Your gut is a powerful part of your digestion, immune system and mental health. When it is out of balance, your body has ways of letting you know that shouldn’t be ignored. Interpreting these signals and making some minor lifestyle changes can do wonders for your gut health.

Your gut is more than just a digestion system — it's integral to the health and vitality of your entire body. Known as the “second brain,” the gut affects immunity, metabolic factors, mental health and even hormones. You harbour trillions of microorganisms inside your digestive system, referred to collectively as the gut microbiome, which process food, absorb nutrients and shield your body from dangerous pathogens.

A smooth-running body results from a healthy gut. But when it’s not healthy, the signs can become much more unexpected — ranging from chronic fatigue and skin disorders to mood swings and weakened immunity. Most people tend to dismiss these early warning signs as insignificant or unrelated. But if ignored, bad gut health can silently lead to chronic inflammation, deficiency of nutrients and long-term health issues, says Dr. Kritika Malhotra, MD-Consultant Gastroenterologist & Gut Health Specialist

Modern lifestyles—stress, bad diet, sleep deprivation and over-reliance on antibiotics—meaning that gut problems are more common than ever. “Your gut is communicating with you all the time and giving clues if something’s not right. By learning to listen to your body's messages and practicing simple effective strategies, you can bring balance back, without beating up on your gut,” says the doctor.

The gut communicates with the rest of your body in many different ways and understanding what it is trying to tell you is critical to optimizing your overall health from the inside out.

Frequent Digestive Issues

Classic signs that your gut needs help include bloating, gas, constipation, diarrhoea and heartburn. These include symptoms of an imbalance of gut bacteria or trouble digesting some foods.

Constant Fatigue

You may be tired even when you’re getting enough sleep if your gut isn’t absorbing the nutrients it needs. If you gut health is not optimal, it can disrupt energy production and cause you to be perpetually tired.

Skin Problems

Many people with ailments like acne, eczema or unexplained rashes have an underlying inflammation and/or gut imbalance. What occurs in your gut often manifests on your skin.

Mood Changes and Brain Fog

Issues with the gut can have an impact on mental health –think anxiety, low mood and that inability to focus from what’s referred to as the ‘gut-brain connection’.

How to Improve Gut Health

Eat Gut-Friendly Foods

Add fiber-rich fruits, veggies, whole grains and fermented foods like curd and kefir which will feed the good bacteria.
