Exercise as a therapy for progressive diseases

By Mujahid Nasir Hussain

On 14 November 2025, the world marked World Diabetes Day, and a familiar message rang out across hospitals, communities, and workplaces: Africa must “know more and do more” to confront the rising tide of chronic diseases. It is a message that feels especially urgent here in Nigeria, and in cities like Kano, where the realities of modern life have dramatically reshaped how people live, move, work, and stay healthy. For many families, this year’s theme was not merely a global campaign. It reflected what they witness daily—more people living with diabetes, hypertension, kidney disease, stroke, obesity, and joint disorders than ever before.

The World Health Organisation has warned that Africa will soon face a dramatic shift in its health landscape. By 2030, deaths from non-communicable diseases are projected to surpass those from infectious diseases. This is a striking transformation for a continent historically burdened by malaria, tuberculosis, and HIV. Nigeria, Africa’s most populous nation, is at the centre of this shift, with cities such as Kano experiencing a rapid rise in chronic and progressive conditions. The reasons are both complex and straightforward: changing diets, prolonged sitting, stressful work environments, reduced physical activity, environmental pollution, and limited access to preventive healthcare.

Yet amid these alarming trends, one therapeutic tool stands out: exercise. For many years, exercise has been treated merely as a wellness activity or an optional lifestyle choice. But in reality, it is one of the most powerful and scientifically proven therapies for slowing the progression of chronic diseases. When the body moves consistently, it undergoes profound biological changes: insulin works better, blood vessels become healthier, the heart becomes stronger, inflammation decreases, and harmful fat around organs begins to shrink. These benefits are not cosmetic; they are therapeutic.

However, there is a critical truth that the public often misunderstands: exercise is powerful medicine, and like any medicine, it must be prescribed correctly. It is not something people with chronic diseases should “start doing” without guidance. The mode, frequency, intensity, and duration of exercise must be tailored to the individual’s medical condition, age, fitness level, and risk factors. What is safe and effective for one person may be dangerous for another. This is why professional guidance is so essential. For instance, a person living with uncontrolled hypertension should not begin intense aerobic workouts without clearance from a doctor, because sudden spikes in blood pressure could lead to complications.

Someone with diabetic neuropathy may not feel injuries in their feet, making certain activities unsafe without supervision. Individuals with chronic kidney disease need specific exercise prescriptions that do not strain the cardiovascular system or accelerate fatigue. People recovering from stroke require structured rehabilitation overseen by physiotherapists to prevent falls or further damage. Even patients with obesity, osteoarthritis, or long-standing back pain need tailored, gradual programs to avoid joint overload. This is why exercise should not be approached casually, especially in a context like Africa, where many chronic conditions are undiagnosed or poorly monitored. Before starting an exercise program, individuals living with progressive diseases should consult qualified professionals. Doctors provide medical clearance and identify risks. Physiotherapists design safe movements that protect joints and nerves. Exercise physiologists prescribe evidence-based routines that align with the patient’s goals and limitations. Their role is to ensure that exercise becomes therapy, not a trigger for complications.

In Kano State, this issue is especially relevant. The city has undergone a rapid transition from physically demanding lifestyles to sedentary routines. Many residents now spend long hours sitting in shops, riding motorcycles, or working in offices. Combined with high consumption of energy-dense foods and limited awareness of disease symptoms, progressive illnesses have become deeply entrenched. Yet awareness of safe, guided exercise therapy remains low. Many people begin rigorous routines abruptly, driven by social pressure or misinformation, only to injure themselves or exacerbate their conditions. Others avoid exercise entirely because they fear doing the wrong thing. Both extremes are harmful.

To confront this, a cultural shift is needed, one that recognises exercise as a vital part of medical care. Hospitals and clinics across Nigeria must integrate exercise counselling into routine visits, especially for patients with diabetes, hypertension, kidney issues, and obesity. Something as simple as a doctor explaining which movements are safe, or a physiotherapist demonstrating gentle routines, could prevent years of complications. Exercise physiologists, though still few in number, should be incorporated into more healthcare teams to design personalised programs grounded in scientific evidence.

