Anemia is a disorder of the blood. It occurs when your body does not produce enough erythrocytes or red blood cells (RBCs). Without the erythrocytes oxygen can not be adequately delivered to the tissues and organs throughout the body. This will cause you to become weak and tired. A person may also experience headaches‚ skin pallor‚ and faintness. Your body may attempt to compensate for these symptoms by speeding up the heart rate and respiratory rate. This is the body’s attempt to return oxygen

Pernicious Anemia and its association to orthostatic hypertension Pernicious anemia is the major form of vitamin B12 deficiency. It is caused by serum antibodies against intrinsic factor which leads to B12 deficiency rather than by B12 deficiency itself. Absorption of vitamin B12 requires intrinsic factor which is secreted by parietal cells. Pernicious anemia is marked by autoimmune attack on gastric mucosa and a loss in parietal cells. Approximately 75% of the affected patients have type I antibody

it means that their body does not produce and have enough healthy red blood cells‚ which then results in the lack of oxygen provided to body tissues. Pernicious anemia occurs when the intestines cannot absorb the vitamin B12‚ resulting in a decrease of red blood cells.

Megaloblastic anemias Definition: groups of anemias characterized by macrocytosis (in the peripheral blood) and megaloblastic changes in the bone marrow. The megaloblasts are large blasts – bone marrow. In periphery= macrocytosis= macrocytic anemia Cause: IMPAIRED DNA SYNTHESIS due to folate/ B12 deficiency Vitamin B12 is involved in the synthesis of methionine from homocysteine;methionine is necessary for the synthesis of myeline; B12 deficiency will explain the neurological manifestation

Anemia: People with anemia have a low number of red blood cells. Mild anemia often causes no symptoms. More severe anemia can cause fatigue‚ pale skin‚ and shortness of breath with exertion. Polycythemia vera: The body produces too many blood cells‚ from an unknown cause. The excess red blood cells usually create no problems but may cause blood clots in some people.
