Type 2 Diabetes - Causes, Prevention & Treatment

Type 2 Diabetes is a chronic and lifelong condition that is characterized by the inability of the cells in your body to respond adequately to insulin; the hormone that brings glucose from the blood to the cells where it is used for energy. Due to the inability of the cells to utilize the sugar in the insulin, blood sugar levels rise and the body is forced to rely on alternative energy sources in muscles and internal organs, and other parts of your body.

How is Type 2 Diabetes Caused?

  • The Pancreas is responsible for the production of a hormone called insulin that plays a crucial role in the conversion of glucose into energy.
  • Glucose is a type of sugar that is obtained from the food consumed and when the cells are not able to properly harness this energy from the insulin, blood sugar builds up leading to a variety of problems.
  • Scientists have offered several explanations for why this happens and a genetic factor might be present in some cases.
  • The Primary Causes of Type 2 Diabetes include the body’s development of insulin resistance where the cells do not respond properly to the hormone or the body’s inability to produce enough insulin to break down blood sugar.

How is Type 2 Diabetes Diagnosed?

There are several diagnostic tests with the help of the symptoms, if any, can help in the detection of Type 2 Diabetes.

  1. Glycated Hemoglobin (A1C) Test : Type 2 Diabetes diagnosis is usually done with the help of this blood test that indicates a person’s average blood sugar levels calculated for a period of around two or three months.
  2. Random Blood Sugar Test : Regular checkups to measure sugar levels in the blood can also help diagnose Type 2 Diabetes if the results are abnormally high and especially when there are accompanying symptoms.
  3. Fasting Blood Sugar Test : In this sugar test, blood sample is taken after the individual fasts for at least eight hours overnight to negate the influence of recent meals and food intake. Two tests usually needed to diagnose Type 2 Diabetes.
  4. Oral Glucose Tolerance Test (OGTT) : A liquid is administered to the individual and blood sugar levels are monitored over the next few hours. It is not very common except in the cases of pregnant women.

This is important since the two illnesses often call for distinct forms of treatment. Your primary care physician will recheck your A1C readings at least twice a year, and more often if there are any adjustments to your diabetes treatment plan. Goals for your A1C level might vary widely based on a number of variables, including your age. It is advised to have an A1C score of less than 7% for the vast majority of patients. You will also be given routine diagnostic tests for diabetes in order to check for complications of diabetes as well as any other disorders that may coexist with diabetes. Based on this, your type 1 or type 2 diabetes treatment can be worked out. Also know about best medicine for diabetes.

Type 2 Diabetes Treatment

Diabetes mellitus treatment is often a mix of both lifestyle changes as well as medication. It is best to consult an Endocrinologist to ascertain the best course of treatment. The main cause of type 2 diabetes is insulin resistance, which is something that can be treated and put into remission. Apart from taking medication, treatment for type 2 diabetes includes:

  • Losing a significant amount of weight and maintaining a healthy BMI. The less fat there is in the body the better it is for people with type 2 diabetes as it maintains their blood sugar levels. 
  • Eating a diabetes friendly healthy diet comprising leafy greens, protein, healthy fats and very less carbs. Eating a balanced and healthy diet, while controlling portion sizes is crucial as this will not result in any blood sugar spikes after meals.
  • Following a regular exercising routine. Exercising uses up the glucose in the blood as energy which ultimately balances blood sugar levels and prevents an accumulation of glucose in the bloodstream causing hyperglycemia. 
  • Keeping tabs on your blood sugar levels and regularly visiting your doctor. It is important to regularly check your blood sugar levels as it has various benefits; it gives an accurate picture of your condition and assists your doctor in determining which medication to prescribe. 

When lifestyle changes do not achieve the desired results, medication is a must. Metformin is usually considered the best medicine for Type 2 Diabetes which helps the body respond better to insulin. Other medications also include Meglitinides that boost insulin production, insulin shots, and also DPP-4 inhibitors that directly lower blood sugar levels. Also know about endocrinology doctor. Here are some of the most commonly used medicines for type 2 diabetes.

  • Metformin: This long-used medication decreases the amount of glucose the body produces. It is among the best tolerated and most thoroughly researched diabetic medications.
  • Sulfonylureas: These medications promote the body's production of insulin. They have also been in use for a time, much like metformin. Sulfonylureas are somewhat more likely to cause hypoglycemic episodes than metformin.
  • Glitazones: The only glitazone still available is pioglitazone. Pioglitazone is less likely to result in hypoglycemia than sulfonylureas.
  • Nateglinide and repaglinide: are examples of glinides. They boost the body's capacity to produce insulin.
  • Insulin production: is also stimulated by gliptins (dipeptidyl peptidase-4 inhibitors). They consist of the medications vildagliptin, sitagliptin, saxagliptin, and linagliptin.
  • Dapagliflozin, empagliflozin, and canagliflozin: are examples of gliflozins (SGLT2 inhibitors). They reduce blood sugar levels by increasing the amount of sugar expelled in urine. Also read about sugar level in urine

You should monitor your blood sugar level after each meal. Investigate how the foods and beverages you consume alter the quantity of sugar in your blood after you have completed eating and drinking. You should also strive to maintain consistency in the quantity of grams or servings of carbs you consume with each meal, and keep note of this information. This may also help you have a better understanding of your blood sugar levels.

While eating the right foods helps, avoiding certain food groups is just as important. Here are the foods that people with diabetes should avoid:

  • Saturated fat-free foods include: meals rich in saturated fat may raise cholesterol levels in the blood. It can be found in high-fat dairy goods and coconut oil, as well as high-fat animal proteins like bacon and sausage, as well as high-fat dairy products like butter, full-fat cheese, and ice cream, as well as chicken skin and coconut oil.
  • Trans fats are liquid oils at room temperature that solidify when heated. They are also known as partly hydrogenated or hydrogenated oil. Trans fats are included in processed meals such as certain kinds of fast food chips, cookies, and French fries.
  • The cholesterol in your body is a mix of cholesterol generated naturally in the liver and cholesterol absorbed via meals. Keep an eye out for high-fat dairy and animal products, as well as high-fat egg yolks, liver, and other organ meats.
  • Don't forget the importance of keeping track of how much salt you consume. This is one major part of a diabetes-friendly diet. It has been demonstrated that lowering one's salt intake may aid in the treatment and prevention of high blood pressure. Learn to read food labels and choose foods with reduced salt levels.

Complications Of Type 2 Diabetes

Diabetes complications often share risk factors, and one illness might speed the advancement of another. Here are some complications that generally occur with type 2 diabetes:

  • Many people with diabetes have high blood pressure, which may exacerbate ocular and renal disorders. 
  • Triglycerides are a kind of blood fat, and diabetes raises LDL cholesterol, the "bad" cholesterol, while decreasing HDL cholesterol, the "good" cholesterol. Because of these changes, the risk of cardiovascular disease and stroke may rise. 
  • For people with diabetes, tobacco smoking is connected with an increased risk of cardiovascular disease and is strictly prohibited for type 2 diabetes treatment to work.

There is a lot of information that goes into establishing whether or not a person will have specific health issues. A person's genetic make-up, the type of diabetes they have, the medicines they are on, their mental state and well-being, as well as their lifestyle choices both before and after being diagnosed with diabetes, are all major factors to the development of these illnesses. If you see anything out of the ordinary, schedule an appointment with your doctor as soon as possible.
