Quick Diabetes Overview

Diabetes is when your blood sugar levels are too high because your body has trouble using a hormone called insulin. There are three main types: Type 1, Type 2, and gestational diabetes. Type 1 happens mostly in kids when their immune system attacks insulin-making cells. People with Type 1 need insulin shots. Type 2, more common in adults, is when your body does not use insulin well or doesn’t make enough. Lifestyle changes, pills, or insulin can help manage it. Gestational diabetes occurs during pregnancy. Common signs include always feeling thirsty, hungry, peeing a lot, feeling tired, losing weight without trying, and blurry vision. If not managed, diabetes can lead to heart issues, kidney problems, nerve damage, and eye troubles. Managing diabetes means taking medicine, making healthy lifestyle changes, and checking blood sugar levels often. It is important to talk with doctors for the best care.

What Is Type 2 Diabetes?

Type 2 diabetes happens because the body has trouble using sugar properly. Sugar, also called glucose, is like fuel for our bodies. In this condition, there’s too much sugar in the blood for a long time. This can cause problems with the circulatory, nervous, and immune systems. In type 2 diabetes, two main things go wrong. First, the pancreas doesn’t make enough insulin, which is a special hormone that helps sugar get into our cells. Second, the cells don’t respond well to insulin, so they don’t take in enough sugar.

People used to call it adult-onset diabetes, but now both kids and adults can get it. It is more common in older adults, but more kids are getting it because of too much weight. Even though there’s no cure, you can manage type 2 diabetes by losing weight, eating healthy, and exercising. If that’s not enough, doctors might suggest medicines or insulin to help control blood sugar levels. Unfortunately, there is no cure for type 2 diabetes. However, lifestyle changes like losing weight, eating well, and exercising can help manage the condition. If these measures aren’t enough to control blood sugar levels, healthcare providers may recommend diabetes medications or insulin therapy. Regular check-ups and working closely with healthcare professionals are important for effective management.

Type 2 Diabetes Symptoms

Type 2 diabetes symptoms can vary, and some people may not experience noticeable signs in the early stages. However, common symptoms include:

  1. Increased Thirst and Hunger: Feeling extremely thirsty and hungry, even after eating.
  2. Frequent Urination: Needing to urinate more often than usual, especially at night.
  3. Fatigue: Feeling unusually tired or lacking in energy.
  4. Unexplained Weight Loss: Losing weight without trying, even if you’re eating more than usual.
  5. Blurred Vision: Experiencing blurry vision or seeing changes in your eyesight.
  6. Slow Healing of Wounds: Cuts and sores taking longer to heal than usual.
  7. Tingling or Numbness: Feeling tingling or numbness in the hands or feet.

Some people with type 2 diabetes may not experience noticeable symptoms, or the symptoms may develop gradually. Regular check-ups and blood sugar monitoring are huge important, especially for those at risk or with a family history of diabetes. If you notice any of these symptoms, it is essential to consult with a doctor for proper evaluation and diagnosis. Early detection and management of type 2 diabetes are key to preventing complications.

What Causes Type 2 Diabetes?

Insulin resistance, a condition where cells in the body become less responsive to insulin, plays a key role in the development of this health condition. This hormone is very important for regulating blood sugar levels, and when the body is resistant to its effects, it becomes challenging for glucose to enter cells. Additionally, the pancreas, responsible for insulin production, may not generate enough to overcome this resistance. The exact cause of this condition involves a mix of genetic and lifestyle factors.

Genetics also contribute; a family history of diabetes can increase the risk, and specific genes may predispose individuals to insulin resistance. Excess body weight, particularly around the abdomen, is a significant risk factor, closely linked to insulin resistance. Lack of regular physical activity is associated with an increased risk, as exercise helps improve insulin sensitivity and contributes to weight management.

An unhealthy diet, high in processed foods, sugary beverages, and unhealthy fats, can lead to weight gain and insulin resistance. The risk increases with age, especially after 45, and is now found in younger people due to rising obesity rates. Certain ethnic groups, such as African Americans, Hispanic Americans, Native Americans, and Asian Americans, face a higher risk.

Women who had gestational diabetes during pregnancy are at an increased risk later in life. These factors contribute to its development, but it’s essential to note that the condition is preventable and manageable through lifestyle changes, including maintaining a healthy weight, regular exercise, and a balanced diet. Early detection and intervention are important in preventing complications associated with this health condition.

How Insulin Manages Sugar in Body?

Insulin, an important hormone produced by the pancreas, plays a key role in regulating sugar in your body. Let’s break down the process in simple terms:

  1. Sugar Trigger and Release: When there is sugar in your bloodstream, your pancreas responds by releasing insulin.
  2. Sugar’s Journey into Cells: Insulin travels in your bloodstream, helping sugar enter your cells, where it becomes a crucial source of energy.
  3. Blood Sugar Regulation: As sugar enters cells, the overall sugar level in your bloodstream decreases.
  4. Feedback Loop: When the sugar level drops, the pancreas releases less insulin, maintaining a delicate balance.

