Diabetes is a serious global health threat. Health experts are concerned about the rate at which this disease is affecting people worldwide. The Indian population is at an even greater risk. The rising rate of diabetes in India has led to India being called the "Diabetes Capital of the World."
Diabetes is a metabolic disorder in which the body either fails to produce enough insulin or utilizes insulin properly, leading to elevated blood glucose levels. This hormone acts as a key to allowing glucose from food to enter cells and generate energy.

Studies show that diabetes gradually weakens the body, causing permanent damage to many vital organs over time. While diabetes is widely discussed as a cause of heart problems, weakened eyes, and kidney disease, did you know that it can weaken both your brain and hands?
Problems in the body caused by diabetes
In a recent report published in Amar Ujala, we explained how this disease is increasing the risk of deafness in people. According to a report by the Hearing Health Foundation, high blood sugar levels weaken the small nerves in the ears, just like in the eyes, and can affect your hearing. Diabetes can also affect many other organs in the body.
Long-term high blood sugar damages blood vessels and nerves. This increases the risk of heart disease by 2-4 times.
Diabetic nephropathy can also lead to kidney failure.
Damage to the small blood vessels in the eyes causes diabetic retinopathy, which can even lead to blindness.
Nerve damage increases the risk of numbness, pain, and infection in the feet, a condition known as diabetic neuropathy.
Diabetes patients are also at risk for dementia.
A team of experts studying how diabetes affects the body has found that people with diabetes may be at higher risk for dementia than others.
Dementia is a neurodegenerative condition that damages brain cells, affecting memory, thinking, behavior, and daily functioning. People with Alzheimer's disease are at higher risk for dementia.
Researchers have found that people with type 2 diabetes who have diabetic retinopathy may have a higher risk of Alzheimer's disease and dementia than those without diabetes.
Having diabetes, with or without retinopathy, also increases the risk of dementia.

What impact does diabetes have on the brain?
A team of health experts found that in people with diabetes, diabetic retinopathy has been shown to cause dementia.
Researchers studied data from approximately 770,000 people aged 5 years or older who visited hospitals for retinopathy screening and treatment between 2010 and January 2020.
They found that those with severe retinopathy had a higher risk of developing dementia over time.
It causes systemic microvascular damage between the retina and the brain, which also has a direct impact on the brain.
