Lifestyles, with almost zero exercise and increased consumption of junk foods, are the major reasons behind the significant surge in Type 2 diabetes cases among younger populations, both globally and particularly in India, in the last 10 years, said doctors on November 9 ahead of World Diabetes Day.

World Diabetes Day is observed every year on November 14 to raise awareness about the blood sugar condition.

India, also known as the diabetes capital of the world, has witnessed a troubling increase in Type 2 diabetes prevalence among young adults, as studies indicate a steady surge in cases among those aged 20-40.

A recent Indian Council of Medical Research-INdia DIABetes (ICMR-INDIAB) study showed that a tenth of all Indians have diabetes. The country is home to 101 million diabetics and 136 million pre-diabetic people.

The concerning trend poses substantial long-term health challenges involving other functions of the body like the cardiovascular system, kidneys, and more.

"In young individuals, potential signs of Type 2 diabetes include frequent urination, increased thirst, excessive hunger, unexplained weight loss, chronic fatigue, blurred vision, slow wound healing, and recurring infections. These symptoms may indicate elevated blood sugar levels and should prompt medical evaluation. Early detection and management are vital to prevent complications associated with diabetes,” said Dr. Mohit Sharma, Senior Consultant, Internal Medicine, Department of Endocrinology, Amrita Hospital, Faridabad.

He called for continued monitoring as many times, the symptoms tend to go unnoticed.

"The number of people suffering from diabetes is continuously increasing. Previously, we used to see diabetes only in the older population. Still, currently, we are seeing increasing cases of diabetes in the younger population," Dr. Tushar Tayal, Lead Consultant, Department of Internal Medicine, CK Birla Hospital, Gurugram, told IANS.

"The main factor for developing diabetes presently is our lifestyle. Lifestyle, if we talk about it, there's a lack of exercise, and then eating junk food and food rich in refined flour, refined sugar, and lots of trans fat," he said.

Type 2 diabetes significantly also impacts the cardiovascular system, increasing the risk of heart attacks, angina, sudden cardiac death, heart failure, strokes, and peripheral arterial disease. It can also harm an individual’s kidneys.

Younger individuals, especially women in some cases, often face a higher threat of falling prey to diabetes with a history of gestational diabetes and early puberty.

In addition, ethnic and racial minorities, lower socioeconomic backgrounds, and exposure to urban environments also make for higher susceptibility rates, the doctors said.

The health experts recommended a disciplined lifestyle to help overcome the risk factors. "Exercise for 150 minutes per week, or do 30 minutes of brisk cardio activity every day which can be cycling, jogging, running, swimming, brisk walking," Dr Tayal said.

The experts also emphasised eating a healthy diet and avoiding refined flour refined sugar and trans fat.
