For all patients, the atrategies of MNT include avoidance of weight gain, consistency in day-to-day carbohydrate intake at meals Hyperglycemia prevention strategies snacks, and balanced nutritional content.
MNT may be customized to achieve body weight reduction and is reviewed in detail elsewhere. See 'Diet' below and "Medical nutrition therapy Apple cider vinegar for immunity type preventino diabetes mellitus".
Weight management Efficient body recomposition techniques For patients with type 2 diabetes, body weight management should be considered as a therapeutic target in addition to glycemia.
Patients should receive counseling regarding changes in diet and physical activity to achieve weight loss or to prevent weight gain.
Weight loss improves glycemia through mitigation of insulin resistance and impaired beta cell function, two major metabolic perturbations evident in type 2 diabetes [ 12,13 ]. For patients who have difficulty achieving weight loss, weight maintenance Hyperglycemiw than gain is an alternative goal.
Strategies for weight management include lifestyle change, pharmacologic therapy, and metabolic surgery. Lifestyle change includes diet and physical activity, as well as behaviors that facilitate these changes, and is an essential component of any weight management plan.
We emphasize lifestyle change as our initial approach to body weight reduction and reserve pharmacotherapy and metabolic surgery for patients who do not achieve targeted weight loss with lifestyle change alone. We tailor our specific recommendations to patients' goals and preferences and encourage "intensive" lifestyle modification, where available, for highly motivated patients.
Diet — Diagnosis of type 2 diabetes is often a powerful motivator for lifestyle change. Dietary modification is a highly effective strategy for weight loss and for management of glycemia and hypertension in patients who are willing to commit to it, with metabolic benefit likely outlasting the effect of weight loss per se.
The improvement in glycemia is related both to Hyperglyceia degree of caloric restriction and weight reduction [ 12,14,15 ]. Body weight loss of 5 to 10 percent may also improve nonalcoholic steatohepatitis, sleep apnea, and other comorbidities of type 2 diabetes [ 16 ]. Consumption of sugar-sweetened beverages, including natural fruit juice, should be specifically queried and strongly discouraged in order to manage glycemia, weight, and reduce risk for CVD and fatty liver [ 17 ].
See "Medical nutrition therapy for type 2 diabetes mellitus", section on 'Designing a nutrition care plan' and "Management of nonalcoholic fatty liver disease in adults", section on 'Initial lifestyle interventions'. In a two-year analysis of the DiRECT trial, only 11 percent of intervention participants had weight loss of 15 kg or more compared with 24 percent in the one-year analysis [ 18 ].
However, 36 percent of participants maintained diabetes remission, compared with 3 percent of control patients. Several studies have evaluated the long-term efficacy of diet alone or with exercise in patients with newly diagnosed type 2 diabetes see "Medical nutrition therapy for type 2 diabetes mellitus".
In the United Kingdom Prospective Diabetes Study UKPDSfor example, all patients were given a low-calorie, low-fat, high complex carbohydrate diet [ 21 ]. Furthermore, the mean glucose value was substantially higher with diet alone than with diet plus an oral hypoglycemic drug or insulin.
The likelihood of a successful glycemic response to diet is determined in large part by the initial fasting blood glucose. Pharmacologic therapy — Pharmacotherapy targeted solely for weight management is effective in patients with type 2 diabetes.
Although metformin is usually started for the management of hyperglycemia, it is also frequently an effective medication Hyperglgcemia promote modest weight loss.
When additional body weight reduction is a primary goal of therapy, we choose medications that shrategies weight loss and lower glucose. Glucagon-like peptide 1 GLP-1 receptor and dual GLP-1 and glucose-dependent insulinotropic polypeptide GIP agonist therapies promote weight loss and help prevent weight gain due to other glucose-lowering pharmacotherapies.
We add these medications sequentially to metformin if additional glucose lowering or weight loss is a treatment goal. See "Glucagon-like peptide 1-based therapies for the treatment of type 2 diabetes mellitus" and "Obesity in adults: Drug therapy".
Surgical therapy — Weight loss surgery in patients with obesity and type 2 diabetes results in the largest degree of sustained weight loss and, in parallel, improvements in blood glucose management and the most frequent sustained remissions of diabetes.
Weight loss surgery is an option to treat poorly managed type 2 diabetes when other modalities have failed. This topic is reviewed in detail separately. See "Management of persistent hyperglycemia preventiln type 2 diabetes mellitus", section on 'Bariatric metabolic surgery'.
