Your gut is the entire digestive tract that runs from your esophagus to your rectum. It does more than just take in food and excrete food, however.

Experts refer to the gut as the second brain. The microbes and nerves in the gut can launch communication with the brain, affecting everything from hunger to mood.

If your gut is healthy, you have a proper balance of good and bad bacteria.

Your stomach secretes the right amount of acid to help process your food, and your liver and pancreas release the right enzymes to further digest your food.

The right balance of what you eat feeds your body. It also feeds the healthy bacteria in the gut that allow your food to be used effectively by the body.

If your gut is healthy, your body and mind probably are too.

You might think that the signs of an unhealthy gut would be obvious. Of course, symptoms like digestive distress, bowel movement problems, and abdominal pain can signal that something is unhealthy in your gut.

We’re not going to talk about the obvious: diarrhea and constipation.

However, other physical, emotional and mental warning signs can signal that your gut needs some serious TLC.

Here are 10 warning signs that you have an unhealthy gut and some tips for getting yourself back in balance.

1. Stress, Anxiety and Depression

The lining of your intestines is filled with nerves that contain similar tissue as the brain. These nerves communicate with the brain.

Your intestines also release the same feel-good neurotransmitters that are responsible for making you feel good. If your gut bacteria is in balance, you’re more likely to feel mentally balanced too.

2. You Get Sick a Lot

If you find that you catch every sniffle that goes around the office, all the vitamin C in the world may not help. According to the Gut Health Project, more than three-quarters of your immune system is found in your gastrointestinal tract.

A healthy microbiome, the balance of bacteria in your gut, produces healthy mucus that traps unwanted bacteria, viruses and toxins and helps remove them from the body.

Healthy mucus also allows your body to absorb the right vitamins and minerals to help support your immunity.

If your gut is unhealthy, thick, harmful mucus can help the wrong bugs thrive and limit your body’s ability to use vitamins and nutrients properly, leading to what may seem like constant sickness.

Next up on our list of warning signs you have an unhealthy gut is…

3. Skin Problems

Whether you have persistent acne, rosacea, eczema, dandruff or itchy, flaky skin, even the most intensive skincare routine may not fix the problem. That’s because your skin problems may be coming from your gut.

Skin experts refer to a gut-brain-skin axis that explains how gut health affects inflammation throughout the body, which in turn affects the skin (1).

Acne is something that I have personally struggled with for YEARS!  It was never so terrible that I needed to go to a doctor for it, but it was still constant and frustrating.

Only recently at 28 years old did I finally get it under control with a couple of things: Diet and Probiotics

I learned that while I loved nuts and have no serious adverse reactions to them, they do make me break out. Every time I eat them.

So I cut those out, and then finally kicked the rest of it when I cleaned up the rest of my diet and started taking probiotics again.  I had taken them regularly a few years ago, but I stopped for whatever reason at the time (and sorely wish I hadn’t!).

I can safely say that I will NOT stop taking them again anytime soon!

In fact, we have our own brand of Probiotics here at Avocadu called Gut-13.  You can read more about it at the end of this article.

4. Stubborn Weight

If you have trouble losing weight no matter what you do, it may be due to an unhealthy gut.

The bad news is that people who are overweight or obese have a different balance of intestinal bacteria than people who are at a healthy weight. The balance of microbes that you have from birth can set the stage for your weight throughout your life (2).

The good news is that as overweight people lose weight, their gut becomes more balanced. Taking a probiotics supplement has also been shown to help with weight loss.

5. Autoimmune Disease

Gut health has been linked to autoimmune disease.

Although experts aren’t sure exactly what causes autoimmune diseases like rheumatoid arthritis, Crohn’s disease, and lupus, they do know that they occur when your immune system attacks its own healthy cells.

6. Acid Reflux

Frequent, unrelenting acid reflux is often caused by an unhealthy gut.

This may explain why nothing seems to help your constant heartburn.

Acid reflux, bloating, and burping are often caused by a buildup of unhealthy bacteria in the GI tract and stomach.

Acid-reducing medications can actually help this bacteria thrive (3).  Normally, stomach acid kills the bad bacteria.

If you’re always neutralizing your stomach acid, however, you’re letting that bad bacteria grow.

7. Yeast Infections

Yeast can grow out of control when your system is imbalanced. The imbalance in the gut can show up as digestive issues, fungal infections of the skin, constant fatigue or even fibromyalgia.

This can also cause a condition known as candida.

8. Lack of Energy

If you find it hard to dredge up any energy even when you’ve had enough sleep, you may have an unhealthy gut.

An unhealthy balance of bacteria in the gut can prevent your body from absorbing the nutrients it needs from foods, leaving you tired all the time.

An unhealthy gut can also be permeable, meaning that it lets in toxins through the intestinal walls. These unhealthy chemicals can also affect your energy levels.

9. High Cholesterol and Triglycerides

Your gut microbes may also influence your heart health. There are 34 microorganisms in the digestive tract that can influence the levels of fat in your blood.

Researchers are also starting to find links between HDL, “good” cholesterol, and a higher biodiversity of gut bacteria.

10. Asthma

If you have asthma, it might have been caused by the balance of bacteria that you had in your gut around the time of birth, according to this Time article (4).

Dr. Hyman explains that balancing your gut can help improve asthma symptoms.

How Can You Build a Healthy Gut?

