Bad breath is not something that is discussed in a group setting (well, maybe it is for health professionals), but it is a common condition that many people have to deal with – even though they don’t want to talk about it.

Bad breath, also known as halitosis, can be embarrassing. However it is nothing to be embarrassed about.

There are many natural remedies for bad breath. These natural remedies work and you won’t feel self-conscious.

Bad breath, like other conditions, is often stigmatized.

It was assumed that bad breath meant poor hygiene. This is not true.

Bad breath, like any other health problem, can signal a deeper issue. Your mouth is part your upper GI tract so bad breath can be a sign of underlying health issues.

You may have occasional bad breath, or you have chronic halitosis that causes an unpleasant odor. Here are some common causes and natural remedies to get rid of bad breath.

Poor dental hygiene can lead to odor-causing bacteria. To prevent food particles from building up and attract bacteria, it’s essential to floss every day and brush your teeth after each meal.

Even those with impeccable oral hygiene can still have bad breath.

These are some causes of bad breath that do not have to do with oral hygiene.

A Weakened Digestive System

Your stomach, esophagus and mouth are all part of your upper GI tract. It makes sense that if your digestive tract isn’t working optimally, which means that food isn’t being properly absorbed, there’s a possibility that bacteria that causes odors can remain in your system.

This will allow bad breath to escape your mouth.

Bad breath isn’t necessarily the most beautiful picture.

Understanding how bad breath can be caused by a weak digestive system will help you to find natural ways to get rid of it. 

There are many factors that can lead to a weak digestive system, including frequent antibiotic use, high intake of refined sugars and processed foods, chronic stress, and frequent alcohol consumption.

A Diet High in Animal Products

A common misconception about diets is that you need to consume a lot of animal protein in order to be healthy.

All plant foods, including fruits and veggies, contain amino acids. However, we tend to overdo this with animal protein, especially when we want to build muscle.

Bad breath can be linked to an excess intake of animal protein.

First, animal products can take longer for your body to digest. The odor-causing bacteria might take longer to ferment undigested food before it passes through your body.

Acidifying animal protein can also promote the growth of bad bacteria.

There’s nothing wrong in consuming high-quality animal proteins on occasion. Bad breath can be caused by eating animal protein every meal.

Low stomach acid

Bad breath is caused by low stomach acid. Your body needs sufficient stomach acid to digest food properly and kill harmful pathogens.

Insufficient stomach acid can allow bacteria that causes odors to thrive and cause more serious infections.

Low stomach acid is a problem that many people have to deal with today. This is because of chronic stress, antibiotic use and high-sugar diets. Low stomach acid could be the cause of bad breath, bloating, and acid reflux.

Certain foods: Garlic, Onion and Spices.

Bad breath can be caused by eating garlic cloves. However, bad breath can also result from other foods like onions, spices and coffee.

Although cigarettes are not considered food, they can cause halitosis due to their strong chemical odor. Cigarettes can also cause bad breath by acidifying the body.

GI Tract Infections: GERD, H.Pylori

Low stomach acid can lead to GERD (gastroesophageal reflux disease), and H.Pylori (haute palatine syndrome). This can cause bad breath.

H.Pylori and GERD can cause a decrease in the body’s ability for food to be properly digested. This promotes the growth odor-causing bacteria.


Side effects can occur with prescription medications, including bad breath.

Prescription medications and antibiotics are effective in killing bad bacteria. However, they can also kill the friendly bacteria.

The bad bacteria that causes odors can thrive if there is not enough good bacteria.

Bad breath is more common with certain medications than others.
