Don't Ignore These Signs Of An Unhealthy Gut

An unhealthy gut refers to an imbalance in the composition and function of the gut microbiome—trillions of bacteria, viruses, and fungi that live in the digestive tract. When harmful microbes outnumber the beneficial ones, or when the gut lining is damaged, it can lead to a wide range of digestive and systemic issues. Since the gut plays a central role in digestion, immune regulation, mental health, and nutrient absorption, even slight disruptions can have a ripple effect throughout the body. An unhealthy gut often goes unnoticed until symptoms become persistent or affect daily life. Read on as we share signs of an unhealthy gut.
Signs of an unhealthy gut you shouldn't ignore
1. Persistent bloating and gas
Frequent bloating and excessive gas, especially after eating, may indicate imbalanced gut bacteria or difficulty digesting certain foods. It can be a sign of small intestinal bacterial overgrowth (SIBO) or a lack of digestive enzymes, both of which hinder proper digestion and cause discomfort.
2. Constipation or diarrhoea
Chronic constipation or diarrhoea can signal an unhealthy gut. When the gut microbiome is imbalanced, it affects how efficiently waste moves through the colon. Too few good bacteria can lead to sluggish digestion (constipation), while inflammation or infection can result in frequent loose stools (diarrhoea).
3. Frequent heartburn or acid reflux
Acid reflux or persistent heartburn may result from an imbalance in stomach acid or the growth of harmful bacteria like H. pylori. An unhealthy gut can also weaken the lower oesophageal sphincter, allowing stomach contents to back flow and cause burning sensations.
4. Food intolerances or sensitivities
If you suddenly find yourself reacting poorly to foods you once tolerated well like dairy, gluten, or certain vegetables, it could indicate gut inflammation or damaged intestinal lining. This can cause your immune system to overreact to certain food proteins.
5. Unexplained fatigue or low energy
When your gut is unhealthy, nutrient absorption is often compromised. Deficiencies in iron, vitamin B12, and magnesium can lead to fatigue. Additionally, chronic inflammation in the gut can trigger fatigue as the body diverts energy to immune responses.
6. Skin problems
The gut-skin connection is powerful. Toxins from a leaky or imbalanced gut may enter the bloodstream and trigger inflammation, leading to flare-ups of acne, eczema, or rosacea. Many chronic skin issues are now linked to gut health disturbances.
7. Mood swings, anxiety, or depression
The gut produces about 90% of the body's serotonin, the feel-good hormone. An unhealthy gut can interfere with this production, contributing to mood disorders. Also, gut inflammation may trigger the release of cytokines that affect brain function and mood.
8. Frequent infections or low immunity
Over 70% of the immune system is located in the gut. If you're constantly getting sick, catching colds easily, or recovering slowly, your gut may not be supporting your immune defence effectively. Poor gut health weakens the barrier against harmful pathogens.
9. Bad breath
Persistent bad breath, especially when not related to oral hygiene, can point to digestive issues. Imbalanced gut bacteria can create foul-smelling gases and toxins that rise up from the digestive tract into the mouth.
Recognising the signs early can help prevent chronic conditions and improve overall health.

'Doctors said my weight loss was anxiety, then I was diagnosed with cancer'

Bruna Gettert's symptoms had been dismissed by doctors A student has shared her experience of being repeatedly dismissed by doctors, despite losing 10 kilos in just two months and suffering from severe abdominal pain. Bruna Gettert began to question herself, but eventually, a diagnosis confirmed what she had long suspected - she had cancer. Although her condition continued to deteriorate, Bruna was prescribed antidepressants, and her symptoms were consistently overlooked. It took a whopping two years and two months for her to receive a proper diagnosis in 2023, but by then, the cancer had already spread. ‌ Bruna was informed that she had a 10-centimetre mass in her abdomen and metastases in her liver—findings that finally explained her persistent stomach pain. ‌ The business administration student from Caxias do Sul, Brazil, had first started experiencing symptoms at age 20, in late 2020. Alongside heartburn, nausea, indigestion, diarrhea and intense abdominal pain, she lost 10 kilograms in just two months - dropping from 45 to 35 kilos, explains Although she underwent imaging and blood tests, no major abnormalities were found. Doctors suggested her symptoms could be related to anxiety, potentially brought on by her young age and the pressures of living through a pandemic. Before receiving her diagnosis, the student consulted at least six healthcare professionals, including GPs and gastroenterologists. She was treated for H. pylori, prescribed gastric protectors, underwent two endoscopies, had abdominal ultrasounds, and even had her gallbladder removed. Despite all these measures, her symptoms persisted and not even the surgeon who performed the gallbladder surgery detected anything unusual. ‌ She recalls: 'The doctors said no findings justified such intense symptoms. They said I was too young and must be anxious because of the pandemic. "I started to believe it was all in my head. I was very debilitated but began to think I was making it up.' She was referred to a psychiatrist and prescribed antidepressants, which provided slight relief from her lack of appetite. However, her condition deteriorated in early 2023, and she began struggling to swallow both solids and liquids. ‌ After collapsing, she was taken to the hospital, where she was finally diagnosed with cancer. During the emergency consultation, the student recalled feeling truly validated for the first time. Doctors ordered a blood test which revealed severe anemia and she admitted quickly. Another endoscopy uncovered a small nodule in the cardia - the area between the stomach and esophagu - which explained her difficulty swallowing. Later that same day, a CT scan uncovered a 10-centimeter mass situated between the pancreas, retroperitoneum, and the curvature of the stomach, along with metastases in the liver. ‌ Following a series of biopsies, the initial diagnosis was gastrointestinal stromal tumour (GIST). Bruna began treatment with imatinib, but it had no effect and caused severe side effects, including bleeding and vomiting blood. A second treatment attempt with sunitinib led to a reduction in the abdominal mass, shrinking it to approximately 6 centimetres. However she recalled: "I had drug-induced hepatitis; my face swelled up; I bled from my mouth and nose; I lived in the hospital." ‌ It was only then in March 2024, after consulting a specialist in Porto Alegre and re-analysing last year's biopsy, she discovered that the first diagnosis was wrong. The student did not have a gastrointestinal stromal tumour, but rather a well-differentiated grade 2 neuroendocrine tumour. According to the student, the correct diagnosis had already been identified in one of the previous biopsies but was ignored by doctors for reasons she has not been made aware of. The new diagnosis changed the therapeutic strategy. The student is on her third medication, which has stabilised her condition and alleviated symptoms, but has not cured the disease. "I am considered a palliative patient," she states. ‌ "People say I handle everything lightly, but I just allow myself to feel. What hurts is that my complaints were invalidated because I was too young," Bruna adds. The student took to TikTok to tell people about her experience. Speaking on the video sharing platform, @eibrunagettert shared: "I have a well-differentiated grade 2 neuroendocrine tumour, and this main tumour is located in the region of the pancreas, retroperitoneum and gastric curvature. "It's about 7 centimetres at the moment. I discovered it when it was 10 centimetres, and managed to partially reduce it, but I also have metastases in my liver, so yes, it's in the digestive system in a way." ‌ What is a neuroendocrine tumour? According to Cancer Research UK: "Neuroendocrine cancers are a group of cancers that develop in cells of the neuroendocrine system. They can develop in different parts of the body, such as the stomach, bowel, pancreas or lungs." They explain that this system is made up of nerve pathways and neuroendocrine cells. "You have neuroendocrine cells throughout your body. ‌ "Your brain sends these nerve signals. In response they make and release hormones and similar substances. These keep our bodies working properly," they write. There are neuroendocrine cells throughout the body. They are in almost all organs and endocrine glands, including your: food pipe (oesophagus) stomach lungs small and large bowel pancreas appendix You can read more about the different type of cancer as well as its staging via the Cancer Research UK website here.

