Pernicious Anemia
S a type of anemia that happens when stomach cells are not able to make intrinsic factor. Symptoms include:
Weakness
Pale skin
Diarrhea
Weight loss
Fever
Numbness or tingling sensation in the hands and feet
Loss of balance
Confusion, memory loss, and moodiness
Vitamin B12 supplements in high doses, either given as injections or orally, are prescribed to treat pernicious anemia. However, researchers do not know whether high homocysteine levels actually cause heart disease.
People who are concerned about heart disease should try to get enough B vitamins from healthy foods. However, in some cases doctors recommend taking B vitamins to lower homocysteine levels. Age-related macular degeneration (AMD)
One large study found that women who took 1,000 mcg of vitamin B12, along with 2500 mcg of folic acid and 500 mg of vitamin B6 daily, reduced the risk of developing AMD, an eye disease that can cause loss of vision.
Fatigue
Fatigue is one of the symptoms of a vitamin B12 deficiency. However, more research is needed. One preliminary study indicated that people with chronic fatigue syndrome might benefit from B12 injections.
More research is needed. Another preliminary study suggested that postmenopausal women who had the lowest amounts of B12 in their diet had an increased risk for breast cancer. Male infertility
Studies suggest that vitamin B12 supplements may improve sperm counts and sperm’s ability to swim.

Symptoms Of Vitamin B12 Or Folate Deficiency
Anaemia is the general term for having either fewer red blood cells than normal or having an abnormally low amount of haemoglobin in each red blood cell. For example, iron deficiency anaemia happens when the body does not contain enough iron.

a sore and red tongue
mouth ulcers
muscle weakness
disturbed vision
psychological problems, which may include depression and confusion
problems with memory, understanding and judgement Some of these problems can also happen if you have a deficiency in vitamin B12 or folate but do not have anaemia.
