Relieving heartburn during pregnancy

Indigestion and heartburn in pregnancy

Indigestion, also called heartburn or acid reflux, is common in pregnancy. It can be caused by hormonal changes and the growing baby pressing against your stomach. 

You can help ease indigestion and heartburn by making changes to your diet and lifestyle, and there are medicines that are safe to take in pregnancy.

Symptoms of indigestion and heartburn

Symptoms of indigestion and heartburn include:

• a burning sensation or pain in the chest
• feeling full, heavy or bloated
• burping or belching
• feeling or being sick
• bringing up food

Symptoms usually come on soon after eating or drinking, but there can sometimes be a delay between eating and developing indigestion.

You can get symptoms at any point during your pregnancy, but they are more common from 27 weeks onwards.

Things you can do to help with indigestion and heartburn

Changes to your diet and lifestyle may be enough to control your symptoms, particularly if they are mild.

Eat healthily

You're more likely to get indigestion if you're very full.

If you're pregnant, it may be tempting to eat more than you would normally, but this may not be good for you or your baby.

Change your eating and drinking habits

You may be able to control your indigestion with changes to your eating habits.

It can help to eat small meals often, rather than larger meals 3 times a day, and to not eat within 3 hours of going to bed at night.

Cutting down on drinks containing caffeine, and foods that are rich, spicy or fatty, can also ease symptoms.

Keep upright

Sit up straight when you eat. This will take the pressure off your stomach. Propping your head and shoulders up when you go to bed can stop stomach acid coming up while you sleep.

Stop smoking

Smoking when pregnant can cause indigestion, and can seriously affect the health of you and your unborn baby.

When you smoke, the chemicals you inhale can contribute to your indigestion. These chemicals can cause the ring of muscle at the lower end of your gullet to relax, which allows stomach acid to come back up more easily. This is known as acid reflux.

Smoking also increases the risk of:

• your baby being born prematurely (before week 37 of your pregnancy)
• your baby being born with a low birthweight
• sudden infant death syndrome (SIDS), or "cot death"

There's lots of help available to stop smoking. Talk to your midwife or call the NHS Smokefree helpline on 0300 123 1044. Find out more about stopping smoking in pregnancy.

Avoid alcohol

Drinking alcohol can cause indigestion. During pregnancy, it can also lead to long-term harm to the baby. It's safest to not drink alcohol at all in pregnancy.

When to get medical help

See your midwife or GP if you need help managing your symptoms or if changes to your diet and lifestyle do not work. They may recommend medicine to ease your symptoms.

You should also see your midwife or GP if you have any of the following:

• difficulty eating or keeping food down
• weight loss
• stomach pains

Your midwife or GP may ask about your symptoms and examine you by pressing gently on different areas of your chest and stomach to see whether it's painful.

If you're taking prescription medicines

Speak to your GP if you're taking medicine for another condition, such as antidepressants, and you think it may be making your indigestion worse. They may be able to prescribe an alternative medicine.

Never stop taking a prescribed medicine unless you're advised to do so by your GP or another qualified healthcare professional who's responsible for your care.

Medicines for indigestion and heartburn

Medicines for indigestion and heartburn during pregnancy include:

• antacids – to neutralise the acid in your stomach (some are available over the counter from a pharmacist)
• alginates – to relieve indigestion caused by acid reflux by stopping the acid in your stomach coming back up your gullet

You may only need to take antacids and alginates when you start getting symptoms. However, your GP may recommend taking them before symptoms come on – for example, before a meal or before bed.

If you're taking iron supplements as well as antacids, do not take them at the same time. Antacids can stop iron from being absorbed by your body.

If antacids and alginates do not improve your symptoms, your GP may prescribe a medicine to reduce the amount of acid in your stomach. 2 that are widely used in pregnancy and not known to be harmful to an unborn baby are:

• ranitidine – a tablet you take twice a day
• omeprazole – a tablet you take once a day

Causes of indigestion in pregnancy

Symptoms of indigestion come when the acid in your stomach irritates your stomach lining or your gullet. This causes pain and a burning feeling.

When you're pregnant, you're more likely to have indigestion because of:

• hormonal changes
• the growing baby pressing on your stomach
• the muscles between your stomach and gullet relaxing, allowing stomach acid to come back up

You may be more likely to get indigestion in pregnancy if:

• you had indigestion before you were pregnant
• you've been pregnant before
• you're in the later stages of pregnancy

Pregnancy Heartburn? 7 Ways to Get Relief

Expectant mothers everywhere are aching to know one thing: “How can I get some relief from this awful pregnancy heartburn?”

To help ease your pain, here are some answers to your “burning” questions. (Pardon the pun.)

