If you're taking a GLP-1, headlines about sudden vision loss can leave you wondering whether the medication helping you lose weight is putting your eyesight at risk. Ana Reisdorf talks with Dr. Luke Sorrell about NAION, a rare optic nerve condition, and the semaglutide research behind those headlines. You'll learn how to put "double the risk" into perspective, what questions to bring to your doctor, and why your health history matters to the conversation.

**IN THIS EPISODE**

- What NAION is and how it can affect vision
- What semaglutide studies suggest, and the limits of observational research
- Why relative risk and absolute risk tell different parts of the story
- How diabetes, sleep apnea, cardiovascular health, and optic nerve anatomy fit into the discussion
- Blood pressure changes, dehydration, and rapid blood sugar changes as possible contributing factors
- Questions to ask your prescriber and eye care professional about your individual risk
- What remains uncertain about tirzepatide and other GLP-1 medications
- Weighing potential eye risks alongside the benefits of GLP-1 treatment

How are GLP-1 type medications and weight control changing the landscape of heart health? If you're using a GLP-1 for weight or blood sugar, which habits and risk factors still deserve attention? Ana Reisdorf talks with Dr. Melanie Icard about stress, sleep, muscle, food choices, and questions to bring to your healthcare team when heart disease runs in the family.

Dr. Icard shares how her experience with prediabetes shaped her practice and why she asks patients, "What are you doing to relax?" Ana brings the GLP-1 user's perspective: how to eat well with a smaller appetite and make strength work realistic when life is already full. They also discuss what Ana's family history has prompted her to ask about lab markers and heart imaging.

**IN THIS EPISODE**

- Why stress and sleep belong in a conversation about heart and metabolic health
- What it can look like to make room for real rest during a busy week
- How strength work and everyday movement fit into GLP-1 weight loss
- Choosing nourishing meals when your appetite is smaller
- Questions to ask your clinician about family history, lab markers, and heart imaging
- Building habits you can keep up as your health goals change

If you're taking a GLP-1, you've probably heard plenty about protein and strength training. Where does creatine fit, and what does it mean if the scale rises after you start taking it? Ana Reisdorf talks with Kristin Kirkpatrick about muscle health, the practical choices involved in taking creatine, and what the research can and cannot yet tell us about benefits beyond the gym.

Kristin explains how creatine works alongside resistance training, why a loading phase may not be necessary, and what to consider when choosing a form. She and Ana also discuss bloating, water retention, early research on brain health, and whether you can build muscle after starting a GLP-1.

**IN THIS EPISODE**

- What creatine does in the body and why it comes up in the muscle-health conversation
- How creatine, protein, and resistance training fit together during GLP-1 weight loss
- What emerging research suggests about brain health and what it does not establish
- Creatine monohydrate, HCl, powders, and gummies: questions to consider when choosing a product
- Loading phases, dose, and timing, and why individual needs vary
- Water retention, bloating, and why a change on the scale may not mean fat gain
- Building strength and muscle after starting a GLP-1

What can getting out of a chair tell you about your muscle health? Ana Reisdorf, Registered Dietitian and GLP-1 user, joins muscle and bone researcher Mark Hamrick to explore staying strong during GLP-1 weight loss, perimenopause, and menopause. You'll learn what three simple assessments can reveal about physical function, and why muscle size alone doesn't tell the whole story.

Mark explains the differences between muscle mass, quality, strength, and power, and how they connect to everyday movement and healthy aging. Ana shares her own assessment results and asks whether her regular exercise routine is enough. They also discuss bone density, fall risk, and finding an approach to exercise that works when pain or physical limitations get in the way.

**IN THIS EPISODE**

- Why losing muscle size doesn't necessarily mean losing the same amount of strength
- What chair rises, single-leg balance, and walking speed can tell you about physical function
- How menopause, sleep, and activity levels enter the muscle-health conversation
- Resistance training, protein, and the research Mark discusses on creatine
- Adapting exercise with help from a physical therapist when movement is painful
- Bone density, DEXA scans, fall risk, and questions to bring to your healthcare provider

**ABOUT THE GUEST**

Mark Hamrick is president and co-founder of Velogenix and a former Regents Professor at the Medical College of Georgia. His research on muscle and bone aging has received NIH funding over the last two decades. He has published more than 225 peer-reviewed papers and advised NASA on muscle and bone loss in space. At Velogenix, he is applying that experience to tools for quickly assessing muscle health at home.