Exercise — Regular exercise is beneficial in type 2 diabetes, independent of weight loss. It leads to improved glycemic management due to increased responsiveness to insulin; it can also delay the progression of impaired glucose tolerance to overt diabetes [ 22,23 ].
These beneficial effects are directly due to exercise, but concurrent weight reduction plays a contributory role. In one study, however, only 50 percent of patients with type 2 diabetes were able to maintain a regular exercise regimen [ 24 ].
See "Exercise guidance in adults with diabetes mellitus". Shorter-duration, intensive exercise may be appropriate for physically fit individuals [ 25 ]. Resistance training may be particularly important for individuals with type 2 diabetes who do not have overweight or obesity, in whom relative sarcopenia may contribute to diabetes pathophysiology [ 26 ].
Intensive lifestyle modification — In patients with established type 2 diabetes, intensive behavioral modification interventions focusing on weight reduction and increasing activity levels are successful in reducing weight and improving glycemic management while, at the same time, reducing the need for glucose-lowering and other medications [ 15,18, ].
The intensive intervention included caloric restriction maximum 30 percent calories from fat, minimum 15 percent protein, and the remainder from carbohydrates, in the form of liquid meal replacements, frozen food entrees, or structured meal plansmoderate-intensity physical activity goal minutes weeklyand weekly group or individual sessions with registered dietitians, behavioral psychologists, and exercise specialists.
The primary outcome was a composite of death from cardiovascular causes, preventtion myocardial infarction, nonfatal stroke, and hospitalization for angina. Although the anticipated follow-up period was After a median follow-up of 9.
The improvement in weight and glycemia did not reduce the occurrence of cardiovascular events. Possible reasons for this finding include the lower-than-expected rates of cardiovascular events in both groups, improved overall cardiovascular risk factor treatment with medical therapy antihypertensives, statins in the standard diabetes education arm, enrollment of a relatively healthy patient population, gradual weight loss in the control group such that the differential weight loss between the two groups was only 2.
A sustained weight loss of greater than that achieved in the trial may be required to reduce the risk of CVD. In an observational post hoc analysis of the Look AHEAD trial, weight loss of 10 percent or greater in the first year was associated with a reduction in the primary outcome 1.
However, this post hoc analysis is problematic. Moreover, the degree of weight loss is difficult to achieve and maintain through lifestyle intervention alone.
Weight loss, weight loss maintenance, and exercise remain important components of diabetes management due to overall health benefits. The following summarizes several other major observations from the Look AHEAD trial [ 27,31, ]:.
The difference was attenuated but remained significant throughout the trial 6 versus 3. Changes in waist circumference and physical fitness were also significantly better in the intervention group throughout the study.
By study end, mean A1C was significantly lower in the intervention group 7. Psychological interventions — Patients with type 2 diabetes often experience significant stress, a condition often called diabetes distress, related to the many self-care Hyperglyvemia required for glycemic management lifestyle modifications, medication, and blood glucose monitoring [BGM] [ 42 ].
Concurrent depression similarly may interfere with self-care. See "Overview of general medical care in nonpregnant adults with diabetes mellitus", section on 'Comorbid conditions'. Psychotherapy reduces psychological distress and improves glycemic management in some [ 43,44 ], but not all [ 45 ], studies.
In a meta-analysis of 12 trials of prdvention with type 2 diabetes randomly assigned to psychological intervention or usual care, mean A1C was lower in the intervention group pooled mean difference Measures of psychological distress were also significantly lower in the intervention group, but there were no differences in weight management.
Pregnancy planning — All women of childbearing age with diabetes should be counseled about the potential effects of diabetes and commonly used straetgies on maternal and fetal outcomes and the potential impact of pregnancy on their diabetes management and any existing complications.
See "Pregestational preexisting diabetes: Preconception counseling, evaluation, and management". When to start — Early institution of treatment for diabetes, at a time when the A1C is not substantially elevated, is associated preventioon improved glycemic management over time and decreased long-term complications [ 46 ].
Pharmacologic therapy should be initiated along with consultation for lifestyle modification focusing on dietary and other lifestyle contributors to hyperglycemia. Weight loss and weight loss maintenance underpins all effective type 2 diabetes therapy, and lifestyle change reduces the risk of weight gain associated with sulfonylureas and insulin.
However, for those patients who have clear and modifiable contributors to hyperglycemia and who are motivated to change them eg, commitment to reduce consumption of sugar-sweetened beveragesa three-month trial of lifestyle modification prior to initiation of pharmacologic strategkes is warranted.
