What are the roles of probiotics? How about daily oral probiotic supplements?

In the United States, most food stores and pharmacies have probiotic products on their shelves or aisles.
pill, which contains billions of bacteria, needs to be taken daily, claiming to relieve digestive problems, among other benefits.
daily oral probiotics are very popular as health products, with sales reaching $36.6 billion in 2015.
many people suffer from a variety of chronic gastrointestinal diseases, leading to long-term discomfort or worse.
but according to gastroenterologists and other scientists, these probiotic supplements don't seem to be as useful as they claim to be.
Fact, there is not enough research to prove that these probiotic products can help people treat specific diseases," said Matthew Ciorba, a gastroenterologist and director of the Inflammatory Intestinal Disease Program at the University of Washington.
"Although various probiotic products on supermarket shelves claim to be good for the gut, most of the products on the market do not undergo any kind of clinical trial to prove their efficacy."
and get FDA approval before going on the market, almost no.
generally, all drugs, whether prescription or over-the-counter, need to be tested by the FDA to determine safety and effectiveness before they can be marketed, meaning that these drugs have been shown to actually do what they claim to do.
but do not treat any disease do not need to be subject to a rigorous vetting process, and probiotics take advantage of this hazy state to market.
probiotics are actually strains that are thought to be beneficial to the gastrointestinal tract.
there are many bacteria in our bodies that help us digest food, prevent us from being intruded by toxins, and keep our guts healthy.
the past 20 years, scientists have recognized the importance of these microbes to our health and survival.
these findings, probiotic supplements are beginning to appear in stores, claiming to relieve indigestion.
most of the early probiotics were Lactobacillus and B ambiobacteria, which are used in food fermentation and are also found in yogurt and kimchi.
they have not under rigorous clinical trials, have not been licensed by the FDA, and the bacterial composition of these supplements has not changed for many years.
that while some tout these probiotic supplements as a cure for all digestive problems, no one knows for sure whether they can treat the disease, " he said.
the probiotics were just beginning to become endemic, the FDA wasn't sure what to do with them, " said Ciorba, a health care expert.
is not only a natural product, but also a living product, " he said.
they may be used by different populations to treat diseases.
the FDA has become more active, someone is starting to study these amazing microbes, " he said.
just as antibiotics can treat all bacterial infections, there are no probiotics that can treat all intestinal diseases.
to figure out which probiotics treat which disease, it will take a lot of time and effort to study.
we may one day be able to design and sell probiotics for specific diseases, but not yet."
market and media misdirection has led us to the use of ineffective probiotics.
Cciorba said: "For Crohn's disease and ulcerative colitis, we have well-used drugs, and we know how they work and how they work.
but patients say they don't want to take these drugs, just probiotics.
we tell patients that probiotics don't help in clinical trials, they say, "I'd like to give it a try," " he said.
", there is another benefit to buying probiotics.
buying a bottle of probiotics online is much easier than telling a doctor that he has a problem with intestinal peristalsis.
but Ciorba admits that patients should not be blamed instead.
past, doctors have not been able to explain well what gastrointestinal symptoms are associated with.
, for example, doctors are still unable to say exactly what causes irritatative bowel syndrome, which affects 11 percent of the world's population.
, it's no wonder patients are looking for this "natural" treatment.
exactly what is the role of probiotics? Ciorba says probiotics are still on the market, but it's important for consumers to know exactly what causes their gastrointestinal illness.
many gastroenterologists do not recommend probiotics, but this also depends on the patient's condition.
and the probiotics recommended by doctors are products that have been proven effective in clinical trials.
, for example, Align probiotic capsules contain Bipolibial strains that have been tested and proven to be helpful for a particular condition: women with irritabillive bowel syndrome.
Ciorba said that in his experience, he did find Align helpful to some patients.
some lactic acid bacteria and Bacch yeast can reduce the time and severity of symptoms in patients with diarrhea due to antibiotic use.
Ciorba often recommends a brand of probiotics that contain lactic acid bacteria, which can help with gastrointestinal diseases caused by bacterial or viral infections and reduce the duration of symptoms.
but for other gastrointestinal diseases, such as crohn's disease and inflammatory bowel disease such as ulcerative colitis, the situation is more complex.
study did not find probiotics to be effective for Crohn's disease, and they appear to be only useful in patients with mild colonitis.
use microbes to improve health is always exciting, but the process can take a long time, says Ciorba, a professor at the U.S. Institute of Health.
, Ciorba does not recommend buying and using probiotics simply because it "feels good for the gut."
that while they are generally safe for most people, there is always a risk of getting sick, which is one of the main reasons why the FDA is so strict in its management.
future, all probiotics that claim to be able to treat specific diseases will need FDA approval.
are the probiotics of the future? Ciorba says researchers are trying to figure out how the bacteria are beneficial to humans.
all bacteria, including probiotics, produce metabolites that are small molecules that play a specific role in the gut.
some metabolites to help break down food and keep the intestines healthy.
if researchers were able to isolate these metabolites, they could make drugs that contain only molecules of useful metabolites, " he said.
but the study is just beginning, Ciorba suspects it is likely that scientists will eventually discover that bacteria themselves are needed.
these bacteria are a good way to give medicine, " he said.
they can do the work of metabolites in the right place, either on the colon wall or in mucus, whereas metabolites don't necessarily work in some places.
"Now, if the digestive system is good, there is no need to take probiotics.
but if you're very keen to try it, try it rationally.
if taking probiotic supplements once a day for a month doesn't make you feel better, don't waste your money on it.
