Type 2 diabetes is a severe body impairment and a chronic medical condition resulting from the high sugar or glucose level in the body circulating in the bloodstream. Type 2 diabetes can also be explained as a condition in the body when the cells cannot produce energy using blood sugar effectively. This medical ailment happens when there is a high blood sugar level, making the cells insensitive to insulin and could then make the body not produce enough insulin. 
Type 2 diabetes is also usually known as adult-onset diabetes. This is because it is more common in adults. However, there has been some increase in children suffering from this ailment, especially children with obesity.  When type 2 diabetes is not controlled at an early stage, it could lead to severe complications.
In type 2 diabetes, since the body fails to use insulin effectively, the body then depends on either the muscles, organs, and tissues as a source of energy. This ailment does not just happen suddenly. Instead, it develops slowly.
Symptoms of Type 2 Diabetes
The medical term for constant or extreme hunger is polyphagia  or hyperphagia.  Polyphagia is a severe case of one continuously getting hungry even after one must have eaten. This symptom of type 2 diabetes occurs at the early stage of the disease and could be easily overlooked, blood level of glucose is high, so blood do not enter cells where they are needed, leading to the body being unable to change the food you eat into energy. The absence of energy is responsible for the constant feeling of hunger.
