Type 2 Diabetes:What You Should Know
Type 2 diabetes is the most common form of diabetes, developing when the body gradually stops responding to insulin — a state called insulin resistance. To compensate, the pancreas works harder to move glucose from the bloodstream into your cells for energy, until it can no longer keep up and blood sugar begins to rise.
Because Type 2 diabetes usually progresses slowly, many people live with elevated blood sugar (hyperglycemia) for years before noticing it. Left unmanaged, it can strain the heart, kidneys, eyes, nerves, and blood vessels over time. The encouraging part: with early, structured care, Type 2 diabetes is highly manageable and, for some patients, remission is possible. At EndoInnova in Hatillo, board-certified endocrinologist Dr. Sheila S. Mercado Méndez guides patients across Puerto Rico’s North Coast with personalized, evidence-based treatment.
Common Symptoms
To Watch For
Type 2 diabetes symptoms tend to appear gradually and can be easy to dismiss. Recognizing these early signs means Dr. Mercado Méndez can begin evaluation and treatment sooner.
- Increased thirst
- Frequent urination
- Increased hunger
- Unexplained weight loss
- Fatigue or low energy
- Blurred vision
- Slow-healing cuts or wounds
- Frequent infections
How Is Type 2 DiabetesDiagnosed?
Because Type 2 diabetes develops gradually, it’s often confirmed with simple blood tests before symptoms become obvious — sometimes during a routine check-up. These tests measure your blood sugar and how well your body processes glucose. At EndoInnova in Hatillo, Dr. Sheila S. Mercado Méndez uses the results to confirm the diagnosis, gauge its severity, and shape a treatment plan built around you.
| Test | Normal / Typical Range | Indicates Diabetes | What It Shows |
|---|---|---|---|
|
HbA1c |
< 5.7% |
≥ 6.5% |
Average blood sugar levels over the past 2–3 months |
|
Fasting Blood Glucose |
< 100 mg/dL |
≥ 126 mg/dL |
Blood sugar level after at least 8 hours of fasting |
|
Oral Glucose Tolerance Test (OGTT) |
< 140 mg/dL (2-hour value) |
≥ 200 mg/dL (2-hour value) |
How effectively the body processes glucose after consuming a glucose drink |
|
Random Blood Glucose |
Varies |
≥ 200 mg/dL (with classic diabetes symptoms) |
Blood sugar level measured at any time of day to support diagnosis |
Managing Type 2 Diabetes:Core Treatment Approach
Type 2 diabetes treatment usually follows a stepwise approach: it often begins with lifestyle changes, then adds medication and, when needed, insulin as the condition evolves. The goals are to control blood sugar, improve insulin sensitivity, and lower the risk of long-term complications. At EndoInnova in Hatillo, Dr. Sheila S. Mercado Méndez tailors each plan to the patient’s health, lifestyle, and blood sugar targets.
A balanced, nutrient-rich diet with controlled portions and carbohydrates helps regulate blood sugar levels and supports overall metabolic health.
Oral medications and, when appropriate, injectable therapies help improve insulin function, reduce glucose production, or increase glucose elimination for better blood sugar control.
Regular monitoring of blood sugar levels helps evaluate treatment effectiveness, guides medication adjustments, and supports day-to-day diabetes management.
Reaching and maintaining a healthy weight can significantly improve insulin resistance and, for some patients, may support Type 2 diabetes remission.
Some patients with Type 2 diabetes may need insulin if lifestyle changes and medications are no longer enough to maintain healthy blood sugar levels.
Advanced Technology
In Type 2 Diabetes Care
You don’t have to manage Type 2 diabetes on guesswork anymore. Today’s diabetes technology gives patients a clearer, real-time view of their blood sugar — making daily management simpler and helping prevent long-term complications. Not everyone needs these tools, but for the right patient they’re a game-changer. Dr. Sheila S. Mercado Méndez recommends the technology that fits each patient’s needs and goals.
