Vit C Def

vit c


Vitamin C is not produced by the human body and so is an essential component of the diet. It is required for the health and repair of various tissues in the body, including skin, bone, teeth and cartilage. Chronic (persistent) lack of vitamin C in the diet can lead to a condition called scurvy. Symptoms of scurvy include easy bruising, spontaneous bleeding and joint and muscle pains. Vitamin C deficiency can be treated with supplements of vitamin C and a diet rich in vitamin C.

What do you understand by Vitamin C?

Vitamins are substances which are needed i by the body to maintain  goodhealth. Vitamin C is also called ascorbic acid. It is needed to make a substance called collagen which is required for the health and repair of various tissues in the body, including:

  • Skin
  • Bone
  • Cartilage
  • Ligaments and tendons
  • Blood vessel walls
  • Teeth

What are the main sources of Vitamin C?

There are various foods that are rich in vitamin C, including:

  • Citrus fruits like oranges, grapefruit, limes and lemons.
  • Berries such as blackcurrants, strawberries, raspberries, blueberries and cranberries
  • Watermelon.
  • Kiwi fruit.
  • Vegetables such as spinach, green and red peppers, tomatoes, cauliflower, cabbage, broccoli, brussels sprouts and potatoes.
  • Certain foods such as cereals are fortified with vitamin C, which means that they have vitamin C added to them. Vitamin C is also found in fresh milk, fish and offal such as liver and kidney.

How much Vitamin C is required?

Around 90% of vitamin C in the human diet is from fruit and vegetables. Cooking fruit and vegetables reduces their vitamin C content by around 30-40%. The recommended daily intake of vitamin C in the diet depends on your age and sex. Pregnant and breast-feeding women also need higher amounts of vitamin C in their diet.

Children aged 1-10 years need 30 mg of vitamin C per day.

Children aged 11-14 years need 35 mg of vitamin C per day.

Children over the age of 15 years and adults need 40 mg per day.

What is vitamin C deficiency?

Deficiency, or a lack, of vitamin C in the body happens because of a lack of sufficient amounts of vitamin C in the diet. This means that new collagen cannot be formed and various tissues in the body  start to break down and the health and repair of the body becomes affected. Chronic (persistent) vitamin C deficiency, usually over a period of around three months or more, can lead to an illness known as scurvy.

Who are more prone to have vitamin C deficiency?

There are certain groups of people who are more at risk of vitamin C deficiency. They include:

  • Victims of famine, and refugees.
  • People dependent on drugs and/or alcohol who may not have a healthy, balanced diet.
  • People who go on fad diets.
  • People living on a low income who tend not to buy foods with a high vitamin C content.
  • People with a medical condition that affects the body's ability to digest and absorb food such as Crohn's disease and ulcerative colitis.
  • Older people who may eat a less varied diet.
  • Smokers. Smoking affects the absorption of vitamin C from foods and also vitamin C is used up in the body more quickly in those who smoke.
  • Pregnant and breast-feeding women because they need higher amounts of vitamin C.

What investigation are required?

Generally the doctor would make the diagnosis by history and examination. In some cases blood tests would be required to find out the serum concentration of vitamin C in the body. Some tests would also be required to rule out other bleeding disorder condition, which present the same way.

X-rays to look at your bones may also be suggested because specific changes to the bones, including thinning of the bones, are often seen in someone with vitamin C deficiency.