Choice of initial therapy — Our suggestions are based upon clinical trial evidence and clinical experience in achieving glycemic targets and minimizing adverse effects table 1 prrvention, with the recognition that there is a paucity of high-quality, head-to-head drug comparison trials and long-duration trials or ones with important clinical endpoints, such as effects on complications.
The long-term benefits and risks of using one approach over another are unknown. In selecting initial therapy, we consider patient presentation eg, presence or absence of prevetion of hyperglycemia, comorbidities, baseline A1C levelindividualized treatment goals and preferences, the glucose-lowering efficacy of individual drugs, and their adverse effect profile, tolerability, and cost [ 47 ].
We prefer initiating a single agent typically metformin and then sequentially adding additional glucose-lowering agents as needed, rather than starting with combination therapy [ 48 ]. Related Pathway s : Diabetes: Initial therapy for non-pregnant adults with type 2 DM.

| What causes hyperglycemia? | You may not be able to eat or drink as much as usual, which can affect blood sugar levels. This is especially important for people with type 1 diabetes since they depend on insulin to live. When too many ketones are produced too fast, they can cause diabetic ketoacidosis , or DKA. DKA is very serious and can cause a coma or even death. If you think you may have DKA, use an over-the-counter kit to test your urine for ketones. If ketones are present, call your doctor right away. You may also need to drink beverages with sugar if you cannot get 50 grams of carbohydrates every 4 hours from other food choices. Drink small portions of these sweet beverages to keep your blood sugar from getting too high. Skip directly to site content Skip directly to page options Skip directly to A-Z link.

Everything You Ever Wanted to Know About Head Lice. This facilitates a consequent decline in high insulin and high blood glucose levels, with no effect on insulin secretion.
The primary mechanism involved in lowering blood glucose levels is through improving hepatic and peripheral tissue sensitivity to insulin [ 40 ]. It inhibits the production of glucose by the liver whilst enhancing uptake of circulating glucose and its utilization in peripheral tissues such as muscle and adipose tissue.
Hepatic gluconeogenesis is an energy-demanding process in which synthesis of one molecule of glucose from lactate or pyruvate requires four molecules of ATP and two molecules of GTP. Metformin suppresses hepatic gluconeogenesis by causing a reduction of cellular ATP levels [ 41 ]. Molecularly, metformin appears to inhibit mitochondrial respiration.
The resulting shift in cellular energy balance increases the activity of AMP-activated protein kinase AMPK , which promotes the action of insulin and reduces hepatic gluconeogenesis [ 42 ].
Upon activation by a decrease in cellular energy levels, AMPK initiates a change from anabolic to catabolic pathways that consume ATP. This stimulates the uptake and use of glucose and oxidation of fatty acids, in addition to the suppression of hepatic glucose production.
Multiple studies have demostrated that one of the mechanisms of action of metformin is the disruption of mitochondrial complex I [ 45 , 46 ].
Metformin may also modulate the gut-brain-liver axis through the activation of a duodenal AMPK-dependent pathway, as has been demonstrated in rats. This effect involves activation of protein kinase A Pka by GLP-1 in duodenal enterocytes, and results in suppression of hepatic glucose production [ 47 ].
These indicate the likelihood of converse effects of steroids and metformin in the AMPK signaling pathway, as well as the overriding of steroid effects by metformin [ 44 , 48 ]. Supporting studies demonstrate that steroid-related increase in glucose levels can be prevented with an AMPK activator [ 49 ].
Another postulated mechanism of action for metformin is by causing an increase in circulating cyclic adenosine monophosphate cAMP which in turn opposes the hyperglycemic action of glucagon [ 42 , 50 ]. Metformin has also been postulated to increase the concentration of Glucagon-like peptide-1 GLP-1 by enhancing site production as well as subsequently decreasing its degradation in circulation and specific tissues via inactivation of the enzyme dipeptide peptidase-4 DPP Additionally, metformin may induce up regulation of GLP-1receptors on beta cell surfaces of the pancreas.
This can aid in ameliorating the beta cell dysfunction associated with hyperglycemia via the enhancement of the role of GLP-1 on glucose dependent release of insulin [ 11 ]. Metformin has been identified as a first line agent in treatment of type 2 diabetes mellitus. Recent studies have shown that it confers a greater benefit to patients than the other oral diabetic agents, which has led to its recommendation for use in the prevention of prediabetes in at risk patients [ 34 , 35 , 51 ].
Presently though, only a few nations have formally adopted this proposal such as Poland, Philippines and Turkey but many may adopt it in the near future based on the emerging evidence [ 11 ].
Metformin overrides most of the factors that contribute to poor glycemic management like inaccessibility to medicine and fear of developing hypoglycemia.
