By checking your own blood sugar levels, you can track your body's changing needs for insulin and work with your doctor to figure out the best insulin dosage. People with diabetes check their blood sugar up to several times a day with an instrument called a glucometer. The glucometer measures glucose levels in a sample of your blood dabbed on a strip of treated paper. Also, there are now devices, called continuous glucose monitoring systems (CGMS), that can be attached to your body to measure your blood sugars every few minutes for up to a week at a time. But these machines check glucose levels from skin rather than blood, and they are less accurate than a traditional glucometer.
“The degree of carbohydrate restriction that we recommend to establish and then maintain nutritional ketosis depends upon individual factors such degree of insulin resistance (metabolic syndrome or type 2 diabetes?) and physical activity. These starting levels of carb restriction typically vary between 30 and 60 grams per day of total carbs. The best way to determine one’s carbohydrate tolerance is to directly measure blood ketones with a finger-stick glucometer that also accommodates ketone testing.
These are a relatively new class of drugs used to treat type 2 diabetes. They are oral medications that work by blocking the kidneys' reabsorption of glucose, leading to increased glucose excretion and reduction of blood sugar levels. The US FDA approved the SGLT2 inhibitors canagliflozin (Invokana) in March 2013 and dapagliflozin (Farxiga) in January 2014.
The problem is, glucose is actually toxic if it is just floating around in your bloodstream, so that body has a defense mechanism. Any glucose that is not immediately used is stored as glycogen in the liver and the muscles. This would be all well and good except that your body has a limited number of glycogen receptors. When these are full, as they almost always are in inactive people, the body only has one option left: to store all the excess glucose as saturated fat within the body.
Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas. This release of insulin promotes the uptake of glucose into body cells. In patients with diabetes, the absence of insufficient production of or lack of response to insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