The Significance of Glucose:

Glucose, a type of sugar, serves as a primary energy source for your muscles and tissues. Here is how it works:

  1. Sources of Glucose: Your body gets glucose from two main sources — the food you eat and the liver, which stores and produces glucose.
  2. Insulin’s Assistance: With the help of insulin, glucose is absorbed into the bloodstream and then enters cells.
  3. Liver’s Role: The liver is responsible for storing and creating glucose. When glucose levels are low, the liver breaks down stored glycogen into glucose to ensure your body maintains a healthy glucose level.

Type 2 Diabetes Risk Factors:

Type 2 diabetes is a complex condition influenced by a combination of genetic, lifestyle, and environmental factors. Here are some common risk factors associated with the development of type 2 diabetes:

  1. Age: The risk of developing this condition increases with age, particularly after the age of 45.
  2. Family History: If a parent or sibling has the condition, the risk is higher due to genetic factors.
  3. Ethnicity: Certain ethnic groups, including African Americans, Hispanic/Latino Americans, Native Americans, Asian Americans, and Pacific Islanders, have a higher risk.
  4. Obesity: Excess body weight, especially around the abdomen, is a significant risk factor. It is closely linked to insulin resistance.
  5. Physical Inactivity: Lack of regular physical activity is associated with an increased risk. Exercise helps control weight and improves insulin sensitivity.
  6. Unhealthy Diet: A diet high in refined carbohydrates, sugary beverages, saturated and trans fats, and low in fiber can contribute to the risk.
  7. Gestational History: If a woman develops gestational diabetes during pregnancy, her risk increases.
  8. Polycystic Ovary Syndrome (PCOS): Women with PCOS have a higher risk.
  9. Hypertension (High Blood Pressure): Having high blood pressure is a risk factor.
  10. High Cholesterol Levels: Abnormal levels of LDL cholesterol and low levels of HDL cholesterol may increase the risk.
  11. Sleep Apnea: Untreated sleep apnea can increase the risk of developing insulin resistance.
  12. Smoking: Smoking is associated with an increased risk. Smokers may also find it more challenging to manage the condition if they develop it.


Type 2 diabetes affects many major organs, including the heart, blood vessels, nerves, eyes and kidneys. Also, factors that increase the risk of diabetes are risk factors for other serious diseases. Managing diabetes and controlling blood sugar can lower the risk for these complications and other medical conditions, including:

  1. Cardiovascular Complications: People with this condition are at an increased risk of cardiovascular diseases, including heart disease and stroke.
  2. Nerve Damage (Neuropathy): Prolonged high blood sugar levels can lead to nerve damage, causing symptoms such as tingling, numbness, and pain, usually in the hands and feet.
  3. Kidney Damage (Nephropathy): Diabetes can affect the kidneys, leading to kidney disease or even kidney failure over time.
  4. Eye Complications: Diabetes can cause damage to the blood vessels in the eyes, leading to conditions such as diabetic retinopathy, which can result in vision problems and blindness if not managed.
  5. Foot Complications: Nerve damage and poor circulation can lead to foot problems, including infections and ulcers. In severe cases, this may require amputation.
  6. Skin Complications: Diabetes can affect the skin, causing conditions such as bacterial and fungal infections, particularly if blood sugar levels are poorly controlled.
  7. Hearing Impairment: People with diabetes may have a higher risk of hearing loss.
  8. Alzheimer’s Disease: Some studies suggest a link between diabetes and an increased risk of developing Alzheimer’s disease or other forms of dementia.
  9. Mental Health Issues: Living with a chronic condition can contribute to mental health challenges such as depression and anxiety.
  10. Gastrointestinal Issues: Diabetes can affect the digestive system, leading to problems like gastroparesis, a condition where the stomach takes longer to empty.
  11. Sleep Apnea: There is an increased risk of sleep apnea in people with diabetes, which can further contribute to cardiovascular issues.

Type 2 Diabetes Treatment

Type 2 diabetes is a chronic condition that affects the way the body processes blood sugar (glucose). It is characterized by insulin resistance, where the body’s cells do not respond effectively to insulin, and insufficient insulin production over time. Managing type 2 diabetes involves a combination of lifestyle changes, medication, and, in some cases, insulin therapy. It’s important to note that the treatment plan may vary for each individual, and it’s essential to work closely with healthcare professionals to develop a personalized approach. Here are some common aspects of type 2 diabetes treatment:

