- Broadcast from KSQD, Santa Cruz on 4-02-2026: Dr. Dawn briefly responds to an emailer in Aptos, advising that her numbers don't require rushing into therapy but recommending a more thorough workup. An emailer asks about her sister's osteoporosis treatment, including Reclast side effects and vitamin D levels of 28. Dr. Dawn recommends raising vitamin D to around 50, adding vitamin K2 (MK7-9) and calcium, and suggests weekly oral Fosamax as an alternative to annual Reclast infusions that cause week-long flu-like symptoms. A caller reports dizziness when sitting up in bed and recent fainting episodes during hot weather. Dr. Dawn distinguishes vestibular problems from postural hypotension — spinning dizziness when legs are still in bed suggests loose otoliths in the semicircular canals rather than blood pressure issues. She recommends the Dr. Foster vestibular exercises and increased fluid and salt intake. Cancer survival has reached a major milestone: 70% of U.S. patients now survive at least five years, up from 50% in the 1970s, thanks to reduced smoking and advances like immunotherapy and checkpoint inhibitors. An Estonian Biobank study of 67,000 adults found men's libido peaks in their early 40s while women's peaks in their 20s-30s with sharper decline around age 50, though testosterone levels begin falling in men's early 30s. Dr. Dawn frames perimenopause and menopause as natural transitions rather than diseases, explaining that perimenopausal hormone swings can actually be larger and more erratic than during fertile years. She recommends limiting caffeine (which is metabolized more slowly after menopause), alcohol, and spicy foods, and strongly advocates transdermal bioidentical hormones over oral synthetics—oral estrogen increases clotting risk 400% while transdermal carries no increased risk. An emailer asks about transcranial magnetic stimulation for depression. Dr. Dawn explains that while the technology works and shows benefit in studies, targeting remains challenging because each person's brain architecture differs based on individual developmental experiences. Researchers found that applying gamma-frequency electrical stimulation (40-90 Hz) to frontal and parietal lobes made participants more likely to choose generous money-splitting options with strangers, suggesting brain stimulation can nudge social decision-making toward altruism. A small Indian study found that daily conch shell blowing reduced sleep apnea symptoms by 34% after six months, similar to earlier didgeridoo research—blowing against resistance strengthens airway muscles and increases resting muscle tone during sleep.
