Pregnancy is a time of significant physical and hormonal changes. For women living with Postural Orthostatic Tachycardia Syndrome (POTS), these changes can feel even more intense and unpredictable. While many women with POTS go on to have healthy pregnancies, understanding how the condition interacts with pregnancy is essential for better symptom control and peace of mind.
This guide explores the symptoms, potential risks, and practical management strategies for navigating POTS during pregnancy—based on current clinical insights and patient-centred care approaches.
What Is POTS?
Postural Orthostatic Tachycardia Syndrome (POTS) is a disorder of the autonomic nervous system. It primarily affects blood flow regulation, causing a significant increase in heart rate when moving from lying down to standing.
Common symptoms include:
- Rapid heartbeat (tachycardia)
- Dizziness or lightheadedness
- Fatigue
- Brain fog
- Fainting (in some cases)
- Palpitations
Since pregnancy already impacts circulation and heart rate, it can either worsen or sometimes improve POTS symptoms depending on the individual.
How Pregnancy Affects POTS
Pregnancy naturally increases blood volume by up to 40–50% and causes hormonal shifts that influence vascular tone. These changes can have mixed effects:
Possible Improvements
Some women report symptom relief, especially in the second trimester, due to increased blood volume improving circulation.
Possible Worsening
Others may experience:
- Increased dizziness
- More frequent palpitations
- Extreme fatigue
- Difficulty standing for long periods
The experience is highly individual—there is no one-size-fits-all pattern.
Common POTS Symptoms During Pregnancy
While symptoms may overlap with normal pregnancy changes, POTS-related issues tend to be more intense or persistent.
1. Persistent Tachycardia
A noticeable and sustained increase in heart rate, especially when standing.
2. Severe Fatigue
Beyond typical pregnancy tiredness, it often interferes with daily activities.
3. Dizziness and Lightheadedness
Especially when standing up quickly or standing for long durations.
4. Brain Fog
Difficulty concentrating, memory issues, and mental fatigue.
5. Nausea and GI Issues
While nausea is common in pregnancy, POTS can worsen digestive symptoms due to autonomic dysfunction.

Risks of POTS During Pregnancy
The reassuring news is that POTS is not generally considered life-threatening during pregnancy, but it does require careful monitoring.
Maternal Risks
- Increased risk of fainting (which can lead to falls)
- Dehydration due to blood pooling
- Reduced ability to tolerate physical stress
Pregnancy-Related Risks
Research is still evolving, but some studies suggest:
- Slightly higher chances of preterm delivery
- Increased risk of hyperemesis gravidarum (severe nausea)
- Blood pressure fluctuations
However, most women with POTS deliver healthy babies with proper care.
Diagnosis and Monitoring
If you are already diagnosed with POTS before pregnancy, your healthcare provider will likely adjust your care plan.
If symptoms appear during pregnancy:
- Tilt table tests are usually avoided
- Diagnosis is based on heart rate changes, symptom history, and monitoring
Regular follow-ups with:
- A cardiologist
- An obstetrician familiar with high-risk pregnancies
are strongly recommended.
Management Tips for POTS During Pregnancy
Managing POTS during pregnancy focuses on symptom control and maintaining circulation.
1. Stay Hydrated
Hydration is critical.
- Aim for 2.5–3 litres of fluids daily (or as advised)
- Include electrolyte-rich fluids
2. Increase Salt Intake (If Recommended)
Salt helps retain fluid and improve blood volume.
- Always consult your doctor before increasing sodium intake
3. Wear Compression Garments
Compression stockings can:
- Reduce blood pooling in the legs
- Improve circulation
- Minimize dizziness
4. Prioritise Rest and Positioning
- Avoid standing for long periods
- Sit or lie down when feeling symptomatic
- Elevate legs when resting
5. Gentle Exercise
Light physical activity can help maintain circulation.
Recommended options:
- Prenatal yoga
- Walking
- Recumbent cycling
Avoid overexertion—listen to your body.
6. Eat Small, Frequent Meals
Large meals can divert blood flow to digestion and worsen symptoms.
- Opt for smaller, balanced meals throughout the day
7. Medication Adjustments
Some medications used for POTS may not be safe during pregnancy.
Doctors may:
- Adjust dosages
- Switch to safer alternatives
- Monitor closely for side effects
Never start or stop medication without medical advice.
Labor and Delivery Considerations
With proper planning, labour and delivery can proceed safely.
Key Considerations:
- Vaginal delivery is usually possible
- Epidural anaesthesia may help manage heart rate fluctuations
- Continuous monitoring of heart rate and blood pressure
A personalised birth plan involving your care team is essential.
Postpartum Considerations
After delivery, hormone levels shift again, which can impact POTS symptoms.
What to Expect:
- Some women experience symptom flare-ups
- Others may notice improvement
Tips:
- Continue hydration and salt intake
- Resume gradual exercise
- Seek support—fatigue combined with newborn care can be challenging
When to Seek Medical Help
Contact your doctor if you experience:
- Frequent fainting
- Severe chest pain
- Shortness of breath
- Uncontrolled heart rate
- Reduced fetal movement
Early intervention helps prevent complications.
Emotional and Mental Health Matters
Living with POTS during pregnancy can feel overwhelming. The unpredictability of symptoms, combined with pregnancy changes, can lead to anxiety or frustration.
Helpful strategies:
- Join support groups (online or local)
- Practice relaxation techniques (deep breathing, meditation)
- Maintain open communication with your healthcare team
You don’t have to navigate this alone.
Final Thoughts
POTS during pregnancy can be challenging—but it is manageable with the right care and awareness. Every pregnancy is different, and your experience may not follow a predictable pattern.
The key is proactive management, consistent monitoring, and self-care. With a supportive healthcare team and personalised strategies, many women with POTS go on to have safe pregnancies and healthy babies.
If you’re planning a pregnancy or are currently expecting, working closely with your doctor will help you feel more prepared, confident, and in control.