You might want to know what to do about your unhealthy gut. Maintaining a healthy gut involves making consistent healthy lifestyle choices, such as the following:

  • Eat whole, nutrient-rich foods – Eating a variety of clean, colorful foods provides your body with the nutrients that it needs to operate properly. Chemically processed foods often contain compounds that feed the bad bacteria and cause imbalance.
  • Eat less sugar – Sugar is another culprit that feeds the unhealthy bacteria. Eliminating it from your diet can help rebalance your intestinal microbiome.
  • Chew your food – When you don’t chew your food well enough, it doesn’t do what it’s supposed to in order to feed the healthy bacteria and promote healthy digestion.
  • Stay hydrated – Water is necessary for just about every bodily function, including maintaining a healthy gut.
  • Detox – Following a gentle detoxification program can eliminate many of the factors that are causing inflammation on a daily basis, giving your gut a chance to heal and rebalance itself.
  • Drink apple cider vinegar – Adding a tablespoon or two of apple cider vinegar to a glass of water can boost the amount of acid in your stomach, helping your digestion to function properly.
  • Consume more probiotics – Eating fermented foods or taking probiotic supplements can help restore the balance in your gut.

Taking a good probiotic is the first place to start, whether you make any of the above changes or not. It will take time to heal your gut, so adding in a probiotic AND making some or all of the above changes is the quickest way to reboot your system.

No matter what supplement you use, you should take AT LEAST 50 billion units of probiotics daily from a minimum of 10 different sources for best results.

While you don’t need to purchase only refrigerated probiotics, make sure the packaging is well sealed. It’s also essential that the packaging is dark (or opaque, not transparent) to protect from light damage.

We have our own brand of Probiotics at Avocadu called Gut-13.

Our specially formulated probiotic supplement contains:

  • Over 100 Million CFU’s Per Serving
  • 13 Different Gut Healing Strains
  • Delayed-Release for Deeper Support
  • Made in the USA 

You can read more about it and why it’s so important for not only gut health but overall health on our probiotics page.

Probiotics are one of the best solutions for healing your gut, helping you lose weight faster, and providing you with a healthy source of gut flora every day!

Next, you will need to eat a healthy diet full of whole, natural foods!

Probiotics will help to get your gut started on the right track again, but it won’t make a very big impact if you are still eating a diet full of the WRONG foods that wreak havoc on your gut in the first place.

This is a big emphasis of our 21-Day Fat Loss Challenge as it’s about changing our eating habits and re-learning what we should and should not be eating.

People lose an average of 10-21 pounds in 21 days and absolutely love it!  But even better than the weight loss is the feedback we get from people about how the program has taught them how to change their eating habits and find a diet that truly works for them in the long-term.

Hi! Awesome video!! I am suffering from persistent acne that is quite severe I would say, and I am currently in the process of healing my gut. I’m taking a probiotic as well as L-glutamine, along with eating gut-healing foods. While healing the gut and doing these things, is it important to stop eating the foods that I am sensitive to all together? Nuts and eggs do not do well with me right now. Is it necessary to stop eating them for maybe a few months or so while healing the gut and then eating them again? Or is it okay to still eat those foods during the healing process? Thanks!

Hey Kate! If you know that you have sensitivities to certain foods, you really shouldn’t eat them at all. That is your body letting you know that it doesn’t agree with something in those foods. You should focus on getting your nutrients elsewhere in a way that your body agrees with. I actually have sensitivities to both of those foods as well. Now that my gut is healed, I can eat nuts sparingly and now show any adverse signs. I still avoid them at all costs though, because I choose to eat foods that I know that my body agrees with. I can eat eggs every day, but eating them in excess (more than 3 a day or so) makes my skin break out. I have no issues when I eat 2/day though, so that is what I stick with. I would remove them from your diet until your gut health is in better shape and then try to reintroduce. Only continue to eat them if you don’t show ANY adverse effects though! Hope that helps! 🙂

Yes, that helped, thank you!! I noticed you mentioned having acne in the video; would you say that removing those foods from your diet (and of course healing your gut) really made the difference for complete skin healing? Because like you, my diet is super clean and I don’t eat any dairy, gluten, soy, or processed foods. It has helped my skin some and many other areas of my health, but it’s still just frustrating that my skin is still so bad. But, I honestly think it may be my gut because I have all of the symptoms to the max. So, hopefully healing my gut will finally clear it!!

Yes, it was the combination of healing my gut combined with identifying the foods that I have problems with. Again, cut out ANY and ALL foods that you KNOW for certain give you an insensitivity. Do you ever eat bad foods (dairy, processed, etc.) once a week while in a social setting or as a treat? Even eating it only once/week can cause issues. It was only when I spent a month living in Bali and ate an elimination diet of sorts did I actually figure out what my problems were. I went 4 weeks without alcohol, sugar, or any processed foods, because they weren’t readily available in Ubud, and my skin looked AMAZING afterwards. I call it my “Bali diet,” because I revert back to it whenever my skin freaks out and I need to identify a new food that could be causing it. We don’t have an elimination diet on Avocadu per se, although our 21-Day Fat Loss Challenge is pretty darn close. So you could try that one out or try “googling” elimination diets. Just know that you have to give it at LEAST 3-4 weeks of strict dieting without ANY cheat meals, foods, or slip ups! If you want to figure out the FASTEST way to cure it all, I would combine a diet like that with probiotics to help heal your gut.

Hi! Awesome video! I am suffering from severe, persistent acne and I am now in the process of healing my gut. I’m taking probiotics, L-glutamine, and eating gut-healing foods. Do I need to stop eating the foods that I am sensitive too during the healing process? Like for a few months? Eggs and nuts, especially nuts, do not do well with me right now. So, is it necessary that I stop eating these until my gut is healed? Thanks!
