Natural Remedies for Pregnancy Heartburn (That Are Actually Safe to Try)

Somewhere around the second trimester, a lot of women discover a whole new relationship with heartburn. If you’re after natural remedies for pregnancy heartburn that don’t involve reaching for antacids every night, there are some genuinely useful options, but the right one depends on what’s actually driving yours.

Why Heartburn Gets Worse as Pregnancy Progresses

Progesterone relaxes the valve between your stomach and oesophagus, which makes it easier for stomach acid to travel back up. Later in pregnancy, your growing uterus adds physical pressure on top of that. It’s a frustrating combination, but an explainable one.

Not All Pregnancy Heartburn Is the Same

Most pregnancy heartburn is a “too much acid, too little room” problem, and that’s what most remedies (including this list) are aimed at. But in late pregnancy, some women have a different pattern: a stomach that feels cold and weak rather than hot and acidic. Digestion feels sluggish, food sits heavily, and the usual acid-calming approach doesn’t help much. If that sounds more like you, warming rather than cooling foods and drinks tend to work better, and it’s worth mentioning this distinction to your practitioner rather than assuming one heartburn remedy fits all.

Natural Remedies for Pregnancy Heartburn

Slippery elm and marshmallow root. Both are demulcent herbs, meaning they coat and soothe the digestive lining. They’re generally considered pregnancy-safe, though getting the right form matters, marshmallow root in particular needs to be cold-extracted to preserve its soothing properties, so check with your clinical herbalist or care provider on sourcing and dose.

Ginger tea. As well as helping nausea, ginger can settle the stomach for some women with reflux, though a small number find it worsens their symptoms, so pay attention to how you respond.

Warming foods for the “cold, weak gut” pattern. If your digestion feels sluggish rather than acidic, warm, well-cooked meals, miso in hot water, or a little umeboshi paste can be more settling than anything cold or raw. Slow-cooked, easily digestible meals also tend to sit better than a big steak or a cold smoothie in this pattern.

Smaller, more frequent meals. A very full stomach has nowhere to go but up. Eating less at each sitting tends to reduce symptoms.

Stay upright after eating. Avoid lying down for at least an hour after meals, and prop yourself up with extra pillows at night.

A handful of plain almonds. An old but genuinely useful trick, the fats and texture can help settle acid.

What to Avoid

Spicy, fatty, and acidic foods are common triggers, as is eating too close to bedtime. It’s worth keeping a rough note of what tends to set yours off, since triggers are quite individual, and quite different depending on which pattern above sounds like you.

When to See Your GP, Midwife, or Obstetrician

If heartburn is severe, constant, or affecting your ability to eat and sleep, there are pregnancy-safe medical options too, and your GP or obstetrician can talk you through them alongside anything natural you’re trying.
