In some cases, a procedure called bone marrow biopsy may be advised. This involves inserting a special needle through the skin of the buttocks into the back of the hipbone. The needle is pushed into the middle of the bone, which contains bone marrow. A sample of marrow is taken out with the needle. The sample is then sent to the lab for examination and other testing.
Severe anemia can make a person too weak to perform normal activities.
It can even cause heart attacks , other organ damage, and death. However, most long- term effects of anemia depend on the cause. For example, cases due to low levels of vitamins or minerals can often be treated. These cases may cause no long-term effects. On the other hand, cases due to cancer may result in death.
