Diabetes affects over 38 million Americans, yet many people don’t understand the condition until they receive a diagnosis. From young adults with unexplained fatigue to older patients managing multiple health concerns, diabetes often develops silently before symptoms appear. Understanding the different types, risk factors, and whether diabetes can be reversed will help you take control of your health and prevent serious complications.
Dr. Deborah Amirtham, a physician at Tryon Medical Partners who specializes in primary care, takes a comprehensive approach to diabetes care. Her multidisciplinary perspective on treating patients across all age groups provides valuable insights into recognizing, preventing, and managing this complex metabolic disorder.
What exactly is diabetes, and what are the different types?
Understanding diabetes begins with knowing how it affects your body’s ability to regulate blood sugar. Diabetes is a condition that causes elevated sugar levels in your bloodstream. Insulin is a hormone that helps your body use sugar for energy. Diabetes happens when your body doesn’t produce enough insulin, has trouble using the insulin it makes, or produces too much sugar.
A key concept in understanding diabetes is insulin resistance. “Your body may produce insulin, but it’s not very responsive,” Dr. Amirtham notes. “Think of insulin as a key that unlocks your cells to let glucose in for energy. When cells become resistant to insulin, glucose remains in your bloodstream instead of fueling your body.”
The main types of diabetes
Type 1 and Type 2 diabetes are the primary categories, but other forms exist related to genetic effects, gestational diabetes during pregnancy, or endocrine disorders like Cushing’s syndrome. These other types of diabetes include: monogenic diabetes (rare group of disorders caused by single gene mutation), LADA (latent autoimmune diabetes diabetes in adults), neonatal diabetes (a rare condition diagnosed in infants under six months old), and prediabetes (elevated blood sugar but not yet Type 2 diabetes).
What’s the difference between Type 1 and Type 2 diabetes?
The fundamental difference lies in insulin production versus insulin resistance.
Type 1 diabetes occurs when the pancreas loses its ability to produce insulin. “With Type 1, it’s not insulin resistance but an issue with production,” Dr. Amirtham clarifies. This type can be caused by autoimmune issues that attack the pancreas and isn’t preventable. Sometimes genetics or viral infections trigger Type 1 diabetes. Because little to no insulin is produced, this condition requires lifelong insulin therapy.
Type 2 diabetes primarily involves insulin resistance. “Insulin resistance occurs when the body’s cells, particularly muscles, liver, and fat cells, become less responsive to insulin,” explains Dr. Amirtham. Over time, the pancreas compensates by producing more insulin to overcome the resistance, but this becomes insufficient, which leads to elevated blood sugar levels.
Gestational diabetes develops during pregnancy in women who didn’t previously have diabetes. While gestational diabetes typically resolves after delivery, it signals an increased risk for developing Type 2 diabetes later in life, making ongoing monitoring essential. “Patients who have gestational diabetes need to be monitored so they don’t develop Type 2 diabetes,” notes Dr. Amirtham.
When and how do doctors identify diabetes concerns?
Diabetes often develops before symptoms appear, making proactive screening crucial.
“Either patients are already diagnosed or present with conditions that signify there might be an underlying disease,” Dr. Amirtham explains. “Most of the time, especially with Type 2 diabetes, patients can be hyperglycemic (have high blood sugar) without any symptoms.”
When evaluating patients, Dr. Amirtham asks critical questions: What are their other health conditions, if any? What is their lifestyle like? “We like to take a multidisciplinary approach and provide comprehensive care,” she notes, recognizing the effects of diabetes in multiple aspects of health.
Is Type 2 diabetes genetic? What causes diabetes, and can it be prevented?
The causes of diabetes differ significantly between types, and prevention strategies vary accordingly.
Type 1 diabetes: Not preventable
Type 1 diabetes is an autoimmune condition in which the immune system mistakenly attacks insulin-producing cells in the pancreas. While genetics and certain viral infections can increase the risk, there is currently no known way to prevent Type 1 diabetes. Once diagnosed, people require lifelong insulin therapy. While healthy habits help manage overall health and prevent type 2 diabetes, they don’t stop the onset of Type 1 diabetes. There is ongoing research to find ways to intervene, especially in high-risk individuals.
Type 2 diabetes: Prevention is possible
Is Type 2 diabetes genetic? Type 2 diabetes does have a genetic component, meaning family history significantly increases the risk of developing diabetes in the future. You inherit a predisposition, but environmental triggers such as diet, body weight, and exercise level, often shared within families, are crucial for the development of the disease. However, genes alone do not determine the outcome. In many cases, Type 2 diabetes can be delayed or prevented through healthy habits.
According to the American Diabetes Association, prevention strategies include:
- Regular exercise: Physical activity increases insulin sensitivity
- Nutrition: A balanced diet helps maintain healthy blood sugar levels
- Reduce smoking: Tobacco use increases diabetes risk
- Lower blood pressure: Managing hypertension reduces overall risk
While you can’t change your genetic predisposition, you can modify lifestyle factors that significantly impact whether Type 2 diabetes develops.
