@shoch1957 Normal Hgb for males is between 13 and 15 deciliter (g/dL). If your levels hover between 9 and 10.5 that’s considered mild anemia and certainly enough of a change in the amount of red blood cells carrying oxygen around your body to make a difference. Your doctor may not think this change is enough to have you feeling the side effects such as getting winded under load, but those of us who have experienced it, beg to differ. It’s similar to hiking at high altitudes. From my own experience (as a female) that was enough for me to start feeling something was off!

Moderate anemia (8 to 10 g/dL will have more pronounce symptoms such as looking pale, headaches, fatigue, shortness of breath, and heart palpations.
There’s not much that can be done at this point. Blood transfusions help but are generally only given somewhere below 8.
Has your doctor discussed a treatment plan for your MDS?
