But before you pull out your credit card for a test that can easily cost thousands of dollars out of pocket it is worth taking a deep breath to look at what science actually says about these scans.

How to Self-Advocate at a Doctor Appointment (and a list of resources)

Kai Dallas MD July 2, 2026

Self-advocating for your health is hard. When a doctor has only fifteen minutes to see you, it is not always a lack of empathy on their part, but rather a structural constraint that forces them to sprint through a checklist. It is far from ideal, but unfortunately, the reality of a broken system. To make sure your concerns are heard and taken seriously, you have to approach your appointment with a strategy. Here are some practical tips to help navigate your next visit to the doctor’s office. (And a list of healthcare resources at the end!)

The Modern Woman’s Guide to Preventing Osteoporosis

Jackie Dallas MD June 29, 2026

Osteoporosis is often called a silent disease because you cannot feel your bones getting weaker. There are no early warning signs, no throbbing aches to tell you that your bone density is slipping away. For far too many women, the very first symptom is a fracture that happens from something as simple as a minor trip, a sudden twist or a clumsy bump into something solid. This is why preventing osteoporosis is so important, because by the time you realize it has happened, it may already be too late.

What is a Hernia?

Stephanie Joyce MD June 4, 2026

A hernia is a common surgical condition that occurs when an organ or fatty tissue squeezes through a weak spot or “hole” in the surrounding muscle or connective tissue, known as fascia. There are several different kinds of hernias and may happen for a variety of reasons. It’s true that hernias are often viewed through a male-centric lens due to the high prevalence of inguinal hernias in men. However, women are disproportionally affected by femoral hernias, and pregnancy is one of the most significant physiological stressors on the female abdominal wall, which can reveal umbilical hernias and other wall defects such as diastasis recti.