At the community level, awareness must grow that exercise therapy is not a one-size-fits-all approach. It is a carefully structured health intervention. Encouraging early-morning walking groups, promoting workplace movement breaks, and organising community fitness sessions are valuable, but they must be paired with safety education. Leaders—traditional, religious, and educational—can play a vital role by emphasising the importance of seeking professional guidance before starting any intense routine, especially for those already living with chronic diseases.

It is also worth acknowledging the emotional dimension. People battling progressive diseases often feel overwhelmed, frightened, or uncertain. Exercise offers not just physical healing but a sense of agency. It improves mood, relieves anxiety, supports sleep, and helps people feel that they are actively shaping their health. This psychological benefit is powerful, especially in societies where chronic diseases still carry stigma. But again, confidence grows stronger when people know they are exercising safely and correctly under the guidance of trained professionals.

Nigeria’s future health outcomes depend on coordinated action. Families must embrace a culture of safe movement. Workplaces must reduce prolonged sitting and encourage healthy routines. Schools must restore physical activity as a normal part of the day, not an afterthought. Healthcare institutions must treat exercise as a formal therapy, not a casual suggestion. And individuals must understand that professional guidance is the foundation of safe and effective exercise therapy. The WHO’s projections are indeed alarming, but they are not destiny. Africa still has the opportunity to change its trajectory. But to do so, we must shift how we view health, how we integrate movement into daily life, and how we approach treatment of chronic diseases. Exercise will play a central role in this transformation, but only if it is approached with the same seriousness and medical supervision as any other form of therapy.

In the markets of Kano, the offices of Abuja, the streets of Lagos, and the rural communities of northern and southern Nigeria, the message must be clear: movement heals, but only when guided, intentional, and safe. The global call to “know more and do more” continues beyond 14 November. This is a reminder that Africans must not only embrace exercise as therapy but also do so with professional guidance to protect the body and preserve long-term health. Our path forward lies not just in treating disease, but in transforming lifestyles with knowledge, with care, and with the understanding that the right kind of movement, at the right intensity, prescribed by the right professional, can change the story of health for a generation.

US-based Nigerian scholar Dr Fahad Usman develops innovative, non-invasive method for diabetes testing

By Uzair Adam

In a ground-breaking advancement for diabetes diagnostics, Nigeria-born Dr Fahad Usman, an Assistant Professor of Optical Engineering Technology in the United States, has introduced a highly sensitive optical biosensor capable of non-invasive diabetes screening.

Dr Usman’s pioneering work focuses on a surface plasmon resonance (SPR) biosensor that detects exhaled breath acetone, a key biomarker for diabetes. This innovative approach offers an alternative to traditional blood glucose tests, which are invasive and often painful.

Dr Usman’s research, published in top journals like Results in Physics and Polymers Journal, presents a novel ternary composite material made from polyaniline, chitosan, and reduced graphene oxide. With enhanced electrical conductivity and thermal stability, this material underpins the SPR biosensor, allowing it to detect acetone concentrations as low as 0.88 parts per billion. 

This collaboration with researchers from Malaysia, France, Saudi Arabia, and the U.S. addresses the global diabetes crisis. With over 537 million affected worldwide and projections of 783 million by 2045, this innovation promises a significant impact. According to the National Institutes of Health, over 37 million people in the U.S. are affected by diabetes. 

Due to its non-invasive nature, the optical sensor ensures greater accuracy, sensitivity, and reliability and enhances patient compliance. 

Dr Usman’s work represents a significant leap forward in healthcare innovation. It positions the U.S. at the forefront of global scientific advancements.

This technology offers potential beyond healthcare, with broader industrial applications in optical sensing and materials science.

Diabetes week 2024: Understanding, preventing and managing a global health challenge

By Mujahid Nasir Hussain

Diabetes Week is an annual event dedicated to raising awareness about diabetes and encouraging prevention and management strategies to support those living with the condition globally. As the world comes together for Diabetes Week 2024, observed from June 10th to 16th, communities, healthcare professionals, and organizations united in a series of events and campaigns to foster a deeper awareness and a proactive approach towards combating the condition.

