7 Reasons You Probably Have an Unhealthy Gut (+ 5 Ways to Improve Gut Health)

You rely on your immune system to protect you from infections and keep you healthy … and here’s where gut health comes in.

Every day, pathogens — like infectious bacteria, viruses and toxins — threaten your health. Your immune system has special cells that patrol constantly so they can detect those pathogens immediately.

Once your immune system sees what it’s up against, it responds with powerful weapons to defeat the threat before it affects your health.

When it’s working properly, that is.

Your immune system can’t function properly — or fully protect you — without the support of good bacteria in your gut. Unfortunately, it doesn’t take much to throw your gut bacteria out of balance and sabotage your immune system and gut health.

Your immune system relies on gut health

Your gut microbiome contains trillions of bacteria, both good and bad. When your gut microbiome has a healthy balance, good bacteria (probiotics) outnumber bad bacteria (pathogens) and contribute to your overall well-being.

The probiotic bacteria in your gut help shape and train your immune system and supply it with supportive nutrients and healing compounds. Since more than 70 percent of your immune system resides in your gut, you can see why healthy balance is so important.

When your gut microbiome falls out of balance and into a state of dysbiosis, bad bacteria outnumber good bacteria. When that happens, your gut microbiome has a negative impact on your immune system and can contribute to issues like leaky gut.

Dysbiosis can lead your immune system to overreact, creating inflammation and attacking your own healthy cells. It can also cause an immune system under-reaction, which leaves you extra vulnerable to any infections that are going around.

Unfortunately, your gut microbiome faces damaging threats every day. Any one of those threats can sabotage gut balance … and healthy immune system function.

Gut health disruptors

Gut dysbiosis damages your immune system and the way it responds to infections. That’s why it’s crucial to get your gut microbiome in healthy balance and keep it there.

Many features of everyday life work against a healthy gut microbiome and immune system, leaving you extra vulnerable to infections. Some of the worst culprits include:

1. Antibiotics and other medications – including proton pump inhibitors, beta-blockers and antidepressants – can cause dysbiosis, sometimes after a single dose.
2. Pesticides, including glyphosate, can kill beneficial gut bacteria, allowing bad bacteria to dominate the microbiome.
3. Ultra-processed foods full of sugar and unhealthy fats encourage pathogen overgrowth and starve out probiotic bacteria, which naturally thrive on prebiotic fiber.
4. Stress and anxiety negatively affect your gut microbiome through a two-way path known as the gut-brain axis. Emotional stress can cause dysbiosis, and dysbiosis can increase emotional stress, leaving you trapped in a damaging feedback loop.
5. Environmental toxins, including household cleaners and heavy metals, negatively change the makeup and function of the gut microbiome, leading to increased risk of disease.
6. Sedentary lifestyle leads to increased populations of pathogenic gut bacteria and lower diversity in the gut microbiome, contributing to increased risk of chronic diseases and infections.
7. Lack of sleep and poor sleep quality can cause dysbiosis, leading to a weakened immune system.

Any of these factors can interfere with a healthy gut microbiome, but it’s even more likely that you experience several at once.

When your gut becomes unbalanced, it has an enormous effect on your immune system.

How gut imbalance upsets your immune system

Dysbiosis interferes with healthy immune system activity in a few different ways.

Harmful bacteria produce many damaging toxins, including lipopolysaccharides (LPS toxins). Both the bad bacteria and their toxic byproducts attack the protective lining — known as the gut barrier — inside the intestines.

The gut barrier’s job is to allow nutrients out into the bloodstream while keeping pathogens and toxins safely locked inside the gut.

When bad bacteria, LPS toxins and other harmful compounds attack, they damage the gut barrier and escape into the bloodstream. From there, they can reach any part of your body and do even more harm.

Your immune system detects these threats and starts to respond. It uses inflammation as one of its main defensive weapons.

Since new threats constantly leak through the gut barrier, your immune system can’t shut down its responses. That leads to system-wide, long-term inflammation — the root cause of many autoimmune and chronic conditions.

At the same time, the bad bacteria in the gut prevent good bacteria from flourishing.

Probiotic bacteria play a crucial role in optimal immune function by:

• Helping digest food completely and increasing nutrient absorption
• Producing essential nutrients, such as B vitamins and vitamin K
• Producing short-chain fatty acids (SCFAs) that help regulate immune cell function
• Creating anti-inflammatory compounds
• Protecting against pathogens
• Maintaining a strong gut barrier

In dysbiosis, when bad bacteria are in charge, your immune system loses out on all of that support.

The solution: Rebalance the gut microbiome so beneficial bacteria can flourish and get your immune system back on track.

Steps to fix a gut imbalance

You can rebalance an unhealthy gut and keep it in healthy shape by making five simple changes to your daily routine. Keep in mind that when considering how to improve gut health, you must achieve better balance between of the micro-organisms in your gut.

1. Detoxify your gut

In order for probiotic bacteria to survive, you need to remove the toxins that threaten them.

Using natural detox and cell-supporting agents — like clinically proven modified citrus pectin — can help your body get rid of toxins and other culprits that cause dysbiosis, while actively supporting gut health and protecting cell function.

2. Take probiotics

High-quality probiotics help restore an unhealthy gut back into balance. Giving your body a fresh supply of probiotics every day is a crucial part of keeping your gut — and your immune system — in harmony.

3. Nourish probiotics with prebiotics

Beneficial gut bacteria require a special diet made up of prebiotic fiber. Prebiotics sustain probiotics and allow them to produce healing compounds like SCFAs.

4. Eat a healthy diet

Sugary, fatty, processed foods harm your gut microbiome. Fresh, natural, whole foods provide the nutrients and fiber your gut needs to stay in healthy balance.

5. Exercise regularly

Moderate physical activity increases probiotic populations and enriches probiotic diversity. Exercising on most days improves your microbiome health — and your overall health as well.

When functioning at its best, your gut is an immune powerhouse. It also works hard to keep your neurological health in peak shape, while nourishing your body and removing toxins and waste.

The more we learn about the intricate connections between gut function, immunity and overall wellness, the more tools and strategies we have to improve this core foundation of optimal health.
