Insulin resistance — also called syndrome X — is so pervasive today but many women are still taken aback when they learn they either already have insulin resistance syndrome (some are even pre-diabetic) or are well on their way to developing it. Experts estimate that 25% of all Americans suffer from insulin resistance. We believe the percentage is much higher among perimenopausal women.

Because insulin is one of the “major” hormones, it’s also impossible for your body to balance its “minor” hormones (estrogen, progesterone and testosterone among them) until your insulin metabolism is balanced first. To put it simply, if you have hot flashes and you are insulin resistant, it’s going to be nearly impossible to cure the hot flashes without first healing the insulin resistance. (Cortisol is also a “major” hormone; to understand its role in hormonal balance, read our related article on adrenal imbalance.)

The good news is that you can heal insulin resistance. Let’s explore natural healing methods and how they might help you.

The link between insulin resistance and chronic disease

Over 80 million Americans suffer from insulin resistance, and it appears to sit at the center of a web of related health problems. Women who are insulin resistant are at much greater risk of obesity, diabetes, hypertension (high blood pressure), heart disease, high cholesterol, breast cancer and polycystic ovarian syndrome (PCOS). There is some evidence that insulin resistance may contribute to endometrial cancer. It has also been implicated in Alzheimer’s disease.

Insulin resistance often accompanies the most common complaints we hear at Women's Health Network — fatigue and weight gain. As women approach menopause, they become increasingly intolerant of carbohydrates and find it easier to gain weight, especially around their waists. Afternoon blahs, sugar crashes and carbohydrate cravings may all be early insulin resistance symptoms.

Insulin sensitivity — the way it should work

All of the food we eat — fats, proteins and carbohydrates — is broken down during digestion into proteins, micronutrients and glucose. The body uses the proteins and nutrients in cellular metabolism, immune function, and cell replacement. The body uses glucose as its basic fuel, which is carried by the bloodstream to individual cells.

Our demand for fuel varies from moment to moment, but the brain needs our blood sugar level to remain stable. So getting the cells the energy they need without changing that level is a critical function — and that’s the role that insulin plays. Insulin signals the cells to absorb glucose from the bloodstream. The body monitors what we’ve digested, blood sugar levels, and cell demands, and releases insulin in just the right amounts. That’s why a healthy body is described as “insulin sensitive.”

Insulin: sensitive is good

Our metabolism evolved eons ago, when our diet included fewer (and more complex) carbohydrates. Today most calories in an average diet come in the form of carbohydrates, and most of those are simple carbohydrates — sugars that quickly enter the bloodstream. The body has to release high levels of insulin to keep the level of glucose in the bloodstream from spiraling out of control. But in time the cells quit responding to this signal. At this point the body is “insulin resistant.”

One immediate consequence is that the body is forced to release even more insulin. Letting blood sugar get too high is simply not acceptable. The resulting excess of insulin in the bloodstream is called hyperinsulinemia. But the body wasn’t designed for these prolonged high levels of insulin, which disrupt cellular metabolism and spread inflammation. Diabetes occurs when the body is unable to keep blood glucose under control. But as we have noted, that is only the most obvious disease caused by insulin resistance. There are many negative health effects before full-blown diabetes.

Syndrome X and menopause

Of special concern to women is how insulin resistance disrupts fat metabolism. When the cells won’t absorb the extra glucose, the liver has to convert it into fat. Fat cells are loaded with glucose receptors, so this is a vicious cycle. Ironically, while the insulin-resistant woman is gaining weight, her cells are actually “starved” for glucose, so she feels exhausted and tends to eat carbohydrate-heavy foods in search of energy.

These extra fat cells are also little estrogen factories. So weight gain contributes to the estrogen dominance that causes so many symptoms during the early stages of perimenopause.

Symptoms relating to syndrome X usually predate the onset of menopause, but most women do not complain of them until then. A woman’s health can deteriorate rapidly during menopause with the decrease of estrogen levels in the body. And digestive issues that were once merely a hassle become an affliction when the body’s natural defenses against inflammation (estrogen being one) are depleted.

In addition, women approaching menopause are particularly prone to becoming insulin resistant due to metabolic changes related to fluctuations in adrenal and thyroid secretions. In fact, the decrease of certain hormones, like estradiol, may trigger a resistance to insulin in women who never experienced it before. Certain blood pressure medications can mask symptoms without treating the problem. Frequently, women unwittingly make their symptoms worse by trying to lose weight with low-fat, high-carbohydrate diets.

How do I know if I’m insulin resistant?

