Understanding Diabetes: Symptoms, Causes, Treatment, and Living with Diabetes

Understanding Diabetes

Diabetes is a chronic health condition that affects how the body turns food into energy. With diabetes, the body either doesn't make enough insulin or can't effectively use the insulin it produces. Insulin is a hormone made in the pancreas that allows sugar from food to enter the body's cells and be used for energy.

When sugar can't get into the cells, it builds up in the bloodstream. This is known as high blood sugar or hyperglycemia. Over time, high blood sugar levels can cause serious health problems like heart disease, vision loss, kidney disease, and nerve damage.

There are a few different types of diabetes:

Type 1 Diabetes

Type 1 diabetes is an autoimmune disease where the immune system attacks and destroys the insulin-producing cells in the pancreas. This means people with type 1 diabetes don't make any insulin. It usually develops in childhood or young adulthood but can appear at any age. People with type 1 diabetes need to take insulin every day to survive.

Type 2 Diabetes

Type 2 diabetes develops over many years, often from lifestyle factors like obesity, lack of exercise, and poor diet. With type 2 diabetes, the body doesn't use insulin effectively. At first, the pancreas makes more insulin to try to keep up with the increased need. Eventually it can't produce enough insulin to control blood sugar levels.

Gestational Diabetes

Gestational diabetes occurs during pregnancy when the body can't make enough insulin to handle the extra blood sugar levels from the placenta. It usually resolves after delivery but increases the risk of both mother and baby developing type 2 diabetes later.

Prediabetes

Prediabetes means blood sugar levels are higher than normal but not high enough for a diagnosis of diabetes. Making lifestyle changes at the prediabetes stage can prevent or delay the onset of type 2 diabetes.

Diabetes Symptoms

The most common diabetes symptoms include:

• Frequent urination
• Increased thirst and hunger
• Fatigue
• Blurred vision
• Slow healing of cuts and bruises
• Tingling, pain, or numbness in hands and feet

Symptoms can develop rapidly with type 1 diabetes. But with type 2, they tend to come on more gradually, which is why many people don't realize they have diabetes for years.

Diabetes Diagnosis

Doctors use blood tests to diagnose diabetes. They measure levels of glycated hemoglobin (A1C) and blood glucose to screen for and monitor the condition. An A1C test provides an average of blood sugar levels over the past 2-3 months. Its used to diagnose prediabetes and diabetes:

• Prediabetes: A1C between 5.7-6.4%
• Diabetes: A1C 6.5% or higher on two separate tests

A fasting blood glucose test can also diagnose diabetes. Blood is drawn after an 8-hour fast and a level of 126 mg/dL or higher indicates diabetes.

An oral glucose tolerance test involves drinking a sugary drink then checking blood sugar levels after two hours. This identifies diabetes and prediabetes.

Random blood sugar testing can screen for diabetes but doesnt provide a diagnosis. Levels over 200 mg/dL when accompanied by symptoms can indicate diabetes.

Treatment for Diabetes

While there is no cure for diabetes, treatment aims to keep blood sugar levels as close to normal as possible to prevent complications. Treatment varies based on the type of diabetes.

Type 1 Diabetes Treatment

People with type 1 diabetes require insulin injections or use of an insulin pump multiple times a day. The goal is to match the timing and amount of insulin to carbohydrate consumption, exercise, illness, and other factors that affect blood sugar.

Following a healthy meal plan, getting regular physical activity, and maintaining a healthy weight are also important for managing type 1 diabetes. People with type 1 diabetes need to check blood sugar levels several times a day and work closely with their healthcare team.

Type 2 Diabetes Treatment

Treatment for type 2 diabetes focuses on meal planning, physical activity, and in many cases, diabetes medications and/or insulin therapy:

• Healthy eating. Following a balanced diet helps manage blood sugar levels and weight.
• Exercise. Getting regular physical activity helps the body use insulin and control blood sugar levels.
• Medications. Many people with type 2 diabetes take metformin, glucagon-like peptide-1 (GLP-1) agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors, sodium-glucose cotransporter 2 (SGLT2) inhibitors, sulfonylureas, or other oral medications.
• Insulin. Some people with type 2 diabetes require insulin injections or use of an insulin pump to reach blood glucose targets.

Gestational Diabetes Treatment

Gestational diabetes is treated with meal planning, physical activity, and blood sugar monitoring. Some women also need diabetes medications or insulin therapy. Treatment aims to keep blood sugar levels in a healthy range for the health of both mother and baby.

