World Osteoporosis Day is October 20: Here’s How to Strengthen Your Bones at Every Age
Posted on by Leslie Branon

Annually on October 20, World Osteoporosis Day reminds us that strong bones are the foundation of lifelong health. Osteoporosis, a condition that weakens bones and increases the risk of fractures, affects both men and women, though it’s often thought of as primarily a women’s health issue. In reality, while women are more likely to develop osteoporosis (with universal screening recommended after age 65), about one in five men over 50 will also experience an osteoporotic fracture in their remaining years. In fact, men account for roughly one in four hip fractures among older adults.

The good news? Prevention and early treatment can make a difference. Simple daily habits play a major role in protecting bone health, and our experts emphasize one in particular: quitting smoking. Below, we’ll explain why breaking this habit can prevent osteoporosis, along with other tips for keeping your bones strong.

Why Bone Health Matters

Bone density naturally decreases over time, and hormonal changes, diabetes, and certain medications can accelerate bone loss. Without proper screening and management, this can lead to fractures of the hip, wrist, or spine injuries that drastically impact quality of life.

How Smoking Weakens Your Bones

Cigarette smoke in particular affects nearly every organ system, including the skeletal system. Smoking undermines bone health by:

  • Reduced blood supply: Smoking can constrict blood vessels and reduce blood flow to bones, impairing nutrient delivery and healing.
  • Hormonal interference: Tobacco disrupts levels of estrogen and testosterone, both of which play roles in bone maintenance.
  • Lower calcium absorption: Smoking has been linked to decreased calcium uptake in the intestines, making it harder for bones to build or maintain density.
  • Impaired bone-forming cells: Some evidence suggests toxins in smoke may negatively affect osteoblasts (the cells that build bone).

Because of these effects, smokers tend to lose bone more rapidly, heal more slowly from fractures, and endure higher fracture risk. Quitting smoking can slow bone loss and improve recovery outcomes.

Expert Tips to Build Bone Strength 

Strategies you can adopt now include:

  1. Nutrition:
    • Aim for adequate calcium (1,000–1,200 mg daily, depending on age/gender)
    • Pair with vitamin D (to improve absorption)
    • Include protein, magnesium, and phosphorus
  2. Move your bones:
    • Weight-bearing exercises (walking, jogging, dancing)
    • Resistance training (bodyweight, light weights, bands)
    • Balance and posture work to reduce fall risk
  3. Limit bone-harmful habits:
    • Quit smoking
    • Keep alcohol use moderate
    • Avoid excessive caffeine or soda
  4. Screen and monitor:
    • Bone density scans (DEXA) as recommended
    • Discuss bone health with your endocrinologist or primary care provider

Latest Breakthroughs: Reversing Bone Loss via GPR133

In promising news, a receptor called GPR133 (also known as ADGRD1) has recently been identified as a primary regulator of bone density. A study published by ScienceAlert describes how stimulating this receptor with a chemical compound (named AP503) in animal models significantly increased bone strength, even in bones with osteoporosis-like damage. 

When GPR133 was activated, osteoblasts (cells that build bone) became more active, producing stronger bone tissue. The effect was even more pronounced when used in combination with exercise, providing a synergistic approach to bone health. 

While this research is still in early stages and conducted in animal models, it opens up promising avenues: in the future, therapies targeting GPR133 might not just slow bone loss, but reverse it, rebuilding degraded bone to healthier strength.

10 Signs of Thyroid Disease You Need to Know
Posted on by Leslie Branon

Thyroid disease can be difficult to recognize because its symptoms are often vague and easily mistaken for everyday stress, aging, or other health issues. Fatigue, weight changes, or mood shifts may not seem connected at first, but together they can point to a thyroid problem. 

At Texas Diabetes & Endocrinology, our team specializes in identifying and treating thyroid disease, helping patients find answers and get the care they need to feel their best.

What Is Thyroid Disease and How Does It Affect Your Body?

Your thyroid is a butterfly-shaped gland located in the front of your neck. It produces hormones (primarily T3 and T4) that regulate metabolism, body temperature, heart rate, and more. Thyroid disease occurs when your thyroid works too hard (hyperthyroidism) or not enough (hypothyroidism), or if its structure becomes abnormal (nodules, goiters, thyroiditis). 

Over time, untreated thyroid issues can lead to heart problems, cholesterol changes, fertility issues, and reduced quality of life.

