Causes Of Severe Vitamin D Deficiency In Adults
Vitamin D is an essential nutrient that helps the body absorb calcium and phosphorus, which are necessary for strong bones and overall health. Unfortunately, many adults suffer from severe vitamin D deficiency, which can lead to a range of health problems. In this article, we will explore the causes of severe vitamin D deficiency in adults.
Lack of Sun Exposure
Sun exposure is one of the primary ways that the body produces vitamin D. When the skin is exposed to sunlight, it synthesizes vitamin D from cholesterol. However, many adults do not get enough sun exposure due to their lifestyle, work environment, or climate.
People who live in northern latitudes or areas with limited sunlight may be at a higher risk of vitamin D deficiency. Additionally, individuals who spend most of their time indoors or cover their skin with clothing or sunscreen may not produce enough vitamin D.
Poor Diet
Vitamin D is found in a limited number of foods, including fatty fish, egg yolks, and fortified milk and cereals. If an adult's diet does not include these types of foods, they may be at risk of vitamin D deficiency. Vegans and vegetarians, in particular, may have a harder time getting enough vitamin D from diet alone.
Medical Conditions
Some medical conditions can interfere with the body's ability to absorb or use vitamin D. For example, individuals with Crohn's disease or celiac disease may have trouble absorbing vitamin D from food. Additionally, obesity can cause vitamin D to be stored in fat cells rather than circulating in the bloodstream.
Age
As we age, our skin becomes less efficient at synthesizing vitamin D from sunlight. Additionally, older adults may be less likely to spend time outdoors or have a poor diet, further increasing their risk of vitamin D deficiency. Women who have gone through menopause may also be at a higher risk of vitamin D deficiency due to hormonal changes.
Conclusion
Severe vitamin D deficiency can lead to a range of health problems, including weakened bones, increased risk of infections, and even depression. By understanding the causes of vitamin D deficiency, adults can take steps to ensure they are getting enough of this essential nutrient. This may include spending more time outdoors, adjusting their diet, or taking vitamin D supplements under the guidance of a healthcare provider.