According to the 2024 International Diabetes Federation (IDF) report, diabetes is a significant and growing global health issue affecting diverse regions and populations. Approximately 537 million adults (20-79 years) worldwide are living with diabetes, with this number expected to rise to 643 million by 2030 and 783 million by 2045. One of the major concerns regarding this increase is that Nigeria is among the countries facing such a significant rise, with current estimates showing millions affected and a substantial proportion of cases undiagnosed. Thus, there is a need for improved diabetes education, prevention programs, and accessible treatment options to combat this growing health crisis.

Diabetes is a chronic condition characterized by high blood glucose levels. This occurs when the body either doesn’t produce enough insulin or cannot effectively use the insulin it produces. Persistent high blood glucose can damage various organs and systems, leading to significant health complications. Although there are many forms of diabetes, according to numerous literature reports, there are generally three. Viz: Type 1 diabetes, Type 2 diabetes and Gestational diabetes.

Type 1 Diabetes

Type 1 diabetes is an autoimmune condition where the body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. This destruction leads to little or no insulin production, crucial for regulating blood sugar levels. Individuals with Type 1 diabetes require lifelong insulin therapy, either through injections or an insulin pump, to manage their blood glucose levels. This type of diabetes often manifests in childhood or adolescence but can occur at any age. Symptoms include excessive thirst, frequent urination, unexplained weight loss, extreme fatigue, and blurred vision.

Type 2 Diabetes

Type 2 diabetes is the most common form of diabetes, accounting for about 90-95% of all diabetes cases. It occurs when the body becomes insulin resistant, or the pancreas fails to produce enough insulin. This condition is often associated with lifestyle factors such as obesity, physical inactivity, and poor diet. Risk factors also include age, family history, and certain ethnic backgrounds. Symptoms are similar to Type 1 diabetes but may develop more slowly, making early detection and management crucial. Lifestyle changes, oral medications, and sometimes insulin therapy are used to manage Type 2 diabetes.

Gestational Diabetes

Gestational diabetes occurs during pregnancy when the body cannot produce enough insulin to meet the extra needs of pregnancy. This condition typically resolves after childbirth but increases the mother’s risk of developing Type 2 diabetes later in life. Gestational diabetes can lead to complications such as high birth weight, preterm birth, and increased risk of cesarean delivery. Managing gestational diabetes involves a healthy diet, regular physical activity, and monitoring blood sugar levels. In some cases, insulin therapy may be needed.

Diabetes Complications

Unmanaged diabetes can lead to severe and potentially life-threatening complications, emphasizing the importance of effective management. These complications include:

Cardiovascular Disease: People with diabetes have a higher risk of developing heart disease and stroke due to damaged blood vessels and nerves.

Neuropathy: High blood sugar levels can damage nerves, especially in the legs and feet, leading to pain, tingling, and even loss of sensation. Severe cases can result in foot ulcers and amputations.

Nephropathy: Diabetes is a leading cause of kidney disease, which can progress to kidney failure, requiring dialysis or a kidney transplant.

Retinopathy: High blood sugar can damage the blood vessels in the retina, leading to vision problems and even blindness.

Skin Conditions: Diabetes can make individuals more prone to bacterial and fungal infections and other skin disorders.

Treatment Strategies for Diabetes

Effective diabetes management requires a multi-faceted approach that includes lifestyle changes, medication, regular monitoring, and education & support.

Lifestyle Modifications: Adopting a balanced diet rich in fruits, vegetables, whole grains, and lean proteins while reducing intake of processed foods and sugary beverages. Regular physical activity, such as walking, cycling, or swimming, is essential to help maintain a healthy weight and improve insulin sensitivity.

Medication: Treatment depends on the type of diabetes. For Type 1 diabetes, insulin therapy is essential. For Type 2 diabetes, oral medications like metformin or other hypoglycemics may be prescribed, and in some cases, insulin may be required.

Monitoring: Regular blood glucose monitoring ensures levels remain within the target range. Continuous glucose monitors (CGMs) provide real-time data, allowing for better management and adjustment of treatment plans.

Education and Support: Diabetes education programs help individuals understand their condition, make informed decisions about their care, and provide emotional support. Support groups offer a platform to share experiences and coping strategies.