  1. Lifestyle Modifications:
    • Healthy Eating: Adopting a balanced and nutritious diet is crucial. Focus on whole grains, fruits, vegetables, lean proteins, and healthy fats. Limit the intake of processed foods, sugary beverages, and high-fat items.
    • Regular Exercise: Physical activity helps improve insulin sensitivity and blood sugar control. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, along with strength training exercises at least twice a week.
  2. Medications:
    • Oral Medications: There are various classes of oral medications that can help lower blood sugar levels. These include metformin, sulfonylureas, meglitinides, DPP-4 inhibitors, SGLT2 inhibitors, and others. The choice of medication depends on factors such as the individual’s overall health, the severity of diabetes, and other considerations.
  3. Insulin Therapy:
    • In some cases, insulin therapy may be prescribed to help regulate blood sugar levels. This can be short-acting or long-acting insulin, and the regimen may vary based on the individual’s needs.
  4. Monitoring Blood Sugar Levels:
    • Regular monitoring of blood glucose levels is essential to track the effectiveness of the treatment plan. This may involve daily blood glucose testing using a glucose meter.
  5. Weight Management:
    • Losing excess weight and maintaining a healthy weight can significantly improve insulin sensitivity and blood sugar control.
  6. Regular Medical Check-ups:
    • Regular follow-up with healthcare providers is crucial to monitor the progression of diabetes, adjust treatment plans as needed, and address any complications or concerns.
  7. Education and Support:
    • Education about diabetes management and lifestyle changes is essential. Diabetes education programs and support groups can provide valuable information and emotional support.

Medication For Diabetes Type 2

There are several classes of medications used to treat type 2 diabetes, and the choice of medication depends on various factors such as the individual’s overall health, the severity of diabetes, and other considerations. Here are some common types of medications used for the management of type 2 diabetes:

  1. Metformin:
    • Metformin is usually the first-line medication for type 2 diabetes. It helps lower blood sugar by reducing the amount of glucose produced by the liver and improving insulin sensitivity in the body’s tissues.
  2. Sulfonylureas:
    • Medications in this class stimulate the pancreas to release more insulin. Examples include glyburide, glipizide, and glimepiride.
  3. Meglitinides:
    • Meglitinides also stimulate insulin release from the pancreas but have a shorter duration of action than sulfonylureas. Examples include repaglinide and nateglinide.
  4. DPP-4 Inhibitors (Dipeptidyl Peptidase-4 Inhibitors):
    • These medications increase insulin release and reduce glucose production. Examples include sitagliptin, saxagliptin, linagliptin, and alogliptin.
  5. SGLT2 Inhibitors (Sodium-Glucose Cotransporter-2 Inhibitors):
    • SGLT2 inhibitors work by preventing the kidneys from reabsorbing glucose, leading to increased glucose excretion in the urine. Examples include canagliflozin, dapagliflozin, and empagliflozin.
  6. GLP-1 Receptor Agonists (Glucagon-Like Peptide-1 Receptor Agonists):
    • GLP-1 receptor agonists increase insulin release and reduce glucagon secretion. They also slow down gastric emptying and promote a feeling of fullness. Examples include exenatide, liraglutide, dulaglutide, and semaglutide.
  7. Thiazolidinediones (TZDs):
    • TZDs improve insulin sensitivity in the body’s tissues. Examples include pioglitazone and rosiglitazone.
  8. Alpha-glucosidase Inhibitors:
    • Medications in this class slow down the digestion of carbohydrates, leading to a slower rise in blood sugar levels. Examples include acarbose and miglitol.
  9. Insulin:
    • Insulin therapy may be prescribed when oral medications are not sufficient to control blood sugar levels. Insulin can be short-acting, intermediate-acting, or long-acting, and the regimen may vary based on the individual’s needs.

The combination of medications is determined by factors such as the individual’s overall health, the presence of other medical conditions, the risk of hypoglycemia (low blood sugar), and patient preferences.

Living With Type 2 Diabetes

Living with type 2 diabetes requires a combination of lifestyle changes, medication management, and regular monitoring to maintain blood sugar levels within a healthy range. Here are some key aspects to consider:

    • Discuss any concerns or challenges you may be facing with your healthcare team.
  6. Weight Management:
    • Maintaining a healthy weight is crucial for managing type 2 diabetes. If overweight, even a modest weight loss can improve insulin sensitivity and blood sugar control.
  7. Stress Management:
    • Practice stress-reducing techniques such as meditation, deep breathing exercises, or yoga.
    • Chronic stress can affect blood sugar levels, so finding healthy ways to cope is important.
  8. Educate Yourself:
    • Learn about diabetes, its management, and how it specifically affects you.
    • Stay informed about new developments in diabetes care.
  9. Foot Care:
    • People with diabetes should pay extra attention to foot care. Check your feet regularly for any signs of infection or injury, and consult a healthcare professional if you notice any issues.

ICD 10 Diabetes Type 2

In the International Classification of Diseases, 10th Edition (ICD-10), the code for type 2 diabetes mellitus is E11. This code is used to classify and code diagnoses related to type 2 diabetes. It’s important to note that the ICD-10 coding system is used for medical billing, statistical tracking, and other administrative purposes in healthcare.

The complete code for type 2 diabetes mellitus includes additional characters to provide more specific information about the condition. Here’s the breakdown of the ICD-10 code for type 2 diabetes mellitus:

  • E11: Type 2 diabetes mellitus
  • E11.0: Non-insulin-dependent diabetes mellitus with hyperosmolarity
