Have you ever felt excessively thirsty or had the urge to urinate frequently? Maybe you’ve noticed unexplained weight loss or fatigue that you can’t seem to shake. If so, you could be showing early signs of diabetes.
Diabetes is a chronic disease that affects how your body turns food into energy. Don’t panic – the good news is diabetes is manageable. But the first step is learning the facts. What exactly is diabetes, what causes this condition, and how is it treated? This guide will walk you through the basics of diabetes, including the differences between type 1 and type 2 diabetes, common symptoms to watch out for, diagnosis, treatment options, and lifestyle changes you can make to prevent or manage the disease. The more you know about diabetes, the better equipped you’ll be to take control of your health.
What Is Diabetes?
Diabetes is a chronic disease that occurs when your blood sugar levels are too high. It means your body has trouble turning the food you eat into energy. The food you eat is broken down into sugar (glucose) and released into your bloodstream. Your pancreas then produces insulin to help glucose enter your cells.
If you have diabetes, your body either doesn’t make enough insulin or can’t use the insulin it makes as well as it should. When there isn’t enough insulin or cells stop responding to insulin, too much blood sugar stays in your bloodstream. Over time, this can cause health problems like heart disease, vision loss, and kidney disease.
Diabetes Symptoms: Signs to Watch Out For
Diabetes can be a confusing condition, but knowing the symptoms can help you catch it early. The most common signs to watch out for include:
- Increased thirst and frequent urination. If you find yourself suddenly drinking and peeing more often, it could indicate high blood sugar.
- Increased hunger. When your cells can’t access the glucose in your bloodstream, your body signals that it needs more food. Feeling hungry all the time is not normal and could be a warning sign.
- Fatigue. No matter how much you rest, you still feel tired and drained of energy. This can happen when your cells aren’t receiving the fuel they need.
- Blurry vision. High blood sugar can cause fluid shifts in your eyes that blur your vision. This symptom often develops slowly, so you may not notice the change right away.
- Slow wound healing. High blood sugar impairs your body’s ability to heal cuts, scrapes, and injuries. Even small cuts can take weeks to heal and may become infected more easily.
- Numbness or tingling. Excess sugar in your blood can damage your nerves, causing numbness, especially in your extremities like hands and feet. This condition is known as diabetic neuropathy.
Diabetes symptoms may appear abruptly in some people or develop slowly in others over the course of several weeks or months. Don’t ignore these signs, see your doctor right away for a blood sugar test and diagnosis. Catching diabetes early gives you the best chance of gaining control of your health. The good news is diabetes can be managed well with proper treatment and lifestyle changes.
Diabetes Causes and Risk Factors: What Increases Your Risk?
Diabetes doesn’t just happen overnight. Several factors can increase your risk of developing this serious disease over time. The major contributors fall into two categories: things you can’t control and lifestyle habits.
Age is one risk factor you can’t control. As you get older, especially over age 45, your risk goes up. Family history also plays a role. If your parents, siblings or children have diabetes, you’re more prone to developing it yourself. Ethnicity is another factor, as diabetes is more common in African Americans, Hispanic Americans, Native Americans, and Asian Americans.
Some lifestyle habits that increase your risk include:
- Being overweight or obese. Excess weight, especially in the abdomen, increases insulin resistance and blood sugar levels. Losing just 5-10 pounds can help lower your risk.
- Physical inactivity. Exercise helps your body use insulin and control blood sugar levels. Aim for at least 30 minutes of moderate activity most days of the week. Walking, biking and swimming are all great options.
- Unhealthy diet. A diet high in calories, fat and sugar but low in nutrients promotes weight gain and diabetes risk. Focus on lean proteins, high-fiber whole grains, fruits and vegetables. Limit red meat, sweets and sugary drinks.
- Smoking. Smoking significantly increases your risk and makes diabetes harder to control. Ask your doctor for help quitting smoking.
- High blood pressure. Uncontrolled high blood pressure damages blood vessels and stresses your body’s systems. Work with your doctor to get your blood pressure down to a healthy range.
- High cholesterol levels. High cholesterol contributes to plaque buildup in arteries and can lead to heart disease. Cholesterol-lowering medication and lifestyle changes may be needed to reduce your diabetes risk.
By understanding the factors that increase your chance of diabetes and making positive lifestyle changes, you can take control of your health and lower your risk. Diabetes may still develop due to circumstances outside of your control, but you’ll have the best odds of avoiding or delaying this condition and living well.
Diabetes Diagnosis and Testing: How Doctors Check for Diabetes
Getting diagnosed with diabetes usually starts with your doctor ordering blood tests to check your blood sugar levels and other health indicators. The most common tests are:
A1C test
The A1C test measures your average blood sugar levels over the past 2 to 3 months. An A1C of 6.5% or higher indicates diabetes. This test is often used to diagnose type 2 diabetes and monitor how well you’re managing your diabetes.
Fasting blood sugar test
A fasting blood sugar test measures your blood glucose levels after 8 hours of fasting. A level of 126 milligrams per deciliter (mg/dL) or higher on two separate days means you likely have diabetes. This test is usually done first thing in the morning before eating or drinking anything.
