  • People who are middle-aged and older are more likely to suffer from this type of diabetes. It was once known as adult-onset diabetes. However, type 2 diabetes is a problem for teens and children, most often due to weight gain during childhood.
  • Type 2 diabetes is by far the most well-known kind of diabetes. Around 29 million people are living in the U.S. with type 2. The remaining 84 million suffer from prediabetes. This means that your blood sugar level (or the blood sugar) is elevated but not enough to cause diabetes.

Signs and Symptoms of Type 2 Diabetes

The signs of type 2 diabetes may be so minor that it’s hard to notice. The majority of people with the disease do not know about it. Its symptoms include:

  • Being extremely thirsty
  • Peeing a lot
  • Blurry vision

If you’ve noticed black rashes that appear around the armpits or neck area, consult your physician. They are known as acanthosis nigricans and indicate your body getting intolerant to insulin.

Causes of Type 2 Diabetes

The pancreas is the organ that produces an insulin-like hormone. It assists your cells to convert glucose, a kind of sugar derived from foods you consume, into energy. People who have type 2 diabetes produce insulin, but their cells do not make it as efficiently as they ought to.

In the beginning, your pancreas releases more insulin to introduce sugar into cells. But, over time, it’s unable to keep up, and glucose accumulates in the bloodstream instead.

Most often, a combination of factors can cause Type 2 Diabetes. It could be:

  • Genes. Scientists have identified different pieces of DNA that influence how your body makes insulin.
  • Additional weight. Being obese or overweight can result in insulin resistance, mainly if you carry extra weight in your middle.
  • “Metabolic Syndrome. Patients with insulin resistance frequently suffer from several conditions such as high blood sugar and excess fat around the waist and hips, high blood pressure, high cholesterol, and triglycerides.
  • Excessive glucose in your liver. If your blood sugar is lower, the liver produces and releases glucose. When you eat the food, your blood sugar will go up, and your liver tends to reduce its activity and store the glucose to use later. However, some livers aren’t. They keep pumping out sugar.
  • Bad communication between cells. Sometimes, cells transmit incorrect signals or do not recognize messages correctly. If these problems impact how your cells produce and utilize glucose or insulin, the chain reaction could cause diabetes.
  • Broken beta cells. If the cells responsible for making insulin release an insufficient quantity of insulin at the right moment, the blood sugar level gets out of balance. A high blood sugar could damage these cells too.
