PTTD and Pregnancy: What Expecting Mothers Should Know

Pregnancy changes your body in ways that can affect almost every part of your daily life — and your feet are no exception. If you’re expecting and have noticed new foot pain, arch collapse, or ankle discomfort, you might be wondering whether posterior tibial tendon dysfunction (PTTD) could be involved. Here’s what you need to know about managing foot health during pregnancy.

How Pregnancy Affects Your Feet

During pregnancy, your body undergoes several changes that can impact the posterior tibial tendon and overall foot structure:

  • Weight gain: Most women gain 25-35 pounds during pregnancy, and this added weight places significant stress on your feet and ankles. The posterior tibial tendon already works hard to support your arch — extra pounds means extra demand.

  • Hormone changes: Your body produces relaxin and other hormones that loosen ligaments throughout your body to prepare for childbirth. This affects the ligaments in your feet too, potentially leading to increased pronation (rolling inward) and arch collapse.

  • Fluid retention: Swelling in the feet and ankles is common during pregnancy and can contribute to discomfort and changes in how your shoes fit.

These factors combine to make pregnancy a time when existing foot problems can worsen or new ones can develop.

Warning Signs to Watch For

While some foot discomfort is normal during pregnancy, certain symptoms warrant attention:

  • Pain along the inside of your ankle or foot, particularly after standing or walking
  • Noticeable flattening of your arch that’s new or has gotten worse
  • Swelling that doesn’t go away or is accompanied by pain
  • Difficulty walking or a change in your gait
  • Pain that persists after resting and elevating your feet

If you’re experiencing these symptoms, don’t wait until after delivery to address them. Early intervention typically leads to better outcomes.

Safe Treatment Options During Pregnancy

The good news is that several treatment approaches are safe and effective during pregnancy:

Supportive footwear: Shoes with good arch support and stable heels can make a significant difference. Avoid flat sandals and high heels — a moderate heel with support is ideal.

Over-the-counter orthotics: Generic arch supports found in pharmacies can help distribute pressure more evenly across your feet. Custom orthotics may also be an option after consultation with a podiatrist.

Physical therapy: A physical therapist can teach you exercises to strengthen supporting muscles and stretches to maintain flexibility. Many exercises are safe throughout pregnancy.

Ice and elevation: Applying ice to sore areas and elevating your feet when resting can help manage inflammation and discomfort.

Compression socks: If swelling is an issue, graduated compression socks can improve circulation and reduce edema.

Always consult with your obstetrician before starting any new treatment, and make sure any healthcare provider you see knows you’re pregnant.

When to Seek Professional Care

You should reach out to a healthcare provider if:

  • Pain is severe or affecting your daily activities
  • You notice significant swelling in one foot more than the other
  • Your foot or ankle appears red or warm to the touch
  • Pain persists even with rest and conservative measures
  • You’re unsure whether your symptoms are normal

A podiatrist experienced in treating pregnant patients can evaluate your condition and recommend appropriate interventions that are safe for both you and your baby.

After Delivery: What to Expect

Many pregnancy-related foot changes improve after childbirth, but some women find that foot issues persist or become more apparent once they’re no longer focused on pregnancy. Here’s what to keep in mind:

  • Recovery time: It can take several months for ligaments to tighten back up after delivery. Be patient with your body.

  • Continued care: If symptoms persist, continue with supportive footwear and exercises. Some women benefit from professional physical therapy.

  • Gradual return to activity: Don’t rush back to high-impact exercise. Start slowly and build up gradually.

  • Weight management: Losing pregnancy weight gradually can help reduce stress on your feet as you recover.

The Bottom Line

Foot pain during pregnancy is common but shouldn’t be ignored. While some discomfort is normal, significant pain, swelling, or arch changes could indicate PTTD or other foot conditions that benefit from early treatment. The key is paying attention to your body, seeking care when needed, and being patient with your recovery.

Most women find that with appropriate care, pregnancy-related foot issues improve significantly after delivery. The important thing is to address symptoms proactively rather than suffering through them or assuming they’ll simply go away on their own.
