Vitamin D is a very important vitamin that has a powerful effect on many body systems (a reliable source).
Unlike other vitamins, vitamin D acts like a hormone, and each of your cells has receptors for it.
The body gets it from cholesterol when the skin is exposed to the sun.
Here are the common risk factors for vitamin D deficiency:
-skinned being old
Overweight or obese.
Don’t eat a lot of fish or dairy products.
Live far from the equator, where there is little sun throughout the year.
Always apply sunscreen when you go outside.
the rest of the interior.
People who live near the equator and are often exposed to the sun are less likely to develop a deficiency because their skin produces enough vitamin D to meet their physical needs.
Most of us do not know that they are spoiled, because the signs are usually invisible. They may not be easy to identify, even if they have a significant negative impact on the quality of life.
Here are the signs and symptoms of vitamin D deficiency.
- illness or injury often
One of the key functions of vitamin D is to maintain a strong immune system so that it can fight disease-causing viruses and bacteria.
It interacts directly with the cells responsible for fighting infections (reliable source 4).
If you get sick often, especially with a cold or flu, low vitamin D levels are partly to blame.
Several observational studies have shown an association between deficiency and respiratory infections such as colds, bronchitis and pneumonia (5.6).
- fatigue and fatigue
There can be many reasons for feeling tired, and vitamin D deficiency is one of them.
Unfortunately, this often goes unnoticed, this may be the reason.
Case studies have shown that very low blood sugar levels can cause fatigue, which has a serious negative impact on the quality of life (11, 12).
- bone and back pain
Vitamin D helps maintain bone health in many ways.
First of all, it is the best absorption of calcium in the body.
Bone pain and lower back pain may be signs of insufficient vitamin D levels in the blood.
Depressed mood can also be a sign of vitamin D deficiency.
In a review of studies, researchers linked vitamin D deficiency to depression, especially in adults (19, 20).
In one analysis, 65 percent of observational studies found a link between low blood counts and depression.
- Poor wound healing
Slow healing of wounds after surgery or injury may be a sign of low vitamin D levels.
According to Glass’s research, as a result of the wound healing process, vitamin A increases the production of compounds necessary for the formation of new skin (23).
One analysis looked at patients with diabetic foot infections
He found that people with severe vitamin D deficiency were more likely than others to have higher levels of inflammatory markers that could threaten health (25).
- bone loss
Vitamin D plays an important role in calcium absorption and bone metabolism.
Many adults with bone loss believe that they need to consume more calcium. However, you may also have a vitamin D deficiency.
Low bone mineral density is a sign that bones are losing calcium and other minerals. This puts adults, especially women, at risk of fractures.
However, a controlled study showed that women with vitamin D deficiency did not improve bone mineral density when taking high doses of supplements, even though their blood levels were better (28 Unreliable source).
