Talking Points

Recent interactions between the hosts and their guests.

60: Celiac Disease — Symptoms You Could Be Missing, IBS Link & More With Selena Devries RD
Q: What is celiac disease and how does it differ from non-Celiac gluten sensitivity?
Celiac disease is an autoimmune condition that damages the small intestine's villi when gluten is consumed, leading to nutrient malabsorption and systemic symptoms; non-Celiac gluten sensitivity can cause similar discomfort without the intestinal damage, so the underlying pathology and long-term risks differ.
14: Training With Pelvic Floor Dysfunction – How to Build a Safe, Effective Plan
Q: When should people seek professional help rather than DIY?
If symptoms persist or impact daily life, it's worth booking a professional to prevent worsening conditions; a clarity call can help determine the right approach and avoid doing things that may worsen the issue.
14: Training With Pelvic Floor Dysfunction – How to Build a Safe, Effective Plan
Q: How should someone start addressing pelvic floor issues in a safe, progressive way?
Begin with nervous-system regulation and diaphragmatic breathing to relax the pelvic floor, then do rehab-style programming that targets the muscles around the pelvis, gradually progressing to integrated movement and strengthening within functional tasks like squats and lunges.
14: Training With Pelvic Floor Dysfunction – How to Build a Safe, Effective Plan
Q: What does a pelvic floor actually do and what are the common signs of dysfunction?
The pelvic floor holds in urine and stool, provides pelvic and spinal stability, and is involved in sexual function. Dysfunction can show up as leaking, difficulty fully emptying the bladder or bowels, pelvic or hip pain, back pain, and even intimacy issues.
13: Digestive Distress and Period Pain: The IBS–Endometriosis Link Explained
Q: Can you explain simply what endometriosis is and why it overlaps with IBS?
Endometriosis is a chronic inflammatory condition where endometrial-like tissue grows outside the uterus, causing pain and systemic immune activation. Because it can affect the gut and interact with the gut-brain axis, many people experience digestive symptoms that resemble IBS, leading to diagnostic confusion and a need for integrated management.
