What are the causes of type 2 diabetes?
Insulin is produced by the pancreas and helps process the glucose in the blood. Thus, with inadequate insulin, the bodies can’t burn all the blood sugar for energy in an efficient way. This means the glucose level in the blood rises, causing a variety of symptoms and when severe may even lead to death.
Factors that influence the development of type 2 diabetes include:
- Genetic factors
- Increased intake of carbohydrates
- Excessive intake of calorie
- High-risk ethnic background
- Native American
- African American
- Asian American
- Lack of physical activity
- Sedentary lifestyle
- Age greater than 45 years
- Family history of diabetes
- History of diabetes during pregnancy
- Ovarian cyst diseas
What are the symptoms and signs of type 2 diabetes?
The classic symptoms of type 2 diabetes seen in the early stages are
- Increased thirst
- Increased urine frequency
- Increased appetite
- Urinating frequently at night
- Weight loss
The symptoms which occur in the later stages are
- Blurred vision
- Numb or tingling hands and feet
- Wounds that heal slowly
- Increased infections than usual
- Low blood sugar level
Most frequently, however, type 2 diabetes does not cause any symptoms for several years and may go unnoticed.
What are the complications of type 2 diabetes?
Diabetes, if poorly controlled or left untreated, can lead to severe complications, which are as follows:
- It may affect different organs of the body especially, the heart, eye, kidney, and nerves.
- It may affect the eyes causing blindness in adults.
- It is a major contributor to end-stage kidney disease in the United States.
- It can lead to leg amputation.
- There is an increased rate of post-surgery pneumonia.
- The risk of stroke is higher.
- The death rate is higher among COVID-19 patients with an underlying diabetic condition.
How is type 2 diabetes diagnosed?
The different diagnostic criteria set by the American Diabetes Association are:
What is the treatment for type 2 diabetes?
Goals of treatment are as follows:
- Preventing blindness or end-stage kidney disease, through control of blood sugar level and blood pressure
- Preventing stroke or heart disease by controlling cholesterol, blood pressure, and tobacco use.
- Preventing nerve damage by controlling blood sugar
Drugs that are used to treat diabetes are known as anti-diabetic medications. The different classes of antidiabetic drugs used are:
- Biguanides: metformin
- Sulfonylureas: glyburide, glipizide
- Meglitinide derivatives: repaglinide
- Alpha-glucosidase inhibitors: acarbose
- Glucagon-like peptide: semaglutide
- Thiazolidinediones: pioglitazone
- Dipeptidyl peptidase 4 inhibitors: sitagliptin
- Amylinomimetics: pramlintide
- Selective sodium-glucose transporter inhibitors: dapagliflozin, canagliflozin
- Bile acid sequestrants: colesevelam
- Rapid-Acting insulins
- Intermediate-acting insulins
- Long-acting insulins
- Dopamine agonists: bromocriptine
Can diabetes be cured?
Diabetes can be well-controlled by controlling the symptoms, but it cannot be completely cured as it is a chronic disease. Hence, prevention is key.
- Lead a healthy lifestyle by reducing weight.
- Ensure a balanced diet with proper nutrition.
- Avoid junk food or extremely fatty foods.
- Exercise daily for 30-40 minutes.
- Limit the intake of alcohol and refrain from smoking tobacco.
- Increasing the intake of some essential minerals such as magnesium has shown to decrease the risk of diabetes.
- Monitor the blood sugar level from time to time.
- Be conscientious about your annual eye check-ups.

Diabetes (Type 1 and Type 2)Diabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.

- and a diabetic diet.
Type 2 diabetes is first treated with:
- weight reduction,
- a diabetic diet,
- and exercise.
When these measures fail to control the elevated blood sugar, oral medications are used. If oral medications are still insufficient, insulin medications are considered.
Type 2 Diabetes Diet PlanA type 2 diabetes diet or a type 2 diabetic diet is important for blood sugar (glucose) control in people with diabetes to prevent complications of diabetes. There are a variety of type 2 diabetes diet eating plans such as the Mediterranean diet, Paleo diet, ADA Diabetes Diet, and vegetarian diets.Learn about low and high glycemic index foods, what foods to eat, and what foods to avoid if you have type 2 diabetes.
Tips for Managing Type 1 and 2 Diabetes at HomeManaging your diabetes is a full time commitment. The goal of diabetic therapy is to control blood glucose levels and prevent the complications of diabetes. Information about exercise, diet, and medication will help you manage your diabetes better. Blood glucose reagent strips, blood glucose meters, urine glucose tests, tests for urinary ketones, continuous glucose sensors, and Hemoglobin A1C testing information will enable you to mange your diabetes at home successfully.
Insulin Pump for DiabetesAn insulin pump is designed to deliver insulin directly to a patient with diabetes. They are about the size of a standard beeper. The pump is attached to under the skin (usually on the abdomen). The amount of insulin required will depend on lifestyle (exercise, sleep patterns, activity level, and diet).
Type 1 vs Type 2 Diabetes (Similarities and Differences)
Diabetes mellitus is a metabolic condition in which a person's blood sugar (glucose) levels are too high. Over 29.1 million children and adults in the US have diabetes. Of that, 8.1 million people have diabetes and don't even know it. Type 1 diabetes (insulin-dependent, juvenile) is caused by a problem with insulin production by the pancreas. Type 2 diabetes (non-insulin dependent) is caused by:
Eating a lot of foods and drinking beverages with simple carbohydrates (pizza, white breads, pastas, cereals, pastries, etc.) and simple sugars (donuts, candy, etc.)
- Consuming too many products with artificial sweeteners (We found out that they are bad for us!)
- Lack of activity
While the signs and symptoms of both types of diabetes are the same, which include:
- Increased urination
- Increased hunger
- Increased thirst
- Unexplained weight loss.
However, the treatments are different. Type 1 diabetes is insulin dependent, which means a person with this type of diabetes requires treatment with insulin. People with type 2 diabetes require medication, lifestyle changes like eating a healthy diet, and getting regular exercise.
Type 2 DiabetesType 2 diabetes is a chronic condition that may be reversible with diet and lifestyle changes. Symptoms include excessive thirst, frequent urination, weight loss, fatigue, and an unusual odor to your urine. Most people don't know they have type 2 diabetes until they have a routine blood test. Treatment options include medications, a type 2 diabetes diet, and other lifestyle changes.
