for glucose control. Insulin is safe for the baby. For high blood pressure, expect home monitoring and regular clinic checks.
Blood pressure can drop early in pregnancy, which may feel good but can mask real changes. Do not stop medicines without instruction. Some antihypertensive drugs are safe; others—particularly ACE inhibitors and ARBs—are generally avoided in the first and third trimesters, so this is a transition point where medication adjustments happen. For autoimmune disease, your rheumatologist or specialist will advise on medication changes.
Many medicines used for lupus or rheumatoid arthritis are safe in pregnancy; others need to stop. The goal is disease control with safe drugs. If your condition flares during pregnancy—joint swelling, rash, fatigue worsening—report it immediately because active disease can harm the fetus. Thyroid disorders require thyroid testing early in pregnancy because pregnancy changes thyroid needs.
If you take thyroid hormone, your dose often needs to increase. Untreated thyroid disease harms fetal brain development. Tell every healthcare provider at every visit that you are pregnant and list your chronic conditions. Write it down. Do not assume they read your chart. This prevents dangerous medication interactions and unsafe advice.
Pregnancy Complications Tied to Chronic Disease
Several complications occur more often when chronic illness is present. Knowing these allows you to recognize warning signs early. Preeclampsia—a dangerous spike in blood pressure plus protein in the urine or other organ stress—occurs more often in women with hypertension, diabetes, kidney disease, or autoimmune disease. Symptoms include severe headache, upper belly pain, visual changes, and swelling of the face or hands.
Any of these demands urgent evaluation. Miscarriage risk is higher with poorly controlled diabetes and with lupus (especially if anti-phospholipid antibodies are present). This does not mean miscarriage will happen, but it underscores why tight disease control matters early in pregnancy. Stillbirth risk increases slightly with unmanaged diabetes and some other chronic conditions. This is why monitoring increases—regular ultrasounds and fetal movement checks allow detection of problems before they become catastrophic.
Starting around 28 weeks, you should count fetal movements daily. Fewer than ten movements in two hours warrants urgent evaluation. Premature delivery can result from preeclampsia, uncontrolled high blood pressure, or severe infection in women with autoimmune disease. Premature birth carries its own risks, so preventing it through good disease control is critical. Growth problems in the fetus (small for gestational age) are more common with maternal diabetes and some other chronic illnesses.
Serial ultrasounds track fetal growth. Postpartum hemorrhage—excessive bleeding after delivery—is more common in women with certain chronic diseases and in women whose pregnancy was very complicated. Blood loss can be life-threatening, particularly if you are already anemic from kidney disease or active autoimmune disease.
Postpartum Changes and Ongoing Complications
Pregnancy ends at delivery, but your chronic condition does not. The postpartum period (the first six to eight weeks after birth) is a critical transition when disease flares are common, medication doses shift again, and new complications can emerge suddenly. Many serious maternal deaths occur in this window. Blood pressure often rises after delivery, particularly if you had preeclampsia.
This is temporary but can be severe. If you had preeclampsia, blood pressure monitoring continues in the weeks after delivery. Some women develop postpartum preeclampsia—actually more dangerous because it is less expected—days or weeks after delivery. Severe headaches, vision changes, or upper belly pain in those weeks warrant urgent evaluation. If you have diabetes, your insulin needs will drop sharply after delivery because pregnancy hormones vanish.
Insulin doses need quick adjustment to prevent dangerously low blood sugar (hypoglycemia). Do not wait for an appointment; call your endocrinologist immediately after birth to discuss dose changes. For lupus and other autoimmune diseases, flares are common postpartum because pregnancy's immune-dampening effects wear off. Be vigilant for symptom worsening and report it. Some of the medicines you stopped for pregnancy may need to restart.
Infection risk is slightly higher postpartum if you have certain chronic conditions, particularly diabetes or conditions affecting immune function. Fever, chills, foul-smelling discharge, or opening at a surgical incision needs evaluation. Depression and anxiety peak postpartum and occur more often in women with chronic illness, partly from the stress of managing disease while caring for a newborn.