The unfortunate truth is that anyone can become insulin resistant — even if she is thin because we have access to a lot of refined carbohydrates (white bread, sugar, bagels, pasta, potatoes, sodas, processed foods with added fructose, etc.). In fact, most of us are likely to be somewhat resistant to insulin. It is just a matter of degree. The more processed and refined food that we eat, the more insulin we require to metabolize it. The more insulin in our blood, the less responsive our cells become. As we age, this continual exposure wears out our tolerance for refined carbohydrates and reduces our sensitivity to insulin.

If you suffer from high cholesterol, high triglycerides, or hypertension, you should get checked for insulin resistance, regardless of your weight or age. If you have high blood pressure, it is likely that you are also suffering from insulin resistance. High blood pressure medication will not cure insulin resistance.

Signs and symptoms of insulin resistance

You are at the highest risk for developing this condition if you have a family history of type 2 diabetes or if you have suffered from gestational diabetes, hypertension, or are seriously overweight.

Apple-shaped women, or those who tend to gain most of the weight around their abdomen, show less tolerance for insulin. To assess your risk, measure yourself around the smallest part of your waist (don’t hold your stomach in!) and the biggest part of your hips. Divide the waist measurement by the hip measurement. A ratio bigger than 0.8 for women (or 1.0 for men) indicates that your abdomen is obese and you are at risk for developing insulin resistance.

Women with an abnormal amount of fat or cholesterol in the blood, or dyslipidemia, especially those with low HDL levels and high triglycerides, may also be resistant. A skin change called acanthosis nigricans, which is warty-like darkened patches of skin at the neck and armpits, indicates insulin resistance in over 90% of the women who experience it.

The good news is that insulin and glucose levels are very easily influenced by changes in lifestyle, exercise, diet and supplementation. If you are diagnosed with insulin resistance, there is a lot you can do to reverse its course.

Bringing insulin into check

At Women's Health Network, we understand that insulin resistance may be an underlying factor in a range of health problems. Our goal at Women's Health Network is to enable all women to feel energetic, lively, attractive, passionate, and excited for years to come, as opposed to feeling lethargic, irritable, and hormonally imbalanced. Thankfully, there's a lot can be done to decrease women's insulin sensitivity and bring their hormones back into natural balance.

To evaluate insulin resistance, a blood test for glucose and insulin levels after fasting for 12 hours and then again two hours after a meal (preferably a high-carbohydrate meal) is healpful. On the fasting tests, it's best to see glucose levels of no more than 75–80 and Dr. Sharon Stills likes to see insulin at around 5; higher levels indicate a risk of insulin resistance. Increased triglycerides can help confirm a diagnosis within this context. If the triglycerides amount to about half of the cholesterol number, it indicates proper metabolism of fat. For example, if total cholesterol is 200, then triglycerides should be 100. You should also take into account your lifestyle, diet and exercise patterns, as well as stress factors. All of this can be changed.

Talk to your primary care provider about being tested if you feel you are at risk. Many younger practitioners are familiar with the concept of insulin resistance, as it is now being taught in medical school. Unfortunately, old-school physicians may still be unaware of its importance.

Insulin resistance diet

A diet that consists primarily of lean meats and other proteins; high-fiber grains, vegetables and legumes; leafy greens; and fruit will substantially aid the body’s ability to balance insulin levels. If a woman is already insulin resistant, we recommend a meal plan consisting of breakfast, lunch, dinner, and two snacks. Each meal should have no more than 15 grams of carbohydrates in the form of vegetables and fruits (and prohibiting “white” food altogether, such as bread, pasta, and sugar) and some lean protein. Each snack should contain only 7 grams of similar carbohydrates.

Healthy fats, or those rich in essential fatty acids (EFA’s), are also important in an insulin-resistance diet. EFA’s can be found in avocados, cold-water fish like salmon and tuna, flax seed, and eggs and can also be taken in supplement form.

We also highly recommend a pharmaceutical-grade nutritional supplement, which can help decrease carbohydrate and sugar cravings and normalize the hormonal function in menopausal and perimenopausal patients. The Hormonal Health Packages will satisfy the body’s nutritional demands in relation to insulin sensitivity.

Regular exercise of 30 minutes or more per day, 3–5 times a week is also beneficial for regulating metabolic function and hormonal balance. Decreasing stress, thereby lessening strain on the adrenal glands, will result in better overall health and contribute to keeping the body’s insulin levels in check. Stopping smoking, moderating alcohol intake, and encouraging proper sleeping habits will help alleviate blood chemistry surges, which in turn will promote a thriving, well-balanced body.

Your body’s hormonal balance is like a symphony. Insulin is one of the loudest and most important instruments. When its metabolism goes wrong, it throws off everything else. We’ve seen over and over how women with menopause symptoms must reverse their insulin resistance in order to find relief from other symptoms. It can be done, and we’re here to help.
