Your health matters just as much as your baby's. If you are dealing with severe heartburn and gerd in pregnancy, here is what you need to know.
The short answer
Heartburn (gastroesophageal reflux) is extremely common in pregnancy, affecting up to 80% of pregnant people. It is caused by the hormone progesterone relaxing the valve between the stomach and esophagus, and by the growing uterus pushing up against the stomach. While very uncomfortable, it is not harmful to you or your baby.
Key takeaways
- Heartburn (gastroesophageal reflux) is extremely common in pregnancy, affecting up to 80% of pregnant people. It is caused by the hormone progesterone relaxing the valve between the stomach and esophagus, and by the growing uterus pushing up against the stomach. While very uncomfortable, it is not harmful to you or your baby.
- Usually normal when: Burning sensation behind the breastbone after eating or when lying down
- Call your doctor if: Severe chest pain that feels different from typical heartburn, especially if accompanied by shortness of breath, jaw or arm pain, or sweating
- Varies by age — see the age-by-age breakdown below
“About 1 in 8 women experience symptoms of postpartum depression. If you have symptoms of depression that last longer than 2 weeks, tell your health care provider.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to ACOG, NIH, March of Dimes guidelines, heartburn (gastroesophageal reflux) is extremely common in pregnancy, affecting up to 80% of pregnant people. It is caused by the hormone progesterone relaxing the valve between the stomach and esophagus, and by the growing uterus pushing up against the stomach. While very uncomfortable, it is not harmful to you or your baby. At First trimester, heartburn may begin early due to rising progesterone levels that relax the lower esophageal sphincter. Eating smaller, more frequent meals, avoiding spicy or acidic foods, and not lying down right after eating can help. Many antacids are safe in pregnancy, but check with your provider before taking any medication. It is generally considered normal when burning sensation behind the breastbone after eating or when lying down. However, you should contact your pediatrician promptly if severe chest pain that feels different from typical heartburn, especially if accompanied by shortness of breath, jaw or arm pain, or sweating.
Normal vs. Concerning
By Age
What to expect by age
First trimester
Heartburn may begin early due to rising progesterone levels that relax the lower esophageal sphincter. Eating smaller, more frequent meals, avoiding spicy or acidic foods, and not lying down right after eating can help. Many antacids are safe in pregnancy, but check with your provider before taking any medication.
Second trimester
Heartburn often worsens as the uterus grows and progesterone levels continue to rise. Elevating the head of your bed, eating your last meal 2-3 hours before lying down, and wearing loose-fitting clothing can help. Over-the-counter antacids containing calcium carbonate are generally considered safe.
Third trimester
This is when heartburn is typically worst, as the large uterus pushes the stomach upward. If lifestyle changes and antacids are not enough, your provider may recommend H2 blockers or proton pump inhibitors that are considered safe in pregnancy. Heartburn usually resolves quickly after delivery.
What to Tell Your Pediatrician
- Describe when you first noticed severe heartburn and gerd in pregnancy and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if heartburn is severe and not controlled by diet changes and over-the-counter antacids.
- Mention if you are losing weight because eating triggers too much discomfort.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Burning sensation behind the breastbone after eating or when lying down
- Symptoms worsen with large meals, spicy foods, citrus, or chocolate
- Heartburn improves with antacids, smaller meals, or sleeping with head elevated
- Symptoms are worse in the third trimester and improve after delivery
- Heartburn is severe and not controlled by diet changes and over-the-counter antacids
- You are losing weight because eating triggers too much discomfort
- You experience difficulty swallowing or feel food getting stuck
- Severe chest pain that feels different from typical heartburn, especially if accompanied by shortness of breath, jaw or arm pain, or sweating
- Vomiting blood or dark material that looks like coffee grounds
- Severe upper abdominal pain, especially on the right side, which could indicate a more serious condition like HELLP syndrome or gallstones
What You Can Do at Home
- Keep track of when you notice severe heartburn and gerd in pregnancy — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that burning sensation behind the breastbone after eating or when lying down — this is generally within the range of normal.
- At First trimester, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Prioritize your own rest and nutrition. Accept help when offered, and do not hesitate to reach out to your healthcare provider.

Constipation During Pregnancy
Constipation affects up to 40% of pregnant people and is caused by the hormone progesterone slowing digestive transit, iron supplements, a growing uterus pressing on the intestines, and reduced physical activity. It can be managed with increased fiber, fluids, and gentle exercise.
Gallstones During Pregnancy
Gallstones are more common during pregnancy due to elevated estrogen and progesterone, which increase cholesterol in bile and slow gallbladder emptying. They affect 5-12% of pregnant people. Many gallstones cause no symptoms, but gallbladder attacks can cause severe pain in the upper right abdomen and may require treatment.

Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
20-Week Anatomy Scan Unexpected Findings
The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
