Hi everyone, I am a gastroenterologist with ten years of experience. Over the course of my career, I have witnessed countless examples of how gut health can profoundly impact our overall health. What many people may not know is that our gut is known as the "second brain", and this is not for nothing. In fact, the billions of bacteria in our gut not only affect our digestion, but may also affect our mood, immune system, and even our ability to fight cancer.
Let me share a case that I will never forget, which gave me a deep understanding of the importance of the gut microbiota. A few years ago, I met a middle-aged woman who came to me with persistent stomach pain and indigestion. She has tried multiple medications, but her condition has not improved significantly. Through in-depth conversations, I learned that she has an extremely irregular diet and has been dependent on antibiotics for a long time. This caught my attention, as such a lifestyle is most likely disrupting the balance of her gut flora.
At my suggestion, she began a series of changes, including adjusting her diet and gradually reducing unnecessary drug use. After a few months, not only did her stomach pain lessen, but she also felt a noticeable improvement in her overall health. This case once again confirmed the importance of gut health and inspired me to continue to promote the correct gut maintenance knowledge to my patients.
Gut microbiota and cancer
Overview of scientific research
In recent years, scientific research has begun to reveal how the gut microbiota influences the development and efficacy of cancer treatments. Studies have shown that a healthy gut microbiota may inhibit the growth of cancer cells through a variety of mechanisms. For example, certain gut bacteria produce short-chain fatty acids, such as butyric acid, which have been shown to inhibit the growth of colon cancer and other types of cancer cells.
In addition, gut microbes can also influence the immune system's response, enhancing the body's immune surveillance of cancer cells. Studies have shown that cancer patients with higher gut microbiome diversity respond more positively to certain immunotherapies and show better treatment outcomes.
Practical case sharing
Let's go through a few real-world examples to learn more about the relationship between gut microbiota and cancer. In one case study, a colon cancer patient who not only improved their gut health by changing their diet and increasing their intake of probiotic supplements, but also showed better chemotherapy outcomes in subsequent treatments. Doctors observed that with the improvement of intestinal flora, the patient's level of inflammation was significantly reduced, and the anti-cancer immune response in the body was also enhanced.
These cases highlight the potential of optimizing gut health as part of a comprehensive cancer treatment regimen, suggesting a deeper understanding and respect for the impact of gut microbes.
In the journey of discovering how to harness the gut microbiota to fight cancer, each individual's experience is unique. While these findings offer hope, they also remind us that we must be cautious when applying this knowledge to ensure that all treatments are administered under the guidance of medical professionals.
In this way, the gut microbiota's relationship with cancer not only advances our understanding of the nature of disease, but also opens up new therapeutic avenues and gives us the opportunity to combat this global health challenge with a fresh perspective.
Ways to self-diagnose gut health
Observe the color of the stool (see one)
First of all, the color of the stool can tell us a lot about the health of the body. Normal stools are usually of various shades of brown, thanks to the role of bile in the digestive process. If you notice a very dark black stool, it may be a sign of gastrointestinal bleeding, and if the stool is grayish-white, it may indicate impaired liver or gallbladder function. If these abnormal colors persist, you should consider consulting a doctor.
Observe the morphology of the stool (see 2)
Morphology is just as important. We usually refer to the Bristol Poo Morphology Chart, which is a standard used by the medical community to assess the type of stool. The ideal stool should be type 3 or 4, shaped like a banana, with a soft and continuous texture. If the stool is small, hard balls, this can be a sign of dehydration or insufficient fiber intake, and if it is watery or very loose, it may be a sign of indigestion or infection.
Smell the smell of poop (smell)
Finally, I have to mention the smell. While the smell of poop is usually unpleasant, an unusually bad smell — especially a very pungent odor — may indicate indigestion or an intestinal infection. For example, a type called C. Difficile infections can cause a very distinctive and strong odor.
When to seek help from a doctor
Although "look and smell" is a useful self-diagnostic tool, it is not a substitute for professional medical advice. Contact your doctor if you notice any of the following symptoms:
A sudden change in the color of the stool, especially persistent black or white stools.
Sudden changes in stool morphology, such as persistent diarrhea or constipation.
Unusual stool odor, especially if accompanied by other symptoms such as abdominal pain or sudden weight loss.
With these basic observation techniques, you can better understand your gut health. Remember, identifying problems early and seeking treatment is key to maintaining your health.
Practical strategies to enhance the intestinal microbiota
Dietary advice
Increase fiber intake: Fiber is a prebiotic that promotes the growth of a healthy flora. Foods including legumes, whole grains, nuts, seeds, and plenty of fruits and vegetables are excellent sources of fiber.
Eat more fermented foods: Fermented foods such as yogurt, kimchi, capers, and miso contain probiotics, which directly replenish your gut flora.
Limit processed foods and sugar intake: Too much processed foods and sugar can promote the growth of harmful microflora, which can disrupt the balance of the gut flora.
Lifestyle modifications
Exercise regularly: Moderate exercise can not only improve your mental health, but also promote gut health. Exercise helps to increase the diversity of your gut microbiota, which is extremely important for overall health.
Avoid unnecessary antibiotics: Antibiotics can kill pathogenic bacteria, but they can also destroy healthy gut flora. Try to avoid antibiotics unless your doctor thinks it's necessary.
Manage stress: Long-term stress can have a negative impact on the gut flora. Try to manage daily stress through meditation, yoga, or other relaxation techniques.
Additional Recommendations:
Consider probiotic supplements: If dietary changes are not enough to improve gut conditions, consider using probiotic supplements. It's best to consult with a health professional before choosing the best product for you.
With these simple yet effective strategies, you'll not only boost your gut flora, but also your overall health. Remember, small changes can make a big difference! Don't forget, the gut is our second brain, and we should give it the love and support it deserves.