This improves patient perception on its use regardless of the minimal side effects. In addition, it has been demonstrated to confer long term benefit to those who use it prophylactically. In a prospective observational study in persons with normal glucose tolerance and hyperinsulinemia, a dose of 2.
Over the observation period, the effect of metformin on the reduction of hyperinsulinemia increased over time, peaking after 1 year of treatment. The ability to lower fasting blood glucose levels also improved with time. Fasting blood glucose levels reached normoglycemic range at 3 months and remained so until the end of the 1 year observation period, with no development of hypoglycemia [ 39 ].
A substantial decrease in hyperinsulinemia from high blood glucose levels has also been reported in metformin-treated patients based on an increase in the uptake of glucose [ 52 ].
The enhancement of insulin action reduces the load on the beta cells in insulin secretion thus can aid in ameliorating the beta cell dysfunction to an extent; this confers an advantage to patients predisposed to developing hyperglycemia.
In addition, a randomized controlled study showed that there was no significant difference in blood glucose levels between critically ill patients receiving mg of metformin daily versus a similar spectrum of patients receiving 50 International Units IU of regular insulin.
Furthermore, metformin-treated patients had blood glucose levels subside to near-normal range [ 40 ]. The targeted desired blood glucose levels were achieved with metformin after three days while insulin failed to do the same.
Blood glucose levels never exceeded The one patient who developed hyperglycemia during relapse re-induction for leukemia treatment was effectively controlled using metformin alone [ 53 ]. Three of the patients given insulin therapy due to high blood glucose levels were eventually weaned off insulin to metformin alone.
Additionally, in a controlled trial consisting of non-diabetic patients on glucocorticoids, metformin prevented an increase of 2-hour glucose AUC with, signifying glucose tolerance preservation. No changes in baseline and after 4 weeks metformin treatment was seen with the 2-hour glucose AUC whereas this parameter increased in the placebo group [ 54 ].
Similarly, the effect of metformin on prednisone-induced hyperglycemia PIH was observed on fasting and 2-hour post prandial glucose levels in hematological cancer patients.
The fasting blood glucose readings indicated a proportion of prednisone-induced hyperglycemia of The proportion was slightly lower while using the 2-hour post prandial glucose, in which Double daily dosing mg twice daily was more effective in preventing prednisone-induced hyperglycemia [ 21 ].
The limitations attached to the full exploitation of metformin use include its relative contraindications in many hospitalized patients who present with comorbidities like renal insufficiency or unstable hemodynamic status.
Emerging evidence shows that the established cut-off points for renal safety may be overly restrictive [ 56 ]. It has been argued that there is a need to relax these cut-offs and policies to allow use of this drug to patients with stable chronic kidney disease characterized by mild—moderate renal insufficiency [ 57 , 58 , 59 ].
The associated risk of lactic acidosis tends to deter the use of metformin in majority of the comorbid patients on drugs that predispose to the development of hyperglycemia.
However, the studies that made such recommendations used a small percentage of the patient population, thus limiting the extrapolation of these recommendations to the greater public [ 60 ].
Fortunately, the incidence of metformin-induced lactic acidosis is rare and can be significantly reduced in at-risk patients by observing the necessary precautions [ 27 , 56 ]. Other factors may also play a greater role in in being predictors of acidosis, such as dehydration, severe heart and renal failure.
Thus, its benefits for use outweigh the potential risk of lactic acidosis. Supporting evidence on avoidance of metformin use in certain cases is poor and inconsistent such as in patients undergoing radio-contrast imaging which theoretically predisposes patients to media-induced nephropathy, increasing the risk of lactic acidosis [ 56 ].
The benefits of metformin in the prevention of hyperglycemia are unmatched despite its list of contraindications. This has facilitated its expanded use based on its well-founded glycemic effects as well as numerous benefits conferred such as the beneficial effect on reduction of development of cardiovascular risk factors [ 61 ].
It confers good glycemic management that yields a substantial and enduring decrease in the onset and progression of micro vascular complications [ 60 ]. Moreover, large based clinical trials and systematic reviews have shown its beneficial effect of enhancing weight loss, even the weight loss associated with medicaments like antipsychotic agents [ 62 , 63 ].
Metformin has been shown to reduce the incidence of hyperglycemia-related complications such as diabetes and risk factors for cardiovascular disease in patients with impaired glucose tolerance and fasting blood sugar [ 11 , 64 , 65 ]. This has led to its endorsement of use in patients with high risk of developing the aforementioned conditions [ 36 ].