Oral glucose tolerance test
This test measures how your body responds to sugar. You’ll drink a sugary liquid and have your blood sugar tested after 2 hours. A reading of 200 mg/dL or higher indicates diabetes. This test is often used to diagnose type 2 diabetes or gestational diabetes during pregnancy.
Random blood sugar test
A random blood sugar test measures your blood sugar levels at any time of day. A level of 200 mg/dL or higher, plus signs and symptoms of diabetes like increased thirst, frequent urination, and unexplained weight loss may indicate diabetes. This test is not as accurate as the fasting blood sugar or A1C tests and is usually followed up with additional testing.
Once diagnosed, your doctor will determine what type of diabetes you have and the severity in order to develop the best treatment plan for you. Early diagnosis and proper management of diabetes is key to controlling symptoms, reducing health risks, and maintaining the best quality of life.
Diabetes Types: Type 1 vs Type 2 Diabetes Mellitus
There are two main types of diabetes: type 1 and type 2. Both types of diabetes mellitus cause high blood sugar levels, but the underlying causes and treatments differ.
Type 1 Diabetes
Type 1 diabetes, also known as juvenile diabetes or insulin-dependent diabetes, occurs when the immune system destroys the cells in the pancreas that produce insulin. This usually happens in children and young adults, though it can appear at any age.
With type 1 diabetes, your pancreas produces little or no insulin. This results in a buildup of glucose in the bloodstream since insulin is required for cells to be able to use glucose for energy. If left untreated, type 1 diabetes is life-threatening. Treatment focuses on replacing the insulin through injections or an insulin pump, as well as managing blood sugar levels with diet and lifestyle changes.
Type 2 Diabetes
Type 2 diabetes, also known as adult-onset diabetes, develops over time and is usually seen in older or overweight individuals. It occurs when the body becomes resistant to insulin or doesn’t make enough insulin. Often there are no symptoms, so many people live with the condition for years before being diagnosed.
With type 2 diabetes, your body still produces insulin but is unable to use it effectively. This is known as insulin resistance. Initially, the pancreas will produce more insulin to overcome this resistance but over time, it loses the ability to produce enough insulin. Treatment focuses on diet and exercise, oral medications, and insulin injections or pumps. Losing excess weight and making healthy lifestyle changes can help manage or even reverse type 2 diabetes.
The key differences to remember are:
- Type 1 diabetes is an autoimmune disease where the body attacks insulin-producing cells. Type 2 diabetes is a metabolic disorder where the body becomes insulin resistant or doesn’t produce enough insulin.
- Type 1 diabetes usually appears in children and young adults. Type 2 diabetes primarily develops in older, overweight individuals.
- Type 1 diabetes is always treated with insulin injections. Type 2 diabetes can often be managed with oral medications and lifestyle changes, at least initially.
While the types of diabetes differ, the goal of treatment is the same, ”to keep your blood sugar levels within a healthy range”. Careful management of diabetes, no matter the type, is critical to prevent complications and maintain your health and quality of life.
Diabetes Treatment: Medications and Lifestyle Changes
Diabetes treatment typically involves medications and lifestyle changes to help manage your blood sugar levels. The good news is there are many options to choose from, so you and your doctor can find the right combination for you.
Medications
There are several types of medications for diabetes, including:
- Oral medications like metformin, sulfonylureas, and thiazolidinediones help your body produce more insulin or use insulin more efficiently.
- Injectable insulin comes in various types like long-acting, short-acting, and rapid-acting. Insulin injections help supplement or replace your body’s own insulin.
- Other injectables like GLP-1 receptor agonists stimulate the release of insulin from your pancreas.
Your doctor will determine which medication(s) and dosage is right based on your diabetes type, lifestyle, and other health factors. Medications may need to be adjusted over time as your condition changes.
Lifestyle Changes
Making certain lifestyle changes can also help manage diabetes and improve your health. Some recommended changes include:
- Following a healthy diet low in sugar, refined carbs, and unhealthy fats. Focus on vegetables, fruits, whole grains, and lean proteins.
- Engaging in regular exercise most days of the week. Even light activity like walking, biking, or yoga can help. Aim for at least 30 minutes a day 5 days a week.
- Losing excess weight which can make it easier for your body to produce and use insulin. Losing just 5-10% of your weight can make a difference.
- Not smoking. Smoking increases health risks for diabetics and makes management of blood sugar more difficult. Seek help to quit smoking.
- Reducing stress through relaxation techniques like meditation, deep breathing, or journaling. High stress can spike blood sugar.
- Monitoring your blood sugar levels as directed by your doctor. Keeping close track of levels helps determine if adjustments need to be made to your treatment plan.
By following your doctor’s recommended treatment plan, including both medications and lifestyle changes, you can successfully manage your diabetes, avoid complications, and live a long and healthy life. The key is sticking with the plan you’ve got this!
Diabetes Diet: Healthy Foods to Eat and Avoid
A diabetes diet focuses on eating healthy foods that are high in nutrients but moderate in calories and carbs. The goal is to keep your blood sugar in a healthy range while providing your body with the energy and nutrients it needs. Some key things to focus on in your diet include:
Watching your carb intake
Aim for 45-60 grams of carbs per meal. Focus on complex carbs like whole grains, beans, and starchy veggies. Limit simple carbs from sweets and sugary drinks.
