A guide to the pregnant gut


No one really tells you what to expect during pregnancy. Symptoms sneak up on you and you start wondering if you’re supposed to feel this way or not. And as far as the gut is concerned, it goes through a ton of changes during pregnancy- especially in the motility and how it moves food and poop along. Let’s break down what to expect and why… and how to handle it. *Most importantly ALWAYS consult your doctor about any new symptoms and DO NOT take anything without their blessing*

1. Reflux (“GERD” or heartburn)
Up to 85% of women during pregnancy

Why? Decreased lower esophageal sphincter pressure due to hormones

Treatment (stepwise)

Lifestyle/nutrition: elevate the head end of the bed, don’t eat 2-3 hours before going to sleep (especially fatty meals), avoid dietary triggers (keep a food diary!), diaphragmatic breathing (find details on my site under conditions —> GERD)

Antacids (avoid sodium bicarbonate & and magnesium triplicate) ex. TUMS

Sucralfate (Carafate) 1 g orally three times daily

Histamine 2 receptor antagonists (H2RAs)- Ranitidine or Cimetidine have the most evidence

2. Nausea and vomiting
Up to 80% of women during pregnancy report nausea and 50% report vomiting

Why? Many reasons:

Hormonal changes: Increased estrogen and progesterone relax smooth muscle, slow gastrointestinal transit time and may alter gastric emptying. Increased hCG may play a role

Abnormal gastric motility

Helicobacter pylori infection

Genetic factors

Nutrient deficiencies (zinc, vitamin b6)

What to do?

Eat as soon as you feel hungry to avoid an empty stomach, which can worsen nausea. Snack often!

Eat slowly and in small amounts every 1-2 hours to avoid over filling your stomach

Avoid foods high in sugar

Keep a food diary- some trigger foods include coffee or foods that are spicy, smelly, high fat, acidic or sweet

Focus on protein-rich meals and snacks

Peppermint tea

Drink fluids at least 30 minutes before or after food to avoid a full stomach- best if cold, clear, carbonated or sour (ex. ginger ale, lemonade, popsicles) and small amounts, try using a straw

Avoid environmental triggers: perfume, smoke, humidity… keep a trigger/symptom diary!

Take prenatal vitamins before bed with a snack instead of the morning on an empty stomach

Ginger! Ginger significantly improved the symptoms of nausea when compared to placebo (MD 1.20, 95% CI 0.56-1.84, p = 0.0002, I² = 0%), Best is to buy fresh finger and make your own tea, add to foods, sauces, drinks

Pyridoxine (vitamin b6)

Acupuncture and acupressure: p6 wristbands

Hypnosis

3. Bloating & Constipation
Up to 39% of pregnant women report constipation

Why? Hormonal changes affect small bowel and colon motility. Increased progesterone decreases the activity of colon movement. Motilin also decreases during pregnancy which usually stimulates the gut to move. In addition, the gravid uterus with baby can press against the small bowel and decrease movement. Other factors may also play a role like iron supplements and bed-rest.

What to do

Increase dietary fiber

Increase fluids, at least 3 liters of water a day

Try fiber supplementation, ex. Benefiber

Avoid carbonated beverages, fake sugars, processed food, dairy

Consider Feriva if you need a non-constipating iron supplement

4. Hemorrhoids
Up to 40% of pregnant women are affected by hemorrhoids

Why? Hemorrhoids are veins in the anal canal that grow with increased venous pressure in pregnancy and constipation/diarrhea, which causes itching, pain and bleeding.

What to do?

Avoid constipation! See above

Hydrate, hydrate, hydrate. At LEAST 3 liters of water a day

Increase dietary fiber

Try Calmol-4 suppositories. Made of just zinc oxide & cocoa butter- SO soothing. Also great for anal fissures.

And don’t forget to enrich your microbiome before your baby arrives!
This is a critical development window! Massive bacterial colonization of the newborn gut occurs during labor and vaginal delivery when the baby is exposed to the maternal vagina, feces and skin microbiota. This exposure ultimately plays an important role in the predisposition of your child to chronic inflammation! So make sure to nourish and diversify your gut microbiome during pregnancy and even before- to ensure your child gets the building blocks for a strong microbiome!
