Have you ever heard of high blood sugar levels, or the conditions that precede diabetes? Well, there's a condition called Hyperinsulinemia that's related to the hormone insulin that our bodies produce, but we probably don't talk about it much. Don't worry, we'll talk about it simply, in a way that you can understand.
What is this (Hyperinsulinemia)? To put it very simply...
Hyperinsulinemia is when you have more insulin than normal in your blood. So, what is insulin? It is a very important hormone produced and secreted by our pancreas. It helps to control the level of glucose (sugar) in our blood, especially glucose.
Most of the time, hyperinsulinemia is caused by a condition called insulin resistance . This is when your muscle, fat, and liver cells don't respond properly to insulin. When this insulin resistance occurs, your body responds by producing more insulin in an attempt to keep your blood sugar levels healthy. This is when hyperinsulinemia occurs.
Imagine that a person has too much insulin in their body, but they do not have insulin resistance. If that happens, their blood sugar levels may drop, causing a condition called hypoglycemia . However, in hyperinsulinemia, which is caused by insulin resistance, the excess insulin does not lower their blood sugar levels.
However, if this insulin resistance and hyperinsulinemia persist, it can lead to a condition called hyperglycemia, where blood sugar levels remain high. This is the primary cause of prediabetes and type 2 diabetes later on.
Important: (Hyperinsulinemia) and (Hyperinsulinism) are two different things!
Many people confuse the two conditions because of the similarity in their names. Hyperinsulinism is a different condition. It is caused by a problem in the pancreas that causes an increase in insulin in the blood. This can be caused by a tumor that produces too much insulin (called an insulinoma), or by a genetic mutation that is present in the body. Unlike hyperinsulinemia, hyperinsulinism causes low blood sugar (hypoglycemia).
Who is most likely to be affected by this condition (Hyperinsulinemia)?
Hyperinsulinemia, caused by insulin resistance, can affect anyone. It can be temporary or long-term. There are two main factors thought to contribute to this:
1. Excess body fat: Extra fat, especially around your belly.
2. Lack of physical activity: This means a lack of exercise.
How common is hyperinsulinemia?
Since there is no specific test to detect hyperinsulinemia, and insulin resistance does not cause any major symptoms until it progresses to prediabetes or type 2 diabetes, it is difficult to say exactly how common it is. However, we can get an idea of how many people have prediabetes. Millions of adults worldwide have prediabetes. This means it is a more common problem than you might think.
How does hyperinsulinemia affect my body?
In addition to prediabetes and type 2 diabetes, hyperinsulinemia is also associated with the following conditions:
- Obesity: This means being extremely fat.
- Metabolic Syndrome: This is a collection of several related symptoms.
- Polycystic Ovary Syndrome (PCOS): A hormonal imbalance that commonly affects women.
- Elevated triglyceride levels: These are a type of fat found in the blood.
- Increased uric acid levels: This can lead to conditions like gout.
- Atherosclerosis: This increases the risk of heart disease.
- Hypertension: This means increased blood pressure.
What are the symptoms of (Hyperinsulinemia)?
Hyperinsulinemia, which is caused by insulin resistance, may not cause you any obvious symptoms. This is because your pancreas can produce enough insulin to overcome the resistance. However, ongoing insulin resistance and hyperinsulinemia can lead to prediabetes and type 2 diabetes.
Many people may not show symptoms of prediabetes for years. However, some people may experience symptoms such as:
- Darkening of the skin on the armpits, back of the neck, and sides: This is called `(Acanthosis Nigricans)`. It looks like dirt, but it's not dirt.
- Skin tags: Some people also call these skin tags.
- Eye changes: These can later progress to diabetic retinopathy, a condition in which the eyes are damaged by diabetes.
The symptoms of Type 2 Diabetes are:
- Excessive thirst.
- Frequent urination.
- Excessive hunger.
- Blurred vision.
- Headache.
- Vaginal and skin infections.
- Delayed wound healing.
If you have one or more of these symptoms, it is very important to see a doctor immediately.
What are the causes of hyperinsulinemia?
We now know that the main cause of hyperinsulinemia is insulin resistance . When you have insulin resistance, your body doesn't use insulin properly, so your pancreas has to produce extra insulin in an attempt to keep your blood sugar levels healthy.
How to diagnose (Hyperinsulinemia)?
Hyperinsulinemia can be a bit tricky to diagnose, as it doesn't show symptoms until it's advanced to prediabetes or type 2 diabetes. There's also no common test to accurately measure insulin levels in the blood, as insulin levels can fluctuate greatly throughout the day.
Therefore, since there is no single test that can directly diagnose hyperinsulinemia, your doctor will consider several factors when assessing this condition:
- Your medical history: things like previous illnesses and medications you've taken.