When you’re growing a human being, you don’t have time for that yucky acid reflux. But your usual go-to methods for treating it may not be safe for your unborn baby. (Remember Pepto Bismol? That’s on the No Fly List for moms-to-be, according to FDA recommendations.)

Instead, here are some of the safest and best ways to get rid of heartburn when you’re pregnant:

1. Dip into some yogurt. Its probiotics and soothing texture make yogurt a great option for extinguishing heartburn – or at least dousing the flames a little.
2. Drink milk with honey. According to the American Pregnancy Association, a tablespoon of honey mixed in a glass of warm milk may be just what you need to neutralize heartburn-causing acid.
3. Snack on almonds. Munching on a handful of almonds may provide heartburn relief since these nuts have a lower acidity level than others.
4. Eat pineapple or papaya. For some women, the digestive enzymes in pineapple and papaya have helped ease symptoms. Eating these fruits after your meals can aid digestion and reduce your chances of heartburn.
5. Try a little ginger. You probably knew ginger was a good remedy for an upset stomach. Well, that makes it a helpful candidate for fighting off heartburn, too. Among ginger’s many benefits, it can reduce inflammation and prevent stomach acid from traveling up the esophagus. 
6. Chew sugar-free gum. Another effective method for taming the burn is to chew some sugar-free gum. One study found that chewing sugar-free gum for 30 minutes after a meal can reduce acid reflux.
7. Take (doctor-approved) medication. When all else fails, certain medications are considered safe to use for pregnancy heartburn relief. Just make sure you speak to your doctor or OB-GYN first. If your heartburn is severe, they may prescribe special medication to help control it.

While not every tip mentioned above may work to ease your symptoms, you’ve got nine months to try them all and figure out what works.

It’s important to be extremely careful about the medications you take when pregnant.

For heartburn relief, over-the-counter antacids (such as Tums, Mylanta, Rolaids, and Maalox) are all considered safe medications to use during pregnancy. 

As always, consult with your provider about any medications you’re taking – even if they’re considered safe. (This is especially true for high-risk pregnancies.) 

If you experience any unusual symptoms while taking an over-the-counter medication, call your doctor immediately. 

They say prevention is the best medicine, so knowing common heartburn triggers can help you keep the acid at bay.

Of course, pregnancy itself is a major trigger for heartburn. As your growing uterus puts pressure on your stomach, this pushes stomach acid up your throat. 

Those lovely hormones are no help either. They tend to relax the valve between your stomach and esophagus, which makes it easier for acid to make its way upward.

While there’s nothing you can do to stop this entirely, there are a few things that can help prevent heartburn from flaring up during pregnancy:

• Avoid lying down after eating. It may be tempting to take a post-meal nap, but if you want to prevent heartburn, don’t lie down after eating. Consider napping in an upright recliner instead.
• Prop yourself up at night. It’s hard enough to sleep well while pregnant without throwing acid reflux on top of everything. To prevent nighttime heartburn, try propping yourself up when you go to sleep to counteract the acid.
• Don’t eat before bedtime. In addition to propping yourself up at night, try not to eat anything within three hours of hitting the sack.
• Skip spicy, acidic, or fried foods. Ask yourself: Are those greasy chips worth being doubled over in pain later? (Probably not. ) If you want to avoid the risk, steer clear of any and all rich, fatty foods. Not only will this help prevent heartburn, but making more nutritious choices helps ensure that you your baby is getting the important vitamins and minerals that they need to stay healthy in utero.
  
• Eat small meals, but more frequently. Your pregnant tummy doesn’t love to be hit with large amounts of food to digest in one go. Make things easier on your gut by eating several small meals throughout the day instead of three large ones.
• Eat slowly. Wolfing down those small meals will defeat the purpose of spreading them out. Eating quickly increases the risk of acid reflux, so slow down and enjoy your food.
• Wear loose clothing. Tight-fitting clothes are not your stomach’s best friend when you’re trying to prevent heartburn – particularly during pregnancy. Wear clothing that offers support without being restrictive. 
• Drink your liquids between meals. If you’re the type of person who likes to take a swig of their drink between each bite, it’s time to change course. Drinking liquids during meals can exacerbate heartburn symptoms, so take little sips if you’re thirsty at mealtime. 

Someday, scientists may very well invent a miracle medication that promises permanent pregnancy heartburn relief. Unfortunately, that hasn’t happened yet.

So, if you’re wondering how long you can expect to deal with heartburn while you’re pregnant, it will probably be throughout your entire pregnancy. (Now may be a good time to remind yourself that you get a cute little baby out of this when you’re done.)

However, just because there’s no cure, that doesn’t mean you can’t find some relief in the meantime. 

If severe pregnancy heartburn is getting in the way of everyday life, it’s time to see a doctor.
