Nearly 1 billion people in the world have a deficiency of vitamin D. There's a good chance that you or someone you know has this deficiency. While the sun is a main source of getting enough vitamin D, the problems is that a lot has changed, making it more and more difficult to get the proper amount. In order to avoid dealing with a vitamin D deficiency, you'll want to know more about this deficiency and how to prevent it.

What Are the Symptoms of Vitamin D Deficiency?


Gut conditions

Crohn's disease, celiac, inflammatory bowel disease and other gastrointestinal conditions can indicate a deficiency in vitamin D. If you have troubles with absorbing fat-soluble vitamins, you won't be able to probably get enough this vitamin.


Excessive sweating of the head

One of the first and most common indications of a deficiency in vitamin D is head sweating. If you notice that your forehead sweats when you are not partaking in physical activity and your body temperature remains at its normal range, then there is a good chance that this is due to not getting enough vitamin D.


Muscle weakness

While exercising regularly can help maintain strong and flexible muscle, when you aren't getting enough vitamin D, you not only will feel fatigued, but also you won't have the energy or power to perform your daily activities.


Osteoporosis symptoms

After the age of 30, your bones begin to stop building mass and not getting sufficient vitamin D speeds up this loss of mass. Early signs of osteoporosis or an increase in bone weakness and breakage can indicate you are not getting enough vitamin D every day.



A lack of vitamin D can cause long-lasting widespread pain throughout the body. Often people are misdiagnosed as having fibromyalgia or arthritis when in fact their pain is the result of not enough vitamin D.



It is unclear why vitamin D deficiency can cause depression symptoms in a number of people, but if you find yourself feeling more and more sad, there's a good chance the problem is with you vitamin D intake.



People who are overweight or obese will have a more difficult time absorbing the proper amount of vitamin D their body needs. Since vitamin D is a fat soluble vitamin, the more fat you have, the more vitamin D your body will need to be provided with.


Increase in infections

Vitamin D helps boost the immune system's ability to fight off bacteria and infections. If you are not getting enough vitamin D, then you will most likely suffer from more colds and the flu.

What Causes Vitamin D Deficiency?



Those who eat a strict vegan diet increase their chances of a vitamin D deficiency. Most of the vitamin D you consume is through foods and is often found in animal-based foods like beef liver, eggs, and fish.


Lack of sunlight

Vitamin D is produced in the skin through the absorption of the sunlight. Staying indoors for too long or constantly being covered when outdoors limits the amount of sun your skin is exposed to.


Having darker skin

Those with darker skin have a more difficult time producing vitamin D from the sun. The melanin pigment, which is more prominent in people with darker skin, is the main cause for this inability to produce vitamin D.


Kidney issues

Deficiency of vitamin D is common among those who have problems with their kidneys. This becomes more of a concern the older you get, because when you age, your kidneys are less able to convert vitamin D for the body to absorb.



Those with a body mass index over 30 will often have less vitamin D in their body's. Not only will they have less but the excess fat cells prevent to proper release and absorption of the vitamin D in the body.
