U.S.-based cardiologist Dr. Sanjay Bhojraj has warned that heart disease often begins silently decades before symptoms appear. In an Instagram post, he said many people “feel fine” even as their heart struggles due to mitochondrial fatigue, chronic inflammation, and hormonal imbalance. Emphasizing prevention in one’s 30s and 40s, Dr. Bhojraj urged early lifestyle changes to protect heart health, stressing that true prevention starts long before visible signs emerge.

Heart disease has long been considered the result of clogged arteries or bad genes, but a U.S.-based Indian-origin cardiologist says the truth is far more unsettling. Dr. Sanjay Bhojraj, an interventional cardiologist recently shared an eye-opening post on Instagram that’s making many rethink how heart disease truly begins.

The silent danger inside a “healthy” heart

“The scariest part? You can feel ‘fine’ while your heart’s struggling,” Dr. Bhojraj wrote in his post, warning that the real damage often begins decades before symptoms appear. He explained that what’s happening isn’t limited to the arteries but extends deep into the body’s cellular machinery.

According to him, early heart dysfunction stems from mitochondrial fatigue, chronic inflammation, and hormone imbalances—processes that silently weaken the heart for years. By the time fatigue or mild breathlessness shows up, the heart has already been compensating for an underlying crisis.


Why your 30s and 40s matter most

Dr. Bhojraj stressed that prevention is not for your 60s, but for your 30s and 40s, when early lifestyle corrections can still “rewire everything.” At this stage, simple interventions such as maintaining blood sugar balance, improving micronutrient intake, supporting better recovery, and resetting one’s circadian rhythm can protect long-term heart function.

“The heart is incredibly adaptive,” he said, adding that with proper care, it can “regenerate strength, reverse early dysfunction, and even slow cellular aging.”

The message from Dr. Bhojraj is clear: feeling healthy does not always mean being healthy. Many people in their 30s and 40s are unknowingly carrying cellular stress that could evolve into heart disease later in life. As lifestyle disorders surge globally, the cardiologist’s advice serves as a crucial reminder—the fight against heart disease begins long before the first symptom ever appears.
