One billion. That’s the number of people worldwide who have a vitamin D deficiency, according to the Harvard School of Public Health. And a significant number of those people live in the United States. A study published in the Nutritional Journal put that number at 42 percent of American adults.
So what are the symptoms a person should look for to find out if they are included in this number or not? A blood test may be able to inform someone, but first here are some things to look out for when deciding whether or not to get a blood test or speak with a physician regarding possible vitamin D deficiency.
Unexpected lack of strength: A deficiency of vitamin D can make a person feel extremely tired, even if they’ve gotten regular amounts of sleep on most nights. Getting the appropriate daily intake of vitamin D supports keeping energy throughout the whole body. Researchers have even connected vitamin D supplements with increased muscle control.
Uncontrolled sweating: Excessive sweating, especially on the forehead, is one of the first signs of a vitamin D deficiency. If a person maintaining their activity levels in an environment with a moderate temperature, doesn’t have a fever, and is still sweating, this could be a symptom of a vitamin D deficiency and should be taken seriously. When someone is experiencing this, they should speak with a physician to see if a blood test is recommended.
Chronic pain: Some people with vitamin D deficiency experience subtle bone pains and aches. Because a vitamin deficiency can cause this to happen, oftentimes people diagnosed with arthritis or other illness that causes bone or joint pain also are deficient in vitamin D as well. Getting the right amount of vitamin D daily can aid in preventing pain after working out and speed up the muscle recovery process.
Feeling down: Depression and a deficiency in vitamin D tend to go hand in hand. Vitamin D might be effective in the same areas of the brain and affect the same hormones as the areas and hormones that are linked to depression. If a person has been diagnosed with depression, they should talk to a physician about a possible vitamin D deficiency too.
Since Vitamin D is primarily absorbed through the sun, it can be challenging to get the recommended daily dose — especially in varied climates. To ensure that you’re not experiencing a Vitamin D deficiency, consult a physician.
