by Professor Sunil Wimalawansa, MD, PhD, MBA, DSc. Professor of Medicine The fundamental difference between males and females is that males typically have XY chromosomes.

by Prof Sunil J. Wimalawansa Considering what has happened over the past few decades, it is no surprise that people do not want to see disruptive politicians who once governed the country returning to power. This sentiment is reflected in the over 4.7 million voters (out of 6.9 million) who previously voted for the former […]

By Prof. Sunil J. Wimalawansa Despite massive failures over the past 76 years, many middle-class Sri Lankans—the majority in Sri Lanka- still believe that only family-driven, self-claimed, high-class politicians can run the country. Clans, which have controlled the country for the past four decades, have failed to uplift society and its people socially, morally, and […]

Professor Sunil J. Wimalawansa Sri Lanka is at a critical junction in moving into the right recovery path or going down further to compete with other sunken countries. During economic crises, hunger becomes more prevalent, driven by the inability to afford basic needs like food due to unemployment, lack of savings, and limited resources like […]

by Prof. Sunil Wimalawansa, MD, PhD, MBA, DSc., Prof of Medicine The current political landscape in Sri Lanka is fraught with issues that render the existing politicians unsuitable for the presidency. How can people trust members of parliament who become politicians purely to make money, sell their duty-free car permits, and abuse power? Honesty, integrity, […]

by Dr. Sunil Wimalawansa, MD, PhD, MBA, DSc., Prof of Medicine With misplaced priorities, the caretaker government continues to make significant financial and policy errors that harm the country.

by Drs. Sunil J. Wimalawansa (Prof. of Medicine)and Chandra B. Dissanayake (Prof. of Geology) Since identifying chronic kidney disease of unknown etiology (CKDu) in Sri Lanka in the mid-1990s, little progress has been made in aetiology and prevention. Despite the numerous hypotheses and conjectures—with more than 35—none have been thoroughly studied or substantiated as the […]

Prof. Sunil Wimalawansa  Part Five: Vitamin D safety and adverse effects—When should caution be advised?   In hypovitaminosis D, maximum benefit occurs over a steep dose response. Beyond that, no matter the high doses, additional benefits won’t exist. This principle is crucial for designing Clinical Studies and RCTs and Practice (DOI: 10.3390/biomedicines11061542)  It provides original links to […]

Professor Sunil J. Wimalawansa Eradication of CKDu (CKD-CTN) is straightforward and costs less than 10% of what the health department spends annually to manage CKDu!  Yet new patents and deaths are continuing.    Authorities have hardly any interest in preventing CKDu, partly due to those affected having little voice and thus being ignored by politicians.  Besides, there […]

by Professor Sunil J.  Wimalawansa Types of leadership Sri Lanka needs?

by Professor Sunil J.  Wimalawansa Consequences of IMF loans: Under IMF-imposed policies, Sri Lanka has witnessed the dramatic deterioration of many local industries.  Sri Lanka had sold off its profitable public sector enterprises such as the Tire Corporation, Sugar Corporation, Milk-food Corporation, Air Lanka (which used to be Sri Lanka’s national airline), Ceylon Transport Board, […]

by Professor Sunil J.  Wimalawansa Would taking excessive (unnecessary) loans by Sri Lanka lead to bankruptcy? In 2002, Sri Lanka paid more than US $320 million as import duties to affluent countries.  While some European countries exported three to five times more than Sri Lanka, Norway paid only $125 million, and Switzerland paid $245 million […]

by Professor Sunil J.  Wimalawansa Pre-requisites for economic development and the need for a new constitution The stagnation of the Sri Lankan economy since gaining independence from the British is striking.  This is due to selfish politicians lacking: a vision for the country, forward-looking policies, and long-term national development plans (e.g., for clean water).  The […]

by Professor Sunil J.  Wimalawansa Properly trained labour force with skills, ethics, and attracting FDIC The skilled labour force in Sri Lanka is either stagnant or decreasing with exiting to other countries.  Most could speak and/or understand English, and fewer speak other foreign languages.  Hence, besides vastly expanding skills training centres—universities as described above, the […]

Professor Sunil J. Wimalawansa Over-confidence and reliance on out of date information, lack of familiarity with recent rapidly changing medical and scientific advances, and ‘close-mind set’ is likely to lead to inadvertently making false comments and unfair criticisms.  There are over 350 published, recent peer-reviewed clinical scientific papers on being significant benefits of vitamin D and […]

Dr. Sunil J.

Sunil Wimalawansa The macroeconomic issues (e.g., trade) are poorly handed by many south Asian countries, including successive governments in Sri Lankan.  This seems to be getting worse in recent years, leading to increasing weakening of local currency and increasing debt.  The latter further increases the cost of borrowing and loan payments to creditors, and credit […]
