Metformin and insulin resistance -

Total and free testosterone levels decreased significantly, and six patients reported improvement in menstrual cyclicity. Hormone response to ACTH stimulation was significantly reduced after treatment. The authors conclude that in obese adolescents with PCOS and impaired glucose tolerance, metformin can improve glucose tolerance and insulin sensitivity, reduce insulinemia, and lower elevated androgen levels.

The drop in the exaggerated adrenal response to ACTH stimulation with treatment may correct FAH. The side effects of three months of metformin treatment are minimal and easily tolerated.

Further blinded, placebo-controlled studies are needed to confirm these effects of metformin. editor's note: The hyperandrogenism and chronic anovulation of PCOS make this condition a common cause of infertility that affects up to 6 percent of women of reproductive age.

Because regular menses and ovulation resume with metformin therapy, Heard and associates studied pregnancy outcomes in anovulatory infertile women with PCOS who were treated with metformin.

This study included some women who reported previous treatment with clomiphene citrate and some who did not. Forty-eight patients began taking metformin at a dosage of mg twice daily for six weeks, and the dosage was increased to mg three times daily if there was no ovulatory response.

After six weeks on the highest dosage of metformin with no response, 50 mg per day of clomiphene citrate was added to the metformin regimen for a maximum of six cycles.

An ovulatory response based on midcycle monitoring of luteinizing hormone occurred in 40 percent of patients with metformin alone, and 60 percent responded after the addition of low-dose clomiphene.

After three months of treatment, 20 women conceived. Side effects of metformin were self-limiting, but 10 percent of patients had to reduce the dosage. Further studies are needed to evaluate the role of metformin as a fertility drug.

People with insulin resistance, also known as impaired insulin sensitivity, have built up a tolerance to insulin, making the hormone less effective.

As a result, more insulin is needed to persuade fat and muscle cells to take up glucose and the liver to continue to store it. Just why a person fails to respond properly to insulin is still a mystery. But there are ways to make the body more receptive to insulin, which can help prevent or delay type 2 diabetes—or help someone with type 1 diabetes manage their blood glucose blood sugar.

In response to the body's insulin resistance, the pancreas deploys more of the hormone to keep cells energized and manage blood glucose levels in a healthy range. This is why people with type 2 diabetes tend to have higher levels of circulating insulin. The ability of the pancreas to increase insulin production means that insulin resistance alone won't have any symptoms at first.

Over time, though, insulin resistance tends to get worse, and the pancreatic beta cells that make insulin can wear out. Eventually, the pancreas no longer produces enough insulin to overcome the cells' resistance.

The result is higher blood glucose levels, and ultimately prediabetes or type 2 diabetes. Insulin has other roles in the body besides regulating blood glucose levels, and the effects of insulin resistance are thought to go beyond diabetes.

For example, some research has shown that insulin resistance, independent of diabetes, is associated with heart disease. Scientists are beginning to get a better understanding of how insulin resistance develops. For starters, several genes have been identified that make a person more or less likely to develop the condition.

It's also known that older people are more prone to insulin resistance. Lifestyle can play a role, too. Being sedentary, overweight or obese increases the risk for insulin resistance.

It's not clear, but some researchers theorize that extra fat tissue may cause inflammation, physiological stress or other changes in the cells that contribute to insulin resistance.

There may even be some undiscovered factor produced by fat tissue, perhaps a hormone, that signals the body to become insulin resistant. Doctors don't usually test for insulin resistance as a part of standard diabetes care. In clinical research, however, scientists may look specifically at measures of insulin resistance, often to study potential treatments for insulin resistance or type 2 diabetes.

They typically administer a large amount of insulin to a subject while at the same time delivering glucose to the blood to keep levels from dipping too low.

The less glucose needed to maintain normal blood glucose levels, the greater the insulin resistance.

Herein, we discuss recent literature suggesting that metformin may inhibit, enhance or have no effect on exercise mediated benefits toward glucose regulation, with particular emphasis on insulin sensitivity.

Therefore, the review identifies gaps in knowledge that require attention in order to optimize medical approaches that improve care of people with elevated blood glucose levels and are at risk of cardiovascular disease.

Insulin resistance comes in degrees. The more insulin resistant a person with type 2 is, the harder it will be to manage their diabetes because more medication is needed to get enough insulin in the body to achieve target blood glucose levels.

Insulin resistance isn't a cause of type 1 diabetes, but people with type 1 who are insulin resistant will need higher insulin doses to keep their blood glucose under control than those who are more sensitive to insulin.

As with type 2, people with type 1 may be genetically predisposed to become insulin resistant, or they may develop resistance due to being overweight. Some research indicates that insulin resistance is a factor in cardiovascular disease and other complications in people with type 1.

While fighting an invisible foe can feel frustrating and discouraging, know that you are not alone. There are effective tactics to combat insulin resistance. Losing weight, exercising more or taking an insulin-sensitizing medication can help you get back to good blood glucose control and better health.

What Can You Do About It? Getting active is probably the best way to combat insulin resistance. Exercise can dramatically reduce insulin resistance in both the short and long terms.

In addition to making the body more sensitive to insulin and building muscle that can absorb blood resishance, physical activity opens up an alternate gateway for glucose to enter muscle cells without insulin acting as an intermediary, reducing the cells' dependence on insulin for energy.

While this doesn't reduce insulin resistance itself, it can help people who are insulin resistant improve their blood glucose control. Weight loss can also cut down on insulin resistance.

No single diet has been proved to be the most effective. Some evidence suggests, though, that eating foods that are low in fat and high in carbohydrates can worsen insulin resistance.

Research has also shown that people who undergo weight-loss surgery are likely to become significantly more sensitive to insulin.

No medications are specifically approved to treat insulin resistance. Yet diabetes medications like metformin and thiazolidinediones, or TZDs, are insulin sensitizers that lower blood glucose, at least in part, by reducing insulin resistance.

Lastly, we hypothesize that combining metformin with exercise may induce cellular processes that regulate metabolic adaptation in relation to glycemia. The other patient suffering from abdominal pain and discomfort, was not willing to try dosage reductions and terminated study participation.

As adolescents with obesity and insulin resistance may be refractory to lifestyle intervention therapy alone, additional off-label metformin therapy is often used. Changes in glucose and insulin parameters, androgen levels, anthropometric measurements, and ovulatory menstrual cycles were evaluated. Jadhav S, Ferrell W, Greer IA, Petrie JR, Cobbe SM, Sattar N.