- Family medical history: Does anyone in the family have conditions like diabetes?
- Physical examination.
- The symptoms you are showing.
- Blood test results: For example, fasting plasma glucose (FPG) test.
How is hyperinsulinemia treated?
Because not all factors that contribute to hyperinsulinemia (e.g., genetic factors, age) can be treated, lifestyle changes are the main treatment. These lifestyle changes include:
- Diet:
- Your doctor or nutritionist may advise you to limit foods high in carbohydrates (e.g. rice, bread, noodles, potatoes, and sweets) because these stimulate insulin production.
- It also says to reduce unhealthy fats, sugar, red meat, and processed starches .
- Instead, it's recommended to eat a whole foods diet that's high in vegetables, fruits, whole grains, fish, and lean poultry . Think of it like sharing a plate of rice, reducing the amount of rice and adding more vegetables, legumes, and herbs.
- Exercise:
- Exercise reduces insulin levels and gradually increases insulin sensitivity. This helps treat hyperinsulinemia. It is great if you can do something like walking, running, or cycling for at least 30 minutes a day.
- Weight loss:
- Losing weight can help improve the condition (Hyperinsulinemia). On the other hand, gaining weight can make this condition worse.
- Hyperinsulinemia can also improve when obesity is treated with lifestyle changes, diet, medication, or bariatric surgery (this is surgery to reduce obesity).
For people with severe obesity who undergo bariatric surgery, hyperinsulinemia improves rapidly within a week of surgery. Insulin sensitivity also improves between 6 and 24 months after surgery. However, this surgery is not suitable for everyone. Talk to your doctor about which treatment options are right for you.
Can hyperinsulinemia be reversed?
There are several causes and factors that contribute to insulin resistance (i.e., hyperinsulinemia). Lifestyle changes such as eating a healthy diet, exercising regularly , and losing excess weight can help improve insulin sensitivity and reduce insulin resistance and hyperinsulinemia. That means, yes, it can be controlled to a large extent, and sometimes even reversed! However, not all causes can be reversed (e.g., genetic influences).
It's best to talk to your doctor about what you can do to best manage your insulin resistance and hyperinsulinemia.
What are the risk factors for developing hyperinsulinemia?
Certain genetic and lifestyle risk factors can increase your risk of developing hyperinsulinemia. These risk factors include:
- Being overweight or obese: Having excess fat, especially around the belly.
- Age 45 years or older.
- Having a close family member (parent or sibling) with diabetes.
- Living a sedentary lifestyle with little physical activity.
- Having health conditions such as high blood pressure and abnormal cholesterol levels.
- Having had a previous heart attack or stroke.
- Having sleep-related problems such as sleep apnea.
- Smoking.
What is the prognosis of hyperinsulinemia?
The outlook for hyperinsulinemia, that is, how the condition will develop, depends on several factors:
- Insulin Resistance: This is the primary cause of hyperinsulinemia.
- The severity of insulin resistance and hyperinsulinemia.
- How susceptible you are to secondary complications that can occur due to insulin resistance and hyperinsulinemia.
- How well you adapt to treatment and how your body responds to it.
Some people can have mild insulin resistance and hyperinsulinemia, without ever progressing to prediabetes or type 2 diabetes. Also, some people can reverse or manage insulin resistance and hyperinsulinemia with lifestyle changes.
However, if you develop Type 2 Diabetes due to Hyperinsulinemia, you should try your best to manage the condition well to avoid possible complications.
When should I see a doctor about hyperinsulinemia?
If you have been diagnosed with hyperinsulinemia or conditions related to insulin resistance, it is very important to see a doctor regularly to make sure your blood sugar levels are at a healthy level and that your treatment is working.
If you have symptoms of high blood sugar (the ones we discussed earlier) or symptoms of prediabetes, see your doctor right away. They can do simple tests to check your blood sugar levels.
Hyperinsulinemia is a potentially harmful condition. It is often the result of insulin resistance. Since it does not show symptoms until it progresses to prediabetes or type 2 diabetes, the best thing you can do is maintain a healthy weight, exercise regularly , and eat a healthy diet. These things can help prevent and reverse insulin resistance and hyperinsulinemia.
The most important things we need to remember (Take-Home Message)
Okay, so I hope you now have a good idea about what we've been talking about (Hyperinsulinemia). In summary:
- Hyperinsulinemia is an increase in insulin in the blood, often caused by insulin resistance.
- Although this may not show any symptoms at first, it can later lead to prediabetes and type 2 diabetes, as well as a host of other health problems.
- A healthy lifestyle (good diet, exercise, weight control) is the best shield and the best medicine for this.
- If you have risk factors or feel like you have any symptoms, don't hesitate to see a doctor. If it's detected early, it's much easier to control.
Remember, your health is in your hands. Small changes can make a big difference!
