Have you ever heard of insulin resistance? It's a term that comes up a lot in discussions about diabetes and obesity, but what does it really mean? Why is it so important for our health? In this article we will explore in depth what insulin resistance is, how it develops, what its symptoms are, and how to prevent it.
Understanding insulin resistance
What is insulin resistance?
Insulin resistance describes a condition in which… Cells become less sensitive to this hormone. Insulin is a hormone produced by the pancreas and plays a crucial role in regulating our functioning Blood sugarthat means we have Blood sugar level. It acts as a key that opens the door for our cells, especially muscle, liver and adipose tissue cells, to allow glucose in.
However, in the case of insulin resistance, this switch no longer works properly. Cells become resistant to the action of insulin and are no longer able to absorb glucose as they should. This leads to the accumulation of glucose in the Blood circulationWhich can eventually lead to type 2 diabetes.
Insulin resistance can also lead to an increase Triglyceride in the blood and a condition known asHyperinsulinemia(1)The body produces more insulin to compensate for cell resistance. In other words, the pancreas starts working Excreted More insulin to try Motivate Cells absorb glucose, but remain insensitive. It's a vicious cycle that can have serious health consequences if insulin resistance is not controlled.
Why do cells become insulin resistant?
There are many factors that can contribute to insulin resistance. Among them are overweight and obesity, a diet rich in fats and sugars, lack of physical activity, smoking and some genetic factors.(2). When a person is overweight, especially around the abdomen, fat cells (fat cells) release substances that can interfere with the way insulin works.
In addition, a diet high in fat and sugar can increase blood glucose levels, which can increase stress on the pancreas and cause it to produce more insulin. Over time, this can overwork the pancreas and make the cells more resistant to insulin(3).
What are the symptoms of insulin resistance?
Insulin resistance is often silent and has no specific symptoms. However, some people may experience signs such as fatigue, excessive hunger, difficulty concentrating, weight gain around the abdomen, and sugar cravings.(4).
These symptoms may be the result of hyperinsulinemia, a condition in which the body produces more insulin to compensate for cell resistance to this hormone. This overproduction of insulin, or secretion Excessive, it can disrupt other metabolic processes in the body, leading to symptoms like those mentioned above.
In addition, a person with insulin resistance may also suffer from it Fasting blood sugar high(5). This means that blood glucose levels remain high even after a period of fasting, usually at night. It is often one of the first signs of insulin resistance and can be detected during a routine blood test.
Finally, insulin resistance may be associated with other health conditions such as polycystic ovary syndrome (PCOS) in women(6)High blood pressure and metabolic syndrome(7).
Diagnosis of insulin resistance
How do you know if you have insulin resistance?
Insulin resistance is usually diagnosed by a doctor using blood tests. These tests measure the level of glucose and insulin in the blood. If your glucose level is high, but your insulin level is also high, this may indicate that your body is producing more insulin to compensate for your cells' resistance to this hormone. This is called hyperinsulinemia, and is an early sign of insulin resistance.
There is also a test called a glucose tolerance test, which measures how your body handles a large amount of glucose. In this test, you drink a drink that contains a large amount of glucose, and then your blood glucose level is measured several times over the next few hours. If your glucose level remains high, this may indicate insulin resistance.
What are the consequences of insulin resistance?
Insulin resistance is a major risk factor for developing type 2 diabetes. In fact, when cells become resistant to insulin, the pancreas must produce more insulin to combat insulin resistance. Maintaining blood glucose levels at approximately normal levels. However, over time, the pancreas can become overwhelmed and no longer able to produce enough insulin. That's when blood glucose levels start to rise, leading to type 2 diabetes.
This condition occurs as a result of a defect in the cells' ability to store sugar efficiently. First, the pancreas can produce more insulin to compensate for cell resistance. This is called This compensation is from the pancreas. However, in the long term, the cells end up not responding to insulin requirements, even in larger amounts.
Insulin resistance can also increase your risk of other health problems, such as cardiovascular disease. In fact, insulin plays a major role in fat metabolism. When cells become resistant to insulin, this can lead to a buildup of fat in the blood, which may increase the risk of cardiovascular disease. This significant accumulation of fat can lead to a Moderately high triglycerides And deposit Fat in the liver.
How to treat insulin resistance?
What are the treatment options?
Treatment of insulin resistance mainly aims to improve the sensitivity of cells to insulin and maintain blood glucose levels at a normal level. This can often be achieved through lifestyle changes, such as losing weight, eating a balanced diet, eating healthy, and getting regular physical activity.
Losing weight is one of the most effective measures to improve insulin sensitivity. In fact, excess weight, especially around the abdomen, is one of the main factors that contribute to insulin resistance. Losing even a small amount of weight can have a significant impact on insulin sensitivity(8).
A healthy diet is also essential for managing insulin resistance. It is recommended to prefer a diet rich in fruits, vegetables, whole grains, lean proteins and healthy fats, while limiting foods high in sugar and saturated fat.
Regular exercise can also help improve insulin sensitivity. This is because when you exercise, your muscles use glucose in your blood for energy, which helps lower your blood glucose levels.(9).
In some cases, medications may be needed to help manage insulin resistance. For example, metformin is a medication commonly used to treat insulin resistance and prevent type 2 diabetes.
How can insulin resistance be prevented?
Preventing insulin resistance depends mainly on adopting a good substance Lifestyle. This includes a balanced diet rich in fruits, vegetables, whole grains, lean proteins and a little Fatty acids saturated and Excess sugar.
Regular exercise is also essential. It is recommended to engage in at least 30 minutes of moderate physical activity most days of the week. This may include activities such as brisk walking, cycling, swimming or gardening.
It is also important to maintain a healthy body weight. If you are overweight or obese, losing a small amount of weight can help improve your insulin sensitivity. In reality, In people who are overweightdanger from Development of some diseases Associated with insulin resistance, such as type 2 diabetes, is higher.
In addition, it is important not to smoke. Smoking can increase the risk of insulin resistance and Onset of type 2 diabetes. If you smoke, talk to your doctor about strategies to help you quit smoking(10).
Finally, it is also necessary to monitor blood glucose levels regularly. High glucose levels can be a Clinical sign Early onset of insulin resistance. If your glucose level is high, your body may compensate for the loss of insulin sensitivity by producing more insulin, which can lead to… Hyperinsulinemia.
What to remember
Insulin resistance is a complex health problem that can have serious health consequences if not managed properly. However, with a good understanding of the condition and a proactive approach to health management, it is possible to live a healthy and fulfilling life despite insulin resistance.
I hope this article has helped you understand insulin resistance better and how to manage it. Remember that your health is in your hands. Give yourself to me !
