Without insulin, that extra sugar starts to hang out in your blood with nowhere to go. Just like with honey or sweet syrup, high concentrations of sugar causes the blood to thicken. Physiologically, this pulls fluids and water from other parts of the body into the bloodstream, causing swelling and dryness. Early symptoms of diabetes are relatively mild, including excessive peeing, dry mouth, itchy skin, hunger, fatigue, and blurred vision.
She says that the problem with diabetes is that it’s a silent disease. “Apart from needing to go to the loo a few times in the middle of the night, I experienced zero symptoms. Diabetes had no impact on my life – 99% of the time I forgot I even had it. Perhaps if it had been a disease with more symptoms, I would have been more motivated to do something about it.”
Recent global increase in diabetes, especially type II diabetes, is a product of the global obesity epidemic and attendant increase in Metabolic syndrome. In turn this has fueled an increase in surgical intervention in the form of Bariatric surgery. Diabetes reversal often follows sustained weight loss and indeed a 2014 Cochrane review of such surgeries found diabetes improvement in 5 randomized clinical trials (4). However, depending on the country and insurance plans, such weight loss surgery can be costly. They're also not risk-free with risks varying greatly depending on the person's overall health profile and age as well as skill and experience of the surgeon.
Many usage guides have disparaged preventative as improper, because it doesn't accord with classical roots: the Latin past participle stem praevent- adds -ion to form prevention and -ive to form preventive. Words ending in -ative ought to have the -at- in the root already: demonstrat- begets demonstration and demonstrative, narrat- begets narration and narrative, and so forth. Since we don't have preventation, then preventative is equally misbegotten, by this way of thinking.
When the glucose concentration in the blood remains high over time, the kidneys will reach a threshold of reabsorption, and glucose will be excreted in the urine (glycosuria). This increases the osmotic pressure of the urine and inhibits reabsorption of water by the kidney, resulting in increased urine production (polyuria) and increased fluid loss. Lost blood volume will be replaced osmotically from water held in body cells and other body compartments, causing dehydration and increased thirst (polydipsia).
To explain what hemoglobin A1c is, think in simple terms. Sugar sticks, and when it's around for a long time, it's harder to get it off. In the body, sugar sticks too, particularly to proteins. The red blood cells that circulate in the body live for about three months before they die off. When sugar sticks to these hemoglobin proteins in these cells, it is known as glycosylated hemoglobin or hemoglobin A1c (HBA1c). Measurement of HBA1c gives us an idea of how much sugar is present in the bloodstream for the preceding three months. In most labs, the normal range is 4%-5.9 %. In poorly controlled diabetes, its 8.0% or above, and in well controlled patients it's less than 7.0% (optimal is <6.5%). The benefits of measuring A1c is that is gives a more reasonable and stable view of what's happening over the course of time (three months), and the value does not vary as much as finger stick blood sugar measurements. There is a direct correlation between A1c levels and average blood sugar levels as follows.
Diabetes is a number of diseases that involve problems with the hormone insulin. Normally, the pancreas (an organ behind the stomach) releases insulin to help your body store and use the sugar and fat from the food you eat. Diabetes can occur when the pancreas produces very little or no insulin, or when the body does not respond appropriately to insulin. As yet, there is no cure. People with diabetes need to manage their disease to stay healthy.