10 Symptoms of Thyroid Problems

Here are 10 signs that could indicate thyroid disease. One symptom alone doesn’t mean there’s a problem, but if you spot several, it’s worth getting checked.

  1. Fatigue, low energy, or feeling sluggish – Even after a full night’s sleep, you still feel tired or drained.
  2. Weight changes – Unexplained weight gain (common in hypothyroidism) or weight loss despite unchanged eating and exercise (seen in hyperthyroidism).
  3. Temperature sensitivity – Feeling excessively cold when others are comfortable (hypothyroidism) or overly hot/sweaty (hyperthyroidism).
  4. Digestive disturbances – Constipation when thyroid is underactive; frequent bowel movements or diarrhea if overactive.
  5. Dry skin, hair loss, brittle nails – Hair thinning, dry or coarse skin, nails that break easily or grow more slowly.
  6. Memory, focus & “brain fog” – Trouble concentrating, forgetfulness, or difficulty in mental tasks.
  7. Mood swings, anxiety, or depression – Mood changes that do not match situational stress—feeling anxious, irritable, depressed.
  8. Irregular heartbeat or palpitations – Heart racing, fluttering, or skipped beats.
  9. Swelling in neck / Lump or goiter – Visible swelling in front of the throat, difficulty breathing or swallowing, voice changes.
  10. Swelling / puffiness in face or hands – Feeling bloated, facial puffiness or swelling not due to diet or other obvious causes.

Who Is at Risk for Thyroid Disease?

Certain factors increase your risk of thyroid problems:

  • Family history of thyroid disease
  • Autoimmune disorders (Type 1 diabetes, lupus, rheumatoid arthritis)
  • Prior radiation therapy to neck or chest
  • Gender & age (women, especially middle-age or older, are more likely)
  • Pregnancy or postpartum period
  • Iodine deficiency (rare in U.S., more common in certain diets)

What To Do If You Notice Symptoms of Thyroid Problems

If you recognize several of these signs, our thyroid specialists recommend you schedule a visit with your primary care provider and share all of your symptoms, even the ones that seem minor. Your doctor may order lab work to understand how your thyroid is functioning and perform a physical exam to check for swelling, nodules, or other changes in the thyroid gland. 

In many cases, your provider may recommend that you see an endocrinologist for further evaluation and treatment. Depending on your results, management might include thyroid hormone replacement for an underactive thyroid, medication to reduce hormone levels for an overactive thyroid, or, in some cases, surgery. 

Alongside medical treatment, healthy lifestyle habits—such as balanced nutrition, stress management, and good sleep—can also play an important role in supporting thyroid health.

A Closer Look at Liquid Sugar and Diabetes 
Posted on by Leslie Branon

Recent research has shed new light on the risks associated with sugary beverages. A study from Brigham Young University (BYU) has revealed that consuming sugar in liquid form—such as in sodas, sweetened teas, and fruit juices—may increase the risk of developing type 2 diabetes more significantly than consuming sugar in solid foods.

What Is Liquid Sugar?

Liquid sugar refers to added sugars found in beverages, including sodas, sweetened teas, energy drinks, and fruit juices. Unlike sugars found in whole fruits, which are accompanied by fiber and nutrients, liquid sugars are absorbed quickly into the bloodstream. This rapid absorption can lead to spikes in blood sugar and insulin levels, placing added stress on the body over time.

Understanding Type 2 Diabetes

Type 2 diabetes occurs when your body doesn’t respond normally to insulin. Over time, insulin resistance causes your body to require even more insulin, resulting in high blood sugar and increasing the risk of complications such as heart disease, kidney damage, and nerve problems. Factors contributing to type 2 diabetes include genetics, lifestyle choices, and dietary habits.

The Link Between Liquid Sugar and Health Risks

The BYU study found that each 12-ounce serving of sugar-sweetened beverages consumed daily was associated with a 25% increased risk of developing type 2 diabetes. This heightened risk is thought to be due to the rapid absorption of liquid sugars, which can lead to increased fat storage, insulin resistance, and inflammation.

Excessive consumption of sugary drinks has also been linked to heart disease. High sugar intake can lead to obesity, high blood pressure, and elevated triglyceride levels—all risk factors for cardiovascular disease.

