The Best Gut Health Test

Ombre’s Gut Health Test is an excellent choice for budget-conscious people who want value for their money.

What is the Gut?

You might think of your stomach when you hear the term gut, but this is only a part of your body’s gut.

The gut encompasses your entire gastrointestinal tract. It begins at the mouth and ends at the anus.

The gut is responsible for processing food. The process begins when you take a bite and ends when the waste that isn’t used is passed out as stool.

If the gut handles any part of the process inefficiently, it affects your overall health. This includes mental and emotional health.

Poor gut health also triggers symptoms including:

  • Abdominal pain
  • Bloating
  • Loose stools
  • Constipation
  • Heartburn
  • Nausea
  • Vomiting
  • Unexplained weight loss
  • Black stool
  • Fever
  • Trouble swallowing
  • Throat or chest pain
  • Jaundice

The gut’s microbiome includes everything in the gut’s environment. This includes microorganisms, bacteria, viruses, protozoa, and fungi, and their collective genetic material present in the gut.

All of these things play an important role in:

  • Nutrient and mineral absorption
  • Synthesis of enzymes, vitamins, and amino acids
  • Production of short-chain fatty acids (SCFAs)

What is Gut Health?

Gut health is the state of your gut microbiome and how they influence your overall health.

Gut health is a novel concept for most health enthusiasts. Some people feel they don't need to pay attention because they don't have any gastrointestinal issues.

But, this can be misleading. Most diseases that result from gut bacteria imbalance rarely show early signs. Some brain-related conditions such as fatigue, poor concentration and memory, stress, anxiety, and depression can all be symptoms of an unhealthy gut.

A healthy gut contains a healthy amount of the gut microbiome. These gut microbiomes promote lots of healthy body processes, right from infancy and throughout human life.

A lot of factors can affect gut health. They include:

  • Nutrition: The type of food you eat. Certain foods can affect your gut microflora, for better or for worse.
  • Use of Antibiotics: Some antibiotics can kill healthy gut bacteria and lead to an unhealthy gut.
  • Genetics: You can acquire either a healthy or unhealthy gut from your parents during conception.

“Plenty of the bad bacteria or too less of the good ones can cause your gut flora to be imbalanced. Your diet is really the first step toward achieving optimal gut balance,” says Dr. Dhingra.

How do you know there’s a problem with your gut’s microbiome?

If you experience any of the symptoms listed above, it could indicate a problem with gut health. But sometimes symptoms are subtle or you might have so many you aren’t sure exactly what is going on. In these cases, a microbiome test might help.

What a microbiome test can tell you

A gut microbiome test can reveal a variety of information about the status and health of your gut.

What can a microbiome test tell you?

  • The amount of good and bad bacteria or microorganisms present in your gut
  • What is causing any stomach symptoms you might experience
  • Which probiotics (either customized to you or over-the-counter) could help you

A microbiome test can also possibly improve skin, increase energy, improve sleep, and lose weight. This doesn't happen for everyone, but testing your gut bacteria can help you and give you information about what to improve on. 

What to look for in a microbiome testing kit

Health experts have varying opinions concerning the effectiveness of microbiome testing kits. Some recommend using more than one test and comparing the results to provide you with a more complete picture of your gut health.

It’s also important to review with your doctor any results you get from a test before making significant changes to improve your gut health.

If you decide to use an at-home microbiome test, look for tests that:

  • Search for and identify negative species in the gut that are linked to health problems
  • Share the scientific information supporting their testing procedures and conclusions
  • Measure the microbiome more than once, including before, during, and after a lifecycle change

Taking Care of Your Gut Microbiome

A variety of lifestyle and diet changes can help you improve your gut’s microbiome. In general, you want to promote a balanced gut and naturally improve its health.

How to Balance Your Gut Flora When There is Imbalance

Dr. Dhingra recommends a healthy and well-balanced diet.

“Stay away from processed foods and foods that are high in sugar. Instead, you should be eating more whole and unrefined foods rich in fiber, lean protein, and healthy fats.”

Healthy fats such as omega 3 fatty acids and monounsaturated fats reduce inflammation in the gut and encourage a healthy gut flora.

Other examples of foods that balance the gut microbiome include:

  • Whole grains
  • Fruits and vegetables
  • Lentils and nuts
  • Lean meats

How to Improve Gut Health Naturally

According to Dr. Dhingra, the best way to naturally improve gut health is to maintain a healthy lifestyle. This means having the right diet, getting quality sleep, having regular exercise, staying hydrated, and finding ways to reduce your stress.

You can also improve your gut health by:

  • Avoiding foods that damage gut health, such as fried foods, alcohol, caffeine, charred meats, artificial sweeteners, and high-fat foods
  • Switching to home cooking instead of frequently dining out
  • Stopping to eat as soon as you feel full
  • Avoiding self-medication with antibiotics, antacids, and painkillers
  • Limiting your alcohol intake

Having variety in your meals causes the gut flora to thrive. But you can also supplement your diet with probiotics and prebiotics, says Dr. Dhingra.

“Probiotics contain live bacteria that boost the “good” kind of bacteria in your gut. You can take them as supplements or by eating fermented foods. Some of these foods include kimchi, homemade yogurt, miso, sauerkraut, and tempeh.”

Medical experts have varying opinions concerning the effectiveness of probiotics, but if you choose to try one, opt for one that is from a reputable manufacturer that offers science-backed information about the product.

Dr. Dhingra adds it’s important that you include prebiotic foods to your diet. These are fiber-rich whole foods that provide sustenance to probiotics. Fruits, vegetables, beans, nuts, and seeds are all good sources of food for your gut microbiome.

Symptoms of a poor and unhealthy gut

How do you know you have an unhealthy gut? Most people take probiotics without having any known symptoms of an unhealthy gut.

This is not an entirely bad practice, but you could be wasting your money.

The good bacteria in your gut almost present no problems. They control important functions in your body and keep the bad bacteria in check. However, sometimes the bad bacteria can take over and dominate your gut.

This is where things go wrong.

When the bad bacteria take over, your gut sends a distress warning telling your body system that your gut is in bad shape. These signals usually translate to symptoms that are noticeable to most people.

Most symptoms of an unhealthy gut are usually familiar. They include:

  • Gas and Bloating
  • Diarrhoea
  • Constipation
  • Unusual cravings
  • Poor concentration and memory
  • Mood swings
  • Fatigue
  • Weight gain
  • Obesity
  • Autoimmune diseases

These symptoms are common to poor gut health. If you witness any one of the symptoms, it's necessary to consult your healthcare provider.

What if I find a problem?

How you deal with a gut health problem varies based on the severity of the problem. For instance, if you feel less-than-optimal and experience digestive symptoms like bloating or nausea, a few simple dietary changes can be enough to improve your gut’s microbiome.

If lifestyle and diet changes do not improve your symptoms, you should undergo a medical evaluation. It’s also important to seek medical attention if you have severe symptoms.

Long-term gut health problems put you at an increased risk of serious health issues. This includes colitis, colon polyps, cancer, and more. Many of these issues can be prevented or minimized by maintaining a healthy lifestyle, practicing good bowel habits, and getting screened for cancer.

Benefits of Good Gut Health

Since these bacteria influence lots of body processes, you will benefit from keeping them healthy.

These include:

  • Better food digestion
  • Improved mood
  • Improved concentration and focus
  • Improved immune system and disease prevention
  • Better sleep
  • Improved energy

These are the rewards of a healthy gut. It's necessary to undergo a gut test to know if your gut is healthy enough. This test will determine whether you need professional help or some lifestyle changes.
