Another study published in the same journal, however, examined the effect of chromium on glycemic control in insulin-dependent people with type 2 diabetes. People were given either 500 or 1,000 mcg a day of chromium or a placebo for six months. There was no significant difference in glycosylated hemoglobin, body mass index, blood pressure, or insulin requirements across the three groups.
Schedule a yearly physical exam and regular eye exams. Your regular diabetes checkups aren't meant to replace regular physicals or routine eye exams. During the physical, your doctor will look for any diabetes-related complications, as well as screen for other medical problems. Your eye care specialist will check for signs of retinal damage, cataracts and glaucoma.
If you have gestational diabetes, you should first try to control your blood glucose level by making healthy food choices and getting regular physical activity. If you can’t reach your blood glucose target, your health care team will talk with you about diabetes medicines, such as insulin or the diabetes pill metformin, that may be safe for you to take during pregnancy. Your health care team may start you on diabetes medicines right away if your blood glucose is very high.
Dr. Sivitz emphasizes the importance of being active, eating a healthy diet, and having a good understanding of the role that carbohydrates play. He recommends eating healthy carbs, such as nonstarchy vegetables, fruits, legumes, whole grains, and nonfat dairy products. A certified diabetes educator or a registered dietitian can help personalize your diet and teach you strategies to control your blood sugar. Depending on your desired blood sugar range and weight loss goals, recommendations for foods, carbohydrate intake, and portion sizes may vary. Regardless, if you have diabetes, it will be important to count carbs in your diet because, while not off limits, they can lead to blood sugar spikes when overeaten.
Type 2 diabetes develops when the body cannot use insulin properly or make enough insulin, so the body cannot properly use or store glucose (a form of sugar) and sugar backs up into the bloodstream, raising blood sugar levels. In the United States, some 8.9 percent of adults 20 and older have been found to have diabetes, and health officials estimate that another 3.5 percent have undiagnosed diabetes.
Within the hepatocyte, fatty acids can only be derived from de novo lipogenesis, uptake of nonesterified fatty acid and LDL, or lipolysis of intracellular triacylglycerol. The fatty acid pool may be oxidized for energy or may be combined with glycerol to form mono-, di-, and then triacylglycerols. It is possible that a lower ability to oxidize fat within the hepatocyte could be one of several susceptibility factors for the accumulation of liver fat (45). Excess diacylglycerol has a profound effect on activating protein kinase C epsilon type (PKCε), which inhibits the signaling pathway from the insulin receptor to insulin receptor substrate 1 (IRS-1), the first postreceptor step in intracellular insulin action (46). Thus, under circumstances of chronic energy excess, a raised level of intracellular diacylglycerol specifically prevents normal insulin action, and hepatic glucose production fails to be controlled (Fig. 4). High-fat feeding of rodents brings about raised levels of diacylglycerol, PKCε activation, and insulin resistance. However, if fatty acids are preferentially oxidized rather than esterified to diacylglycerol, then PKCε activation is prevented, and hepatic insulin sensitivity is maintained. The molecular specificity of this mechanism has been confirmed by use of antisense oligonucleotide to PKCε, which prevents hepatic insulin resistance despite raised diacylglycerol levels during high-fat feeding (47). In obese humans, intrahepatic diacylglycerol concentration has been shown to correlate with hepatic insulin sensitivity (48,49). Additionally, the presence of excess fatty acids promotes ceramide synthesis by esterification with sphingosine. Ceramides cause sequestration of Akt2 and activation of gluconeogenic enzymes (Fig. 4), although no relationship with in vivo insulin resistance could be demonstrated in humans (49). However, the described intracellular regulatory roles of diacylglycerol and ceramide are consistent with the in vivo observations of hepatic steatosis and control of hepatic glucose production (20,21).
He emphasizes lifestyle changes and weight loss as a first step. "We give them a 3-month trial of diet and lifestyle [modification] before starting medications," he says. "A lot of times, for many patients newly diagnosed, we will see the sugars melt back into the normal range" after the weight loss and other changes. He has seen it happen after a weight loss of 7% to 10% of their starting weight.
Drugs of this class decrease the absorption of carbohydrates from the intestine. Before being absorbed into the bloodstream, enzymes in the small intestine must break down carbohydrates into smaller sugar particles, such as glucose. One of the enzymes involved in breaking down carbohydrates is called alpha-glucosidase. By inhibiting this enzyme, carbohydrates are not broken down as efficiently, and glucose absorption is delayed.
