Especially the growing rate of type-2 diabetes among adults is a serious concern. Integrated steps must be taken to effectively manage diabetes to control its global prevalence rates.

Let’s examine the best practices that shall help in managing type-2 diabetes in 2021.

Integrated Steps of Type-2 Diabetes Management

Type 2 diabetes is more common in adults. It is therefore known as adult-onset diabetes. The global prevalence rate of type-2 diabetes is increasing. It is expected that 700 million global populations shall be affected by type-2 diabetes. It is necessary for the effective management of diseases. The key steps are:


Many myths are surrounding diabetes disease. Proper information regarding diabetes and its management shall help in preventing such myths.

It is believed that type-2 diabetes is not curable and it is a risky disease. Numerous studies report people with type-2 diabetes lack proper information and have the stress of health risks, complications, and food issues. It thus leads to anxiety and poor management of the disease. It is therefore essential that people are aware of what type-2 diabetes is and how it can be managed.

What is Type 2 Diabetes?

Type-2 diabetes is a chronic medical condition that affects the way your body metabolizes or processes blood sugar (glucose). In type-2 diabetes, glucose absorption into the cells decreases due to the cells becoming resistant to insulin. This causes glucose accumulation in the bloodstream.

Due to high glucose levels, insulin production increases. More insulin production weakens the pancreas cells. In the later stages, the body doesn’t even produce sufficient insulin.

What is type 2 diabetes


In Type-2 diabetes blood, glucose levels in the body increase when the body cells become resistant to insulin.


At first, the symptoms of type 2 diabetes are so mild that you won’t even get to notice them.

The most common symptoms are:

  • Frequent urination
  • Increased hunger
  • Increased thirst
  • Fatigue
  • Blurred vision
  • Itchy skin
  • Dry mouth
  • Weight loss

If your blood sugar is high for a prolonged period, the following clinical symptoms may become visible along with the above signs:

  • Slow-healing sores
  • Yeast infections
  • Acanthosis nigricans (dark patches on your skin)
  • Diabetes peripheral neuropathy (nerve damage)
  • Foot pain

Don’t take these warning signs casually. Consult a doctor to prevent the worsening of your condition.

Cause or Etiology of Type 2 Diabetes 

The exact cause of type- 2 diabetes is not known. But the main causes of the diseases are as follows:

  • Obesity and an inactive lifestyle serve as the most significant cause of Type 2 Diabetes Mellitus.
  • Increased glucose production by the liver: The liver converts glycogen into glucose and releases it into the bloodstream. With liver infection and disease like fatty liver, glucose production increases and causing high blood sugar levels.
  • Beta-cell dysfunction in the pancreas: The organ pancreas produces the hormone insulin- which regulates the body’s glucose. In Type 2 Diabetes, the body becomes resistant to insulin. This, in turn, forces the beta cells of the pancreas to release more insulin. Eventually, glucose starts building up in your body and leaves the cells void of energy. In the worst case, the beta cells of the pancreas become weak. Due to which they are unable to produce more insulin.
  • Genetic influence and hereditary


Type-2 diabetes causes are insulin resistance, obesity and poor lifestyle, beta-cell dysfunctioning, genetic factors, and increased production of glucose by the liver.

What are the risk factors for type 2 diabetes?

You are at higher risk of having Type 2 Diabetes if you come under any of the following factors:

  1. A family history of diabetes (A sister, brother, or parent who has type 2 diabetes)
  2. If the person is of 45 years of age, or older.
  3. Their ethnicity is African American, Alaska Native, Native American, Asian American, Hispanic or Latino, or Pacific Islander American.
  4. Women having a condition called polycystic ovarian syndrome (PCOS).
  5. if the person is already a prediabetes
  6. If they have high levels of triglycerides

However, there are some other factors which are in the person’s control. That is, If the person is –

  1. Overweight or obesity due to which the cells become more resistant to insulin.
  2. Stress and anxiety
  3. Consuming an excess of junk food or processed foods.

Diagnosis and Tests

The diagnosis of type-2 diabetes is done through various blood tests. These tests aim to measure blood sugar levels.

  • Glycated hemoglobin (A1C) test – It determines the average blood sugar level of a patient over the past two to three months. A1C test measures the amount of sugar attached to hemoglobin. Type 2 diabetes, in India, is diagnosed when the A1C is over 6.5 percent.
  • Fasting plasma glucose test – It determines the blood sugar level on an empty stomach. If the fasting blood sugar is 126 mg/dL or higher, the person is said to be diabetic.
  • Random plasma glucose test – This test is performed if you have symptoms of diabetes. It can be done at any time without considering your last meal. The random blood sugar level of 200 mg/dL or higher suggests that you have diabetes.
  • Oral glucose tolerance test (OGTT) – the test checks the blood glucose before and 2 hours after you drink a sugary liquid. If the blood sugar level is 200 mg/dL or more after 2 hours, then you have diabetes.


Blood tests measure the circulating blood glucose levels. The blood glucose levels above 130 mg/dL are abnormal.



The doctors based on the outcome of the blood tests and diagnosis may suggest any of the following medication.

  • Metformin – It lowers the production of glucose in the liver and improves the body’s sensitivity to insulin. (preferred medication)
  • Sulfonylureas – The oral medications which help your body secrete more insulin.
  • Meglitinides – It stimulates the pancreas to release more insulin. The medication is fast-acting but short-durational.
  • Thiazolidinediones – It makes the body’s tissues more sensitive to insulin. It has serious side effects and therefore, not the first-choice treatment.
  • DPP-4 inhibitors – A milder medication to reduce blood sugar levels.
  • GLP-1 receptor agonists – It slows digestion and enhances blood glucose levels.
  • SGLT2 inhibitors – The medications inhibit the reabsorption of glucose in the kidney and thereby, lower blood sugar.
  • Alpha-glucosidase inhibitors – It helps your body break down starchy foods and table sugar which lowers blood sugar.

Note: It is the doctors who shall decide on the choice and dosage of medicine. So, if you are allergic to any of the medicines or if you have skipped dose consult doctors immediately.

  • Brain – Type-2 diabetes also damages your brain and increases the risk of Alzheimer’s disease.
  • Depression – Diabetes also doubles the risk of developing depression.

Type 2 Diabetes Prevention

Some symptoms start to emerge and this makes the blood sugar levels rise. But the blood sugar levels are not so high to be diagnosed as diabetic. This is a prediabetic condition. Proper care in this condition can help you to avoid diabetes and its complication. Thus, there is a chance to prevent the conversion of prediabetes into diabetes.

To prevent the onset of type 2 diabetes:

  • Avoid a sedentary lifestyle
  • Exercise regularly and lose weight if you are obese.
  • Quit smoking
  • Follow a ketogenic or very-low-carb diet
  • Drink water and avoid beverages that are high in sugar.
