The Kidney Dam

When blood glucose rises above a certain level, it is removed from the body in urine. Picture the kidney as a dam: when there is too much glucose in the blood, the excess "spills" out. The maximum blood glucose level reached before sugar spills out is called the kidney threshold (usually about 180 mg/ml).

Some people with long-term diabetes or kidney disease can have a very high kidney threshold. Sugar will not " spill" into the urine until the blood sugar is very high.

Glucose cannot be passed out of the body alone. Sugar sucks up water so that it can "flow" from the body. The result is polyuria or excessive urination. People with excess glucose in their blood, as in uncontrolled diabetes, make frequent trips to the bathroom. These people also have sugar in their urine; the medical term for sugar in the urine is glycosuria.

Loss of water through urination triggers the brain to send a message of thirst. This results in a condition called polydipsia, or excessive thirst. This symptom is not always pronounced, however; you may notice nothing more than a dry mouth.

Excessive urination can result in dehydration, leading to dry skin.

Blurred vision can be caused by fluctuations in the amount of glucose and water in the lenses in your eyes during periods of dehydration.

When there is no insulin to funnel glucose into the body's cells, or when the insulin funnel is not working to pass glucose through the receptors, the cells get no fuel and they starve.

When there is no insulin to funnel glucose into the body's cells, or when the insulin funnel is not working to pass glucose through the receptors, the cells get no fuel and they starve.

This triggers the brain to send a message of hunger, resulting in polyphagia or excessive hunger. Because the glucose that should be fueling your cells is flowing out in urine, the cells cannot produce energy, and without energy, you may feel weak or tired. Weight loss may occur in people whose bodies produce no insulin because without insulin, no fuel enters their cells.

Insulin also works to keep fuels inside the cells. When insulin is low, the body breaks down the fuels, and rapid weight loss results. The breakdown of fat cells forms fatty acids which pass through the liver to form ketones. Ketones are excreted in the urine. The medical term for ketones in the urine is ketonuria.

Skin infections sometimes occur because excess sugar in the blood suppresses the natural defense mechanism like the action of white blood cells. And sugar is an excellent food for bacteria to grow in.

Numbness and tingling in feet and night leg cramps may result from nerve damage due to prolonged high glucose levels that cause changes in the nerves.
