Bacteria are a part of normal flor of human body. They are present inside the body naturally and play an important role. Most importantly they are present in the gastrointestinal tract. They play both intestinal and extraintestinal roles. Due to their large effects on human health, they can also be injected artificially. There are also bacteriophages, fungi, and protozoa. They all are residents of the human body. Altogether their collective genome is called as the microbiome. In the human body, there are 10 times more microbial cells as compared to human cells. This shows their intervention in maintaining the homeostasis.
Role in health
As they are part of the human body they have vast effects on human health. They provide immunity and protect against pathogens. They help our immune system to grow. The memory cells of immune system learn a lot from them. They become better at detecting foreign agents. In this way, they also prevent auto-immune diseases. This altogether has healthy physiological effects on the body. They help in digestion and absorption of certain vitamins. Some of them work as transporters and carriers. All this makes them an integral part of human body.
Role in improving insulin
The human microbiome is diverse. It has a number of organisms, each one of them with their respective genome. This makes a whole world of their own. As far as insulin is concerned they play the significant role directly or indirectly. If you maintain a handsome level of the microbiome in your body, you will have better options to improve your insulin level. Disturbed and poorly regulated insulin levels can lead to hypo or hyperglycemia, shock, stroke and even death. Therefore, it is very important to regulate insulin in the human body. If you improve your microbiome they will regulate the insulin in following ways:
By affecting insulin resistance
These organisms play an important role in decreasing insulin resistance. Insulin resistance develops when there is decreased sensitization of body cells towards insulin. Lactobacillus species reduces this effect.
By affecting digestion
They help in digestion which regulates the amount of glucose in the blood. Insulin is the hormone that acts on glucose. By regulating the amount of glucose they control the amount of insulin.
By decreasing obesity
They have extraintestinal effects that include regulation of cholesterol synthesis. They control the distribution of fats in adipose tissue. this in turns decreases the insulin resistance.
By regulating bile acids and short chain fatty acids
These microorganisms regulate the secretion and formation of bile acids and SCFA. They help in gluconeogenesis in liver. As the amount of glucose is being regulated, the secretion of insulin is automatically affected.
By directly acting on the pancreas
The pancreas is the main source of insulin in the human body. They approach pancreas by regulating the amount of bile. Due to their profound effects on the pancreas, they directly improve the insulin levels. So, if the human body is in a hyperglycemic state, this eventually tackles the emergency.
In order to summarize, the microbiome is very essential for human body. they are present in diversity and large amounts. As insulin is a very important hormone, directly or indirectly they regulate and improve its level. There are five ways mentioned how insulin can be improved by improving the variety of microbiome. These are the ways how these microorganisms improve your insulin level. If you want a good insulin balance, improve your percentage of the microbiome.
