Can weight loss reverse early heart damage? A cardiologist explains the 5-10% rule

Obesity is "no longer considered a cosmetic matter." It is a long-term disease that silently targets the most essential organ of a person's body — the heart. Excess fat in the body raises blood pressure, disturbs levels of cholesterol, increases blood sugar and instigates chronic inflammation.

Over months and years, these changes fatigue the heart muscle, stiffen arteries and impair the heart. The harm may start well before symptoms are evident. But here’s the bigger reason to feel hopeful – heart damage can often be slowed and sometimes partially reversed with significant weight loss in its early stages.

Effects of Being Overweight on Heart Health

When there is excess weight in the body, it's not only the extra body mass that the heart has to supply blood to, but the heart has to work harder to pump blood around the body, too.

This extra workload all the time can make the heart muscle thicker called left ventricular hypertrophy. They may also become stiffer, raising the risk for hypertension and heart disease.Obesity is also associated with insulin resistance, which predisposes to type 2 diabetes yet another major risk factor for heart problems. Extra belly fat also emits inflammatory compounds that erode the linings of blood vessels and speeds up plaque formation.

This result up to an increased risk of heart attack, stroke, and heart failure, which are often silently brewing for years.

The Benefits of Losing 5 to 10%

The evidence is strong that a modest amount of weight loss 5 to 10 percent of total body weight can have a big impact on cardiovascular health.When people lose weight: It can bring blood pressure down.‘Bad’ LDL cholesterol goes down.Blood sugar gets better.Inflammation subsides.Less work for the heart.In the early stages of heart strain, such changes can make the heart muscle work better.

Changes In Lifestyle That Can Make A Difference

The secret is not crash dieting but long-term change. A heart-healthy diet is high in fruits, vegetables, whole grains, lean proteins and healthy fats that work together to help repair the cardiovascular system. Regular exercise even a 30-minute walk a day can strengthen your heart and help your circulation.Getting enough sleep, managing stress, and not smoking are just as crucial.

Sometimes professional supervision for medical treatments or structured weight management programs may be appropriate.

Prevention Is Better Than Cure

Early heart damage may be reversible with weight loss, but severe heart disease is not. That’s why early action is important. Testing for blood pressure, blood sugar, cholesterol levels, and body mass index (BMI) can identify risks before problems arise.Main message on World Obesity Day Keep moving – Healthy Weight equals a Healthy Heart!Your heart is incredibly resilient.
