During digestion the human body breaks down carbohydrates (bread, milk, pasta, vegetables) into sugar molecules. One of these sugar molecules is glucose, the main sugar. Glucose needs to leave the bloodstream where it first inside the body enters and needs to enter cells where it will be used as energy for the body. For this to occur the beta cells in the pancreas must secrete insulin. Insulin is a natural body hormone, and it is needed in our bodies to let glucose enter cells and muscles. Any excess glucose that enters the body will be stored in the liver and muscles in the form of glycogen.

Symptoms of developing type 2 diabetes are tiredness, often more thirsty than usual, deterioration in eyesight and often craving more food than usual. People are more likely to develop type 2 diabetes if they have a family relative that also has this type of diabetes, but anyone can develop this.
The reason type 2 diabetes occurs is
Type 1 diabetes can occur at any age more is more commonly diagnosed in children or young adults. The exact reason why type 1 diabetes occurs is unknown. In diabetes type 1 the body mistakenly attacks the cells in the pancreas that make insulin. So for type 1 diabetics to get glucose into their cells they must inject themselves with insulin regularly.
Symptoms for type 1 diabetes includes thirst, urge to urinate more often, weight loss, constant mood changes and fatigue. Some more serious symptoms include abdominal pain and skin infections.
Diabetes is not necessarily hereditary but a person is more likely to develop diabetes if they have relatives who also have this auto-immune disease. There is no cure for type 1 diabetes at this point in time but it really important to make sure diabetics keep track of their blood glucose levels, blood pressure and blood fats as it will help reduce their risk of developing kidney …show more content…
Environmental fluctuations would be a rise and decrease in blood glucose levels.
If someone who is not diabetic consumes too much sugar, the beta cells will detect this increase in glucose entering the body and then send a signal to the islets inside the pancreas which secrete and make insulin to do so. This needs to happen as cells use glucose as energy which is needed for aerobic respiration to occur.
Insulin has to be made so the glucose can enter the cells, insulin signals cells to absorb the glucose from the bloodstream. The glucose is then used as energy, any excess glucose that is consumed but not needed is then stored
If someone’s blood glucose levels drop and they are not diabetic, their internal homeostatic system instantly responds to make up for this loss. The alpha cells are alerted by this drop in glucose levels, they signal the islets to release stored glucose (glycogen) in the liver as glucose into the bloodstream.