Continuous Glucose Monitoring (CGM)
Insulin Pumps & Closed-Loop Systems
Protecting Your Future Health
in Type 2 Diabetes
The complications of Type 2 diabetes rarely announce themselves. Over time, blood sugar that stays too high can quietly damage the blood vessels and nerves that keep your heart, kidneys, eyes, and feet healthy — often before you feel a thing. The risk climbs when blood sugar, blood pressure, and cholesterol drift out of range together, which is why Type 2 diabetes is best managed as a whole-body condition.
The good news: most of these complications are preventable or can be delayed with early, consistent care. Regular screenings catch small changes long before they become serious problems. At EndoInnova in Hatillo, Dr. Sheila S. Mercado Méndez provides structured monitoring for patients across Puerto Rico’s North Coast — so your kidneys, eyes, nerves, and heart are checked and protected year after year.

Frequently Asked
Questions
We have answered some common questions to help you better understand our comprehensive approach to diabetes care, glucose monitoring, and long-term metabolic health.
What causes Type 2 diabetes?
Type 2 diabetes develops when your body becomes resistant to insulin and the pancreas can’t produce enough to keep blood sugar in a healthy range. Common contributors include genetics, excess weight, physical inactivity, aging, and certain medical conditions. An endocrinologist can pinpoint the factors most relevant to you.
Can Type 2 diabetes be prevented?
In many cases, yes. Maintaining a healthy weight, eating a balanced diet, staying active, avoiding tobacco, and managing blood pressure and cholesterol can significantly lower your risk. If you have prediabetes, an early evaluation with Dr. Mercado Méndez can help prevent or delay Type 2 diabetes.
How is Type 2 diabetes treated?
Treatment usually follows a stepwise approach: healthy eating, activity, and weight management first, then medications, and insulin only if needed. Options range from oral pills to injectable therapies like GLP-1 receptor agonists. At EndoInnova, every plan is personalized to your blood sugar goals and lifestyle.
What is the difference between Type 1 and Type 2 diabetes?
Type 1 diabetes is autoimmune — the immune system destroys insulin-producing cells, so lifelong insulin is required. Type 2 diabetes is driven by insulin resistance and is far more common in adults, though it can occur at any age. It’s often managed with lifestyle, medication, and sometimes insulin.
Can Type 2 diabetes be reversed or go into remission?
For some patients, yes — Type 2 diabetes can enter remission, meaning blood sugar returns to a healthy range without medication. This is most achievable through significant weight loss and lifestyle change, especially early on. Remission isn’t guaranteed and requires ongoing monitoring, which Dr. Mercado Méndez provides.
What HbA1c level is good for Type 2 diabetes?
For most adults with Type 2 diabetes, an HbA1c below 7% is a common target, though the right goal depends on your age, health, and other conditions. Below 5.7% is normal, and 5.7–6.4% suggests prediabetes. Your endocrinologist will set a target that’s safe and realistic for you.
What foods should I avoid with Type 2 diabetes?
There are no strictly forbidden foods, but it helps to limit sugary drinks, refined carbs, fried foods, and processed snacks that spike blood sugar. Focus on vegetables, lean protein, whole grains, and healthy fats. A personalized nutrition plan works better than any one-size-fits-all diet.
Is Type 2 diabetes hereditary?
Genetics play a real role — having a parent or sibling with Type 2 diabetes raises your risk. But genes aren’t destiny. Lifestyle factors like weight, diet, and activity strongly influence whether that risk becomes diabetes, which means prevention is often within your control.
What are GLP-1 medications, and are they right for me?
GLP-1 receptor agonists (such as semaglutide) are injectable medications that lower blood sugar, curb appetite, and often support weight loss. They’ve become central to modern Type 2 care, but they aren’t right for everyone. Dr. Mercado Méndez evaluates your health to determine if they fit your plan.
When should I see an endocrinologist for Type 2 diabetes?
Consider seeing an endocrinologist if your blood sugar is hard to control, your treatment plan needs adjusting, you’re starting insulin or a CGM, or you’re developing complications. EndoInnova provides specialist, endocrinology-led care for patients across Hatillo, Manatí, Arecibo, and Puerto Rico’s North Coast.
