Diabetes is a chronic disease that affects how your body turns food into energy. When you eat, your body breaks down food into sugar (glucose) and releases it into your bloodstream. Your pancreas, an organ that lies behind your stomach, then releases insulin. Insulin acts like a key to let glucose into your cells to be used for energy.
Types of Diabetes:
There are two main types of diabetes:
1. Type 1 Diabetes:
- An autoimmune disease where your body attacks and destroys the insulin-producing cells in your pancreas.
- Usually diagnosed in children and young adults, but can develop at any age.
- Requires daily insulin injections or an insulin pump.
2. Type 2 Diabetes:
- Your body either doesn't produce enough insulin or doesn't use insulin properly.
- Often associated with lifestyle factors such as obesity, physical inactivity, and family history.
- Can be managed through diet, exercise, medication, or insulin therapy.
Prediabetes:
This is a condition where blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. It's a warning sign that you're at risk of developing type 2 diabetes.
Symptoms of Diabetes:
- Frequent urination
- Increased thirst
- Extreme hunger
- Unexplained weight loss
- Blurry vision
- Slow-healing sores
- Fatigue
Complications of Diabetes:
Untreated diabetes can lead to serious health complications, including:
- Heart disease
- Stroke
- Kidney disease
- Nerve damage
- Eye damage
- Amputations
- Alzheimer's disease
Managing Diabetes:
Diabetes management involves a combination of:
Healthy Eating: A balanced diet low in sugar and saturated fats can help regulate blood sugar levels.
Regular Exercise: Physical activity helps improve insulin sensitivity and lowers blood sugar.
Medication: Oral medications or insulin therapy may be necessary to control blood sugar levels.
Regular Monitoring: Regular blood sugar checks and A1C tests help track your blood sugar control.
Type 1 Diabetes
What is Type 1 Diabetes?
Type 1 diabetes is a chronic condition that affects how your body regulates blood sugar (glucose). Unlike type 2 diabetes, which is often associated with lifestyle factors, type 1 diabetes is an autoimmune disease where your body's immune system mistakenly attacks and destroys the insulin-producing cells in your pancreas.
Insulin: The Missing Piece
Insulin is a hormone that helps your body use glucose for energy. When you have type 1 diabetes, your body doesn't produce enough insulin, or it may not produce any insulin at all. This means glucose builds up in your bloodstream, leading to high blood sugar levels.
Signs and Symptoms
The classic symptoms of type 1 diabetes are often referred to as the "3 Ps":
1. Polyuria: Frequent urination
2. Polydipsia: Increased thirst
3. Polyphagia: Increased hunger
Other symptoms may include:
- Unexplained weight loss
- Fatigue
- Blurred vision
- Slow-healing sores
- Frequent infections
Complications of Type 1 Diabetes
If left untreated, type 1 diabetes can lead to serious complications:
Diabetic ketoacidosis (DKA): A life-threatening condition that occurs when your body produces high levels of ketones, a byproduct of fat breakdown.
Heart disease: High blood sugar levels can damage blood vessels and increase your risk of heart attack and stroke.
Kidney disease: High blood sugar levels can damage your kidneys, leading to kidney failure.
Nerve damage (neuropathy): High blood sugar levels can damage nerves throughout your body, causing numbness, tingling, and pain.
Eye damage (retinopathy): High blood sugar levels can damage the blood vessels in your eyes, leading to vision loss.
Managing Type 1 Diabetes
There is currently no cure for type 1 diabetes, but it can be managed with careful attention to blood sugar levels, insulin therapy, and a healthy lifestyle.
Insulin Therapy: Insulin is administered through injections or an insulin pump. There are several types of insulin, each with its own duration of action and peak effect.
Regular Insulin: Short-acting insulin used before meals.
NPH Insulin: Intermediate-acting insulin that provides longer-lasting coverage.
Humalog/Lispro: Rapid-acting insulin that starts working quickly after injection.
Lantus/Glargine: Long-acting insulin that provides a steady level of insulin throughout the day.
Blood Sugar Monitoring: Regular blood sugar monitoring is essential for managing type 1 diabetes. This involves pricking your finger to obtain a blood sample and testing it with a glucose meter.
Healthy Lifestyle: A healthy lifestyle can help improve blood sugar control and overall health. This includes:
- Eating a balanced diet
- Exercising regularly
- Maintaining a healthy weight
- Managing stress
Somogyi Effect
Description: This occurs when blood sugar levels drop too low in the middle of the night (around 2-4 am), triggering a release of counter-regulatory hormones like glucagon. These hormones cause a rebound rise in blood sugar levels, leading to hyperglycemia in the morning.
Symptoms: Night sweats, morning hyperglycemia.
Treatment: Reduce evening insulin dose or have a smaller snack before bedtime.
Dawn Phenomenon
Description: This is a natural rise in blood sugar levels in the early morning hours due to the release of growth hormones. In people with diabetes, this can lead to hyperglycemia.
Symptoms: Morning hyperglycemia.
Treatment: Increase the amount of insulin at bedtime, eat a smaller snack before bedtime, or change the timing of insulin administration.
Hypoglycemia
Description: This occurs when blood sugar levels drop below 70 mg/dL. It can be caused by inadequate nutrition, excessive exercise, insulin overdose, or certain medications.
Symptoms: Cool and clammy skin, sweating, pallor, irritability, hunger, lack of coordination, and sleepiness.
Treatment: Follow the "Rule of 15":
1. Eat or drink 15 grams of carbohydrates.
2. Wait 15 minutes.
3. Check blood sugar again.
4. If still below 70 mg/dL, repeat steps 1-3.
If the person is unable to swallow or is unconscious, administer glucagon 1 mg subcutaneously or intramuscularly, or 0.5 mg intravenously.
Diabetes Mellitus - Symptoms, Causes, Treatment, and Prevention
Type 2 Diabetes
Description: Type 2 diabetes is a chronic condition that affects how your body regulates blood sugar (glucose). Unlike type 1 diabetes, where the body doesn't produce enough insulin, in type 2 diabetes, the body either doesn't produce enough insulin or the insulin that is produced doesn't work properly (insulin resistance).
Signs and Symptoms:
The classic symptoms of type 2 diabetes are often referred to as the "3 Ps":
1. Polyuria: Frequent urination
2. Polydipsia: Increased thirst
3. Polyphagia: Increased hunger
Other symptoms may include:
- Fatigue
- Blurred vision
- Slow-healing sores
- Frequent infections
In some cases, type 2 diabetes may develop without any noticeable symptoms.
Complications of Type 2 Diabetes
If left untreated, type 2 diabetes can lead to serious complications:
Heart disease: High blood sugar levels can damage blood vessels and increase your risk of heart attack and stroke.
Kidney disease: High blood sugar levels can damage your kidneys, leading to kidney failure.
Nerve damage (neuropathy): High blood sugar levels can damage nerves throughout your body, causing numbness, tingling, and pain.
Eye damage (retinopathy): High blood sugar levels can damage the blood vessels in your eyes, leading to vision loss.
Hyperosmolar Hyperglycemic Nonketotic State (HHNK): This is a life-threatening condition that can occur in people with type 2 diabetes who have very high blood sugar levels but don't produce ketones.
Managing Type 2 Diabetes
Type 2 diabetes can often be managed through lifestyle changes and medication.
Healthy Lifestyle: A healthy lifestyle can help improve blood sugar control and overall health. This includes:
- Eating a healthy diet
- Exercising regularly
- Maintaining a healthy weight
- Managing stress
Medication: Depending on the severity of the condition, your doctor may prescribe oral medications or insulin to help control your blood sugar levels.
