Poor lifestyle choices and unhealthy dietary habits have caused serious harm to our health. This is why the risk of conditions ranging from diabetes and heart disease to cancer is rising, even among younger people. Health experts emphasize that to stay protected against illness, it is not enough to simply monitor blood pressure and blood sugar levels; one must also remain vigilant about inflammation within the body.

Chronic inflammation—long-term, persistent inflammation—can damage the body's tissues. It is linked to an increased risk of diabetes, heart disease, fatty liver, and autoimmune disorders. Health experts note that inflammation is not always visible; it can persist inside the body for long periods without any clear symptoms. Over time, this can damage vital organs, with the heart and blood vessels being particularly vulnerable.

A recently published study suggests that hidden inflammation in the body can increase the risk of heart attack and stroke by as much as 43%. Let’s explore how this happens.

The Growing Risk of Heart Attack

Health experts explain that persistent, long-term inflammation can gradually damage the heart, affecting the structure of the heart muscle and its ability to fill with blood. Scientists from the MRC Laboratory of Medical Sciences and Imperial College London revealed this through an analysis that included cardiac imaging, blood tests, and genetic data.

Led by researchers in the UK, the study analyzed health data from approximately 480,000 individuals.
The findings showed that those with the highest levels of inflammation in their bodies faced a 43% greater risk of heart attack and stroke compared to those with the lowest levels of inflammation. Although studies indicate a link between inflammation and heart disease, they do not necessarily prove a direct cause-and-effect relationship in every case.

Why does inflammation in the body increase?

There can be many reasons for an increase in inflammation within the body. Typically, the immune system triggers inflammation in response to an infection or injury, which helps the body heal. However, when this process persists over a long period, it can lead to a state of chronic inflammation. While inflammation is a normal response to injury or infection, persistent inflammation—occurring without an apparent cause—can pose significant health risks.

Obesity—specifically the accumulation of excess fat around the abdomen—is a primary cause.
Additionally, smoking, excessive alcohol consumption, a lack of physical activity, and the frequent intake of sugar and processed foods can increase the risk of inflammation.
Studies have also shown that chronic stress, inadequate sleep, and mental health struggles can further elevate this risk.

Impact on the heart and other organs

Long-term inflammation poses the greatest risk to the heart and blood vessels. It can damage the inner lining of the arteries and accelerate the accumulation of fatty plaque. This can obstruct blood flow and increase the risk of a heart attack or stroke. The impact, however, is not limited to the heart alone.

Persistent inflammation in the brain can increase the risk of neurological issues.
Inflammation in the liver can lead to fatty liver disease and other liver-related conditions.
Chronic inflammation in the kidneys can impair their overall function.
Furthermore, it can contribute to joint pain, swelling, and complications associated with autoimmune diseases.

How can one protect against inflammation?

To prevent chronic inflammation, the most important step is to make improvements to one’s lifestyle and diet. Walking for at least 30 minutes daily, practicing yoga, or engaging in other physical activities can be beneficial.
Include green vegetables, seasonal fruits, whole grains, lentils, nuts, and foods rich in omega-3 fatty acids in your diet.
