Does TRT affect eyesight?

Polycythemia is a condition characterized by an increased number of red blood cells in the bloodstream. A recent study titled “Neuro-Ophthalmic Presentations of Polycythemia,” published in the Journal of Neuro-Ophthalmology, explores how this condition can affect the eyes and vision. The research indicates that individuals with polycythemia may experience various eye-related symptoms, such as vision changes, headaches, or even vision loss. These symptoms arise because the excessive red blood cells can thicken the blood, leading to reduced blood flow to the eyes and optic nerve. The study emphasizes the importance of recognizing these visual symptoms early, as they can be the first indicators of polycythemia. Timely detection and treatment are crucial to prevent potential complications and preserve eye health.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
