10 Signs of an Unhealthy Gut You Should Never Ignore

Time to read 6 min

Gut health refers to a balanced gut microbiome consisting of healthy bacteria and bad bacteria in the digestive system. Unbalanced gut bacteria can disturb the digestive processes, causing an unhealthy gut. The good and bad bacteria, or intestinal flora, play a significant role in gut health. Intestinal flora imbalance makes your digestive system unable to digest food well, reduces nutrient absorption, and affects the immune system as well.

What is an Unhealthy Gut?

An unhealthy gut means that it can negatively impact your overall health:

  • Decreased good bacteria

  • Increased bad bacteria

  • Slower digestion

  • Gut inflammation

  • Weak gut lining


Common gut imbalance symptoms include frequent digestive problems, persistent fatigue, food intolerances, skin concerns, mood swings, and brain fog. Intestinal flora imbalance symptoms are not just associated with your gut, but also impact your overall digestive health. It affects digestion, skin, the body's immune system, hormones, and mental well-being.

Common Symptoms of Poor Gut Health

Poor gut health is caused due to an imbalance of harmful bacteria and good bacteria in the gut, referred to as dysbiosis. Bad gut symptoms include digestive problems as well as systemic issues ranging from mild gastrointestinal discomfort to severe symptoms.


Here are the common symptoms of bad gut health and other gut problems :

  • Digestive issues such as gas, bloating, constipation, diarrhea, acidity, indigestion, and feeling full quickly.

  • Food intolerances such as difficulty digesting certain foods and sensitivity to dairy products, spicy foods, or gluten.

  • Lethargy, weakness, low energy, and persistently feeling tired even after taking adequate rest.

  • Skin problems such as dry and itchy skin, rashes, acne, and eczema.  

  • Recurrent illness, signs of weak immunity, and easily catching common colds and viral infections.

  • Mental health issues such as mood swings, anxiety, brain fog, and concentration problems.

  • Unexpected weight fluctuations, such as sudden weight loss or gain, and trouble losing weight.


The 10 Warning Signs of an Unhealthy Gut

Here are the gut health warning signs related to eliminating waste that you should never ignore:

10 signs of an unhealthy gut

Persistent Bloating & Excessive Gas

Often feeling gassy after meals is the topmost warning sign of an unhealthy gut.

Constipation, Diarrhea, or Irregular Bowel Movements

Irregular bowel movements are common indicators of unhealthy digestion.

Ongoing Heartburn, Acidity, or Indigestion

Feeling discomfort, a heavy and burning sensation after meals, shows that your digestive system is not working well.

Unexplained Fatigue or Low Energy Levels

Feeling tired, weak, and having low energy levels after taking proper rest and sleep indicates a problematic gut.

Skin Problems (Acne, Eczema, Dryness, Rashes)

Skin problems such as persistent dryness and acne are usually associated with gut inflammation, which can be alleviated by incorporating fermented foods into your diet.

Frequent Food Intolerances & Sensitivities

Food sensitivities and difficulty digesting certain foods, such as gluten and dairy products, may indicate gut health problems.

Excess Sugar Cravings or Poor Appetite Control

Excessive craving for refined sugars and poor appetite control may be a warning sign of an imbalanced gut affecting blood sugar levels.

Anxiety, Irritability, or Mood Swings

Mood swings, brain fog, and anxiety are usually associated with an unhealthy gut, as it influences brain function.

Low Immunity & Repeated Infections

Easily getting sick and catching common infections indicates weak immunity that is linked to improper digestion.

Unexplained Weight Gain or Weight Loss

Sudden weight fluctuations without any significant lifestyle or diet changes can be a sign of an unhealthy gut.

Signs of Bad Gut Health in Women

When it comes to unhealthy gut-related problems in women, they may experience some additional symptoms other than digestion-related issues. Here are the common signs of bad gut health in women that you should not ignore:

  • Hormonal acne

  • PCOS-related bloating

  • Menstrual fluctuations

  • Recurrent vaginal infections

  • Water retention around the cycle


Gut Imbalance & Intestinal Flora Disruption

Gut flora is responsible for gut health, and gut flora imbalance is called gut dysbiosis. Intestinal flora disruption is typically caused by dietary, lifestyle, and medical factors.

Common causes of gut and intestinal flora imbalance:

  • Poor diet (too much sugar and processed foods)

  • Too much intake of antibiotics

  • Chronic stress

  • Low fiber diet

  • Excessive alcohol consumption

  • Irregular sleep

  • Gastrointestinal infections

  • Hormonal fluctuations in women

  • Chronic conditions


Symptoms directly linked to the dysbiosis may include chronic fatigue :

  • Digestive disturbances (bloating, gas, constipation, acidity, abdominal cramping)

  • Food intolerances (dairy, gluten, fermented, and high-fibre foods)

  • Persistent fatigue and low energy levels

  • Skin concerns (acne, rashes, eczema, psoriasis)

  • Difficulty concentrating

  • Mood swings (anxiety, low mood, irritability)

  • Persistent bad breath

  • Frequent illnesses

  • Foul-smelling stools

  • Unexpected weight fluctuations


How Microbiome Imbalance Affects Digestion, Mood & Immunity

Microbiome imbalance increases bad bacteria and reduces the healthy microbiome, which leads to improper digestion. It causes poor nutrient absorption and digestive discomfort.


A healthy microbiome releases major neurotransmitters (serotonin), and gut flora imbalance disrupts the production of these chemicals. As a result of the gut-brain connection involving the central nervous system, it leads to mood swings, brain fog, and irritability.


Around 70% of your immune function is associated with gut health. To combat this and promote a healthy body, taking probiotic supplements may help restore gut flora. Gut flora disruption weakens immune cells and increases inflammation, making your body vulnerable to allergies, infections, and diminishing recovery.

When Should You Consult a Doctor?

If you have persistent digestive discomfort that affects your daily activities, it's time to seek professional advice.

  • Severe abdominal pain
