Tonga is a country located in the Pacific Ocean. It is made up of about 171 islands and atolls. The nation has more than 100,000 people, most of whom live on the main island, Tongatapu. The country is known for its pristine beaches and whale-watching hub. However, Tonga is dealing with many diseases that are impacting the lives of its citizens.

Main Health Issues

The main health concerns impacting Tonga are noncommunicable diseases (NCDs), such as obesity and diabetes. Tonga has the second-highest obesity rate in the world, with more than 70% of Tongans obese. Additionally, an estimated 40% of Tonga’s population has type 2 diabetes, while 30–40% are affected by NCDs.

The leading cause of NCDs in Tonga is poor diet. Tonga is a developing country and according to the Asian Development Bank, 20% of its population lives below the poverty line. Most people cannot afford healthier food options, relying on cheap imported fat, sodium and sugar foods. Mutton flaps, in particular, are a common and affordable staple despite their extremely high-fat content. Over time, they’ve become a prominent part of Tongan cuisine, with many people developing a lifelong taste for them from childhood.

Smoking is another major contributor to the high rates of NCDs in Tonga. Tobacco use is widespread, with an estimated 30% of adults smoking and 19.5% of youths aged 10–14 also using tobacco. Cigarette use significantly increases the risk of NCDs such as cancer, heart disease and diabetes.

Among communicable diseases, Tonga experienced a measles outbreak in 2019, with more than 500 confirmed cases but no reported deaths. The outbreak affected several Pacific island nations, including neighboring countries like Fiji and Samoa. In Tonga, the outbreak began after rugby players returned from New Zealand.

Solutions

The Tongan government has taken steps to combat the NCD epidemic in the country. It has increased taxes on unhealthy foods such as mutton flaps, turkey tails, corned beef and sugary drinks. The government also plans to make healthier options (such as fish) more available.

Nongovernmental organizations (NGOs), including the Pacific Community (SPC) and World Health Organization (WHO), are also active in Tonga. They support awareness campaigns, school-based health programs and community screenings for hypertension and diabetes.

The Tonga Health Promotion Foundation, a local NGO, collaborates with government and international agencies to promote physical activity and reduce tobacco and alcohol use. These combined efforts aim to shift dietary habits and reduce risk factors contributing to NCDs in Tonga.

Conclusion

Tonga faces a severe health crisis driven by poverty, poor diets and widespread tobacco use. NCDs like obesity and diabetes are rampant, affecting a large portion of the population. While government policies and taxes on unhealthy foods help, long-term change depends on partnerships with NGOs like WHO and SPC. These efforts aim to improve public health and secure a healthier future for Tongans through education and prevention programs.
