Vitamin D deficiency is a major public health problem, particularly among elderly people and is associated with several geriatric syndromes. It is important for our bones, blood cells, and immune system.
In adults Vitamin D deficiency leads to a mineralization defect in the skeleton, causing osteomalacia, and induces secondary hyperparathyroidism with consequent bone loss and osteoporosis.
Symptoms of Vitamin D deficiency
Lack of vitamin D is not often obvious in adults. Some of the signs and symptoms might include:
- Bone pain.
- Muscle weakness, muscle aches, or muscle cramps.
- Mood changes, like depression.
- Cognitive impairment in older adults.
According to WebMD, there are several things that can raise your chances of having low levels of vitamin D:
- Age: Your skin and kidneys don’t make it as easily in your older years.
- Darker skin: It doesn’t convert sunlight as well.
- Digestive problems: Crohn’s disease, celiac disease, and problems with fat digestion can limit your levels.
- Obesity: Fat traps some vitamin D and stops it from getting into your blood.
How can you prevent vitamin D deficiency?
- Eat more foods that contain vitamin D.
- Get some exposure to sunshine.
- Take supplements.
It’s important not to take too much vitamin D. Vitamin D toxicity is rare but can be serious. If you are sick, homebound, 50+ or older, spend most of your time indoors, you might not get enough vitamin D. Talk to your doctor if you think your levels are low.