Gastroenterologist shares why so many Indians use antacids, reveals 5 big risks

If having antacid has become a post-meal norm for you, then it's time to rethink your choices. Acidity is an uncomfortable situation to be in, making the med feel like a saviour, and before you know, it has become a habit. It's easy to dismiss poor dietary choices when you think an antacid has your back (or at least that's what you thought). While antacids may be a quick fix but in the long run, it's not a solution. Your trust fall on antacid may eventually turn disastrous, it's only a matter of time. Act before antacids backfire, and choose safer alternatives to address gas problems. In an interview with HT Lifestyle, Dr Anukalp Prakash, Director of Gastroenterology at CK Birla, Gurugram, warned against the casual use of antacids. Addressing the dangerous trend of casually consuming antacids, Dr Prakash said, 'India's drugstores are filled with antacids, those fizzy tablets, chewables, or syrups that we usually reach for after a spicy dinner or a gassy day. But as a gastroenterologist, I've witnessed the flip side of this dependency. The increasing trend of self-medication with antacids is not just a cultural practice, it is a manifestation of underlying lifestyle and medical problems that require better treatment.' Dr Anukalp Prakash shared a detailed guide with us, highlighting why Indians use antacids, the big risks of overusage, safer alternatives and when to go see a doctor: Occasional usage is okay, regular antacid consumption, particularly without medical guidance, can cause: They both relax the lower esophageal sphincter and inflame the gut lining, enhancing acid reflux. Allow digestion time for your stomach first. Raise the head of your bed if nocturnal reflux is an issue. If symptoms persist, your doctor may recommend endoscopy or tests for H. pylori, a common bacterial infection that causes acidity, ulcers, and even long-term stomach issues. Seek help if: 'Acidity is normal, but only so long as it's rare or occasional. Antacids give fast relief, but they don't fix the issue. A whole approach, lifestyle, diet, and medical advice, gives longer and safer relief. Don't self-treat endlessly; your gut wants better attention,' Dr Anukalp Prakash concluded.

Acid Reflux and Burping Too Often? When It's Time to See a Houston GI Doctor

REPORT Listly by Ahmed Ahmed It's normal to burp occasionally after a big meal or a fizzy drink.

Ignoring them may allow your condition to worsen, making treatment more complicated. Could It Be Gastritis? Yes. Stomach inflammation gastritis can mimic symptoms of acid reflux but is often caused by damage to the stomach lining. This can result from bacterial infections, long-term NSAID use, or lifestyle factors. Chronic gastritis can lead to ulcers, bleeding, or even an increased risk of stomach cancer. A Houston GI doctor can diagnose gastritis using tools like: Upper endoscopy Blood tests Stool tests Urea breath test for H. pylori Once diagnosed, treatment often includes acid-suppressing medications, antibiotics (if H. pylori is present), and diet modifications. Why Choose a Digestive Disease Center Near You in Houston? When symptoms persist, early intervention at a digestive disease center near me can prevent complications. The benefit of seeing a Houston GI specialist includes: Personalized diagnosis and care State-of-the-art diagnostic tools Proven treatments for acid reflux burping, gastritis, and more Ongoing management and lifestyle guidance Take Control of Your Digestive Health Don't brush off frequent acid reflux burping or ignore stomach discomfort.
