Even if you don't have diabetes, has your doctor ever told you that your blood sugar levels are a little high, meaning you're close to developing diabetes? Or are you a little overweight, have high cholesterol, or have high blood pressure? The common cause behind all of this may be this condition called insulin resistance, or ``Insulin Resistance''. Today, let's talk about what this really is, and how it can secretly damage our hearts.
Simply put, what is insulin resistance?
Think about it, the cells in our body are like little houses. These houses need energy to work. That energy comes from the sugar, or `(glucose), that we get from the food we eat. But this sugar can't go directly into the houses called cells. It needs a special key to open the door. That key is the hormone `(insulin)` .
When we eat, our body's pancreas produces a key called insulin. When insulin opens the doors of the cells, the sugar (glucose) in the blood enters the cells and is converted into energy. Then the blood sugar level is controlled at the right level.
Now, look at what happens to someone with insulin resistance. The cells in their body don't respond properly to the key called insulin. It's like the key in a door is stuck. So even though there's insulin, the doors to the cells don't open properly, so the sugar in the blood can't get into the cells. The result is that the blood sugar levels stay high. If this condition continues for a long time, it can develop into diabetes.
But the most dangerous thing is that this not only affects diabetes, but also directly affects the health of our heart.
Why is insulin resistance so bad for the heart?
Did you know that a one-point increase in your blood sugar level (A1c), which measures your average blood sugar levels over the past 2-3 months, can increase your risk of developing cardiovascular disease by about 18%? There are several reasons for this.
1. Damage to blood vessels: When blood sugar levels remain high, it causes inflammation in the inner walls of our arteries. It's like rust eating away at the inside of a pipe. This damage increases the risk of fatty deposits, or plaque, forming in the arteries.
2. Increased bad cholesterol: People with diabetes or insulin resistance may have increased levels of bad cholesterol, especially the very small, dense LDL cholesterol. These can easily build up in damaged blood vessel walls and form plaque.
3. Hardening of blood vessels: High blood sugar levels cause the walls of blood vessels to lose their elasticity and become stiff. This is a major cause of high blood pressure .
4. Nerve damage: This condition also damages the nerves that control the functioning of the heart.
All of these changes combine to cause various diseases in your heart and blood vessels.
What heart diseases can be caused by insulin resistance?
Insulin resistance and diabetes are common causes of heart disease. When plaque builds up in the arteries and blocks them, it restricts blood flow to the heart. This can lead to a variety of symptoms and conditions.
| Medical condition | Simply put... |
|---|---|
| Angina | Chest pain or tightness due to narrowing of the blood vessels leading to the heart. |
| Heart Failure | The heart is unable to pump enough blood to the body. This can cause swelling in the legs, fluid in the lungs, and difficulty breathing. |
| Heart Attack | Complete blockage of a vein that supplies blood to the heart. |
| Stroke | Blockage of a blood vessel supplying blood to the brain. |
| Peripheral Arterial Disease | Narrowing of the blood vessels in the legs. This can cause pain in the legs, especially in the calf area, when walking. |
The best thing is that by identifying these conditions early, controlling blood sugar levels, and seeking necessary treatment, you can control these symptoms and stop the disease from getting worse.
How can you reduce the risk of heart disease now?
The best solution to this is in your hands. With a combination of lifestyle changes and, if necessary, medication taken under medical advice, you can better manage both your blood sugar levels and your heart health.
- Lose weight: Even losing a few kilos of your excess weight can significantly lower your blood pressure and blood sugar levels.
- A heart-healthy diet: Eat more vegetables, fruits, and fiber-rich foods. Reduce your intake of sugar, saturated fat, trans fat, and salt.
- Exercise: Get at least 30 minutes of aerobic exercise, at least 5 days a week. This includes brisk walking, running, and cycling. Even fun things like gardening are good exercise. In addition, do muscle-strengthening exercises at least two days a week. But remember, before starting a new exercise program, you should always ask your doctor if it's right for you.
- Quit smoking, limit alcohol: If you drink alcohol, limit it to less than one serving per day for women and less than two servings per day for men. But if your doctor advises you to cut back even more, stick to that.
- Control your blood pressure and cholesterol: For this too, adopt healthy habits and properly use the medications prescribed by your doctor.
Take-Home Message
- Insulin resistance is not just a sugar problem. It's a serious condition that directly affects your heart.
- Prolonged high blood sugar levels can damage blood vessels, lead to high blood pressure, cholesterol, and ultimately heart disease and stroke.
- Your best defense lies in changing your lifestyle. Healthy eating, exercise, and weight control are powerful weapons.
- Talk to your doctor regularly about your health. Continue to have medical checkups and follow his or her instructions exactly.
