Vitamin D deficiency in Nepal

Posted on : February 14, 2020 by Clinic One on Blog

Vitamin D deficiency simply means a deficiency of vitamin D in your body. Vitamin D is produced by the human body using sunlight.

It is an essential vitamin that the body requires for strong bones. Deficiency in Vitamin D is the main cause of body pain, especially among youngsters. Vitamin D is related to calcium absorption by the body, and its deficiency leads to rickets and many other problems.

Vitamin D helps the absorption of calcium and magnesium and prevents many diseases. About 90% of Vitamin D is produced by sunlight, whereas the remaining 10% is produced from other foods and supplements such as egg yolk, seafood, fortified dairy products, etc. It is very hard to get enough from your diet alone.

Active people in the sun produce most of the vitamin D that they need from their skin. The two major forms of vitamin D are:

  • Vitamin D2 (ergocalciferol): this is produced by UV irradiation of ergosterol, which occurs in yeast, molds, and higher-order plants.
  • Vitamin D3 (cholecalciferol): this is photosynthesized in the skin of vertebrates by the action of solar ultraviolet. Vitamin D3 is only found in animal-source foods.

There are basically three ways a body can get vitamins: from the skin, supplements, and your diet.

Unlike other vitamins, vitamin D functions like a hormone, and every single cell in your body has a receptor for it. The most accurate measure of vitamin D in your body is

  • If it is less than 20ng = Deficient
  • If it is between 20 – 29 ng = Insufficient
  • If it is between 30 – 100 ng = Normal

Vitamin D Deficiency in Nepal and Worldwide

In Nepal, 60% of people suffer from Vitamin D deficiency. The exact data of the people who are affected by vitamin D deficiency is unavailable, but the people who are living in the Kathmandu Valley are at a very high risk of Vitamin D deficiency, which leads to a host of medical compilations.

According to some research done in Pokhara in 2014–2015, about 75% of the people who were admitted to the hospital were found to be low in Vitamin D.

As people adopt an urban lifestyle, they tend to stay at home a lot, not work, or stay under the sun.

Not only in Nepal, Vitamin D deficiency is a worldwide problem, and this has had an impact on billions of people. 30% of the male population and 46% of the female population are affected by vitamin D deficiency.

Vitamin D deficiency is common in all age groups. As there is low sunlight in the middle east and the southern part, there are more chances of vitamin D deficiency.

It was found that females are more affected by Vitamin D than males. Child birthing women, or those women that have given birth to a child, and other religious practices that are being done by the people by which the women have to cover the whole parts of their body when they go anywhere or when they are at home have the most chances of Vitamin D deficiency.

It helps your body to absorb calcium by which your bones can stay strong especially for the people above the age of 40 because as they are growing old their bones start to get weaker. Research has shown that people with Vitamin D deficiency have a higher chance to get back pain. Studies have shown that calcium and Vitamin D together can build stronger bones by which back pain also can be reduced. Low blood levels of Vitamin D may be a cause or contribution factor to bone pain and lower back pain.

Why do women have more Vitamin D deficiency in Nepal?

Women are more likely to have Vitamin d deficiency in Nepal than that of the Male. As in Nepal because of the cultural and traditional believes child birthing women or those women who have already given birth to a child have higher chances of getting vitamin D deficiency as they are not allowed out of their homes or they should cover their whole body with clothing by which sunlight cannot touch their body. According to the doctors, only the foods cannot satisfy the vitamin D that is needed in a human body only 20% can be covered by the supplementary and food but the rest 80% is covered by the sun. As Nepal is a developing country, houses are constructed in such a way that they leave no way for the sunlight to pass which leads to Vitamin D deficiency. Women are usually found to be suffering after menopause due to lack of estrogen hormone which causes weakening of bones. Females are greatly affected by Vitamin D deficiency as there is very low intake of nutrition in them. Females are lacking in vitamin D because of the hormones the female body needs more vitamin D for cell production or regeneration compared to that of the male.

How can we prevent Vitamin D deficiency (lifestyle and home remedies)?

As the amount of vitamin D that a human body needs at a normal level is 25 hydroxyvitamin D not only that it also depends upon your skin color, sun exposure, medical conditions, balanced diet, etc. The goal of treating a vitamin D deficiency is to reach and keep an adequate level of vitamin D in your body. As vitamin D helps a body to function properly by keeping the bones strong, muscles strong, etc. So we can prevent it by

  • Eating more foods containing vitamin D:

As Vitamin D is quite important to keep the human body strong, a balanced diet is also important for a healthy body. Without a proper diet, the body will not be able to function. Vitamin D sources include

  1. Eggs: Eggs are one of the main protein that contains high in Vitamin D not only in Vitamin D they have almost all the vitamin that a human body needs.
  2. Dairy Products: Dairy Products are also another main source of Vitamin D. Dairy products such as milk not only contains Vitamin D but they are rich in calcium which helps to keep the bones strong and also most dairy products are cheaper comparing them with others.  
  3. Fish: Fatty fish such as tuna, salmon is a great source of Vitamin D. Oily fish, as well as oils from fish, have some of the highest quantities of Vitamin D in food source which might also include cod liver oil, herring, swordfish, etc.
  4. Mushroom: Mushroom is also high in Vitamin D. If a person does not like fish or they are vegetarian it is a great option for securing vitamin D. All the mushrooms are not the same. Especially button mushrooms are high in vitamin D and thus are a good option for Vegans.

Getting Exposure to Sun Light:

        Sunlight is one of the major sources of Vitamin D. Every person should get exposure to sunlight each day. As people do not have the same lifestyle so about 10 to 20 mins each day 3 to 4 times a week should be enough. But different age people need a different amount

Birth to 12 months  =  400 IU

Age 1-70 years = 600 IU

Age 70+ years = 800 IU

Lifestyle plays a vital role in Vitamin D deficiency some people are willing to change and help themselves in removing the deficiency whereas some may not. Also, people who use sunscreen and people who sit in the sun behind the window cannot get Vitamin D properly as the window is blocking the UV rays to enter your body. But too much of sitting in the sun might cause skin burn or skin cancer. As all the people are unable to expose their skin to the sun due to lack of sunlight those people should take those supplements all year long so as to maintain the vitamin D level in their body.

Treatment of Vitamin D deficiency

Sometimes intake in Vitamin D is not sufficient so supplements are required. Vitamin D2 and Vitamin D3 are recommended by doctors. The doctors recommend  daily  intakes must be taken by patients to prevent Vitamin D deficiency  and maximize bone strength
