Systemic Mycoses: What They Are, How They Spread, and What Treatments Work
When a fungal infection goes deep into your body—beyond the skin or nails—it becomes a systemic mycoses, serious fungal infections that spread through the bloodstream to internal organs. Also known as deep fungal infections, these aren’t your typical athlete’s foot or yeast infection. They can attack your lungs, brain, heart, or kidneys, and often hit people with weakened immune systems hardest.
Common types include candidiasis, a fungal infection caused by Candida species that can spread from the mouth or gut into the blood, and aspergillosis, a mold infection that starts in the lungs and can spread to other organs. Others like histoplasmosis, blastomycosis, and cryptococcosis are tied to specific environments—bird droppings, soil near rivers, or bat caves. You don’t catch them from other people. You breathe them in or swallow them, and if your body can’t fight back, they take root.
People on long-term antibiotics, chemotherapy, or corticosteroids are at higher risk. So are those with HIV, diabetes, or organ transplants. The symptoms? Often vague—fever, fatigue, cough, weight loss—so they’re easily missed or mistaken for the flu or pneumonia. That’s why diagnosis usually needs blood tests, imaging, or tissue samples. Treatment isn’t simple either. Unlike bacterial infections, you can’t just take an over-the-counter pill. Systemic mycoses require strong antifungal drugs like amphotericin B, fluconazole, or voriconazole, often given for weeks or months. And even then, relapses happen.
What you’ll find in the posts below isn’t just a list of drugs. It’s real-world insight into how these infections interact with other medications, how treatments affect liver function, what side effects patients actually face, and how some supplements might help—or hurt—recovery. You’ll see how antifungals overlap with drugs for epilepsy, diabetes, and heart conditions. You’ll learn what works, what doesn’t, and why some patients need more than just pills to get better.
