5 Symptoms of Vitamin D Deficiency in Elderly Adults

Vitamin D insufficiency, also known as hypovitaminosis D, is a growing concern that affects individuals of all ages. However, older adults are at a heightened risk of this condition. The indications of low vitamin D levels are often not immediately apparent and may be mistaken for other health problems, particularly in the elderly population.

By familiarizing yourself with the sources of vitamin D, recognizing the warning signs of this dietary deficiency, and discovering ways to combat it, you can take proactive measures to ensure that your aging loved ones are receiving the vital nutrients they need to maintain their well-being.

What is vitamin D deficiency?

Vitamin D deficiency is a widespread condition that occurs when your body doesn’t have enough of this essential nutrient. This deficiency can lead to various issues related to your bones and muscles.

Vitamin D is a crucial nutrient that supports the normal development and maintenance of your bones. It also plays a vital role in your nervous, musculoskeletal, and immune systems.

There are multiple ways to obtain vitamin D, including exposure to sunlight, consumption of certain foods, and dietary supplements. However, some people may struggle to obtain enough vitamin D through these means, particularly those with darker skin or residing in regions with limited sunlight.

Despite the availability of various sources of vitamin D, deficiency remains a widespread problem globally.

Why is vitamin D so important?

Vitamin D is a vital nutrient that your body requires to maintain optimal health. It plays a significant role in regulating the balance of calcium in your bloodstream and bones, thereby supporting the growth, maintenance, and repair of your bones and tissues.

When your body is deficient in vitamin D, it struggles to absorb adequate amounts of calcium and phosphorus, leading to hypocalcemia or low calcium levels in the blood. This triggers the overactivity of the parathyroid glands, leading to secondary hyperparathyroidism, which can cause a range of symptoms such as muscle weakness, cramps, fatigue, and depression.

To compensate for the low calcium levels, your body starts taking calcium from your bones, leading to accelerated bone breakdown. This can ultimately result in osteomalacia or soft bones in adults and rickets in children. These conditions increase the risk of bone fractures and can cause bowed or bent bones in growing children.

Thus, it is essential to ensure that your body receives an adequate supply of vitamin D through diet, supplements, or sunlight exposure to maintain healthy bones and overall well-being.

Who does vitamin D deficiency affect?

Vitamin D deficiency is a condition that can affect individuals across all age groups, from infants to adults.

However, it is noteworthy that individuals with darker skin tones and those who prefer to wear clothing that covers a larger portion of their skin, particularly in Middle Eastern regions, are at a higher risk of developing this condition.

How common is vitamin D deficiency?

Vitamin D deficiency is a pervasive health concern that affects a staggering number of people worldwide. In fact, a billion individuals globally suffer from vitamin D deficiency, with half of the population experiencing vitamin D insufficiency. Around 42% of adults in the United States are afflicted with this condition.

Symptoms of Vitamin D Deficiency in Seniors

It is crucial to stay vigilant about the signs of vitamin D deficiency to ensure that older individuals receive the necessary nutrients for their well-being.

Symptoms of Vitamin D Deficiency in Seniors

Weak Muscles

As people age, they often experience muscle weakness that can lead to difficulties in standing up and climbing stairs, accompanied by a feeling of heaviness in their legs. This can be attributed to a significant deficiency of vitamin D, which plays a crucial role in the absorption and regulation of calcium, maintaining strong bones, muscles, and teeth. Insufficient vitamin D levels can weaken muscles and bones, putting older adults at a higher risk of falls and fractures. These injuries can be potentially life-threatening, making it vital to ensure adequate vitamin D intake in older age groups.

Changes in Mood and Cognitive Function

Vitamin D is a unique vitamin that functions differently in the body than other vitamins. It is transformed into the active hormone, calcitriol, which is essential for maintaining healthy immune function and regulating neurotransmitters that affect moods such as dopamine and serotonin. Research has revealed that low levels of vitamin D are linked to mental health conditions including seasonal affective disorder (SAD), depression, and schizophrenia. Moreover, older individuals who feel persistently fatigued and depressed might be suffering from vitamin D insufficiency or deficiency. Furthermore, insufficient levels of vitamin D may also increase the risk of cognitive decline and the development of Alzheimer’s disease and other forms of dementia.

Weight Gain

Emerging research suggests that Vitamin D plays a crucial role in regulating not only appetite but also body weight. Studies have indicated a negative correlation between lower levels of Vitamin D and obesity, while an increase in Vitamin D levels is associated with a decrease in body fat. It is believed that Vitamin D regulates the hormone leptin, which suppresses hunger and reduces fat storage. When an older adult is deficient in Vitamin D, the signaling pathways to the brain get disrupted, resulting in overeating and weight gain.


As we age, we may often feel fatigued and tend to dismiss it as a natural part of getting older. However, what we may not realize is that this constant tiredness could be a result of a lack of essential nutrients in our bodies. One such nutrient is vitamin D, which if deficient, can cause widespread pain in areas such as the shoulders, pelvis, ribcage, and lower back, leaving us feeling exhausted. If you experience stiff joints and persistent fatigue, especially if you don’t get enough sun exposure or fortified foods, it may be a good idea to consider increasing your vitamin D intake.

Digestive Issues

Emerging research has suggested a correlation between insufficient vitamin D levels and the onset of inflammatory bowel disease (IBD), a chronic inflammation of the digestive tract. This debilitating condition manifests in two distinct forms – ulcerative colitis and Crohn’s disease. Additionally, the malabsorption of dietary fat, a common consequence of GI disorders, exacerbates nutritional deficiencies of fat-soluble vitamins such as vitamin D, further compounding the already challenging symptoms of IBD.

How is vitamin D deficiency treated?

To achieve and maintain a healthy level of vitamin D in your body, whether it be for treatment or prevention of deficiency, there are various options to consider. While consuming vitamin D-rich foods and spending time in the sun can be helpful, your healthcare provider may recommend vitamin D supplements to ensure adequate levels.

Vitamin D is available in two forms: D2 and D3. D2, derived from plants, requires a prescription, while D3, found in animal sources, can be purchased over the counter. It is important to note that your body absorbs D3 more efficiently than D2.

Consulting with your healthcare provider to determine if a vitamin supplement is necessary and the appropriate dosage is recommended to optimize your vitamin D levels.

Final Verdicts

Vitamin D is a vital nutrient that plays a crucial role in maintaining optimal health, and insufficient levels of this nutrient can lead to serious health complications. Unfortunately, the symptoms of vitamin D deficiency, including tiredness, discomfort, and mood changes, are often misinterpreted as normal signs of aging. If you observe any of these symptoms in your loved one, it is essential to seek medical attention promptly. A routine blood test, along with recommendations for lifestyle changes and an over-the-counter vitamin D supplement, can effectively alleviate these symptoms and enhance seniors’ quality of life.