Reducing the intake of sugary beverages is a proactive step toward better health. Consider the following tips:

  • Choose Water or Unsweetened Beverages: Opt for water, herbal teas, or beverages without added sugars.
  • Read Labels Carefully: Be aware of hidden sugars in drinks labeled as “natural” or “healthy.”
  • Gradual Reduction: If you’re accustomed to sugary drinks, try gradually reducing your intake to allow your taste buds to adjust.

Reduce Your Type 2 Diabetes Risk

Additional steps you can take to protect your health and prevent type 2 diabetes include:

  • Maintain a Healthy Weight: Even modest weight loss can improve insulin sensitivity.
  • Stay Active: Aim for at least 150 minutes of moderate physical activity per week, such as brisk walking, swimming, or cycling.
  • Choose Whole Foods: Emphasize vegetables, fruits, whole grains, lean proteins, and healthy fats.
  • Limit Processed Foods: Reduce consumption of refined carbohydrates and foods high in added sugars.
  • Monitor Blood Sugar: Regular screenings can help detect early changes and allow for timely lifestyle adjustments.
  • Prioritize Sleep: Poor sleep can affect metabolism and insulin resistance. Aim for 7–9 hours of quality sleep per night.

Wearable Devices and Your Health: Insights from Dr. Lucy Esteve
Posted on by Leslie Branon

Wearable technology is becoming an increasingly popular way to monitor health — and for good reason. These devices offer valuable information that can help you better understand your body and make changes to support your overall health. 

We asked endocrinologist Dr. Lucy Esteve to share everything you need to know about using wearable devices to help achieve your metabolic health goals. 

Why are wearables important in the fight against diabetes?

Over one-third of the U.S. population has prediabetes, and 9 out of 10 people remain undiagnosed. That’s why there’s a pressing need for more widespread screening in the community to help prevent progression to diabetes and the complications that come with it. Wearable devices give us an opportunity to engage patients in their own health and help them make informed changes.

What types of wearable devices are available, and what do they track?

Wearables are non-invasive biometric sensors worn on the body and used worldwide for personalized health monitoring. Think of devices like the Apple Watch, Fitbit, Garmin, and Oura Ring. They generate objective data such as step count, calories burned, sleep patterns, and physiological stress. That immediate feedback can be leveraged to improve glycemic control, encourage self-care, and boost self-efficacy.

Can wearables measure blood sugar?

It’s important to know that, as of yet, smartwatches in the U.S. are not FDA-approved for detecting glycemic dysfunction and don’t provide reliable, real-time glucose levels. However, continuous glucose monitors (CGMs) are minimally invasive wearables that are FDA-approved for managing diabetes and they’ve truly revolutionized how we detect and address blood sugar issues.

What’s new in CGM technology?

We now have over-the-counter CGMs like Abbott’s Lingo and Dexcom’s Stelo. These are designed for people who want to track their metabolic health even without a diabetes diagnosis and do not require a prescription. They allow users to monitor trends in blood glucose rather than single data points like a lab draw, and data can even be shared with healthcare professionals via apps like Dexcom Clarity.

Are there limitations to these devices?

OTC CGMs can be costly, and they only measure glucose levels (they don’t provide additional biometric data). They also don’t have high or low glucose alerts, and accuracy can vary within an acceptable range. Finally, not all of them are integrated into electronic health record systems, which can make clinical workflow more challenging.”

Can you share an example of when CGM technology made a difference for a patient?

A patient in her 40s came to see me for evaluation of intermittent episodes of anxiety, shakiness, palpitations, dizziness, fatigue, and weight gain despite a healthy lifestyle. Her extensive cardiac work-up (EKG, stress testing and echocardiogram) and psychiatric evaluation (for anxiety disorder) were normal, and even her fingerstick glucose checks looked fine. We decided to try a CGM for two weeks, and she carefully logged her meals, symptoms, and exercise. When we reviewed the data together, we found she was having rapid blood sugar spikes after higher-carb meals, followed by quick drops — typical of reactive hypoglycemia. By simply adjusting her diet and adding more frequent high-protein snacks every 2–3 hours, her symptoms improved dramatically.

The Bottom Line

Wearable devices are powerful tools that can help patients and healthcare providers work together toward better health outcomes. As Dr. Esteve explains, they are not a replacement for medical evaluation, but when used correctly, they can be a game-changer in understanding and managing your health.