Screening happens at your postpartum visit, but if you feel worse between visits, reach out. Postpartum depression is treatable. Breastfeeding is possible with most chronic conditions, though medicines may need adjustment. Discuss this with both your OB-GYN and your disease specialist before delivery so you know the plan.
Creating Your Prenatal Care Team
Managing pregnancy with chronic disease is not a task for one provider. You need coordination, and that is your responsibility to set up. Ideally, this happens before pregnancy or at your first prenatal visit, not during a crisis. Your OB-GYN or midwife is your primary pregnancy provider and coordinates the overall plan. At the first appointment, provide a written summary of your chronic condition, current medicines, and your other doctors' names and contact information.
Ask specifically: "How will you communicate with my other doctors?" If the answer is vague, ask for a more concrete plan. Some clinics use shared electronic records; others require you to carry printouts between visits. Your primary disease specialist—endocrinologist, cardiologist, rheumatologist—manages your chronic condition during pregnancy but does not manage your pregnancy itself. They see you on their own schedule, usually less often than your OB visits.
Make sure this provider knows you are pregnant and gets your OB's notes. Many specialists have little obstetric training, so they are not making labor decisions, but they are crucial for disease management. If your OB-GYN identifies high-risk features, you may be referred to maternal-fetal medicine (perinatology). Perinatologists have advanced training in complicated pregnancies. They do not replace your OB-GYN; they work alongside.
If you have significant heart disease, severe diabetes, active lupus, or other major conditions, perinatology input is reasonable to discuss. Your primary care doctor, if you have one, should have a copy of your pregnancy and chronic condition summary. They can spot interactions or issues your specialists miss. Nurses, midwives, or health educators at your clinic can teach disease management during pregnancy—how to check blood glucose if you have diabetes, what blood pressure numbers warrant a call, symptom tracking. Build a relationship with at least one clinic staff member who knows your full picture.
Warning Signs That Require Immediate Evaluation
Knowing which symptoms demand urgent care—rather than waiting for the next appointment—is lifesaving. Go to the emergency department immediately or call 911 for: Severe chest pain or shortness of breath—potential heart problem or blood clot. Severe headache, visual changes (blurred vision, loss of sight, flashing lights), or severe upper belly pain—possible preeclampsia or stroke. Vaginal bleeding heavier than a period or vaginal bleeding plus abdominal pain—possible miscarriage or placental abruption.
Loss of consciousness, severe dizziness, or confusion. Fever over 101°F (38.3°C). Severe or worsening leg swelling on one side, especially with calf pain—possible blood clot. Decreased fetal movement (fewer than ten movements in two hours after 28 weeks). Sudden severe pain anywhere. Call your OB-GYN on the same day or by next morning for: Persistent nausea or vomiting preventing nutrition or medicines.
Blood glucose readings far out of range if you have diabetes, despite adjustments. Blood pressure readings 160/110 or higher repeatedly. Signs of infection (fever, foul discharge, warmth or redness at a wound or IV site). Unusual swelling of hands, face, or feet. Worsening joint pain or new autoimmune disease symptoms. Vaginal bleeding (any amount) or brown discharge.
Unusual dizziness or vision changes. Do not minimize or delay because you think you will "seem like a complainer." Pregnancy with chronic disease is medically complex. Your job is to notice and report; your doctor's job is to decide whether evaluation is needed.
Building Trust in Your Care Team
Black women report lower trust in their medical teams, often for documented historical reasons. If you do not feel heard or respected by your care providers, that is real. You also deserve better, and it is your right to change providers or ask directly for change. Before pregnancy, research your OB-GYN or midwife. Many health systems allow this through patient reviews, clinic websites, or asking Black mothers in your community about their experience.
Some practices have a history of listening to Black patients better than others, and it is fair to seek them out. At every visit, advocate clearly. Bring notes if it helps. "I checked my blood glucose seven times a week at the level you recommended, and the readings were X and Y. I want to discuss whether my insulin dose needs adjustment." Specific, factual statements carry more weight than vague concerns.
