While exercising regularly is known to reap several health benefits, it’s also important to consider your blood pressure, blood sugar, and general health before starting a fitness journey.  While lifting weights, breaking a sweat, and feeling fitter week by week, is exciting, understanding what’s happening inside your body before intense workouts is just as important as the workouts themselves.

It’s not just about muscles or stamina. Dr Bhanu Mishra, Consultant Nephrologist, Fortis Hospital, Shalimar Bagh, Delhi, warns, “Your kidneys, heart, blood sugar, and general health determine how well your body can cope with physical stress, stay hydrated, and produce energy. Ignoring this could lead to hidden issues that only show up when it’s too late. Dr Mishra says, “The kidneys are your body’s natural filters. They flush out toxins, balance electrolytes, regulate blood pressure, and help manage hydration, all crucial when you’re exercising hard.”

When your muscles work, they produce waste that your kidneys need to clear efficiently. Dr Mishra explains, “If your kidneys aren’t working optimally because of undiagnosed conditions like diabetes, high blood pressure, or dehydration, a tough workout or extra protein could put them under serious stress.”

Checking your general health is about knowing your bodies boundaries. “A simple health screening, looking at kidney function, blood pressure and heart health can uncover hidden issues. High intensity workouts might be risky if you have an unknown heart condition, and anaemia can leave you exhausted, even during simple exercises.” he says. Knowing your body well can help you tailor a better fitness plan that supports your health and not work against it.
