Diabetes mellitus refers to metabolic disorders that are characterized by the presence of high blood sugar for a long period. This condition is due to either insulin insufficiency or insensitivity of body cells to insulin. The condition has three main symptoms which include; increased thirst, excessive hunger and increased frequency in passing urine (Katsarou et al., 2017). Several complications are associated with diabetic ketoacidosis, diabetic foot, hyperosmolar hyperglycemic state, retinopathy, and damage to the nerves. Therefore, although there is no definitive cure for diabetes, there is a need to investigate the various medications that can be used to alleviate the symptoms of the condition such as insulin.

To get a clear understanding as to why insulin is very essential in diabetes, it is important to understand clearly how our body uses food for the generation of energy. The human body is made up of millions of cells. To make the needed energy, these human body cells need food in the simplest form. When we eat or even drink, food is broken down into glucose which is a very simple sugar that can be utilized by the body cells. Thereafter, glucose is then transported via the bloodstream to the cells of the human body where it can be used to give energy that the body needs for the execution of all the daily activities.

The amount of glucose found in the bloodstream is closely controlled by the hormone known as insulin. Insulin is usually released in little amounts by the human pancreas (Paari & Pari, 2019). When the amount of glucose in the blood increases to a certain level, the pancreas then releases more insulin to enable more glucose to get into the cells. This process causes the levels of glucose in the blood to decrease. People with diabetes have either reduced insulin levels (type I diabetes mellitus) or insulin resistance (type II diabetes mellitus) (Ali, Ayaz, Dar, Singh, Bhat & Razak, 2017). Therefore, insulin is a suitable medication for type I diabetes mellitus whereby individuals have a low insulin level.
