5 Signs of Vitamin D Deficiency

22 Comments

Vitamin D deficiency is a pretty common condition. Sadly, very few people realize that their health is at risk, so they choose to ignore the side effects. Even though milk products have substantial quantities of vitamin D, that is still not enough to maintain bone strength and stay healthy.

In fact, the main source of this vitamin is not food, but the sun. Only natural sunlight provides enough for your body to look and feel good. Unfortunately, older adults do not get outside much, and because they spend a lot of time indoors, it is easy for them to become deficient.

Here are five clear signs of vitamin D deficiency to watch out for:

  1. Weak muscles: In aging adults, this deficiency is strongly linked to weak muscles. Older people are susceptible to developing a deficit due to several factors such as diminished exposure to direct sunlight, insufficient dietary intake, less-than-optimal intestinal absorption, and reduced skin thickness. Weakening of the muscles can manifest in different ways. In general, older adults feel a heaviness in their legs and difficulty with standing up and climbing stairs. The good news is that supplementation can help older adults compensate for these insufficiencies, and thus get back on their feet.
  2. Mood changes: This is not your average vitamin. In fact, in its activated form, it is a hormone. After your skin has been exposed to UVB rays, it synthesizes the inactive form, which relocates to the kidneys and liver, where it is then activated and ready for use. This hormone helps assimilate calcium, and keeps bones, muscles and teeth in excellent condition. Studies have shown that it is also responsible for activating genes that control the release of neurotransmitters (serotonin, dopamine); thereby affecting the functions of the brain. Seniors who feel depressed and tired all the time may actually suffer from a this deficiency. (Learn more about the Link Between Depression and Dementia.)
  3. Weight gain: Research claims that, together with a hormone called leptin, it helps regulate body weight. Leptin is manufactured inside the body's fat cells and works by delivering signals to the human brain, basically letting a person know that they're full and they can stop eating. Vitamin D controls leptin levels inside the body, making sure that the right signals are sent to the brain. When someone is deficient, these signals get disrupted and the body doesn't know when to stop eating. This can make people overeat and gain weight.
  4. Fatigue: Many older adults who feel tired do not realize that they might have a deficiency, so they choose to ignore their symptoms. Someone who has stiff joints and is constantly feeling fatigued might want to boost their intake (especially if they do not go outside much or do not eat many milk products). Apart from fatigue, this deficiency may also trigger pain in the legs and difficulty moving around the house.
  5. Stomach problems: This deficiency may lead to inflammatory bowel disease, which is a chronic illness that causes swelling and irritation in the digestive tract. This condition is split into two main types: ulcerative colitis and Crohn's disease. Older adults are more predisposed to developing inflammatory bowel disease because they are susceptible to this deficiency. Gut problems are unpleasant and they can also tamper with the fat absorption process. Since it falls into the category of fat-soluble vitamins, insufficiencies may trigger severe gastrointestinal problems. (Discover what it is like to Live with Irritable Bowel Syndrome.)

Vitamin D is an extremely important nutrient that the body needs to function properly, and insufficiencies may trigger severe health problems. Older adults who get little sunlight should make a lifestyle change if they want to preserve their health, maintain strong bones and have a healthy digestive tract.

Exposure to more natural sunlight, especially in the morning, is a simple activity that will yield positive results. Take relaxing walks to the park and enjoy the beautiful weather. This will boost your mood and keep your bones strong and healthy. Supplements may be advised if your deficiency is extremely severe, but it is a decision you'll have to discuss with your physician before starting.

I'm so glad you posted this article for public awareness. Even people that are under 60 can be Vitamin D deficient (I can attest to that as my last blood test showed me borderline deficient. My dr advised vitamins and to have another blood test in 6 months). Because I work inside (and, am inside most of the fall/winter) I need to make a bigger effort to get outside. Thank you!
Dr Michael F Holick, MD, PhD, is an award-winning researcher in the field of vitamin D:

I can't post the link here because it is a "dot com", but you can see his 98 minute discussion of information if you will type "dr michael f holick youtube" in your Google search bar.

I could be misquoting him, but I believe he said that every time he discovers something else that vitamin D is responsible for, he takes a little bit more.

In one of his research projects, he was able to demonstrate that even 5 months on 10,000 I.U.s per day did not produce toxicity.
My endocrinologist told me several years ago that it only takes 15 minutes of direct sunlight on our forearms to produce vitamin d between 9 am and 3 pm. Sunshine indoors through a window will not produce vitamin d.

When the UV rays from the sun hit the skin, a chemical reaction happens and your body converts a prohormone in the skin into vitamin d.

10 years ago, when I was 48, my doctor discovered that I had a very bad vitamin d deficiency. Among other things, this vitamin is crucial for the absorption of the calcium in our diet to keep our bones healthy. However, I had more problems than that. I also had osteoporosis and not just because of a vitamin d deficiency, but also because of a testosterone deficiency due to my pituitary gland not telling my body to make testosterone. For men, testosterone is the cement that takes the calcium absorbed by vitamin d and creates healthy bones. For women, a decrease in estrogen takes place after menopause and contributes to the development of osteoporosis.
