What is Diabetes?

Causes of Diabetes

The causes of diabetes can vary depending on the kind of diabetes that has affected you. Here are some of the primary causes of diabetes:

Type 1 diabetes

Autoimmune factors: In type 1 diabetes, the immune system mistakenly attacks and destroys the insulin-producing cells (beta cells) in the pancreas. The cause of this autoimmune response is not fully understood, but genetic and environmental factors are believed to play a role.

Type 2 diabetes

• Insulin resistance: It is a condition where the body’s cells become less responsive to insulin. This leads to high blood sugar levels. The exact mechanism behind insulin resistance is not fully understood, but it is influenced by genetic and lifestyle factors.
• Genetic factors: Family history and genetics can increase the risk of developing type 2 diabetes. Certain gene variants can affect insulin production , insulin sensitivity, and other factors involved in glucose metabolism.

Gestational diabetes

• Hormonal changes: The changes in your hormones can interfere with insulin, leading to gestational diabetes.
• Insulin production: Some women may not produce enough insulin to meet the increased insulin demands during pregnancy, leading to gestational diabetes.

Other causes

• Being obese or overweight
• Lack of physical activity
• Consuming a diet rich in processed foods, sugary drinks, unhealthy fats, and low in fibre
• Some ethnic groups such as African-Americans, Hispanics, Native Americans, and Asians.

Key Facts About Diabetes

Major Symptoms	Excessive thirst Increased urination Lethargy Blurred vision Elevated hunger Sore or wounds that take longer to heal Numbness in feet or hands Sudden weight loss
Necessary Health Tests	Fasting plasma glucose test A1C test Random plasma glucose test Glucose challenge test Oral glucose tolerance test
Treatment	Insulin therapy Monitoring blood sugar levels Oral medication Regular physical activity Eating a healthy diet Monitoring carbohydrate intake

Symptoms of Diabetes

Since the body is unable to regulate glucose levels if someone develops diabetes, it is vital to take note of its symptoms. Here are some of the common symptoms of diabetes you should know:

• Increased hunger
• Dehydration
• Frequent urination
• Yeast infection
• Slow healing
• Sudden weight loss
• Mood swings
• Blurry vision
• Lethargy
• Dry and itchy skin

Diagnosis of Diabetes

Diabetes is typically diagnosed with blood tests and clinical evaluations. While the diagnosis may be different at different medical centres, some common diagnostic techniques include:

1. Fasting plasma glucose (FPG) test

This test measures the blood sugar level after an overnight fast of at least 8 hours. A blood sample is taken, and if the fasting plasma glucose level is equal to or higher than 126 milligrams per deciliter (mg/dL) on two separate occasions, it means that you have diabetes.

2. Oral glucose tolerance test (OGTT)

For this test, the individual fasts overnight and then drinks a glucose-rich beverage. The doctor may take blood samples before the drink and at regular intervals to check the body’s response to glucose. If the blood sugar level is equal to or exceeds 200 mg/dL after 2 hours, it indicates diabetes.

3. Haemoglobin A1c (HbA1c) test

This is another test that measures the percentage of haemoglobin in the blood that is glycated (bound to glucose). An HbA1c level equal to or greater than 6.5 percent is indicative of diabetes.

4. Random plasma glucose test

For this test, the doctor takes a blood sample during any time of the day, regardless of when the person last ate. If the random plasma glucose level is equal to or exceeds 200 mg/dL and the individual exhibits classic symptoms of diabetes.

You may have to undergo different diagnostic tests or protocols as guided by your healthcare professional. If you have any symptoms of diabetes, consult your doctor and they will recommend the necessary treatment you require.

Treatment of Diabetes

1. Oral medication

Medication is prescribed depending on the type of diabetes and individual needs. These medications help bring down blood sugar levels.

2. Insulin therapy

Individuals with type 1 diabetes and some with type 2 diabetes may require insulin injections to regulate blood sugar levels effectively.

3. Blood sugar monitoring

If you have diabetes, it becomes vital to self-monitor blood sugar levels regularly using a glucometer. It helps individuals with diabetes to understand their glucose levels and take appropriate measures to keep them in control.

4. Regular check ups

Not just self-monitoring, it is also recommended to pay regular visits to healthcare professionals for diabetes management. Monitoring blood sugar levels, assessing overall health, managing medication and addressing complications can help manage your blood glucose levels.

5. Healthy eating

It is vital to eat a well-balanced diet that includes appropriate carbohydrate intake, portion control, and regular meal timing can help manage blood sugar levels.

6. Regular exercise

You should engage in regular physical activity to improve insulin sensitivity, manage weight and control blood sugar levels. It is essential to choose activities suitable for you and do them under the guidance of a professional.
