What Actually Happens To Your Eyes When You Look At The Sun?

Jackie Dallas MD August 11, 2026

With all the excitement surrounding the upcoming total solar eclipse, let’s talk about why it is important to know how to enjoy it safely, and why you should never stare at the sun.

We knew it was bad and could hurt your eyes, but few people ever explain the actual biology of what actually happens and how it affects your vision when you sneak a glance at a bright sky.

Pulmonary Arterial Hypertension

Jackie Dallas MD August 9, 2026

Pulmonary arterial hypertension, often shortened to PAH, is a complex, and progressive condition that affects the tiny blood vessels in your lungs causing them to narrow and thicken. PAH causes elevated pressure within the pulmonary arteries, the blood vessels that carry oxygen-depleted blood from your heart to your lungs to pick up fresh oxygen, which can lead to heart failure if left untreated. PAH is considered a rare disease, affecting roughly only 15 to 50 people per million worldwide. However, it predominantly affects women, being two to four times more common than in men.

The gallbladder is a small, pear-shaped, sac-like organ located beneath the liver that plays a critical role in the digestive process by storing and concentrating bile. While seemingly minor, gallbladder dysfunction is one of the most common reasons for emergency surgical consultation, and women are twice as likely to develop issue. When the chemical balance of bile is disrupted, it forms precipitates known as gallstones, which can lead to inflammation, infection, or structural blockage.

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.
