Why do people develop anemia?

Answer:
Usually it is because they are bleeding from some source or another. It could be an ulcer, cancer, esophogeal erosion, too much blood loss with menstration etc.

They might not be getting enough iron from what they eat or they may be bleeding somewhere internally.

I think that this disease is inherited.

Not enough protein intake cause that. I do not eat meat and have to take iron supplements to stay healthy. Also, an infection could possibly cause it. One other thing might cause it. Drug use. That will screw up your whole system.

Many things cause anemia. There are different kinds of anemia and different people live with it and don't know until they are tested. I personally feel it is inherited in my family, but I can't prove that. Many times is is lack of proper diet and it can be lack of absorption in the digestive system. When taking vitamin B complex, be sure to take Vitamin C as well. It helps with absorption.

It comes from too little iron intake. Iron is most abundant in meat, so vegetarians often develop it. Also, while iron is found in other foods such as legumes, it is not as easily absorbed as those from animal sources.
When your iron is too low it is more difficult for your blood to get oxygen to the tissues in your body. This makes you lethargic.

It can be inherited, genetic, iron deficiency from not eating or absorbing nutrients right (such as part of the stomach removed or liver), ulcers and bleeding, intestinal bleeding from crohns disease; irritable bowel, etc, heavy menstrations, and it can also be from the effects systemwide of drugs or treatments such as chemo.

Lack of red blood cells which happen from lack of Iron %26 such nutrients.

I have pernacious anemia which is a vitamin B12 deficiency and make the absorbsion of iron nearly impossible. I have had it since I was 11 yrs old and I inherited it from my mother .
I take B12 dots and prenatal vitamins(not pregnant) and try to eat a balanced diet. I rest when I need to and avoid places that can are likely to be high in infectious germs because the anemia lowers the immune system
