Vitamin D, also known as vitamin A, is one of the most important vitamins that has a great impact on several systems throughout the body. Unlike other vitamins, vitamin D acts as a hormone, and each cell in the human body has a receptor for it. When the skin is exposed to sunlight, the body produces this vitamin with cholesterol.
Of course vitamin D is also present in some foods. In any case, the best way to provide vitamin D, the body skin is 2 to 3 times a week, and exposed to sunlight for 5 to 10 minutes each time. It should be noted that this vitamin is destroyed at relatively high rates in the body and should always be careful, especially in winter, to reduce its storage in the body. This vitamin will be discussed further. The causes, symptoms, and complications of the deficiency will be discussed and, finally, the amount of vitamin D required in the body will be addressed.
Causes of vitamin D deficiency
New studies show that many people are deficient in vitamin D. It is estimated that the amount of vitamin D in the blood of around 1 billion people worldwide is lower than normal. Some of the causes of vitamin D deficiency in the body include:
Having dark skin
Living in areas where there is not much sunshine during the year
Permanent use of sunscreen
Not taking foods containing vitamin D
Symptoms of vitamin D deficiency
Many people are not aware of the low levels of vitamin D in their body, because this deficiency has some signs. Some of the symptoms of vitamin D deficiency in the body include:
1. Frequent incidence of colds and influenza
One of the most important roles of vitamin D is the strengthening of the immune system. Studies indicate the link between vitamin D deficiency and various types of respiratory infection such as colds, bronchitis, and the like. Some studies have shown that taking 4,000 IU of vitamin D supplementation reduces the risk of developing respiratory infections per day.
One study found that children who received 1200 IU of vitamin D every 4 months during the winter had a 40% lower incidence of type A influenza.
One of the causes of persistent tiredness is vitamin D deficiency, which unfortunately is often ignored as a potential cause. A major study has been done on the relationship between fatigue and vitamin D deficiency in young women. The study found that vitamin D levels in their blood were less than 29-21 ng / mm, and those who complained more than fatigue than women whose blood levels of vitamin D were more than 30 ng / mm.
Bone pain and back pain
Vitamin D helps in the health of bones in various ways, such as improving the absorption of calcium. Bone pain and back pain can be signs of vitamin D deficiency in the body. Many observations have been made between vitamin D deficiency and chronic low back pain. Another study found that people with vitamin D deficiency had twice as many people who did not have this deficiency during the daily activities of the pain in the legs, ganglia or joints.
Researchers have found links between vitamin D deficiency and depression, especially in adults. However, some researchers have found that there is not much time to see how vitamin D supplementation affects mood. Vitamin D, in particular, helps people with seasonal depression in the cold months of the year.
5. Improvement of injuries
Improving wounds and injuries after accidents or surgeries can be a sign of vitamin D deficiency. Research has shown that vitamin D plays a vital role in the production of a combination that heals wounds.
Many adults with osteoporosis do not need to consume more calcium because their problem is actually vitamin D deficiency. Osteoporosis is the most common bone disease among postmenopausal women and older men. In a study of more than 1,100 middle-aged men close to menopause, researchers found a strong link between low levels of vitamin D and low bone density. However, another study showed that with increasing vitamin D supplementation, recovery in bone density is still not achieved, yet enough vitamin D can be considered as a good way to protect bone mass and reduce the risk of bone fractures.
7. Hair loss
Hair loss may be associated with a low level of vitamin D in the blood. The tetany, a type of autoimmune disease, is associated with racism, a disease caused by vitamin D deficiency in children. Lack of this vitamin increases the likelihood of developing a scrotum.
8. Muscle pain
Some evidence suggests that vitamin D deficiency is a potential cause of muscle aches in children and adults. One study showed that 71% of people with chronic muscle pain had vitamin D deficiency.
Complications of long-term vitamin D deficiency
In addition, if vitamin D deficiency continues in the body for a long time, it can cause the following diseases and diseases:
Chronic fatigue syndrome
Neurodegenerative diseases such as Alzheimer's
Vitamin D deficiency can also affect some types of cancer, especially breast cancer, prostate, and large intestine.
The amount of vitamin D required by the body
The amount of vitamin D required by the body depends on the individual's age. This value can be calculated using two types of measurement unit: microgram (mcg) and unit
