How many types of diabetes are there?

• Diabetes is a chronic condition where the body cannot effectively manage blood sugar due to a lack of insulin from the pancreas or insulin resistance in cells. This causes abnormally high levels of sugar to accumulate in the bloodstream over extended periods.
• How many types of diabetes are there? There are four types Type 1 diabetes, Type 2 diabetes, gestational diabetes, and other types of diabetes.
• How to check for diabetes Observe for abnormal symptoms, assess risk factors, perform fingerstick blood sugar tests using urine test strips, and have annual health checkups.
• Foods suitable for people with diabetes include complex carbohydrates, leafy green vegetables, colorful vegetables, low-sugar fruits, lean protein, nuts and grains, healthy fats, low-fat milk, and fat-free milk.

Diabetes isn't just about eating too many sweets; it's a condition where the body has abnormally high blood sugar levels. If left untreated, it can affect vital organs throughout the body. Diabetes can be categorized according to its cause, each type stemming from different factors and requiring different treatments. This article will answer the questions about the different types of diabetes.

What is Diabetes?

Diabetes is a chronic condition where the body cannot effectively manage blood sugar due to a lack of insulin from the pancreas or insulin resistance in cells. This leads to abnormally high levels of sugar accumulating in the bloodstream over extended periods. If left uncontrolled, excessively high sugar levels gradually damage vital organs such as the heart, kidneys, eyes, and nervous system, leading to dangerous complications.

How Many Types of Diabetes Are There?

When talking about diabetes, many people may wonder how many types of diabetes there are. Each type is categorized according to the disease mechanism, risk groups, and different treatment methods. Therefore, an accurate diagnosis is necessary to receive appropriate treatment for diabetes. Diabetes can be divided as follows

Type 1 Diabetes

This is caused by the immune system destroying pancreatic cells, resulting in the inability to produce insulin at all or producing very little. It is often found in children or people under 40 years old. They are often thin and experience sudden, severe symptoms such as frequent urination, excessive thirst, and rapid weight loss. This type of diabetes requires lifelong insulin injections. If medication is missed, it can lead to diabetic ketoacidosis (DKA), which is dangerous and can cause unconsciousness or death.

Type 2 Diabetes

This is the most common type of diabetes. It is caused by insulin resistance combined with a fatigued pancreas that produces less insulin. It is often associated with adults over 40 who are overweight, lack exercise, or have a genetic predisposition. Treatment usually begins with lifestyle changes such as diet and exercise, along with oral medications to lower blood sugar. However, if left untreated until the pancreas deteriorates, doctors may consider prescribing insulin injections as well.

Gestational Diabetes

Gestational diabetes during pregnancy Type 2 diabetes is a condition of high blood sugar first detected during pregnancy, usually in the second or third trimester. This is due to hormonal changes in the placenta that increase the mother's insulin resistance. Although blood sugar levels usually return to normal after delivery, poor control can lead to macrosomia (large baby), causing difficult delivery, and increases the risk of both mother and child developing type 2 diabetes in the future.

Other types of diabetes

These are less common types with specific causes requiring diagnosis by a specialist. Examples include

• Genetic abnormalities, such as MODY diabetes, which is often found in younger people but has a different mechanism from type 1.
• Pancreatic diseases, such as chronic pancreatitis, pancreatic surgery, or tumors.
• Other hormonal abnormalities, such as high cortisol levels (Cushing's Syndrome) or hyperthyroidism.
• Currently, certain medications, especially steroids, some diuretics, or anti-organ rejection drugs.

Severity of each type

All types of diabetes are equally dangerous if chronically high blood sugar levels occur, as they can lead to serious complications affecting the eyes, kidneys, heart, brain, and blood vessels, potentially resulting in disability or death. The severity depends on blood sugar control and the duration of the disease. And other co-morbidities such as high blood pressure or high cholesterol are the main factors.

The severity of each type is divided as follows

• Type 1 diabetes The body completely lacks insulin. This group must rely on insulin injections for life. Even a short period of missed medication puts them at risk of diabetic ketoacidosis (DKA), which can lead to unconsciousness and rapid death.
• Type 2 diabetes This is the most common type. It often develops gradually, often without the patient being aware. High blood sugar levels accumulate and gradually damage blood vessels and organs, increasing the long-term risk of kidney failure, blindness, heart attack, and stroke.
• Gestational diabetes The severity focuses on complications during pregnancy and childbirth, such as macrosomia (abnormally large babies), difficult delivery, or preeclampsia. Although blood sugar levels usually return to normal after birth, it increases the risk of both the mother and child developing type 2 diabetes in the future.
• Other types of diabetes The severity depends on the underlying disease, such as pancreatic cancer or the use of steroids. This makes blood sugar control more difficult than usual and requires treatment for both the diabetes and the underlying disease, resulting in a higher burden on the body and a higher risk of complications.

