The Hormone Cafe

In this episode of The Hormone Café, Dr. Sarah Pederson explains why the uterine lining (endometrium) is one of the most important—and most overlooked—parts of fertility and women’s health. She breaks down how a healthy lining forms each month, what symptoms signal a problem, how we evaluate it, and the treatments that can restore implantation and reduce miscarriage risk.

Your uterine lining isn’t just about your period—it’s the foundation for pregnancy.

In This Episode, You’ll Learn:

🌸 What the Uterine Lining Is & Why It Matters
The uterine lining (endometrium) grows each month under estrogen, stabilizes with progesterone after ovulation, and sheds during your period.

A healthy lining is essential for:

• Implantation
• Placental development
• Preventing miscarriage
• Normal menstrual cycles

If the lining is too thin, too thick, inflamed, or scarred, fertility can be affected.

🚩 Red Flags for an Unhealthy Uterine Lining
Symptoms that may signal a lining problem include:

• Very light periods
• Very heavy bleeding or large clots
• Spotting before periods
• Mid-cycle bleeding
• Recurrent miscarriages
• Unexplained infertility
• History of IUDs, D&C, or uterine procedures

These signs often point to instability, inflammation, infection, or scar tissue.

🔬 How We Evaluate the Uterine Lining
Dr. Sarah explains a full diagnostic approach:

• Hormone testing before and after ovulation
• Ultrasound to measure lining thickness
• Blood flow evaluation
• Endometrial biopsy to check cell health
• Testing for chronic infection or inflammation
• Hysteroscopy to visually inspect the uterus

A healthy lining is typically 6–10 mm near ovulation with good blood flow.

🧬 Common Uterine Lining Diagnoses
Some causes of abnormal lining include:

• Thin lining
• Chronic endometritis (infection/inflammation)
• Scar tissue
• Polyps
• Fibroids
• Hormone imbalance
• Poor blood flow

These are treatable once identified.

💊 Treatment Options to Restore Lining Health
Treatment is individualized and may include:

• Antibiotics for infection
• Hysteroscopy to remove scar tissue or polyps
• PRP intrauterine therapy
• Estrogen therapy (oral or vaginal)
• Vaginal sildenafil (Viagra) for blood flow
• L-arginine and vitamin E
• Baby aspirin or pentoxifylline
• Nutritional therapy and targeted IV nutrients

The goal is to rebuild a strong, receptive lining.

🌿 Lifestyle & Nutrition Support
Healing also depends on whole-body health:

• Anti-inflammatory nutrition
• Adequate vitamins and antioxidants
• Regular cardio to improve uterine blood flow
• Stress management
• Proper hormone balance

Fertility is never just one organ—it’s the whole system.

Key Takeaways:

• The uterine lining is essential for implantation and pregnancy
• Light or heavy periods can signal lining issues
• Hormone testing + ultrasound + biopsy give answers
• Infection, scar tissue, and poor blood flow are treatable
• Nutrition, supplements, and movement support healing
• Evaluating the lining can unlock unexplained infertility
