Heartburn during pregnancy

What causes heartburn
DURING PREGNANCY?

A couple wondering when does heartburn start in pregnancy.

Heartburn is very common during pregnancy especially during the third trimester. Heartburn during early pregnancy (first trimester) affects 22% of women, 39% in the second trimester and 72% in the last.18 But what are the reasons for heartburn during pregnancy? Your body produces hormones that can slow down digestion and can cause the muscular valve between the oesophagus and the stomach to relax.

As a result, stomach acid is more likely to leak into the oesophagus and cause a burning pain in the chest and throat. The increasing pressure on your stomach as your baby grows can also force the acid into the oesophagus.

Don’t worry, it does not harm the baby, but it can be extremely uncomfortable. Pregnancy heartburn remedies include Rennie which can be taken during pregnancy as long as it is taken according to the instructions*.

*Medicines can affect the unborn baby. Always talk to your doctor or pharmacist before taking any medicine in pregnancy.

What can I take for heartburn during pregnancy?

You’ll be relieved to know that Rennie chewable tablets (Spearmint, Peppermint and Orange) are suitable for use during pregnancy (if taken as instructed and if prolonged intake of high dosages is avoided). Rennie’s antacid-based calcium carbonate and magnesium carbonate formula acts physically rather than by entering the bloodstream, neutralising excess acid and turning it into water and other natural substances10 that are easily evacuated by the body.

Always talk to your doctor or pharmacist before taking any medicine during pregnancy. Always read the label. If symptoms are severe or prolonged, talk to your doctor or pharmacist.

Tips for avoiding
HEARTBURN DURING PREGNANCY

How and what you eat can help keep heartburn to a minimum in pregnancy:

  • Avoid food that cause acid reflux.
  • Eating your meals too quickly increases the likelihood of heartburn. Try to relax and enjoy your food.
  • Try eating five or six smaller meals rather than three large ones, which are hours apart, to prevent your stomach from becoming too full and pushing up under your diaphragm. If small meals don’t work for you, try to eat your main meal at lunchtime and your evening meal as early as possible. This will allow plenty of time for food to pass down through the stomach and minimise the risk of acid reflux before bedtime.
  • Try to not eat before bed and stay sitting upright after eating, as lying down can allow food and stomach acid to be regurgitated. Sleeping propped up by two or three pillows may also help in the later stages of pregnancy.
  • It’s not easy but keeping calm and avoiding stress can help keep your digestive system flowing smoothly.
  • Try not to drink lots of liquid when you eat as it dilutes your digestive juices making them less effective. Instead, stay hydrated by drinking water in between meals.
  • Unfortunately, even if you follow all advice on avoiding heartburn in pregnancy, you may still experience symptoms of indigestion which should disappear in most women after giving birth.
