Vitamin D deficiency can cause a range of health problems




Since learning Vitamin D can help fight COVID- 19, what are signs of Vitamin D deficiency?

In the September 25 issue, we talked about how vitamin D possibly can help ward off COVID- 19 virus and lessen its severity if you do get it, according to a Healthline newsletter article by Franziska Spritzler. The report prompted more questions about the signs of a vitamin D deficiency. Again, we referred to Healthline for an article by Spritzler, a registered dietician, about the problems such a deficiency can cause.

Here are eight signs and effects of a Vitamin deficiency, as summarized by her.

1. Getting sick often—If you often become sick, especially with colds or the flu, low vitamin D levels may be a contributing factor. Studies have shown a link between a deficiency and respiratory tract infections like colds, bronchitis and pneumonia.

2. Fatigue—A vitamin D deciency is one often overlooked cause of fatigue, although there are others. Taking supplements may help improve energy levels.

3. Bone and back pain—Vitamin D helps maintain bone health in several ways, so low levels may cause pain in your back lower back and bones. For one, vitamin D improves your body’s absorption of calcium. In one study, people with vitamin D deficiency were nearly twice as likely to experience bone pain.

4. Vitamin D deficiency contributes to depression—Some studies have shown that giving vitamin D to people who are deficient helps improve depression, including seasonal depression.

5. Impaired wound healing—Slow healing of wounds after surgery or injury may be a sign that your vitamin D levels are too low. Vitamin D may also have a role in controlling inflammation and fighting infection as well as healing.

6. Bone Loss—Vitamin D plays a crucial role in calcium absorption and bone metabolism. While people may think first of a calcium deficiency as a cause, a lack of vitamin D may be a factor. Adequate vitamin D is important in protecting bone mass and reducing fracture risk.

7. Hair Loss—Hair loss or alopecia is often attributed to stress, certainly a common cause, but severe hair loss may also be caused low vitamin D levels.

8. Muscle Pain— Although there are many causes of muscle pain, there is evidence vitamin D deficiency may cause muscle pain. There is a link between chronic pain and low blood levels of vitamin D, which may be due to the interaction between the vitamin and pain-sensing nerve cells.

In summary, vitamin D deficiency can be quite common with many people unaware they are affected. It is important to consult your health care provider to determine if that is the case. While a deficiency in vitamin D can cause many ailments, there is also a possibility of getting too much of vitamin d as well. Make sure you avoid excessive doses of vitamin D. Generally, 4,000 IU or less per day is considered safe if your blood values are being monitored.

Signs of too much vitamin D in your system can include elevated blood calcium levels; digestive distress, such as vomiting, nausea, and stomach pain; fatigue, dizziness, and confusion; excessive thirst; and frequent urination. If you’ve been taking vitamin D supplements and experience these symptoms, again consult your health care provider.