Choosing lean proteins
Pick proteins like fish, chicken, eggs, and legumes. Limit red meat and full-fat dairy.
Eating healthy fats
Choose unsaturated fats from avocados, nuts, and olive oil. Limit saturated fat from red meat and full-fat dairy.
Adding fiber and nutrients
Eat lots of non-starchy veggies, fruits, and leafy greens. They provide fiber, vitamins, and minerals without spiking blood sugar.
Staying hydrated
Drink plenty of water and other non-caloric beverages to keep you hydrated without adding extra sugar.
Foods to limit or avoid:
- Sugary foods like candy, cookies, and sugary cereals
- Starchy, white flour foods such as white bread and white rice
- Fried foods which are high in unhealthy fats
- Red meat which is high in saturated fat
- Full-fat dairy products made from whole milk
- Packaged snacks like chips, pretzels, and crackers which are high in salt, fat and calories but low in nutrients.
Making healthy changes to your diet can have a big impact on your diabetes management and health. Work with your doctor or nutritionist to develop a meal plan that works for you. Be patient through the process, as it can take time to adjust. But sticking to a balanced diabetes diet will help you gain better control of your blood sugar and feel your best.
Diabetes Complications: Problems Associated With High Blood Sugar
Diabetes complications can arise when high blood sugar levels persist for long periods of time. As the condition progresses, it can damage blood vessels, nerves, and organs in your body. The higher your blood sugar levels and the longer you’ve had diabetes, the greater your risk of developing complications.
Eye problems
High blood sugar can damage the tiny blood vessels in your eyes that are important for vision. This can lead to eye conditions like diabetic retinopathy, glaucoma, and cataracts. Regular eye exams are critical to catch any issues early. Controlling your blood sugar, blood pressure, and cholesterol can help prevent or slow the progression of eye disease.
Kidney disease
The kidneys act as filters to remove waste from your blood. High blood sugar damages the kidneys’ filtering system, causing waste and fluid to build up in the body. This can lead to kidney failure over time if left untreated. Medication and lifestyle changes may be needed to manage kidney problems. Dialysis or a kidney transplant could become necessary in severe cases.
Nerve damage
Uncontrolled blood sugar levels can damage the nerves in your body, especially those in your legs and feet. This is known as diabetic neuropathy. You may experience numbness, pain, and impaired sensation. Nerve damage can make it difficult to detect injuries or temperature changes in your extremities. Careful foot care and keeping blood sugar in a healthy range can help prevent or delay nerve damage.
Heart disease
High blood sugar contributes to atherosclerosis or hardening of the arteries. This can lead to coronary artery disease, heart attack, and other cardiovascular problems. Controlling cholesterol and blood pressure, quitting smoking, eating healthy, and exercising regularly can lower your risk of heart disease and other diabetes complications.
Monitoring blood sugar levels, following your doctor’s recommendations, and making healthy lifestyle changes can help prevent or delay the onset of diabetes complications. Be sure to get regular medical checkups and testing to catch any problems early on. The earlier complications are detected, the easier they are to treat and manage.
Diabetes FAQs: Common Questions About Symptoms, Medications and More
You probably have a lot of questions about diabetes and how it may affect your life. Here are some of the most frequently asked questions about diabetes symptoms, medications, and management.
Do I have to take insulin if I have diabetes?
Not necessarily. There are several treatment options for diabetes. For type 1 diabetes, insulin injections are required. For type 2 diabetes, other options include oral medications, insulin, lifestyle changes like diet and exercise, or a combination of these treatments. Your doctor will determine the best course of treatment based on your blood sugar levels, health conditions, lifestyle, and personal preferences.
What are the warning signs of high or low blood sugar?
Some common symptoms of high blood sugar (hyperglycemia) include increased thirst, frequent urination, blurred vision, and fatigue. For low blood sugar (hypoglycemia), watch for dizziness, shaking, sweating, rapid heartbeat, and confusion. Check your blood sugar levels if you experience any of these signs and treat as directed by your doctor.
How often do I need to check my blood sugar?
How frequently you check your blood sugar will depend on your diabetes management plan from your doctor. For those on insulin or certain oral medications, checking 3-4 times per day (before meals and at bedtime) is typical. For diet-controlled type 2 diabetes, once or twice daily may be sufficient. Be sure to talk to your doctor about a testing schedule that is right for you based on your treatment plan and to determine specific target blood sugar levels.
Can I still eat sweets or carbs if I have diabetes?
You can eat limited amounts of sweets or carbs in moderation as part of your diabetes diet plan. The key is to balance them with other healthy foods, watch your portion sizes, and account for them in your meal plan. Choose sweets that are high in nutrients and low in sugar, fat and calories. And always check your blood sugar levels frequently after eating sweets to make sure they stay in your target range. The best approach is to work with your doctor or dietitian to develop an eating plan that allows for occasional sweets but still keeps your blood sugar well controlled.
