When your body doesn't make enough red blood cells, cells that carry oxygen from your lungs to the rest of your body. Also known as low hemoglobin, it's one of the most common blood disorders worldwide. You might feel tired, dizzy, or short of breath—not because you're lazy, but because your tissues aren't getting what they need. Iron deficiency, the most frequent cause of anemia, happens when you don't get enough iron from food or lose too much through bleeding. This isn't just about being a vegetarian or having heavy periods—it's about how your body absorbs, stores, and uses iron over time.
Nutritional anemia, a broad category that includes low iron, vitamin B12, or folate, affects children and adults differently. In kids, it often shows up as poor growth, trouble focusing in school, or pica (craving ice or dirt). In adults, it might be mistaken for burnout or aging. But the fix isn't always a pill. Sometimes it's changing what you eat—like adding more lean meat, beans, or leafy greens—or fixing an underlying issue like stomach ulcers or celiac disease. Hemoglobin, the protein in red blood cells that binds oxygen drops when your body lacks the building blocks to make new cells fast enough. And if you're on long-term medications—like NSAIDs or acid blockers—that can silently bleed your gut or block nutrient absorption, you might not even realize why you're exhausted.
Anemia doesn't always come with a simple label. It can be caused by chronic illness, kidney disease, or even genetic conditions like sickle cell. But the posts below focus on what you can actually do: how to spot early signs, what foods help or hurt, why some supplements fail, and how common drugs like iron pills or B12 injections really work. You'll find real guidance on child nutrition, medication interactions, and when to push for more testing. No fluff. Just what works—and what doesn't—based on current practice and patient outcomes.
Anemia and pulmonary arterial hypertension worsen each other, reducing oxygen delivery and increasing heart strain. Treating anemia in PAH patients can improve survival and quality of life-but only with the right approach.
