Scurvy in Seniors: Vitamin C Deficiency, Symptoms and Prevention Guide

What Are the Common Causes and Risk Factors?

Understanding scurvy seniors prevention is important for seniors and their caregivers. folic acid (vitamin B9) works with vitamin B12 and vitamin C to help the body break down, use, and make new proteins. The vitamin helps form red and white blood cells. It also helps produce DNA, the building block of the human body, which carries genetic information.

Folic acid is a water-soluble type of vitamin B. This means it is not stored in the fat tissues of the body. Leftover amounts of the vitamin leave the body through the urine.

Because folate is not stored in the body in large amounts, your blood levels will get low after only a few weeks of eating a diet low in folate. Folate is found primarily in legumes, leafy greens, eggs, beets, bananas, citrus fruits, and liver.

Contributors to folate deficiency include:

• Diseases in which folic acid is not well absorbed in the digestive system (such as

  celiac disease

  or

  Crohn disease

  )

• Drinking too much alcohol
• Eating overcooked fruits and vegetables. Folic acid can be easily destroyed by heat.

• Hemolytic anemia

  which results in the need for more folic acid to make red blood cells

• Certain medicines (such as phenytoin, sulfasalazine, or trimethoprim-sulfamethoxazole)
• Eating a diet that does not include enough fruits and vegetables
• Kidney dialysis

What Are the Symptoms and Warning Signs?

Folic acid deficiency may cause:

• Fatigue, irritability, or diarrhea
• Poor growth
• Smooth and tender tongue

What Are Exams and Tests?

Folate deficiency can be diagnosed with a

. Pregnant women commonly have this blood test at prenatal checkups.

What Are Possible Complications?

Complications include:

• Anemia

  (low red blood cell count)

• Low levels of white blood cells and platelets (in severe cases)

In

, the red blood cells are abnormally large (megaloblastic).

Pregnant women need to get enough folic acid. The vitamin is important to the growth of the fetus’s spinal cord and brain. Folic acid deficiency can cause severe birth defects known as

. The Recommended Dietary Allowance (RDA) for folate during pregnancy is 600 micrograms (µg)/day.

How Is It Prevented?

• Mushrooms
• Poultry, pork, and shellfish
• Wheat bran and other whole grains

The recommended daily amount of folic acid for adults is 400 µg of folate daily. Women who may become pregnant should take

to ensure that they get enough each day.

depend on a person’s age, sex, and other factors (such as pregnancy and lactation). Many foods, such as fortified breakfast cereals, now have extra folic acid added to help prevent birth defects.
