The growth of the market can be attributed to the growing focus on the human immunity system post-COVID-19 as people with low immunity were most affected by the pandemic. According to the World Health Organization as of 23rd March 2023, there have been 761,071,826 confirmed cases of COVID-19 worldwide, which includes 6,879,677 deaths to date. Moreover, the increasing role of gut microbiota in immunity besides the rising research on how to improve gut flora is further expected to boost the market growth.
In addition to these, factors that are believed to fuel the market growth of gut microbiota include soaring investments, and collaboration between major key players to study & develop the human microbiome therapy to the next level. For instance, as per a new Bar-Ilan University study, gut microbes are anticipated to diagnose gestational diabetes as early as the first trimester of pregnancy which is months earlier than typically detected. The rising concern about gestational diabetes mellitus (GDM) worldwide which plagues around 10% of pregnant women across the globe is predicted to present the potential for market expansion over the projected period.
Gut Microbiota Market Growth Drivers and Challenges:
Growth Drivers
-
Growing Prevalence of Gastrointestinal (GI) Tract Diseases – gut microbiota being a vast and complex collection of microorganisms affects human health in many ways. They are essential in helping humans to absorb nutrients. Therefore, the rising prevalence of the GI tract amongst the global population owing to an increase in the consumption of unhealthy foods, and surging stress levels among middle age people worldwide are anticipated to propel the market growth. It is observed that in the United States, the estimated prevalence of irritable bowel syndrome is between 11% and 14% and this share is predicted to increase further in the upcoming years.
-
Increasing Ubiquity of Type 1 & Type 2 Diabetes - the alterations in the intestinal bacterial composition are known to be associated with the presence of chronic low-grade inflammation. This is a characteristic of insulin resistance and type 2 diabetes mellitus. The rising ubiquity of type 2 diabetes worldwide is anticipated to boost the market growth in the forecast period. As per research, over 37 million Americans are suffering from diabetes (nearly 1 in 10), and around 90-95% of them have type 2 diabetes.
-
Rising Health Spending – Recent expenditure data states that health spending worldwide has increased over the past 20 years, doubling in real terms to reach USD 8.5 trillion in 2019 and 9.8% of GDP, up from 8.5 percent in 2000. With the rising concern of low microbial diversity in the gut among children and middle age populations, the market is estimated to flourish over the forecast period.
-
Surging Prevalence of Diarrhea in Children – According to the World Health Organization report, diarrhea is listed as the second general cause of death in children under the age of 5, killing nearly 500 000 children under the age of 5 every year. Moreover, about 2 billion children worldwide suffer from diarrheal sickness every year.
As there are both, good and bad bacteria present in the gut, the entrance of harmful bacteria in the GI tract causes infection. Hence, the market is expected to grow at a substantial rate with the increasing research & spending to curb such infections that cause food poisoning and other GI diseases that result in diarrhea and vomiting among the populaces.
Challenges
- High Cost Associated with the Development of Microbiome Diagnostics Platform - the research and development proficiencies in the field of microbiome diagnosis drastically depend upon the employed platform, technologies, and infrastructural facilities. These facilities are limited and inadequate for research on the human microbiome and gut microbiota. This, as a result, is anticipated to hamper the market growth in the upcoming years. Moreover, the lack of suitable infrastructure in low- and middle-income countries as well as slow technology penetration in these countries is further restricting market growth.
- Lack of Favorable Reimbursement Scenario
- Lack of Qualified Professionals & Supporting Staff