What’s the relationship between weight and diabetes?
Weight plays a significant role in Type 2 diabetes, but it’s more complex than simply “obesity causes diabetes.”
Excess weight, particularly around the abdomen, contributes to insulin resistance. Fat cells, especially visceral fat surrounding organs, release inflammatory substances that interfere with insulin signaling. This makes it harder for your body to use insulin effectively.
Can skinny people get diabetes?
Yes. While excess weight increases risk, Type 2 diabetes can affect people at any weight. Factors like genetics, body fat distribution (where you carry fat matters more than total weight), muscle mass, and overall metabolic health all play roles. While maintaining a healthy weight through nutrition and exercise helps prevent and manage Type 2 diabetes, it’s not the only factor to consider.
For Type 1 diabetes, weight isn’t a causative factor at all; it’s an autoimmune condition unrelated to body size.
How is diabetes treated? Can diabetes be reversed?
Treatment approaches differ based on diabetes type, and the potential for reversal depends on which type you have.
Type 1 diabetes treatment
For Type 1, you primarily take insulin. Since the pancreas produces little to no insulin, daily insulin therapy is essential and lifelong. Type 1 diabetes cannot be reversed, but it can be well-controlled with proper insulin management, blood sugar monitoring, and lifestyle adjustments.
Type 2 diabetes treatment: A comprehensive approach
Can diabetes be reversed? For Type 2 diabetes, the answer is encouraging. Yes, people with type 2 diabetes can often be in remission. While this does not “reverse” diabetes, remission means blood sugar levels return to a healthy range without medication, but it’s not a permanent “cure” as the underlying risk factors remain.
Treatment begins with non-pharmaceutical interventions:
- Medical nutrition therapy: Working with healthcare providers to develop an eating plan that manages blood sugar while providing proper nutrition.
- Regular exercise regimen: Exercise increases insulin sensitivity and promotes weight loss, two critical factors in managing Type 2 diabetes. Even a modest weight loss of 5–7% can significantly lower your risk. Dr. Amirtham recommends a combination of aerobic (walking, swimming, cycling) and strength training (weightlifting, using resistance bands, bodyweight exercises), aiming for at least 150 minutes of moderate-intensity aerobic activity per week and 2-3 resistance training sessions per week. “Cardiovascular activity is great, but it is important to do resistance exercises (a type of physical activity that trains muscles to contract against an external force) because this will increase metabolic activity,” Dr. Amirtham advises.
- Mental health support: “Sometimes people feel ‘diabetes distress’ and emotional burden, so they may want some mental health support,” Dr. Amirtham notes. Managing a chronic condition affects emotional well-being, and addressing mental health is part of comprehensive diabetes care.
When medications are needed
If lifestyle modifications aren’t sufficient, medications become necessary. A variety of medications are available to help manage blood glucose levels in diabetes. These may be used alone or in combination, depending on individual needs and the type of diabetes, such as insulin, SGLT2 inhibitors, DPP-4 inhibitors, and sulfonylureas. Additional medications—such as metformin, thiazolidinediones, meglitinides, and alpha-glucosidase inhibitors—may also be used, depending on individual needs and clinical circumstances.
GLP-1 medications have become a major treatment option for Type 2 diabetes. These injectable medications help regulate blood sugar, promote weight loss, and offer cardiovascular benefits.
Treatment goals
“Optimal diabetes therapy provides more than glucose reduction,” Dr. Amirtham emphasizes. The goals of diabetes treatment include:
- Eliminating symptoms related to hyperglycemia (high blood sugar)
- Reducing cardiovascular complications
- Allowing the patient to achieve as normal a lifestyle as possible
Managing diabetes successfully means looking beyond blood sugar numbers to address the whole person and their quality of life.
What are the serious complications of diabetes?
Understanding potential complications underscores why diabetes management matters so critically.
“Diabetes is the leading cause for end-stage renal disease, non-traumatic lower limb amputations, and adult blindness,” warns Dr. Amirtham. “Additionally, patients with diabetes are at increased risk for cardiovascular disease, the main cause of morbidity and mortality.”
These complications develop when elevated blood sugar damages blood vessels and nerves over time:
- Kidney disease (nephropathy): Damaged blood vessels in the kidneys can lead to kidney failure requiring dialysis or transplant.
- Eye problems (retinopathy): Diabetes damages blood vessels in the retina, potentially causing vision loss or blindness.
- Nerve damage (neuropathy): High blood sugar injures nerves throughout the body, commonly causing numbness, tingling, or pain in the feet and hands.
- Foot complications: Nerve damage combined with poor circulation can lead to serious infections and, in severe cases, amputation.
- Cardiovascular disease: Diabetes significantly increases the risk of heart attack, stroke, and other cardiovascular problems.
- Skin conditions: Bacterial and fungal infections are more common with diabetes.