Early signs and symptoms of diabetes to watch for

• Abnormally frequent urination, both day and night, especially waking up multiple times during the night to urinate.
• Excessive thirst and dry throat; needing to drink more water than usual but still feeling thirsty.
• Frequent hunger but lack of energy; increased appetite but still feeling weak and easily tired.
• Unusual weight loss; rapid weight loss without intentionally losing weight or increasing exercise.
• Blurred vision; sudden worsening of vision or difficulty seeing clearly when blood sugar is high.
• Easy fatigue, weakness, excessive sweating; feeling more exhausted than usual during daily activities.
• Numbness, burning, or tingling sensations in the hands and feet.
• Slow wound healing; chronic wounds that are difficult to heal, especially on the feet; frequent skin and vaginal infections.
• Itching; increased susceptibility to fungal infections in moist areas or areas prone to itching.

Who is at risk of developing diabetes?

• People aged 35–40 and older, with the risk increasing with age.
• People with a BMI over 23 or a waist circumference exceeding the standard (men > 90 cm, women > 80 cm).
• A family history of diabetes in a direct relative (parents, siblings, etc.).
• People with high blood pressure or abnormal blood lipid levels (high triglycerides/low HDL).
• Lack of exercise and prolonged sitting.
• A high-sugar diet, refined carbohydrates, and high-fat foods.
• A history of gestational diabetes, giving birth to a child weighing over 4 kg, or polycystic ovary syndrome (PCOS).
• People with high fasting blood sugar levels or prediabetes.

What can people with diabetes eat?

• Complex carbohydrates such as brown rice, unpolished rice, oatmeal, whole wheat bread, and unrefined grains, which are high in fiber to slow sugar absorption.
• Green leafy vegetables and a variety of colorful vegetables such as kale, broccoli, cabbage, and cucumbers should make up the main part of your plate at every meal.
• Consume less sweet fruits such as guava, apples, rose apples, or oranges in moderation and avoid dipping them in chili salt or sugar.
• Include lean protein sources like fish, skinless chicken breast, pork tenderloin, egg whites, and tofu, focusing on boiling, steaming, or grilling.
• Polerant beans and whole grains, such as pumpkin seeds or sunflower seeds, provide both protein and healthy fats, helping you feel full longer.
• Include healthy fats like olive oil, avocado, and omega-3 fish such as salmon or mackerel to support cardiovascular health.
• For healthy beverages, choose low-fat milk, skim milk, or unsweetened soy milk.
• Suggested menu options include brown rice with grilled fish or chicken served with blanched vegetables, a low-protein vegetable salad, or clear noodle soup that is unsweetened and free of excessive fried garlic.

What to Avoid If You Have Diabetes

• High-sugar foods and drinks soft drinks, bubble tea, fruit juices, sweets, and all types of baked goods, as these cause a rapid spike in blood sugar levels.
• Refined grains white rice, noodles, white bread, and croissants should be avoided or limited in quantity because they are digested into sugar faster than unrefined grains.
• High-fat foods all types of fried foods, chicken skin, and fast food, which increase both calories and accumulated fat, increasing the risk of cardiovascular disease.
• Processed and high-sodium foods sausages, ham, bacon, instant noodles, and pickled foods increase the risk of high blood pressure and kidney disease.
• Alcoholic beverages interfere with blood sugar control and damage the liver, especially when mixed with sugary drinks or soft drinks.
• Snacks potato chips and crisps that are very salty or high in fat.

How to Do a Basic Self-Check

1. Observe for unusual symptoms such as frequent urination, excessive thirst, unusual weight loss, fatigue, slow wound healing, or recurring fungal infections.
2. Assess risk factors Check if you are over 35 years old, overweight, have a family history of diabetes, or high blood pressure and cholesterol.
3. Fingerstick blood glucose test Fast for at least 8 hours before the test. If your fasting blood sugar is higher than 126 mg/dL, see a doctor immediately.
4. Use a urine test strip. Repeatedly positive results for sugar in your urine indicate the need for a more comprehensive blood test at a hospital.
5. Get annual health checkups. Undergo tests to measure HbA1c levels or an oral glucose tolerance test (OGTT) for accurate diagnosis.

Guidelines for Diabetes Treatment

• Modify your diet Control carbohydrate intake, focusing on vegetables and whole grains. Reduce sugary, fatty, and salty foods, and eat meals at regular times.
• Exercise regularly Engage in physical activity such as brisk walking or swimming for at least 150 minutes per week, combined with resistance training to improve insulin response.
• Take prescribed medication Take your blood sugar-lowering medication regularly according to your doctor's treatment plan.
  Inject insulin For type 1 or type 2 diabetes where pancreatic function is impaired and oral medication is insufficient to control blood sugar.
• Monitor complications See your doctor regularly for checkups of your eyes, kidneys, heart, and feet to prevent organ damage in its early stages.
• Manage other risk factors Control blood pressure and cholesterol, quit smoking, and maintain a healthy weight.
• Learn and adapt over the long term. Consult a doctor to understand the disease and make appropriate and sustainable lifestyle changes.
