Five of the 10 countries where diabetes is most prevalent are located in the six-nation Gulf Cooperation Council, according to the International Diabetes Federation (IDF), an umbrella organisation of more than 200 national associations.

Kuwait is No. 3 while Qatar is sixth, Saudi Arabia seventh, Bahrain eighth and the United Arab Emirates No. 10. The rest of the top 10 are Pacific island nations with much smaller populations, apart from Lebanon which comes in fifth.
