Excessive consumption of sugar can never cause diabetes. If you know the pathogenesis of diabetes, you will understand the disease has nothing to do with sugar. There is a cascade of medical conditions that brings about diabetes mellitus or diabetes insipidus.
(1) Failure of the islet of Langer hans in pancreas to produce and secrete a polypeptide hormone called insulin brings about Diabetes mellitus. The insulin is responsible for the movement of sugar (glucose) from the blood stream to the tissues, where they are utilized in energy production by the mitochondria of cells. If the blood has high concentration of glucos, due to pancreatic failure, secondary to some diseases such as pancreatitis, pancreatic tumour etc, large amount of glucose will be excreted through the kidneys in the urine. A condition called glucosuria. The patient will be weak, the urine will be sugary and as a result, the body will be looking for an alternative source of energy, hence fat will be utilized, leading to a condition called Ketoacidosis. In a nutshell, Diabetes mellitus of this type is caused by pancreatic failure to produce insulin. Type 2 diabetes mellitus is a condition in which there is availability of insulin but the body fails to utilize it. Hyperglycemia means high blood sugar level. Like i explained before, it occurs in diabetes bcos of either absence of insulin secretion by the pancrease (Type 1 diabetes mellitus) or inability of the body to utilize the available insulin (Type 2).
Glucose is needed in the tissues not to be present in the large quantity in the blood. The glucose storage form in the tissues is called glycogen. When it is present in the blood in large quantity, it is an abnormality the patient starts excreting large amount in the urine through the kidney. Such a diabetic patient is advised to desist from sugar consumption, starchy food and any form of high carbohydrate food. With that, the blood sugar level can be controlled and monitored. Next is to place the patient in insulin injection. Head aches, blurred vission, weakness, lack of concentration, joint pains among many other symptoms have been associated with hyperglyceamia.
On the other hand, hypoglycemia too affect human health negatively. My concern is the way sugar has been so criminalised, just like cholesterol. Cholesterol will be a topic for another day. An individual with a functional pancreas has no reason to be afraid of sugar.