If your provider dismisses a concern, ask them to document their reason in your chart. "You did not think this was serious—can you write that down?" Providers are less dismissive when they know it is being documented. If you feel unheard consistently, ask for a different provider within the clinic or change clinics. You deserve a team that takes your disease and your concerns seriously.
This is not "difficult" or "ungrateful"; it is medicine. A mismatch between you and your team harms you. Change it.
After Pregnancy—Long-Term Health Planning
Pregnancy changes your body and your disease. A postpartum follow-up visit with your OB-GYN six weeks after birth should include discussion of your pregnancy experience, how your chronic condition fared, and what to watch for going forward. Bring your disease specialist and primary care doctor if possible, or at minimum coordinate with them. Recovery from pregnancy complications takes time.
If you had preeclampsia, high blood pressure, or gestational diabetes during pregnancy, you have higher risk for these conditions long-term. Your OB-GYN should recommend follow-up monitoring—blood pressure checks and glucose testing annually, at minimum. Chronic disease management does not reset after pregnancy. If your medication doses changed during pregnancy, they should be adjusted back or modified based on postpartum disease activity.
Contact your specialists before your postpartum OB visit so the plan is clear. If you want future pregnancies, the insights from this pregnancy matter. Which disease management strategies worked? Which medicines helped? What complications emerged, and why? Use this information to improve the next pregnancy. The same team approach—coordinated care, disease optimization before conception, close monitoring during pregnancy—applies each time.
Birth control choice matters if you do not want immediate pregnancy after delivery. Some methods interact with chronic disease medicines or are not safe for certain conditions. Discuss this at your postpartum visit. Your mental health matters. Many women experience depression or PTSD-like symptoms after complicated pregnancies. Screening and treatment are medical care, not weakness. Discuss this openly with your providers.

Frequently Asked Questions
Can I get pregnant if I have diabetes?
Yes. Pregnancy is possible with type 1 or type 2 diabetes, but tight blood sugar control before and during pregnancy reduces risks of miscarriage, birth defects, and complications. Planning with your endocrinologist three to six months before conception is ideal. Insulin may be needed during pregnancy even if you took pills before—this is normal and safe for the baby.
Is it safe to take my blood pressure medicine during pregnancy?
Some blood pressure medicines are safe in pregnancy; others are not. Do not stop blood pressure medicine on your own—stopping it raises your risk of dangerous complications like preeclampsia. Discuss pregnancy safety with your doctor during planning so any needed medicine changes happen before conception, not during an emergency.
What does preeclampsia feel like?
Preeclampsia causes severe headache, upper belly pain, vision changes (blurred or flashing), or sudden swelling of the hands, face, or feet. These symptoms need urgent emergency evaluation. Untreated preeclampsia threatens both mother and baby. If you have chronic high blood pressure or diabetes, your risk is higher, so report any of these symptoms immediately.
Will my autoimmune disease flare during pregnancy?
It might improve, worsen, or stay the same—every person and every disease is different. Some diseases like rheumatoid arthritis often improve; lupus is unpredictable. Close monitoring by your rheumatologist helps catch flares early. Many medicines used for autoimmune disease are safe in pregnancy, but some need to switch or stop, which is why planning with your specialist before conception matters.
Do I need to see a perinatologist?
If you have significant chronic disease—especially heart disease, diabetes, lupus, kidney disease, or severe hypertension—perinatology (maternal-fetal medicine) input can help. Perinatologists specialize in complicated pregnancies and work alongside your regular OB-GYN. Ask your OB-GYN whether they think this would help your care.
How often will I have appointments if I have a chronic condition?
More often than average pregnancies. You will likely see your OB-GYN every two to four weeks instead of the standard six-to-eight-week intervals between first-trimester visits, and appointments increase again in the third trimester. Your disease specialist sees you on their own schedule, often monthly or more if disease control is tricky. This frequency is normal and necessary—it is how problems get caught early.
