Vascular surgeon with 18 years of experience, shares one simple exercise for people with Peripheral Artery Disease

Peripheral artery disease, or PAD, affects millions worldwide and often leads to excruciating pain, difficulties in walking, and the risk of amputation of a limb in advanced stages. In one remarkable case of how simple lifestyle changes may make a big difference, an exercise recommended by a vascular surgeon helped a young patient with a blockage of critical leg arteries avoid amputation and walk independently. Dr. Sumit Kapadia, a vascular surgeon with 18 years of experience, encountered a patient at risk of leg amputation due to leg artery disease and this is what he recommended-

PAD results from the narrowing or occlusion of the major arteries supplying the limbs due to atherosclerosis. As a result, during activity, the muscles become deprived of oxygen-rich blood, and symptoms include leg pain, cramps, weakness, and fatigue during even short walks. Severe PAD, if left untreated, leads to non-healing wounds and gangrene, which may require amputation. While medical treatments-and surgical options exist, conservative exercise-based methods remain a mainstay in the management and improvement of symptoms and quality of life. PAD can also lead to reduced mobility and overall physical deconditioning, increasing the risk of cardiovascular events such as heart attack and stroke.

Dr. Sumit Kapadia, a vascular surgeon, came across a patient whose legs became weak, painful, and exhausted after only a few steps. Despite ongoing medical care, several doctors had warned of the possibility of amputation. Instead of going for aggressive surgery, Dr. Kapadia recommended a structured program of intermittent walking-an approach gaining powerful clinical support as a way to relieve symptoms in PAD.Intermittent walking consists of walking briskly for a period of two to five minutes, followed by a short rest period, after which this cycle is repeated for as long as one hour per session, several times weekly. This method promotes the growth and dilation of collateral arteries-natural bypass vessels that develop over time to restore blood flow around blockages. By encouraging blood to move through such pathways, intermittent walking improves oxygen delivery to leg muscles and, over time, reduces pain during exercise.At first, progress was slow; the patient could barely make short intervals of walking. But with consistent adherence, his walking endurance increased week by week. The pain that once restricted even minimal movement began to subside. Within weeks-he was able to walk longer distances, climb stairs with reduced discomfort, and regain a degree of mobility previously lost. What at one time was a chore now became a part of daily life as his legs grew stronger, more energized.

For patients with PAD-intermittent walking is not only exercise but also a therapeutic approach. Studies have identified that these walking programs significantly increase pain-free walking distance, reduce symptoms such as leg cramping and fatigue, and enhance functional capacity. Beyond its physical benefits, it empowers patients psychologically by restoring confidence and encouraging independence. Broader implications for the management of PAD The success with this patient’s case underscores how low-cost and accessible interventions can complement medical and surgical care. Although not a substitute for much-needed medical treatments, intermittent walking has been recommended in the guidelines for the management of PAD in many countries. It encourages natural collateral circulation, delaying the progress of the disease and minimizing the possibility of invasive procedures.Physicians and specialists are increasingly-highlighting education regarding walking programs, personalized exercise prescription, and regular follow-up. Patients also benefit from realizing even small, guided steps can translate into significant improvements.This particular case serves as a powerful reminder that tackling complex diseases often paves the way for effective solutions through simple and sustained actions. The practice of intermittent walking exemplifies how we can harness the body’s innate healing abilities to achieve better health outcomes, without the immediate need for surgical interventions. It is crucial for all individuals suffering from atherosclerotic disease accompanied by leg pain to have an open and informative discussion with their healthcare provider regarding these exercise modalities, which should be carefully tailored to their specific medical conditions. With a blend of patience, dedicated guidance, and unwavering commitment, many individuals may discover newfound strength in their legs, experience a significant reduction in pain levels, and cultivate hope for sustained mobility, even in the face of circulatory difficulties. Each step taken not only has the potential to save lives but also plays a critical role in restoring futures for countless individuals.
