Gut health expert busts five common myths about probiotics and digestion

Gut health has become one of the most talked-about health topics in recent years. From probiotic drinks and capsules to social media advice on “healing your gut,” people are paying more attention to digestion than ever before. Many believe that keeping the gut healthy can improve not only digestion but also immunity, energy and even mental health.

But along with this growing interest, many myths have also become popular. A lot of people follow advice without understanding the science behind it. According to gut health expert Dr Debojyoti Dhar, it is important to separate facts from myths and understand how the gut really works.

The gut microbiome is the collection of trillions of tiny living organisms inside our digestive system. These include bacteria, fungi and viruses that work together to keep the body healthy. They help digest food, absorb nutrients and support the immune system.

Dr Dhar says that many common beliefs about gut health are not fully correct. Here are five popular myths and the truth behind them.

Not all gut advice is true

The first myth is that everyone should take probiotics.

Probiotics are often sold as a simple answer for better digestion. Many people believe taking them daily will automatically improve gut health. But Dr Dhar says this is not true for everyone.

Each person has a different gut microbiome. This means the balance of bacteria inside your body is unique. A probiotic that works for one person may not work the same way for another.

For example, one person may feel better after taking probiotics, while another may see no change at all. This is because gut needs are different.

Experts say probiotics can be helpful in some cases, like after antibiotics or certain digestive problems, but they should not be treated as a magic solution for everyone.

The second myth is that all digestive problems are caused by food.

Food does affect digestion, but it is not the only reason behind stomach issues. Many people blame every digestive problem on what they ate, but Dr Dhar explains that there can be many other causes.

Stress is one big factor. When people are stressed, the gut can react strongly. This can cause bloating, stomach pain or constipation.

Lack of sleep can also affect digestion. Poor sleep can disturb the balance of gut bacteria.

Exercise is another important factor. Not moving enough can slow digestion.

Some medicines can also harm the gut microbiome. Antibiotics, painkillers and other drugs can change the gut’s natural balance.

So, focusing only on food may cause people to miss other important reasons behind their digestive troubles.

The third myth is that if you have no symptoms, your gut must be healthy.

This sounds logical, but it is not always true.

Dr Dhar says gut problems can sometimes grow quietly. A person may feel normal but still have an unhealthy gut balance.

This is because not every gut issue causes pain, gas or stomach discomfort right away. Some imbalances can stay hidden for a long time.

Research is now showing that these hidden imbalances may later affect immunity, metabolism and even mental health.

That is why experts say gut health is not only about symptoms. Regular healthy habits matter even when you feel fine.

Understanding your gut better

The fourth myth is that bacteria are bad.

For many years, people have linked bacteria with infections and diseases. This has made many think that bacteria inside the body should be removed.

But this is far from the truth.

Dr Dhar explains that the gut needs good bacteria to survive and function properly.

These good bacteria help break down food, absorb vitamins and minerals and keep harmful bacteria under control.

They also support the immune system, which protects the body from illness.

Without these helpful bacteria, digestion would become weak and the body would struggle to stay healthy.

So the goal is not to remove bacteria. The goal is to maintain a healthy balance.

The fifth myth is that the gut only contains bacteria.

When people hear the word “microbiome,” they mostly think about bacteria. But the gut is much more complex.

Dr Dhar says the gut is home to fungi, viruses and many other microorganisms too.

These tiny organisms live together and interact with each other in important ways.

They create a balance that supports digestion and overall health.

If this balance is disturbed, it can lead to problems like poor digestion, inflammation or weakness in the immune system.

Scientists are still studying how these microorganisms work together, and new discoveries are being made every year.

This shows that gut health is much more complicated than many people think.

Dr Dhar says that as science continues to grow, people should rely on facts instead of trends.

The main lesson is simple: gut health is personal.

There is no one diet, one probiotic or one quick fix that works for everyone.

Taking care of your gut means eating balanced meals, staying hydrated, sleeping well, managing stress and staying active.

Listening to your body is important, but so is understanding that not everything you hear online is true.

Good gut health is not about following every trend. It is about building healthy habits and understanding what your body truly needs.

As more research comes out, experts hope people will move away from myths and make smarter choices for their digestive health.
