Vitamin D is an essential body nutrient that is needed in several body systems for them to function effectively. Unlike other essential body nutrients, Vitamin D also acts as a hormone, and all cells in the body have a receptor for it.

It is also contained in certain foods such as fatty fish and dairy products. However, the amount of Vitamin D in foods is usually not sufficient for all its bodily functions. To know if you have sufficient vitamin D, you need private vitamin D blood testing in London.  

The recommended daily intake (RDI) is 400– 800 IU, but some experts recommend that your daily vitamin D intake should exceed this number.

With the high need for this vitamin in the body, most people are not able to get enough of it. A study in 2011 found that most people are Vitamin D deficient.

Some common factors that make most people vitamin D deficient include

  • Living in places with low sunlight all year-round

  • Eating less offish and dairy products

  • Always wearing sunscreen when outdoor

  • Being overweight or obese

  • Being elderly

  • Having dark skin

People who are always exposed to sunlight are more likely to have sufficient Vitamin D to meet all their bodily needs.

Most times, people are unaware that they are vitamin D deficient because most symptoms of vitamin D deficiency are usually mild. They may not be easily recognized even when they have a significant effect on the way the body’s systems work so you would need private blood tests near me to know if you are deficient of the vitamin.

Below are 8 signs and symptoms that could be an indication of vitamin D deficiency

1.    Getting sick or infected frequently

A major function of vitamin D in the body is strengthening the immune system to fight against viruses and bacteria that cause infections and diseases. Vitamin D works by directly interacting with the cells that fight infections.

If you are always sick, especially with a cold or the flu, your vitamin D levels may be low and contributing to your weakened immune system. Different studies have shown that there is a link between vitamin D deficiency and respiratory tract infections such as common cold, bronchitis, and pneumonia. These studies have also shown that taking vitamin D supplements which are up to 4000 IU everyday may help reduce your risk of contracting respiratory tract infections.

Ina study with people who had chronic lung disorder, those who were severely deficient in vitamin D experienced significant improvement after taking vitamin D supplement for one year.

2.    Fatigue and tiredness

Always feeling tired can be caused by many factors, and vitamin D deficiency is one of them. However, it is often overlooked as the cause of fatigue.

Some case studies have shown that very low blood levels can cause fatigue and have other negative effects. Even when your blood level is not extremely low, it can affect your energy level. A study that looked at the link between vitamin D and fatigue in women showed that women with blood levels lower than 20ng/ml or 21 –29 ng/ml complained more of fatigue than those with blood levels above 30ng/ml.

Another observational study in female nurses showed that most of the nurses who complained about fatigue had low vitamin D levels.

3.    Bone and back pain

Vitamin D has been helpful in the absorption of calcium which maintains the strength of the bone. Constant bone and back pain may be a sign of vitamin D deficiency.

A study showed that there was a connection between chronic back pain in about 9,000 elderly women and their vitamin D levels. The researchers found that those who were vitamin D deficient had severe back pain and limited daily activities.

In a controlled study about vitamin D deficiency showed that those deficient in the vitamin were more likely to have bone pain in their legs, ribs or joints.

4.    Depression

Being depressed may be a sign of vitamin D deficiency. In some review studies, there searchers found that depression in older adults was due to low vitamin D levels. However, these studies have not been confirmed.  

5.    Delayed wound healing

One of the causes of slow healing of wounds after a surgery or an injury is vitamin D deficiency. A test-tube study suggested that normal vitamin D levels increased the production of compounds that are essential in the formation of new skin which is a vital part of wound healing.

Another study on people who had dental surgery showed that a vital part of their healing process was influenced by their vitamin D levels.

Vitamin D also controls inflammation and helps fight off infection, which is also a vital part of wound healing. Several other studies have shown that the right intake of vitamin D supplements help wounds heal faster.

6.    Bone loss

Vitamin D is an essential compound in the process of calcium absorption and bone metabolism. Loss in calcium and other minerals leads to low bone mineral density which increases the risk of fractures. Some observational studies found a link between low vitamin D level and low bone mineral density while a controlled study disapproved this finding.

However,having adequate vitamin D levels and maintaining the right blood levels would help protect your bone mass and reduce the risk of fracture.

7.    Hair loss

Hair loss is often linked to stress, but when the loss becomes severe, it could be a result of a disease or deficiency in certain nutrients. Low vitamin D levels are associated with alopecia which is an autoimmune disease characterized by hair loss from the head down to other body parts.

8.    Muscle pain

Muscle pain can be caused by several factors, but it is usually difficult to get the actual cause of the pain. Some studies found that taking vitamin D supplements help reduce different types of pain and that those who experience severe pain were lacking in nociceptors which is a vitamin D receptor.