Diabetes Complications

Consistently high blood sugar levels can lead to serious diabetes complications over time. But the risk of complications drops significantly with proper treatment and control of blood sugar, blood pressure, and cholesterol.

Some potential diabetes complications include:

Cardiovascular Disease

High blood sugar damages blood vessels and the nerves that control the heart. It also increases cholesterol levels and blood pressure. This raises the risk of heart attack, stroke, and other cardiovascular problems.

Nerve Damage (Neuropathy)

Excess sugar can damage the walls of the tiny blood vessels that supply nerves, especially in the legs. This can cause tingling, numbness, pain, and weakness. Nerve damage can also lead to problems with digestion, urination, and erectile function.

Kidney Disease (Nephropathy)

The kidneys filter waste from the blood, but high blood sugar can damage these filters. Severe damage can lead to kidney failure or irreversible end-stage kidney disease, requiring dialysis or a kidney transplant.

Eye Damage (Retinopathy)

Diabetes affects the small blood vessels in the retina of the eyes. This can result in vision impairment or blindness. Screening and timely treatment for diabetic retinopathy with laser therapy and surgery can prevent vision loss.

Foot Damage

Nerve damage in the feet coupled with reduced blood flow increases the risk of various foot complications. Blisters, cuts, and sores can become infected and lead to ulcers or gangrene. Improving circulation and foot care can prevent amputation.

Reducing Diabetes Complications

While diabetes complications can be frightening, there are many ways to reduce risks:

• Monitor blood sugar levels and take medications as prescribed.
• Follow your diabetes meal plan.
• Get regular physical activity.
• Aim for healthy body weight.
• Quit smoking and limit alcohol.
• Control blood pressure and cholesterol levels.
• Get routine eye, foot, and dental exams.
• Attend all medical appointments.
• Learn to identify signs of low blood sugar.

Work closely with your healthcare team and follow an individualized diabetes treatment plan to prevent or delay the onset of complications.

Living with Diabetes

Although diabetes is a serious disease, you can still live a long and healthy life by making smart day-to-day choices. Things that can help life with diabetes include:

Eating Healthy

Following a diabetes meal plan helps manage blood sugar levels and weight. Meals should include lean protein, complex carbs, and healthy fats. Portion sizes matter as well.

Staying Active

Getting regular exercise provides cardiovascular, weight loss, and blood sugar benefits. Aim for at least 30 minutes of physical activity most days of the week.

Taking Medications

Insulin and other diabetes medications help keep blood sugar levels on target. Take them exactly as prescribed.

Reducing Stress

Learning healthy coping strategies for stress can help stabilize blood sugar levels.

Quitting Smoking

Smoking raises risks for diabetes complications. A combination of nicotine replacement, support programs, medication, and/or counseling can help you quit.

Seeing Your Doctor

Attend recommended doctor visits to properly monitor diabetes. Report any concerning symptoms promptly.

Checking Blood Sugars

Routinely check blood glucose levels at home and keep a log of the results. Share them with your healthcare team.

Problem Solving

Identify challenges and develop plans to overcome obstacles to treatment and self-care.

Healthy Coping

Learn techniques to manage stress levels, avoid burnout, and find support. Emotional health affects physical health.

Sufficient Sleep

Get 7-8 hours of sleep per night. Manage sleep apnea or insomnia issues.

Support for Living with Diabetes

Living with diabetes is difficult but many resources exist to help:

• Diabetes education programs
• Apps to track nutrition, activity, medications, and blood sugar
• Glucose monitoring devices and insulin delivery systems
• Nutrition counseling
• Fitness trainers knowledgeable about diabetes
• Diabetes support groups
• Stress management guidance
• Smoking cessation programs
• Online forums for advice and information

Build your own support team including healthcare providers, family, and friends. Having assistance and encouragement along your diabetes journey makes a big difference.

Outlook for Diabetes

While diabetes remains a lifelong condition, treatment has advanced tremendously over the years. Improved medications, insulin delivery methods, glucose monitoring technology, and education programs empower people to manage their diabetes effectively.

Research on new medications, pancreatic cell transplants, artificial pancreas systems, and even a cure continues. By taking advantage of all the tools available today, most people with diabetes can live long, satisfying lives.

The key is learning all you can about diabetes, working closely with your healthcare providers, and making self-management an important priority.
