Can folic acid deficiency cause vomiting?
Patients may present with gastrointestinal (GI) signs and symptoms, such as nausea, vomiting, abdominal pain, and diarrhea, especially after meals. Anorexia also is common and, in combination with the above symptoms, may lead to marked weight loss.
What is the pathophysiology of folate deficiency anemia?
Most folate-deficiency anemia is caused by a lack of folic acid in the diet. Leafy vegetables, citrus fruits, beans, and whole grains are natural sources of folic acid. Folate-deficiency anemia in pregnancy may cause a neural tube defect. This is when the brain or spinal cord doesn’t develop normally.
What is the pathophysiology of megaloblastic anemia?
Pathophysiology. The pathophysiology of this group of anemia is ineffective erythropoiesis secondary to intramedullary apoptosis of hematopoietic cell precursors, which results from DNA synthesis abnormalities. Both vitamin B12 and folate deficiencies may cause defective DNA synthesis.
What type of anemia is associated with vitamin B12 and B9 deficiency?
Either a lack of vitamin B-12 or a lack of folate causes a type of anemia called megaloblastic anemia (pernicious anemia). With these types of anemia, the red blood cells don’t develop normally. They are very large. And they are shaped like an oval.
How does B9 deficiency manifest?
Vitamin B9 deficiency can lead to anaemia and might increase your risk of heart disease. It’s also really important during early pregnancy for a developing baby. Signs of deficiency include tiredness, weakness, shortness of breath, heart palpitations, and difficulty concentrating.
What causes low B12 and folate?

How does B12 deficiency cause megaloblastic?
The two most common causes of megaloblastic anemia are deficiencies of vitamin B12 and folate. These two nutrients are necessary for producing healthy RBCs. When you don’t get enough of them, it affects the makeup of your RBCs. This leads to cells that don’t divide and reproduce the way they should.
What is the pathophysiology of anemia?
At a biological level, anemia develops because of an imbalance in erythrocyte loss relative to production; this can be due to ineffective or deficient erythropoiesis (e.g., from nutritional deficiencies, inflammation, or genetic Hb disorders) and/or excessive loss of erythrocytes (due to hemolysis, blood loss, or both) …
What is pernicious Anaemia?
Pernicious anaemia is an autoimmune condition that affects your stomach. An autoimmune condition means your immune system, the body’s natural defence system that protects against illness and infection, attacks your body’s healthy cells. Vitamin B12 is combined with a protein called intrinsic factor in your stomach.
