anemia

Paleness reflects the lack of red blood cells.
You fix that by fixing the anemia.

You need to know the cause of the anemia - is it occult bleeding? injury? autoimmune where the body attacks and destroys the cells? lack of a nutrient in the diet which is essential for building functional red blood cells?

The cause determines the treatment. Occult bleeding may be associated with cancer or irritable bowel in the GI tract. Autoimmune causes may be treated with a steroid and/or chemo drugs. Nutritional deficiency is treated by adding the nutrient back to the diet, or injecting it, or ensuring it can be absorbed.

And is this for a person or a cat? In a cat, you would see pale gums, but your description suggests you are talking about a human..

 

I have Celiac and have had issues with Iron Deficiency Anemia. What type of Anemia are you dealing with and what is causing it? Once your red blood cells build back up, you will feel tons better and you won't have the paleness. The main thing is to know what is causing the Anemia, so hopefully you have seen a doctor.
