What is Diabetes?

Diabetes mellitus (Diabetes) is a chronic metabolic disorder caused by high blood sugar levels. Sugar taken with food passes into the stomach, from there to the intestines, and is absorbed into the blood. Insulin is absolutely necessary for sugar to enter the cell. Insulin acts as the key that opens the cell’s door for sugar to enter the cell. When the pancreas cannot produce enough insulin or insulin cannot perform its key function (insulin resistance), sugar cannot enter the cell and turn into energy. Therefore, sugar begins to rise in the blood.

Diabetes mellitus caused by insulin deficiency is Type 1 Diabetes and cannot be treated with surgery. Today, the most effective treatment method for this disease is to use insulin. When insulin production in the pancreas decreases or insulin production is sufficient, it cannot show sufficient effect at the level of tissues and organs, that is, with insulin resistance, ‘type 2 diabetes’ develops and the most effective treatment method is ‘diabetes surgery (gastric bypass). 90% of diabetics have type 2 diabetes. Type 1 diabetes occurs as a result of the development of antibodies against the insulin-secreting beta cells in the pancreas and usually begins to appear in childhood. Type 2 diabetes is mostly seen after the age of 25 due to insulin resistance. More than half of type 2 diabetes patients are also obese.

What is Diabetes Surgery (Type 2 Diabetes Surgery)?

Some mistakes in eating habits, obesity and sedentary life cause a decrease in insulin secretion from the pancreas or the development of resistance to insulin in the cell, which in turn causes Type 2 Diabetes (Diabetes) due to an increase in blood sugar.
50% of diabetic patients also have obesity problem. In other words, there are 4 million four hundred thousand both obese and diabetic patients in Turkey. In people with these diseases, we call co-morbidities; sleep problems, high blood pressure, heart diseases, knee pain, high blood values, fatty liver, sexual and hormonal problems, some types of cancer are common. After diabetes surgery, patients get effective and permanent results by getting rid of insulin and diabetes medications. If other patients who cannot stop the drug also use insulin, they switch to a lower dose or blood sugar control is provided with oral anti-diabetic drugs.

Which Type of Surgery Can Be Performed for Diabetics?

Today, the most frequently applied and most effective surgeries are Omega Loop Gastric BY Pass, Roux-en-Y Gastric By Pass, Biliopancreatic diversion and Jejunoileal by Pass methods. The success rates of these surgical methods are close to each other. Surgeons apply the method that they think will get the best result with the least risk from these methods. Associate Professor. İbrahim Sakçak revised the Omega Loop Gastric Bypass method and made it more perfect and applies this method to all his patients.

Can Every Diabetic Patient Be Healed With Surgery?

Currently, there is no treatment method that provides acceptable success and completely eliminates the disease in type 1 diabetes patients with congenital absence of insulin.
