Uric Acid: Antioxidant Versus Pro-oxidant in Glaucoma Introduction: Glaucoma is a progressive optic nerve disease in which oxidative stress and vascular dysfunction are thought to contribute to retinal ganglion cell loss. Uric acid (UA), the end product of purine metabolism, is of growing interest because it circulates at high levels in humans and has complex redox effects. In blood, UA is a poten...
Uric acid is a natural chemical that your body makes when it breaks down substances called purines, which come from the food you eat and the cells in your body. It normally dissolves in the blood, passes through the kidneys, and leaves the body in urine. Most people have a balance where production and excretion match, but when uric acid builds up it can form sharp crystals that cause pain in joints or form stones in the urinary tract. Doctors often measure uric acid levels with a simple blood or urine test to check for these problems. Uric acid also has a surprising role as a defender against certain types of chemical damage in the body, but that benefit can be outweighed when levels get too high. Because of this dual nature, both low and high levels may be linked to different health issues. What you eat, how much you weigh, certain medications, and how well your kidneys work all affect uric acid levels. Treating high uric acid usually involves diet changes, medication, and managing other conditions like high blood pressure or diabetes. Paying attention to uric acid matters because it connects to common and painful conditions like gout and kidney stones, and it can signal other health risks.
