PCOS living day to day in pregnancy
Informed by recognized medical guidance
Overview
PCOS (polycystic ovary syndrome) is a common hormone condition that affects how your ovaries work. When you have PCOS and are pregnant, you need extra care to keep both you and your baby healthy. This article covers how to manage PCOS day to day during pregnancy.
Key facts
- PCOS can increase your risk of gestational diabetes (high blood sugar during pregnancy) and high blood pressure.
- Many women with PCOS have healthy pregnancies and babies with careful monitoring and lifestyle changes.
- Your healthcare team will watch your blood sugar, blood pressure, and baby's growth more closely than usual.
PCOS affects about 1 in 10 women of childbearing age. Many women with PCOS become pregnant with medical help or on their own, and managing it well during pregnancy is important for a safe outcome.
PCOS affects people who have ovaries, usually starting in their teens or early adulthood. During pregnancy, it affects both the mother and the developing baby if not managed properly.
Symptoms
- Sudden severe headache, vision changes, or chest pain – may be preeclampsia (dangerous high blood pressure)
- Severe abdominal pain, especially with nausea, vomiting, or feeling faint – could be a complication like ovarian torsion or severe preeclampsia
- Seizures or loss of consciousness
- Shortness of breath that gets worse quickly
- Heavy bleeding from the vagina at any stage of pregnancy
- ⚠Blood sugar above your target range that doesn't come down with lifestyle measures (urgent advice from your diabetes team)
- ⚠Blood pressure readings that are higher than normal for two or more checks
- ⚠Persistent vomiting or inability to keep fluids down for more than 24 hours
- ⚠Reduced or absent baby movements (after 24 weeks of pregnancy)
- ⚠Signs of a urinary tract infection (pain or burning when peeing, blood in urine, fever)
Common symptoms
- Excessive weight gain or trouble controlling weight
- Increased thirst and frequent urination (signs of high blood sugar)
- Fatigue and tiredness beyond normal pregnancy fatigue
- Skin changes like acne, dark patches, or excess hair growth
- High blood pressure (sometimes no symptoms, so regular checks are needed)
Causes
Main causes
- Hormonal imbalance – higher levels of male hormones (androgens) and irregular ovulation
- Insulin resistance – your body doesn't use insulin well, leading to higher blood sugar and weight gain
Risk factors
- Family history of PCOS or type 2 diabetes
- Being overweight or obese before pregnancy
- Having had gestational diabetes in a previous pregnancy
- Having a sedentary lifestyle and poor diet
When to see a doctor
See a doctor urgently if:
- Any of the emergency symptoms listed above
- Blood pressure over 140/90 mm Hg that stays high
- Blood sugar over 7.0 mmol/L fasting or over 10.0 mmol/L after meals that doesn't improve
- Feeling very unwell, dizzy, or confused
Book a routine appointment if:
- All scheduled antenatal appointments – your team will check your blood pressure, urine, and weight
- Glucose tolerance test (oral glucose challenge) between 24 and 28 weeks to screen for gestational diabetes
- Any time you have concerns about your baby's movements, your own weight gain, or mood changes
Diagnosis
If you have PCOS, it is usually diagnosed before pregnancy. During pregnancy, your doctor will focus on monitoring for conditions you are at higher risk for, like gestational diabetes and high blood pressure.
Tests that may be done
- Blood tests for blood sugar and HbA1c (average blood sugar over 2-3 months)
- Oral glucose tolerance test (drinking a sugary drink and testing blood sugar levels)
- Blood pressure checks at every visit
- Urine tests to check for protein (a sign of preeclampsia)
- Ultrasounds to monitor your baby's growth and amniotic fluid levels
What to expect at your appointment
Your healthcare team will schedule more frequent checkups than a typical pregnancy – often every 2-4 weeks in early pregnancy, and weekly in the third trimester. They will also discuss a plan for labor and delivery.
Treatment
Treatment during pregnancy focuses on keeping your blood sugar and blood pressure within safe ranges, managing weight gain, and preventing complications. This is done mainly through lifestyle changes and close medical monitoring. Your doctor may suggest certain medications to help control blood sugar or blood pressure, but never take any medication without your doctor's advice.
Self-care at home
- Eat a balanced diet low in refined sugars and high in fibre, lean protein, and healthy fats
- Stay physically active with walking, swimming, or pregnancy-safe exercises (30 minutes most days)
- Monitor your blood sugar at home if you have gestational diabetes – your team will show you how
- Keep a log of your weight, blood pressure (if advised), and baby movements
Medical treatments
If lifestyle changes are not enough, doctors may prescribe medications to control blood sugar or blood pressure. These are chosen to be safe in pregnancy. Do not start or stop any medication without talking to your doctor. In some cases, low-dose aspirin may be recommended to reduce the risk of preeclampsia.
When is surgery considered?
Surgery is very rarely needed during pregnancy for PCOS itself. However, if you have a condition like ovarian torsion (twisted ovary) that causes severe pain, emergency surgery may be required. Your doctor will discuss the risks and benefits.
Living with this condition
Living with PCOS during pregnancy means paying extra attention to your health. You will likely need to check your blood sugar if you have gestational diabetes, eat regular balanced meals, stay active, and attend more medical appointments. It can feel overwhelming, but creating a routine and asking for help from family or friends makes it easier.
Lifestyle tips
- Eat small, frequent meals to keep blood sugar steady
- Drink plenty of water throughout the day
- Get enough sleep (7-9 hours) – poor sleep can affect blood sugar
- Avoid smoking, alcohol, and recreational drugs
- Manage stress with gentle exercise, meditation, or talking to a counsellor
Diet and exercise
Aim for a diet rich in vegetables, whole grains, lean proteins (chicken, fish, tofu), and healthy fats (avocado, nuts, olive oil). Limit sugary drinks, sweets, and white bread. Exercise like brisk walking, swimming, or prenatal yoga for 30 minutes most days helps control blood sugar and manage weight. Always check with your doctor before starting a new exercise routine.
Mental health and emotional wellbeing
PCOS can cause anxiety, depression, or body image concerns – and pregnancy adds extra worry. You may feel stressed about your baby's health or your own body changes. It's normal to have these feelings. Talk to your midwife or doctor; they can refer you to a counsellor or support group. If you feel hopeless, very anxious, or have thoughts of harming yourself, get help immediately.
Prevention
PCOS itself cannot be prevented, but you can reduce the risk of complications during pregnancy by managing your weight and blood sugar before and during pregnancy. If you know you have PCOS, talk to your doctor before getting pregnant to plan the best care.
Screening programmes
Routine screening includes blood pressure checks at every visit, a glucose tolerance test between 24-28 weeks, and urine tests for protein. Some doctors may also check your thyroid function early in pregnancy, as PCOS can be linked to thyroid issues.
Complications
If left untreated
- Gestational diabetes (high blood sugar that can affect the baby's growth and cause early delivery)
- Preeclampsia (dangerously high blood pressure that can harm the mother and baby)
- Preterm birth (baby born too early)
- Large baby (macrosomia) leading to difficult delivery or C-section
- Higher risk of miscarriage or stillbirth (though this is still uncommon with good care)
Long-term outlook
With careful management, most women with PCOS have healthy pregnancies and healthy babies. Your healthcare team will work closely with you to monitor and treat any issues early. The key is to stay engaged in your care, follow your plan, and ask for help when you need it.
