The gut is sometimes called the body’s “second brain” and for good reason. It is essential for digestion, nutrient uptake, mood and immune function. A robust gut contains more than a trillion bacteria, collectively known as the gut microbiome, that cooperate to keep the peace and aid in nearly every bodily process. But if that intricate system is thrown out of whack by junk food, stress, antibiotics or lack of sleep, the side effects can spin out into all kinds of health issues way beyond upset stomachs.

A bad gut can quietly wreak havoc on your health in many ways, influencing everything-from your energy to the health of your skin. Recurring fatigue, mood swings or skin issues are related to poor gut health in ways that many people might not realize. The good news? There are natural ways to heal your gut with consistent, conscientious efforts towards a healthy lifestyle.

Recognizing early warning signs and addressing them is the first step in becoming healthier, more energized, and in better balance.

Dr Rashmi Khanna, Delhi based Gastroenterologist told Moneycontrol, "Our gut is an ecosystem that thrives on balance. Simple alterations to diet, lifestyle and distraction techniques can provide a resolution to tummy troubles and markedly improve quality of life. Getting to know early indicators for when our balance starts to deteriorate, is how we can make corrections before it becomes a chronic issue.”

8 Signs of an Unhealthy Gut

Frequent Bloating or Gas

Continuous or excessive bloating and gas may show that your digestive system is finding it difficult to properly break down food, possibly as the result of a balance issue with gut bacteria.

Irregular Bowel Movements

Constipation, as well as diarrhoea can both be a sign of poor function within the gut. A good gut will promote easy regular bowel movements.

Unexplained Fatigue

Poor digestion can hinder nutrient absorption, resulting in low energy levels and tiredness.

Skin Problems

Gut inflammation and poor detoxification can be fuelling acne, eczema, or dull skin.

Frequent Sugar Cravings

The overgrowth of unhealthy bacteria that feeds on sugar, inducing strong cravings, which only further throw the balance in your stomach off.

Mood Swings and Anxiety

The gut makes a large portion of the body’s serotonin, the “feel-good” hormone. A disrupted microbiome can influence mood regulation and mental health.

Food Intolerances

If you suddenly become intolerant of certain foods, you could have inflammation or damage to your gut lining.

Weakened Immunity

The immune system - More than 70 percent of your body's immune system is located in the digestive tract. If you get a lot of colds or other infections while your gut defenses are low, your gut may be defenseless.

Restoring Gut Health Naturally

Eat a diet that is rich in fibre and well-balanced, full of fruits, vegetables and whole grains.

Include fermented foods such as yogurt, kefir, kimchi and sauerkraut for natural probiotics.

Cut out sugar and processed food, which bacteria feed on.

Hydrate to assist with digestion and detoxing.

– Practice stress reduction by doing meditation, yoga or deep breathing.

Sleep 7–8 hours per night.

Exercise on a regular basis for good digestion.

Always ask your doctor before consuming probiotic supplements for personalized recommendations.
