The microbial population of the gut, or gut microbiota is extremely dense, predominantly comprising bacteria. Whilst a core community of gut microbes—approximately one third—is common to most healthy adults, the composition of each gut microbiota varies according to factors including genetics, diet, age, state of health and geographical location. Microbes are considered important—but probably not essential—to digestion. This is primarily because the gut microbiota breaks down substances that the gut alone is unable to digest and is also involved in synthesis of vitamins.

The liver plays an important role in the digestion and processing of proteins, fat and sugar. The liver helps create some of the building blocks of proteins needed for the body known as amino acids. The liver plays an important role in fat digestion as well as the production of fats needed for the function of different organs of the body. Simple sugars are created in the liver by breaking down both proteins as well as more complex sugars known as glycogen. The liver can also convert simple sugar into glycogen which is better for storage. In this way the liver acts as an energy center for the body. It controls the balance of simple and complex sugar storage and releases sugar stores when needed for energy.

Recovery after bariatric surgery takes time and patience. The diet is strict. You may experience discomfort and pain as your body heals. The length of time to return to normal activities can vary from patient to patient. Some patients are able to return to work within a few weeks and see weight loss soon after surgery. For others, a couple of months go by before they experience noticeable weight loss. From lifestyle changes to health transformations that change lives, life after surgery is full of both successes and challenges.
