I’m Pregnant and My Farts Smell Like Rotten Eggs

If you’re pregnant and find your farts smelling like rotten eggs, you’re not alone. Bloating and constipation, typical pregnancy issues, may lead to increased gas, potentially intensifying its odor. Let’s explore the causes of these unpleasantly smelly pregnancy farts and suggest ways to reduce their odor.

Pregnancy and Rotten Egg Farts: The Causes

1. Hormonal Changes

During the first trimester of pregnancy, hormonal changes occur. The production of hormones like progesterone and estrogen increases to prepare your uterus for the fetus. This hormonal shift relaxes the muscles, including those in your digestive tract, slowing down the digestion process leading to bloats and gases. Increased estrogen levels can also cause your body to retain water and gas, resulting in rotten egg-smelling farts.

2. Stretching Stomach

As your tummy expands to accommodate the growing fetus, it applies pressure on your stomach, resulting in gas. When gas builds up for a longer time, the smell can intensify, emitting a foul, rotten odor. Light exercises can help alleviate gas build-up.

3. Diet During Pregnancy

Certain foods can enhance gas production during pregnancy. Spices, dairy products, oily foods, and some gas-inducing vegetables can disturb your digestive tract. Foods rich in fiber, while generally beneficial, can slow your digestion process, leading to gases that can smell like rotten eggs over time. Reducing high-fiber foods can help fight the gases.

4. Eating Too Quickly

Eating too quickly without thoroughly chewing your food can slow digestion. Also, hurried eating can cause you to swallow air, which later disrupts your stomach. Eating slowly can prevent foul-smelling gas.

5. Pregnancy-related Constipation

Changes in hormones during pregnancy can slow down the excretion process, leading to constipation. Increased water intake can help alleviate constipation.

6. Bacteria in the Digestive System

A slow digestion process can increase the number of bacteria in your colon, leading to infections. These bacterial infections can increase the number of gases emitted from your bowels, which come with a bad smell.

Minimizing Smelly Farts During Pregnancy

Here are a few strategies to reduce smelly farts during pregnancy:

  1. Eat a balanced diet: A diet rich in fruits, vegetables, and whole grains can reduce fart odor. Avoid foods high in sulfur such as meats, cheese, and certain vegetables.
  2. Stay hydrated: Consuming plenty of water can lessen the smell of your farts.
  3. Eat slowly and chew thoroughly: Proper digestion begins in the mouth. Thorough chewing can decrease gas production in the digestive system.
  4. Avoid swallowing air: Swallowing air can contribute to excess gas. Prevent this by avoiding straws, hard candies, and eating too quickly.
  5. Use over-the-counter remedies: Certain remedies can reduce gas and bloating. Always consult with your healthcare provider before using any new medications during pregnancy.

Is the Fart Smell a Predictor of Baby’s Gender?

There’s no scientific evidence that foul-smelling farts during pregnancy can predict your baby’s gender. The smell of farts is influenced by various factors, including your diet and gut bacteria, not the gender of your baby.

Are Farts That Smell Like Rotten Eggs Healthy?

In general, smelly farts are nothing to worry about. They are a natural part of digestion and are often caused by the foods you eat and the bacteria in your gut. However, if you notice a sudden change in the smell of your farts, or if they are accompanied by other symptoms such as pain, it might be a good idea to talk to your healthcare provider.

How Do You Get Rid of Smelly Farts When Pregnant?

Here are a few strategies to help reduce the smell of your farts during pregnancy:

1. Adjust Your Diet

Eating a balanced diet rich in fruits, vegetables, and whole grains can help reduce the smell of your farts. Try to limit foods high in sulfur, which can contribute to the smell.

2. Stay Hydrated

Drinking plenty of water can help reduce the smell of your farts. It aids in digestion and can help to flush toxins out of your body.

3. Eat Slowly and Chew Your Food Well

Proper digestion begins in the mouth, so taking your time to chew your food thoroughly can help reduce the amount of gas you produce.

4. Avoid Swallowing Air

Swallowing air can lead to excess gas. Avoid habits that can cause you to swallow air, such as drinking through a straw or eating too quickly.

5. Use Over-The-Counter Remedies

There are over-the-counter remedies that can help reduce gas and bloating, such as simethicone (Gas-X) and activated charcoal. Be sure to check with your healthcare provider before starting any new medications during pregnancy.


Experiencing smelly farts during pregnancy, reminiscent of rotten eggs, can be unpleasant but is typically normal. Checking your diet, eating slower, and reducing foods that increase constipation can help. Consuming lots of water and doing light exercises can also help in eliminating the bad smell.

While smelly farts during pregnancy can be embarrassing, they are generally normal and can be managed. Making a few simple changes to your diet and eating habits can help reduce the smell. As always, if you have any concerns, it’s a good idea to discuss them with your healthcare provider.
