Anemia is a condition in which a person lacks enough healthy red blood cells to carry adequate oxygen to a person body's tissues. Having anemia, also referred to as low hemoglobin, can make a person feel tired and weak.

There are many forms of anemia, each with its own cause. Anemia can be temporary or long term and can range from mild to severe. In most cases, anemia has more than one cause. See A person doctor if A person suspect that A person have anemia. It can be a warning sign of serious illness.

Treatments for anemia, which depend on the cause, range from taking supplements to having medical procedures. A person might be able to prevent some types of anemia by eating a healthy, varied diet.

Anemia occurs when there aren’t enough healthy red blood cells to carry oxygen to a person body’s organs. As a result, it’s common to feel cold and symptoms of tiredness or weakness. There are many different types of anemia, but the most common type is iron-deficiency anemia. A person can begin to ease symptoms of this type of anemia by adding iron to a person diet. Anemia happens when a person doesn’t have enough red blood cells or person red blood cells don’t work as they should. A person red blood cells carry oxygen throughout a person body. Oxygen powers a person cells and gives person energy. Without healthy red blood cells that do their job, a person body doesn’t get the energy it needs to function. While some types of anemia are short-term and mild, others can last for a lifetime. Left untreated, anemia may be life-threatening. There are many anemia types, each causing red blood cell levels to drop.

Nutritional anemias

Pernicious anemia: Pernicious anemia, one of the causes of vitamin B12 deficiency, is an autoimmune condition that prevents A person body from absorbing vitamin B12.

Iron-deficiency anemia: As its name implies, iron-deficiency anemia happens when a person body doesn’t have enough iron to make hemoglobin. Hemoglobin is the substance in person red blood cells that enables them to carry oxygen throughout a person body.

Megaloblastic anemia: Megaloblastic anemia is a type of vitamin deficiency anemia that happens when A person don’t get enough vitamin B12 and/or vitamin B9 (folate).

Inherited anemias

Sickle cell anemia: Sickle cell anemia changes a person red blood cells’ shape, turning round flexible discs into stiff and sticky sickle cells that block blood flow.

Fanconi anemia: Fanconi anemia is a rare blood disorder. Anemia is one sign of Fanconi anemia.

Diamond-Blackfan anemia: This inherited disorder keeps a person bone marrow from making enough red blood cells.

Fatigue- feeling too tired to manage person activities is the most noticeable anemia symptom. Other symptoms may include:

•             Shortness of breath (dyspnea): This is the feeling a person can’t catch a person breath or take a deep breath.

•             Dizziness: This is feeling lightheaded or unsteady on person feet.

•             Pounding or “whooshing” sound in a person ear (pulsatile tinnitus): This is a swooshing sound in one of A person ears that may come and go.

•             Headache: Iron-deficiency anemia and anemias caused by low hemoglobin may cause headaches.

•             Pale or yellow skin: A person skin color may be paler than usual.

•             Chest pain: This may feel like something is pressing on or squeezing a person chest.
