The latest medical information on gastroenterology that was right then but wrong now!
If you have recurring intestinal problems, such as diarrhea or constipation, that even doctors don't recognize...
Pay attention to small intestinal bacterial overgrowth (SIBO).

Supervised by Professor Na-young Kim of Bundang Seoul National University Hospital, the first Korean recipient of the Marshall & Warren Research Award
“I applaud the author’s flexibility in demonstrating that the distinction between beneficial and harmful bacteria in the digestive tract is not particularly important, but rather the microenvironment in which intestinal bacteria live is more important.”
Professor Na-Young Kim, Department of Gastroenterology, Seoul National University College of Medicine and Seoul National University Bundang Hospital

What is small intestinal bacterial overgrowth (SIBO)?

Author Akashi Eda boldly states that the advice to eat a lot of dietary fiber and probiotics is wrong, and emphasizes that to properly understand the gastrointestinal tract, you need to know intestinal bacteria.
This is because it is difficult to apply to everyone the medical information that is floating around, such as reducing harmful bacteria and increasing beneficial bacteria to cure intestinal problems, or having more slimming bacteria rather than fat-promoting bacteria to prevent obesity.
In reality, the types of gut bacteria that people have are as diverse and unique as fingerprints, and show significant differences depending on gender, age, and eating habits.


Small intestinal bacterial overgrowth (SIBO) occurs when gut bacteria grow abnormally in the wrong habitat.
Unlike the large intestine, the small intestine is narrow in diameter, so if gas is produced by bacterial fermentation, it can become excessively distended, which can be problematic.
If the intestinal bacterial environment in the small intestine deteriorates and is not corrected, reflux esophagitis, peptic ulcers, and irritable bowel syndrome can occur.
This book focuses on the relationship between the digestive tract and intestinal bacteria, providing an easy-to-understand explanation of the mechanisms by which common intestinal problems occur in our bodies.


Drugs, treatments, and diets that can help prevent gut bacteria from overrunning.

Intestinal problems such as diarrhea, constipation, abdominal bloating, and indigestion are often diagnosed as stress because the cause cannot be clearly identified.
However, the author focuses on the problem of dysbiosis, or unbalanced gut bacteria, and identifies the abnormal symptoms of the body one by one.
Additionally, based on papers and comparative studies published in renowned international journals such as [Nature] and [American Journal of Gastroenterology], and sometimes based on my experience as a clinical specialist, I approach appropriate prevention and treatment methods.


The medical information the author has acquired through his interest in domestic and international treatment methods is expected to be useful knowledge for the public as well.
It not only corrects misconceptions about gut health by providing information such as common misconceptions about probiotics and the 17 types of bacteria found in the intestines of people who have lived long and healthy lives, but also serves as a guide in choosing the most ideal medicine, treatment, and diet.
As regulations regarding treatment and medicine vary from country to country, a gastroenterologist familiar with the current situation in our country was in charge of reviewing the book.
For reference, Professor Na-Young Kim, who conducted the review, is the first Korean to receive the Marshall & Warren Research Award and is a renowned gastroenterologist who has been researching Helicobacter pylori and digestive system diseases for over 30 years.


Optimal gut environment managed with a low FODMAP diet

This book suggests a variety of strategies for gut health, including the use of low-tolerance medications, improving the gut environment through fecal transplants, intermittent fasting, and a gluten-free diet. It particularly recommends a low-FODMAP diet.
Unlike medication or hospital treatment, it is a method that anyone can easily access at home and has a 75% improvement effect in intestinal problems.
This diet, which limits carbohydrate intake, which causes rapid bacterial fermentation in the small intestine and leads to abdominal bloating, abdominal pain, constipation, and diarrhea, is ideal for maintaining a stable intestinal environment.


The low FODMAP diet, developed at Monash University in Australia for patients with irritable bowel syndrome, is known to significantly alleviate symptoms in patients with ulcerative colitis and Crohn's disease.
Recently, it has reached the stage of being applied to SIBO patients, and its biggest advantage is that it can directly find the intestinal bacteria and excessively fermented carbohydrates (high FODMAPs) that each individual has.
For example, some people can eat fructan (bread), but eating galactooligosaccharides (beans) can cause particularly severe intestinal problems, while the opposite is true for some.
Professor Kim Na-young, the reviewer, said that the high-FODMAP/low-FODMAP food list included in this book is very useful because Japanese and Koreans have similar eating habits, mainly consuming fermented foods, rice, and steamed dishes.
